Cold floor directly above the garage? Drafty basement that never feels fully heated? These rooms often got skipped during original construction, especially in older Boise homes.
Garage and basement spray foam insulation targets rim joists, wall cavities, and ceilings in these specific spaces. Boise Spray Foam Insulation Pros matches the foam type to the zone, closed-cell below grade, open-cell where moisture isn't a factor.

Moisture-resistant foam for below-grade basement walls, standard for below-grade applications in this climate.
Garage Door Seal Kits
Weatherproof seals around the garage door frame, a common draft source.
Open-Cell Ceiling Foam
Lightweight foam for garage ceilings and shared walls where moisture is less of a concern.
Protective Floor Sheeting
Protects garage and basement floors from overspray during application.
Mold-Resistant Coating
Applied in damp basement conditions to inhibit mold growth on foam surfaces.
Insulated Access Panels
Maintain insulation continuity around utility openings in these spaces.

FAQs
Garage And Basement Spray Foam Insulation FAQs
Can spray foam insulation help with my high winter heating bill?
Uninsulated garages and basements are common heat loss points. Sealing them with the right foam type often shows up directly in lower winter bills.
What's the difference between open-cell and closed-cell for these areas?
Basement walls sit below grade and face moisture, so closed-cell is the standard there. Garage ceilings with living space above are usually fine with open-cell since moisture isn't as much of a concern.
Which rooms benefit most from this service?
Rooms directly above an uninsulated garage and basements with visible drafts or cold walls see the most noticeable difference.
Is there a moisture concern with foam in a basement?
Closed-cell foam actually resists moisture well when applied correctly. The bigger concern is addressing any existing water intrusion before foam goes on, which we check during the site visit.
What does this typically cost?
Pricing depends on square footage, cell type, and ceiling height or access difficulty. A free estimate gives you a number specific to your space.
