Closed cell spray foam typically performs best in our climate because it provides both high R-value and air sealing in one application. However, the right choice depends on your specific building, budget, and goals. We can evaluate your property and recommend the best options.
Common signs include uneven temperatures between rooms, high utility bills, cold floors, and ice dams forming on your roof. If your home was built before 1990, it likely has less insulation than current standards require.
Yes, we can install blown-in insulation through small access holes in exterior or interior walls. This method works well for older homes that have little or no wall insulation.
When properly installed, spray foam insulation can last the lifetime of your building, typically 80 years or more. It doesn't settle or degrade like some other insulation materials.
Absolutely. We install insulation in barns, shops, equipment storage buildings, and other agricultural structures throughout Sanders County and surrounding areas. Spray foam works especially well for these applications.
