"I worked with Sean and his team on a large basement renovation as well as a few smaller projects throughout my clientâ s home. I found him to be professional, reliable, respectful and extremely competent in completing the project. We were especially appreciative of how inventive the team was while trying to combat specific issues we ran into. We had a set timeline and everyone did a great job ensuring things were organized and ran according to schedule. I highly recommend Sean and his team for any home renovation project! My client was beyond happy with the service provided."

"Costs increased about 10% over estimate, work was well done and the final product was professional and well-built. Communication could have been better, the builder promised weekly meetings but that didn't happen. All in all, we were happy at the end of it all, and all questions were answered and all finishes to our satisfaction, which if you've ever worked with a contractor before, you know isn't a given. 5/5 would work with them again, the fireplace mantel and threshhold was particularly well done."
