Basement & foundation spray foam insulation
Stop ground cold and moisture at the concrete before drafts chill your main living floor.
Below-grade walls and upper rim joists are the most vulnerable entry points for Canadian winter drafts and ground humidity. Conventional fiberglass batts allow warm indoor air to reach cold concrete surfaces, causing hidden condensation, rot, and mold behind drywall. High-density 2 lb closed-cell polyurethane spray foam cures instantly against masonry substrates, providing superior R-value, an airtight seal, and code-compliant vapour protection in one application.
Rim joist air sealing
Expands tightly into perimeter header cavities where traditional batt insulation sags and leaks outdoor air.
Vapour retarder & moisture control
Closed-cell foam forms a continuous barrier that blocks damp ground moisture and stops condensation on cool masonry.
Substrate monolithic bond
Bonds directly to poured concrete, cinder block, or historic stone foundations with zero gaps or shifting.

Why insulate your basement with spray foam
Stop moisture at the foundation wall, keep your main floors warm, and reclaim your lower level for clean, dry, year-round living.
Moisture control
Closed-cell spray foam seals subterranean humidity out of your foundation walls. It blocks damp earth odours and prevents mould spores from spreading through your living space.
Energy efficiency
Stops heat loss at rim joists and foundation headers where traditional batting fails. Your furnace runs less, and drafty main-level floors stay consistently warm all winter.
Year-round comfort
Eliminates the cold, clammy basement chill. Your lower level becomes dry, usable square footage suitable for a home office, recreation room, or dry storage.
