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

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.



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!

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!

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.

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.

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!

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


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! 

Finished Basement

Madeline and Chris

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.
