Insulation & Air Sealing · Basement & Crawl Space
Comfort Starts Below Your Feet.
Basements and crawl spaces can contribute to heat loss, cold floors and uncomfortable indoor conditions. Insulation and air sealing improve them, once any moisture issues are addressed.
Materials
Materials we use.
Existing water or moisture problems must be corrected before insulation work conceals them.
Rigid foam board
Commonly fixed against foundation walls; handles contact with concrete well.
Spray foam
Insulates and seals uneven foundations and rim joists in one step.
Mineral wool and fiberglass
In suitable framed assemblies, with the right moisture control.
What we consider
Done right for your home.
Foundation walls
Insulated in a way that suits the foundation and keeps it dry.
Rim joists
The band above the foundation, a common source of drafts.
Crawl spaces
Treated as part of the building envelope.
Condensation and vapour control
Chosen so moisture can’t build up inside the walls.
Water intrusion
Leaks and seepage fixed first.
Warmer floors above · A more comfortable, usable lower level

Questions
Frequently asked questions
What insulation is suitable for basements?
Rigid foam, spray foam, and mineral wool or fiberglass in suitable assemblies. The right one depends on the foundation and moisture.
Can spray foam be used on rim joists?
Yes. It is a common choice because it insulates and seals the gaps at the same time.
What if my basement gets damp?
The water or moisture problem is fixed first. Insulating over it can trap moisture and cause damage.
