We just had the team at Catalyst complete an addition to our home. I can't say enough good thing about our experience with Catalyst Construction. Many of our friends that have had work done by other contractors, told us that we were in for a terrible experience! We did get several estimates from other contractor but they were not very professional ! However, when Brady visited us to discuss our renovation, he was professional right from the get go! Myself being in the service business recognised right from the start that this man knew what he was doing. First he wouldn't just bounce a price off us, he explained that we would need a drawing and a professional plan, which he said he would provide then he could work from it to give us a firm cost estimate. Once this was done he gave us a price and schedule for the start and completion of the work, which I might add was right on! As a matter of fact they completed everything two weeks early! and right on Budget!. This is one area that I was told to look out for " EXTRAS " there were no unexpected extras. Although like many company's Catalyst use a variety of sub-trades in addition to there own staff. I must say that each and every one of the workers where very accommodating and helpful throughout the whole building process. The quality of the workmanship was and is exceptional . A special thank you and recognition go out To Jamie the project coordinator who walked us through each step of the process and to Chad, as the Foreman on site, he personally did an outstanding job of installing the stone Fire place, which is the centre piece of the whole room. In closing I can say without reservation that We are very pleased with the final result and thank all the staff and management at Catalyst, they have provided us with an outstanding new area that will add years of living enjoyment to our home. I highly recommend them to anyone looking to have work done at there home.

Sun-room Addition

Doug & Gloria

Catalyst just completed a major gut and rebuild of the second floor of my century home. This included rewiring of the entire home's electrical system, new insulation on the second floor, and new hardwood throughout the house. One of the existing bedrooms was transformed into a family bathroom and the existing bathroom was reconfigured as an en suite to an enlarged master bedroom. The project lasted 2.5 months, slightly longer than the estimated timeline of 2 months. This was justified, however, due to structural issues in the floor joists that were not visible until after demolition. Catalyst provided outstanding customer service. Andrew and Jamie were the my main contacts and both were kind, helpful and very professional. The project ended up being slightly over budget due to the structural issues and some asbestos and lead paint that needed to be abated. However, this was clearly discussed with me as a potential issue before demolition began. I recommend Catalyst without hesitation.

Full Home Renovation


Can't say enough positive things about Catalyst and their team! We had worked with a local contractor 3 years prior and weren't thrilled with their quality and thus were nervous. We hired them to turn our unfinished walkout basement into an apartment creating a legal duplex in Kitchener. We had several quotes from other contractors, including contractors who had done several duplexes in the past. We decided to go with Catalyst based upon their customer service. Communication was extremely important to us as we had recently moved and started new jobs 1.5 hrs away and could only come to the site 1/week. Unlike the other contractors we had quote for us who took 3-4 business days to answer our questions about their quotes, Catalyst presented the quote in person, with warranty, customer reviews, WSIB and Insurance certificates. They responded within the business day to other questions we had come up before we hired them. During our reno they kept us updated almost daily about progress, responded to our texts and phone calls, usually within a few hours! Unfortunately, as to be expected with every reno we had some unexpected things pop up such as finding asbestos and our air conditioner was recommended to be replaced as we had redone the HVAC for the entire house. Catalyst provided us with options and helped us price out solutions. Overall they stuck to our tight timeline to have tenants in April 1st and came in on budget. The finish product looked amazing and our house reappraised for significantly more than we were expecting! About a week after we had paid them in full our tenant called around 7am to say she had water in the utility room. Since we lived so far away we were concerned it could turn into a major issue quickly and thus called Catalyst who had done the work. They returned our call immediately and sent out one of their team to investigate the problem and bring shop vacs and dehumidifiers. They were onsite by 8am and had the problem fixed before we arrived from our 1.5hr drive. The problem was extremely minor our tenant had done an excessive amount of laundry and the dryer vent had become disconnected causing condensation to accumulate on our utility room which was mopped up with a towel. They re- taped and bracketed the dryer venting to prevent the issue from occurring again. We were a little embarrassed to have had them come out for what turned out to be such a minor issue but thankful for their response as we lived so far away. They stand behind their 2 year warranty. We hope to work with Catalyst again if/when we buy our 3rd income property.

Basement Apartment

Sarah and Ryan

After moving into my new house in the spring of 2015, I was on the lookout for a reputable contractor to replace the existing detached garage. Due to my yard, spacial considerations were a factor, though I still wanted something that would house my cars and look ecstatically pleasing from the road.

As part of the process, I met with a number of contractors before I met with Andrew and Brady from Catalyst General Contracting. Right away, they understood my needs, and made suggestions on how best to accomplish my goals and fit my budget. We discussed options and limitations, and arranged to meet again in order to bring a draftsman and have plans drawn up.

As others have mentioned, communication is a big part Catalyst's business success. Looking back, I see over 90 emails of correspondence between us - everything from confirming details, to scheduling advisements, to following up to see if I was satisfied. While that many emails may seem excessive for a simple garage, let me tell you, at no point was I ever in the dark. Any questions I had were promptly answered, and I was informed of every step in the process.

Once the actual build got underway, Catalyst contractors or sub-contractors were on the job site every day that weather permitted. All of their sub-contractors were courteous and professional, and left me with no mess to clean up afterwards. The garage came in on budget as agreed, and ahead of schedule. I couldn't be more pleased with the results, and have received numerous complements from neighbours and strangers alike.

Everyone knows the old adage 'You get what you pay for', and with Catalyst, you certainly get your money's worth. I will not hesitate to contact them again for future renovations, both inside and outside of my house. Thank you Andrew, Brady and Jamie!



We have had Catalyst General Contracting in to do the framing and other work for our separate three car garage, which is 27′ x 36′. Brady and Andrew did an excellent job. Everything was square and plumb, the job was done in the time they said it would and it came in right at the estimated price.

Even more importantly, Brady and Andrew listened to our requests, provided good advice, and did things to our benefit, not just their own. I would rate them very highly



Andrew and Brady did a fantastic job. My wife and I hired them to finish our basement with a quick time-line before expecting our baby and didn’t think it would be possible to have everything done in time. The whole experience was outstanding, we were kept in the loop throughout the project and it was completed exactly when they said it would be ready. We even have a few weeks to spare before the baby and visitors arrive to use the new room. The finished basement exceeded our expectations and is now highly used.

I would highly recommend Andrew and Brady and will definitely contact them again for the next project.



Catalyst did an excellent job on our upstairs renovation. They were friendly, receptive to questions and suggestions, detail oriented, efficient, and great problem solvers. All of the work looks fantastic, and it was clear that they took pride in doing things the right way. Best of all, they were very reasonably priced. We’d recommend them to anyone, and we’ll be having them do more work for us.

Mathieu and Megan

We hired Catalyst General Contracting to complete our basement renovation in May 2010. After receiving numerous quotes we felt that the quote from Catalyst was competitive, detailed and very professional. Our communication with both Andrew and Brady prior to and upon signing the quote made us feel confident that they would complete the job in a professional manner.

Throughout the process we were kept involved and updated on the progress of the work. The end result was a basement renovation that came in on-budget as quoted in a timely manner. We would highly recommend Catalyst. They are knowledgeable in the construction trade and take pride in the work they complete. We wish them success in all that they do.

Thank you!


Deanne and Andrew

Catalyst was referred to me by a friend of mine who highly recommended them, and they didn’t disappoint. I’ve had them do tile work, dry-wall, plumbing, etc and they have done an excellent job with it all. They were always on time, kept the work area very clean, and were always on budget.

I have had other contractors in the past who seemed like they were looking for ways to pull-one over on me from the first day, and it was refreshing to have someone do what they say and do it correctly. Catalyst was very honest and up-front.

I wouldn’t hesitate to recommend Catalyst to others.

I hired Andrew and Brady to renovate my kitchen and bathroom while my wife and I were away. Upon my return, I could not have been happier with the work that was done. Everything was completed on time and on budget. Any questions that I had about their progress were answered in a timely manner during the duration of the project. They even took the time to come by a few days after the job was finished to resolve a couple of minor issues free of charge. I highly recommend Catalyst.

Kitchen and Bathroom


I’m so delighted to have had Andrew and Brady from Catalyst do work on my home. We’ve been doing some major renovations over the past couple years, and it was great to switch over to using them. They were professional, hard-working, and committed to doing quality work. Having contractors with such breadth of expertise and experience was such a benefit for us, because we knew that the work would get done, at a fair price, and that you could not only “do it all”, but communicate with us throughout the process. From the excavation and installation of new concrete floors to the final drywall finish, it was great working with you! Thanks so much!



We used Catalyst to finish a portion of our basement. Brady and Andrew came across very professionally during the quoting stage of the project, and carried that professionalism throughout the job. They worked hard, were very responsive, and left our house clean. Whenever an occasional minor issue arose, they rectified it immediately. Overall we are thrilled with our basement, and Brady and Andrew surpassed our expectations with respect to the level of service we expect from a contracting company!


Terry and Sandy

Catalyst did excellent work renovating my bathroom. I have already obtained a quote from them to complete additional work at my residence. Catalyst worked late nights and even on the weekend to stay on schedule. They were courteous and kept me informed on the progress of the project routinely.



Our son recommended Catalyst to us this past spring. They had done a basement improvement at his home and he could not say enough about the quality of work that was done by Catalyst.

We hired Catalyst in the spring of 2011 to help us with our ensuite bathroom renovation. This involved a total gutting and remodelling of the room, which meant lots of construction traffic up the stairs and through our bedroom. We were impressed with the care and attention that Andrew, Brady and their sub-trades took, they kept everything from the carpet to our bed as clean and dust free as possible on a daily basis. Brady and Andrew worked with us to design exactly what we wanted and the quotation was detailed and realistic. Any questions or concerns were dealt with quickly and resolved to our satisfaction. The job was completed in a timely manner and we are thrilled with our new bathroom. The reaction from anyone who sees it for the first time is “wow” as they love the shower, the flooring, the vanity and the granite counter top. We wouldn’t hesitate to recommend Catalyst to help you with your renovations. As the company logo states Catalyst is “The Contractor You Can Trust” is a true reflection of both the Company and their work ethic.

Thanks again Brady, Andrew and staff, it is a real pleasure to offer this recommendation and referral.


Don and Beth

Our wonderful experience with Catalyst General Contracting began with the proposal process. Andrew walked with us through it, listening to our desires and our concerns. He heard our cost limitations, gave us some choices and suggestions and he understood what we wanted to achieve for our project. We were glad that he brought product samples with him to our initial meeting so we could make decisions right away. He provided us with a comprehensive, detailed cost estimate, which had several options for the scope depending on how much work we wanted to complete this year. We agreed to a price and the contractors started material ordering and construction as soon as possible in order to expedite the process.

Catalyst provided us with frequent updates and photos of the work completed, which was very reassuring. The flooring they installed looked better than the work the original builder had done and we could tell right away that Catalyst has a very high standard of quality and care. They also repaired some plumbing and installed a fence after guiding us through the utility locate procedure. We especially appreciated the extra hard work they undertook to install the fence around the back yard, which was difficult due to the hard, rocky soils typical to the area. Their professionalism, hard work, and the good-natured spirit of all the workers really facilitated the renovation process. They also did a great clean-up job and completed the work on schedule so that we could get new tenants in the house before September.

We will not hesitate to recommend Catalyst General Contacting to everyone in need of a professional contractor who delivers high-quality work.

Thank you for a job well done and best wishes,

Andrew and Lee

I hired Andrew, Brady, and their team to renovate my kitchen and bathroom. Both rooms were originally just constructed from standard builder’s materials. Andrew and Brady transformed them into beautiful showpieces.

They brought in the best in the trades and coordinated them perfectly. The job was completed on time and on budget, even when I would make changes here and there.

I would highly recommend Catalyst.

John and Elaine

We approached other contractors for home renovations, but Catalyst was the most professional and prompt. Andrew and Brady laid out the plans for the work very clearly and addressed all the concerns we had. We felt the same trepidation that anyone feels when you go with people you haven’t worked with before, but in the end they met or exceeded every expectation we had – for us, that meant a lot. We would recommend (and do so for our friends/family) Catalyst for any home renovation project. When we next decide to do any home renovation, choosing the contractor will no longer be a process filled with uncertainty and dread – Catalyst will be the only choice for us.

Brennan and Khim

We’ve lived in our home for over 23 years. Over that time, our unfinished basement became a catchall for everything that we didn’t use on a daily basis. Needless to say, we had a lot of stuff but very little usable area. We decided to take the plunge and hire a contractor to create a brand new space with lots of storage and functionality. After coming up with some design ideas and meeting with several contractors, we hired Catalyst General Contracting. Catalyst worked with us to finalize our plans and make them a reality. As the project progressed, we were in constant communication with Andrew and Brady. This way, any questions or concerns were dealt with in an efficient, timely and professional manner. The entire Catalyst crew was respectful, accommodating and competent and always left the work site in a tidy condition. We are very pleased with our new living space and would highly recommend Catalyst as the contractor of choice for any home renovation.


Don and Barb
Kitchener, Ontario

I found Catalyst via an internet search of local contractors who built garages. Three contractors were asked to provide estimates, Catalyst was included because their site showed a garage similar to what we wanted. All three contractors provided initial estimates that were within 5% of each other, Catalyst got the business because Andrew was prompt to respond to our request for an estimate, spent more time reviewing the requirements, and provided a more detailed estimate of the job. We agreed upon a final design and price and the build started shortly after building permit was obtained. Throughout the build both Andrew and Brady were frequently on site and were also very accessible via phone or e-mail messages. The building was completed in a timely manner, with high quality, and at the agreed upon price. I was very satisfied with the entire project and would certainly recommend Catalyst. 



Catalyst GC has proved to be one of the best contracting experiences we have had. Brady and Andrew were truly professional from start to finish. Their crew and trades proved to be an extension of Andrew and Brady’s dedication to the customer and the work. Throughout the job, Catalyst gave attention to detail, thorough communication, and timeliness. We have recommended Catalyst to others and we will be using Catalyst for any future contracting needs.

Whole Home Reno (Design / Build)

Susan and Trevor

After getting quotes from 3 local companies, we chose Catalyst to design and build us a new backyard deck, and what a great decision that was.

We found them to be extremely professional, talented and most importantly, dependable.

We couldn’t believe how gorgeous the finished product looked. Their design and detailing of the deck was simply awesome.

We would recommend Catalyst to anyone and certainly will use their talents again.


Carla and Jean

As new parents, we were looking to increase the amount of living space in our house to allow for more space for our growing family.  With a newborn though, life was busy even before starting a basement finishing project.  From our initial proposal gathering stage, Catalyst stayed in touch and answered our questions, and were ready to plan the project as soon as we were. The whole process was easy and caused an absolute minimum of disruption.

Communication is key with any big project, and Andrew always stayed on top of our questions and was prompt and clear. He kept in touch with us via email, a huge benefit for us to help keep track of our progress (and because ringing phones and sleeping babies don't mix)!

Every issue we brought up was quickly resolved.  Questions for us were timely and minimal since the planning for the project was done well. We were able to get some additional plumbing work done and an additional coaxial cable line run on short notice and for minimal extra cost. 

Overall, our experience with Catalyst and the sub-trades they work with over the 6 weeks of our project was exemplary. The quality of work and communication from Catalyst General Contracting is high, and we've recommended them to a number of our friends.  


Jenny and Trevor

When we wanted to have a large, complicated cedar deck built, we talked to about a dozen possible contractors. We hadn’t heard of Catalyst but when we interviewed them, they came across as easily the most professional builder we had met. They asked lots of good questions and made some very good suggestions, showing they’d spent a lot of time already thinking of the project. It was an easy choice to select them.

The biggest surprise was yet to come. Catalyst worked on our deck for a month, sticking exactly to the schedule they’d laid out. The work was amazing and our finished deck is the best work we’ve ever seen. Throughout the project, Andrew and Brady kept us updated every single day, so we always knew what was going on.  And the final cost was exactly what they’d quoted.

Our deck is the envy of the neighbourhood and we couldn’t be happier with it. If we have any future building projects, we wouldn’t bother looking at other contractors. Catalyst is the best. Period.

Our project was ambitious, adding a second floor addition to an older property. Catalyst were calm and professional throughout the project, not least when adapting to the challenges of an older home and dealing with the inevitable weather. We appreciated Catalyst for their regular email updates and swift responses to all our questions, as well as the care they took of our property during construction. They provided quality work, with timely delivery, at a cost as quoted. Catalyst is a great team; friendly, reliable and hardworking. We would not hesitate to contact them again in future.

Second Story Addition (Design/Build)

Camilla and Jim

We hired Catalyst General Contracting to repair/replace some very old fencing located between our home and that of our neighbours. It was necessary for some of the work to be done from our neighbour’s yard. Brady took the time to address all of our neighbour’s concerns with regards to the possible wear and tear on his yard. Brady’s patience and ongoing communication with our neighbour put his mind at ease.

The entire crew at Catalyst was friendly, respectful, knowledgeable and very hard working. They even worked through the rain in order to get our fence completed. The job was done on time and on budget and the fence looks terrific.

Brady, Andrew, and the entire team at Catalyst did an incredible job. Their level of customer service and their workmanship is exceptional.

We highly recommend Catalyst.


Kevin and Anna

Good morning Andrew, I wanted to take a few minutes to personally thank you for all the hard work and dedication that you and your crew demonstrated during the renovation of our main floor and second floor. As you know, we previously hired a contractor recommended by a dear friend. He had completed a small 'handy man' type project in a previous house and we trusted him completely having met him socially on several occasions. He cashed our cheques and completed the work on our main floor in a substandard manner. The structural wall was not supported, the plumbing was completely by him as was the electrical even though we paid for trades to do the work. Neither work was done to code. Our kitchen was installed and that is when we realized that he had no idea what he was doing. Our daughter said it looked like the shop teacher gave the grade nine boys some tools (but not a level) and some really expensive nice materials and told them to see what they could come up with. We were left in a dire situation where we needed a reliable, professional, skilled contractor to take over the job and complete it correctly. We interviewed several contractors and decided to work with Catalyst because you are professional in every way. The cost was similar with others but your contracts are professional and protect both parties. We moved forward with the work and found your crew to be hard working and skilled. We are extremely happy with the results. You fixed the work the other contractor did improperly and allowed us to sleep at night knowing our second floor would not end up on the main floor and we would not go up in flames from shoddy electrical work that could have ended in a fire. As a result of the experience we had we found ourselves living in the house when your crew did the work. The entire experience was made easier as you and your crew cleaned up each day and kept your tools organized and tucked away. There were no surprises. I especially liked that when there were options on how to complete work you took the time to discuss possibilities and go over the costs and benefits of one approach verses the other. You even called to let me know that the toilet we chose for the upstairs bathroom did not look right and you felt we would be happier with a lower profile toilet. You did not fully attach it until we had a chance to see it and decide for ourselves. You were right and we are pleased with the second toilet we picked out. I suspect most contractors would just attach the toilet and keep going with the work, after all we did choose the toilet. The work completed is absolutely wonderful. I am picky and have high expectations and you exceeded my expectations. We still have a porch and a garage that need to be built and I will be calling you in the future to do this work as well. Thank you and your crew for the wonderful work, we now have a house we can enjoy for years to come thanks to your company!

The team from Catalyst was a pleasure to work with throughout our deck construction. Notwithstanding our lateness with the permit and three days of rain, they completed a big job from first to last in four and a half days in time for our anniversary party. We were really grateful. Andrew, Brady and their crew were prompt, courteous and competent in all aspects of their performance from paperwork to practicalities. We would use the company again and fully recommend their work.


Sarah and Scott

A big thank you to Brady, Andrew and the rest of the Catalyst Team for giving us the bathroom of our dreams! We weren't sure how we were going to survive the renovation of our main bathroom (and only bath/shower) with a 6 month old, but Catalyst made the whole process very easy (and were very accommodating to the needs of our daughter). Every member of their team was polite and professional. The job site was left clean and organized at the end of every day. Brady and Andrew answered any and all of our questions promptly. Best of all, the project was completed on time and on budget.

Catalyst General Contracting was professional, on time and on budget for our home improvement. The entire staff worked quickly and neatly to get our house back to us as soon as possible. I would recommend them wholeheartedly for your home improvement. We would not hesitate to use them again should the need arise.

We had a fairly tight schedule to finish the basement of my son’s townhouse.  Andrew was very prompt in putting together a quote and it ended up being the winning bid.  Andrew and Brady’s crew showed up when they said they would and were very courteous and conscientious.  They covered the entire lower floor in drop clothes to keep the dust and mess to a minimum.  I found Andrew’s suggestions to be superior to ideas that we had and the entire project was finished on time and on budget.  I would highly recommend Andrew, Brady and their team at Catalyst.

Finished Basement


We had wanted/needed to reface the entire outside of our house for several years but had interviewed several contractors and just couldn’t find anyone who could handle the size of the project, the details that I was looking for and inspire the confidence for me to move forward. I was referred to Catalyst in the early spring of this year having been told that they could handle the project. I called and Brady/Andrew came out to the house to discuss the project. They were amazing at helping me keep to my budget, worked and reworked the plans until it all came together and were extremely flexible when it came to making last minute changes as they came up. During the actual renovation, the entire team was prompt, curious, and professional the entire month that they worked on the house. I am so happy with the result and wouldn’t hesitate in recommending Catalyst to anyone else. I have to say they made a large renovation quite easy to live through. I would hire them again in a heartbeat for any future renovations. No more stress about finding a good, honest, and quality contractor! Thank you Catalyst. Keep up the great work!

Cheryl and Rob

We hired Catalyst to rebuild our old detached garage. They handled everything end to end: planning, design, permits, materials, demolition, construction, clean up and final inspection. The work was very high quality and was done according to plan, and we were very happy with the result. They were also very accommodating: designing and building custom doors, and working around the inevitable surprises that came up. The best part about working with Catalyst is the quality of communication - emails were answered quickly (often within a couple hours) and thoroughly. Keeping the communication channels open was crucial to our peace of mind during this ~5 week project. We also got electronic copies of all relevant documents, which was great for us. We would work with Catalyst again in the future.

Working with Andrew and Brady has been a pleasure, as they helped me realize long-held dreams to renovate the bathrooms and expand the back deck of my modest townhouse (with a number of other miscellaneous maintenance projects added along the way).  From the first interview with Andrew I was impressed with his enthusiasm, courtesy, professionalism, and credentials (engineer).  I immediately felt confident that I would be in good hands with Catalyst, a feeling I did not walk away with after meetings with other contractors.  I was equally impressed with Brady when I met him as the work progressed, and both partners (and their excellent crew) were adept at creative problem solving to ensure we made the best use of the small spaces I had to work with. 

I now have the most beautiful "tiny" bathroom imaginable, with a senior-friendly walk-in shower replacing the old tub/shower combo.  Andrew helped me find the perfect piece of granite for the custom shower bench and vanity top to go with the oil-rubbed bronze fixtures I had purchased.  All the trades people Catalyst brought in (tile, plumbing, electrical) were top notch professionals.

The real creative genius came in the design of my new deck -- what a transformation from the tiny 3-person deck that was standard to these townhouses!  Before I applied for the required building permit, Andrew smoothed the way by making contact with the Kitchener Planning Dept to find out what was possible (and not) in terms of an expanded deck project for my back yard.  Andrew and Brady were then creative in finding a way to use every square foot of space allowed within the required set backs.  This included arranging for Kitchener Utilities to re-position my gas meter and water meter readout.  All the guys at Catalyst that worked on my deck did a fantastic job, with a beautiful end result 2-1/2 times the size of my old deck.  After I gave them a bare bones wish list (a stone area for my charcoal smoker/grill), Andrew and Brady and their crew all made creative design enhancements as the work progressed.  The stonework landing at the bottom of the stairs is a beautiful addition, and a creative solution to the sloping grade there.  My custom deck will now be a great entertaining spot for years to come.  Thank you, Catalyst.



Early in the spring we contacted Catalyst Construction.  We wanted to build a deck onto the back of our house but we were not entirely clear of the design, materials to use or the details of the deck that would best meet our needs.  Andrew came to listen to our ideas, offered some suggestions and ideas and together we formed our early design.  Throughout the building process the design had some modifications which improved the visual appeal.  Things were going well so we added to the scope of the project.  At all times we were consulted to make choices.  The entire crew offered honest opinions, were respectful, knowledgeable, competent, personable and accommodating.  The subcontractors that were used to complete the specialized parts of the project were also knowledgeable, competent and personable.  We have had many projects completed over the years by many different companies that have not been asked back.  Our deck/roof/porch project was the most positive experience by a landslide.  We LOVE our new deck and so do all of our friends.  Thank you to the entire Catalyst crew.

Brady and Andrew,

Thank-you so much to you and your team for creating a space that we enjoy so much. Our basement was done in a fast and very professional manner. The employees that you have working with you showed us respect by keeping things clean and asking our opinions every step of the way. The noise was minimal and each day we came home to something new completed in our home. I was especially impressed with how smooth everything went and how fast the project was completed. You were able to communicate ideas to us in a very fast and efficient manner. My favourite part of the basement is the custom laundry and bathroom. I never thought I would ever say that I actually enjoy folding laundry but the space is so lovely I never want to leave! You have added so much value and useful space to our house and we can't thank-you enough. I would recommend your company, Catalyst, to anyone looking for home renovations. I know that if we get more work done in our house we will come to Catalyst. Thanks for being cooperative, friendly, and most importantly efficient in completing our basement!

I had them replace a basement window (that the previous owners covered up - why?) and they went beyond my expectations. They've also installed 2 skylights in my living room and renovated our main bathroom. We're currently getting a quote for my large kitchen eat-in area bay window. I was always notified when their team was coming, they cleaned up after themselves each day before leaving, and billing expectations were clearly presented up-front with no up-charging.

Once you find a contractor that provides work and service that match or exceed expectations, why look anywhere else.

We have used Catalyst in the past for a couple of projects which we were extremely pleased with. That is why we asked Andrew and Brady to assess a water leakage problem at our cottage. We completely trust their knowledge and capabilities. After extensive investigation and collaboration, Andrew and Brady determined the source of the problem and were hired to fix that and repair and renovate the damaged areas. Again, Andrew and Brady provided us with a detailed, knowledgeable estimate and their team completed the work on budget and in a timely manner. We were more than pleased with the results.

Bathroom & Structural Work


We hired Catalyst on two occasions to do some work on our rental property in Guelph. After several years of abuse by student tenants, our house needed a facelift and Catalyst expertly installed flooring throughout the top floor and painted the house, in addition to installing a fence in the backyard - best looking one on the block! Along the way, their staff made useful suggestions and cost saving tips, including the choice of flooring and other finishes.

Recently, we had some water damage due to a frozen pipe. We knew exactly who to call and Catalyst responded promptly with an estimate to replace the flooring, insulation, and drywall that was damaged. They knew exactly how to deal with the effects of water damage including spraying for mould and giving the basement time to dry out before replacing the insulation and drywall. They also brought to our attention potential hazards (wiring issues) - they're always on the lookout for the client.

They're great with coordination / communication and run a tight ship - we received frequent updates and they always asked for approval if any extras come up (as is typical during renovations). We won't even consider other contractors for future work at our property in Guelph - Catalyst is our first and only choice!

In a word, our experience with Catalyst General Contracting was "outstanding".

Our first meeting left us with a very positive impression of complete professionalism.

Subsequent meetings and conversations indicated a complete willingness to work with us on the various aspects of our ensuite renovations. The sub trades used, the quality of their employees and their overall demeanour was very confidence inspiring. The job was completed within budget and on time. 

In our opinion the most positive aspect was the daily communication we had with Brady regarding the progress of the job. We knew at the end of each day what the next steps were and when someone would be at our house. 

We couldn't be happier with the quality of the completed project and the overall experience.  


Denis and Regina

We have worked with Catalyst a couple times now, the first was a few years ago when we needed our basement finished. This time we renovated the main floor, including the removal of a load bearing wall and a complete redo of the kitchen. We were so happy with the experience of working with Andrew, Brady and the entire crew that this time around we didn't even consider another contractor.

The entire Catalyst crew and all subcontractors that they arranged were a pleasure to work with. They all put great care into their work to ensure a high level of quality with everything that is done. Communication was prompt and effective throughout the entire process, and they were always ready to listen to our input to ensure that we received an end product that we would be totally happy with. Last but not least the project was completed within the timeline and budget originally quoted.

I would not hesitate to recommend Catalyst GC to anyone and would definitely work with them again for any future projects around my own house.

Kitchen and Basement

Kitchener, Ontario

We partnered with Catalyst to rebuild the front of our house to our design after it was storm damaged; this included an almost 300 sqft second storey deck, on-grade ~200 sqft dyed concrete patio and formed steps, painting, electrical, and roofing work.

In Catalyst, we found a partner who did a wonderful job of getting our vision built. We had a general design, various specific elements that we cared very much for, and other elements that we very much depended on the builder to figure out and help us finalized. Clients have a great deal of responsibility for the success of the project — clients must inspect the work at every stage, must be paying attention to what happens next, must communicate if they spot something that may need rework; we believe we did this in this project, and that it allowed us to unlock the full potential of our chosen contractor.

Overall - Our house has more major projects that need to be done; we expect that Catalyst will be doing that work, when the time comes.

Financials - Catalyst provides firm quotes. They take the time to understand the project, and on that basis, provide a quote. We made a concerted effort to provide all possible details, and Catalyst rewarded us by not changing the prices as the job developed; in a couple of cases, Catalyst was forced to build differently than planned, but were within the core scope that had been agreed, but they stuck with the budget. Catalyst is not the cheapest, does not play games (such as “cash discounts”), provides proof of insurance, a plain-language contract, is paid through-out the project based on achieving agreed mile-stones, and uses Reno-Mii software to manage change requests - this keeps the details of the work to be done, and what it is supposed to cost tightly linked (if you can post updates on a Facebook post, you should be able to use RenoMii). It is easy to have a frank conversation with Andrew or Brady about exactly why elements of your project cost what they are quoted.

Scheduling - At project kick-off, based on a small deposit, Catalyst provided a firm start date. Catalyst started on that date, and was onsite virtually every day until the project was done, except for days during which weather-prevented work from being done. Catalyst provided a knowledgeable project manager, whom we were able to reach easily by email and cell phone, both during the day, and during evenings/weekends.

Work Place Management - Catalyst cleans up the work place at the end of the day, and leaves nothing lying around. On our outdoor job, Catalyst supplied things like outdoor porta-pottys so contractors are not tromping through the house for the washroom. Catalyst sends crews out with written lists of what is to be done on a given day, by whom, and noting any particular directions from the client.

Quality of Work - Catalyst does good work. Catalyst looks for opportunities to improve the build-quality of the design. If something doesn’t come together right, they will rework it. Catalyst knows the trades people they bring onto jobs. The trades people who work for Catalyst like working for Catalyst. Catalyst will meet with you as often as necessary to review the work — before work on major items that would be hard to change later, after something has been done, any time questions come up.

Track Record - We found Catalyst by way of a family member who had two jobs done; they gave a good review, and we'd like the look of the work well enough to ask who did it.

In summary, we're satisfied with what we achieved in this first project, and would hire them again.
