About Montgomery County

Montgomery County is known for its vibrant communities, strong environmental focus, and wide range of housing — from 1940s brick colonials to new townhomes and contemporary builds. While the region values sustainability, many homes still have aging insulation or leaky ductwork that drives up utility costs.

At Terrain Insulation, we help Montgomery County homeowners and landlords boost energy efficiency and indoor comfort through targeted upgrades like spray foam, attic insulation, crawl space sealing, and more. Whether you’re in Bethesda, Rockville, Wheaton, or anywhere in between, we deliver custom energy solutions — all supported by PEPCO rebates and Inflation Reduction Act incentives.
