About Wall Insulation Service
Walls make up the largest surface area of your home’s thermal envelope — and when they’re under-insulated or left uninsulated, you feel it in every room. That’s why our wall insulation service is one of the most impactful upgrades you can make. Whether you’re remodeling, finishing a basement, or insulating a new build, our team delivers solutions that boost comfort and slash energy waste.
Our process begins with a full inspection of your property’s wall systems. We assess existing insulation (if any), wall type (wood framing, masonry, etc.), and access points. For existing homes, we often use drill-and-fill spray foam insulation that’s injected through small holes in the wall cavity — allowing us to insulate without tearing down drywall. For new builds or gut renovations, we offer full cavity spray foam application for maximum coverage.
We specialize in both open cell and closed cell foam insulation, depending on your goals. Open cell foam provides excellent air sealing and soundproofing — ideal for interior walls and shared rooms. Closed cell foam offers superior thermal resistance and moisture control, making it perfect for exterior walls in climates like Northern Virginia and Maryland.
As an experienced spray foam insulation contractor, we work on both residential and commercial projects, including apartment complexes, office buildings, and single-family homes. We’ve helped clients in Arlington, Rockville, Chevy Chase, and more achieve cleaner indoor air, quieter rooms, and lower heating and cooling bills.
