Foundation Insulation
Exterior and interior foundation insulation for a warmer, drier basement
A premium take on foundation insulation
Uninsulated concrete is one of the biggest sources of heat loss in a Quebec home, and cold foundation walls are where basement condensation and musty smells start. We insulate foundations from the outside, with rigid insulation and a protective membrane installed while the wall is excavated, or from the inside as part of a basement renovation. Doing it at the same time as a French drain replacement means you only pay for the excavation once.
This service is a good fit for homeowners and property managers who want a clean, professional result without juggling the details themselves. We handle the prep, the finish work, and the cleanup so the space is ready to enjoy when we're done.
Every project covers the essentials
- Exterior rigid insulation on excavated walls
- Interior insulation as part of basement finishing
- Waterproofing membrane and protection board
- Rim joist sealing and insulation
- Coordinated with French drain work to share excavation
- Less condensation on basement walls
