Basement Renovationsin Montreal
Turn your unfinished basement into a family room, home office, in-law suite, or legal rental unit. We handle framing, insulation, electrical, plumbing, and all permits.
The Problem We Solve
Why homeowners in Montreal choose us
An unfinished basement is wasted space in one of Montreal's most expensive housing markets. Many homeowners delay the project because they are not sure where to start, who to call, or what it will actually cost. Others have started and run into moisture problems or permit complications that stalled the project. We bring a clear process, realistic pricing, and the trades to complete the job - including handling every permit requirement.
