Finishing a basement is one of the most effective ways to add living space without building an addition: a family room, office, guest bedroom, bathroom or space for relatives. In the Montreal area, a well-renovated basement must also deal with moisture, sewer backups and cold.
A basement project involves several trades: framing, insulation, electrical, plumbing and finishing. Comparing several detailed quotes helps you spot the differences. With estimations.pro, one request lets you receive up to 4 quotes.

Our basement tips
- Moisture first: fix leaks, foundation cracks and drainage before finishing the walls.
- Backwater valve: make sure one is installed and accessible. Some municipalities require it.
- Radon test: Health Canada recommends testing for radon, especially if you plan to live in the basement.
- Basement bedroom: a bedroom needs a window that allows emergency exit. Check your municipality’s requirements.
- Right flooring: choose flooring that tolerates moisture.
Preparing your quote request
Give the approximate area, the height between the floor and the joists, the rooms you want and whether there has been water infiltration. If possible, include a simple sketch and a few photos of the walls, floor and electrical panel.
