With its cobblestone streets, 19th-century facades, and premium property values, Georgetown is one of Washington, D.C.’s most iconic neighborhoods. But behind the charm, many homes suffer from outdated insulation, inefficient HVAC systems, and limited airflow — especially in attics, crawl spaces, and walls.
At Terrain Insulation, we bring deep expertise in historic energy retrofits, offering smart upgrades that improve comfort and reduce utility bills without compromising the craftsmanship or layout of your home. From spray foam for hidden cavities to discreet duct sealing, we help Georgetown homeowners modernize their energy performance — while protecting what makes their homes unique.
If your Georgetown home has inconsistent temperatures, frequent drafts, or high utility bills, chances are your insulation is outdated — or missing entirely in key areas.
Our audit includes a detailed review of insulation, air leakage, duct condition, and HVAC performance — using non-invasive diagnostics to respect older structures.
We work directly with PEPCO, SMECO, and BGE rebate programs, and help Georgetown residents access incentives even in historic zones, including for heat pumps, duct sealing, and attic insulation.
