Spray foam, blown-in, and batt insulation for Larimer County homes and businesses — installed by a local, family-owned crew with 23+ years of experience.
We respond within 24 hours.
Larimer County spans a remarkable range — from suburban Fort Collins and Loveland to the mountain cabins and year-round homes around Estes Park. That variety means there is no single insulation solution for the county. Suburban homes often need attic retrofits and air sealing to address settled fiberglass and thermal bypasses, while mountain cabins and foothills homes face deeper cold, snow load, and ice-dam risk that call for closed-cell spray foam in crawl spaces and rim joists. Communities like Wellington, Berthoud, and Timnath mix new construction with older housing stock, each with its own insulation gaps. Because we're based right here in Larimer County, we understand the local climate, common builder practices, and the rebate programs available through utilities like Fort Collins Utilities and Efficiency Works. Every project starts with a free on-site inspection so we can measure your actual R-values, find where heat is escaping, and recommend the right products with an honest, upfront price.
Rebates: Larimer County residents may qualify for rebates through Fort Collins Utilities or Efficiency Works — we'll check current eligibility for you.
