Local Insulation
Spray foam built for Plains weather
Winters in Sanders County are long, cold, and hard on a building envelope. Closed-cell spray foam is the single best product we install for Plains homes and commercial buildings. It seals air leaks, controls moisture, and locks in R-value the year you install it and every year after that.
We do the install with local crews who live and work in our service area, not subcontractors from out of state. That means we show up on time, we know the codes the MT inspectors actually enforce, and we are around if you need us after the job.

What spray foam fixes for Plains buildings
Cold floors and drafty rooms
Closed-cell foam on rim joists and in the crawlspace fixes the cold-floor problem most Plains homes deal with every winter.
High heating bills
A sealed, foamed envelope drops monthly heating cost noticeably, often the largest single utility savings a homeowner sees.
Metal building condensation
Closed-cell foam on the underside of metal panels eliminates drip and corrosion in shops, ag buildings, and warehouses.
Ice damming on the roof
Air-sealing the attic plane with foam stops the warm-air leak that causes ice dams in our climate.
Sound transfer between rooms
Open-cell foam in interior walls drops sound transfer dramatically. Great for bedrooms, home offices, and short-term rentals.
Cold storage and refrigeration
Closed-cell foam is the right insulation and vapor barrier for refrigerated rooms and walk-ins.
