Insulation Contractors in Sumpter, OR — IECC Zone 4C · 4.5k HDD/yr

Sumpter, OR sits in IECC climate zone 4C and averages about 4.5k HDD per year, which sets the attic and wall R-values local crews should be quoting. Homes here are about 42 years old on average and carry a median value near $465k, so retrofits usually mean topping up thin attic insulation, air sealing, and checking for missing wall or crawl space coverage.
