What Homeowners Say
GSG excell on the work done. Very recommended.
Very professional, always on time, reasonable price and highly recommended for flooring and windows and doors.
Thank you Sebastien for painting my house and renovating my bathroom and kitchen. You did amazing on the tiles and backsplash, you followed my vision. You are easy to work with and met the deadline. Highly recommend 10/10 well organize
I contacted Sebastien about building me a privacy fence & gate to keep my doberman safe in the backyard. This was right around another contractor took $450 from me & never showed up again, so I was quite weary, but Sebastien came across as a very ernest man, so we shook hands on the project. He is a master carpenter, and his love for woodwork is evident in the care he took to build something he is obviously happy about. In the end, he made us a beautiful sliding gate that will be the envy of my neighbours, I’m sure! Very please with the project, and definitely would recommend him.
