When I went on the quest for an organization and general contractor to build my custom home I must admit I was terrified and overwhelmed. I interviewed a couple GCs and I did not feel that they had my interests at heart. A friend whom had recently completed the construction of a custom home in Oakville recommended Lucas from Gencorp Homes. I was hesitant, at first. My concerns were two fold. My project was in Forest Hill, midtown Toronto and the project was very high end. I debated using someone local or using the recommendation of Gencorp from my friend. I ultimately went with my friends recommendation who said ” you will not regret it”. Read More…

Lucas has been absolutely invaluable to our whole home build. His patience, knowledge, contacts, high quality trades and collaborative ideas have helped us build our dream home on time and on budget. Thank you Lucas, we look forward to working with you again for the next one!

~ Ashley Eikerman

We are very happy with the extensive renovation GenCorp Homes Inc. was able to do to our home. It was a 6 month project that they were able to complete in 6 weeks. All the trades used were great to deal with and very experienced. Lucas Munn was always present to make sure things were being done as promised and always very accommodating to our requests, questions and changes along the way. Offering the best of advice and guidance to complete the job in the most professional manner and very pleasant to deal with, we would highly recommend Lucas for any building or renovation project.

~ Louie Carnevale

Lucas is a rockstar. We closed on a house mid-July. We were trying to sneak in a few small renovations before we moved in at the end of the month. Everything was absolutely perfect and we ended up MOVING IN EARLY!! Absolutely unheard of with construction. I was floored. The quality of workmanship was absolute perfection.

~ David Tile

I hired Lucas in 2019 to manage a large high-end home in a premium neighbourhood in Mississauga. My experience with Lucas was fantastic. Not only did he complete this challenging project on time and on budget, but his management skills, construction knowledge, integrity and commitment to excellence have made the process enjoyable and stress-free. If I had to do it all over again I would re-hire Lucas in a second.

~ Barry S.

Lucas was an absolute pleasure to deal with. He was extremely professional and kept me informed at all times as to how my project was coming along. The installers were fantastic and the finished project far exceeded my expectations . I would not hesitate to recommend Lucas to anyone and I would definitely contact him again if I have any other projects.
