Done properly

A finished basement starts with a dry one

Montréal basements come with their own challenges: humidity, low ceilings, old foundations and mechanical rooms in the way.

We check for moisture first, then insulate, frame and finish with the right materials for below-grade spaces — so the room stays comfortable all year.

FAQ

Basement renovation questions, answered

Finishing a basement of about 600 sq ft typically costs $35,000 to $70,000+ before taxes, depending on bathrooms, number of rooms and any moisture work needed first.

Most basements take about 4 to 8 weeks of work. Adding a bathroom or fixing moisture issues can add time.

Usually yes — finishing a basement adds or changes rooms, which requires a permit from your borough. We prepare it with you.

Yes. Depending on your drain depth, we may need a pump system. We check this during the site visit.

We look for signs of moisture first and address them before insulating, then use materials suited to below-grade walls.
