Chevy Chase Spray Foam, From Historic Basements to Tear-Down Rebuilds

Chevy Chase has two distinct spray foam markets, and we serve both. The first is the steady stream of tear-down rebuilds and new construction along Connecticut Avenue, Brookville Road, and the side streets that radiate from them — large, architecturally ambitious homes where comprehensive closed-cell spray foam systems are the standard. The second is the historic preservation work in Chevy Chase Village, where we use spray foam strategically — closed-cell at the basement rim and crawl space walls — without affecting plaster walls, original windows, or historic character. Maryland-licensed, MHIC-credentialed, with a track record of working alongside premier Chevy Chase architects and builders.

Comprehensive Closed-Cell for Tear-Down Rebuilds

For new construction and substantial rebuilds in Chevy Chase, our standard recommendation is a comprehensive closed-cell system: foam at all exterior walls (typically 3 inches for R-21), basement walls (3 to 4 inches for R-21 to R-28), the rim joist at every floor level, and the underside of the roof deck (creating a fully conditioned attic). This combination delivers Energy Star or beyond-code performance, qualifies for the highest tier of federal IRS Section 45L Energy Efficient Home Credit and Pepco EmPOWER rebates, and gives the homeowner a tight, comfortable home with predictable HVAC sizing and dramatically reduced operating costs. We coordinate scheduling with the GC, architect, and HVAC contractor to confirm thermal boundaries and code-compliant ignition or thermal barrier placement.

Targeted Spray Foam for Historic Chevy Chase Village Homes

For historic homes in Chevy Chase Village and other early 20th century properties, spray foam plays a more focused role: closed-cell at the basement rim and crawl space walls, where moisture and air leakage cause the most damage to vintage structures. None of this affects interior plaster, original trim, or historic character. We work alongside dense-pack cellulose installers (often us, in walls) to deliver complete thermal envelopes without compromising preservation. Where Historic Preservation Commission approval is required for any exterior-facing work, we provide product specifications, ICC-ES reports, and installation method documentation for review.
