Spray Foam Insulation in Kensington, MD

The Town of Kensington and the Kensington Historic District contain some of Montgomery County's most architecturally distinctive housing — late-Victorian gingerbread homes, Queen Annes, Shingle-style cottages, and Craftsman bungalows that line Armory Avenue, Howard Avenue, and Plyers Mill Road. These homes deserve insulation work done by someone who understands plaster-on-lath walls, historic windows that owners want to keep, and the importance of doing nothing to compromise architectural character. DMV Foam is Maryland licensed, MHIC credentialed, and historic-preservation experienced.

Insulation Types We Install in Kensington

Preservation-friendly systems matched to Victorian homes, Craftsman bungalows, and the surrounding mid-century neighborhoods.

Spray Foam Insulation

Targeted closed-cell at basement rim and crawl space, conditioned-attic systems for historic homes with limited attic depth.

Batt Insulation

Mineral wool acoustic batts for upstairs bedrooms, fiberglass batts for additions, garages, and basement finishes.

Cellulose Insulation

Dense-pack walls in plaster-walled Victorians without disturbing interior finishes. Blown attics over careful air sealing.

Fiberglass Insulation

BIBS for retrofit walls and blown loose-fill for attics. Cost-effective for the more modest 1950s-60s homes around Kensington.

Insulation for Kensington's Historic Housing

From Howard Avenue Victorians to mid-century ranches in Rock Creek Hills, Kensington spans more than a century of housing styles.

Victorian and Late-19th-Century Homes

The Kensington Historic District, designated in 1980, protects roughly 350 buildings dating largely to the 1890s through 1920s — Queen Annes, Shingle styles, Folk Victorians, and Craftsman bungalows arranged along Howard Avenue, Armory Avenue, and the surrounding side streets. These homes share a predictable set of insulation challenges: plaster-on-wood-lath walls without sheathing, original windows that homeowners want to preserve, vented crawl spaces with dirt floors, and attic floors with no insulation or settled cellulose. Our preservation-friendly approach is dense-pack cellulose in walls (drilled from the exterior siding side and patched cleanly with no impact to interior plaster), comprehensive attic air sealing followed by blown insulation to R-49, and closed-cell spray foam at the basement rim and crawl space. None of this affects interior trim, original windows, or historic character.

Historic Downtown Kensington and Antique Row

Downtown Kensington — particularly Howard Avenue's Antique Row and the surrounding commercial buildings — has its own insulation needs. We work on commercial fit-outs, mixed-use building roof decks, and preservation-aware retrofits for the older storefronts and the apartments above them. 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.

Mid-Century Neighborhoods Around the Town

Beyond the Historic District, Kensington includes substantial mid-century housing in Rock Creek Hills, Kensington Estates, and the streets along Knowles Avenue and Connecticut Avenue. These 1950s and 1960s ranches, split levels, and modest colonials were originally insulated to the standards of the day, which means under-insulated by today's standards. Our retrofit approach is the same dense-pack walls, blown attics over careful air sealing, and closed-cell at basement and crawl space rim joists.

Pepco Rebates, Federal Tax Credits, and Energy Audits

Kensington residents have access to Pepco's EmPOWER Maryland efficiency program, which includes Quick Home Energy Check-ups (often free), rebates on qualifying insulation through Home Performance with ENERGY STAR, and seasonal promotions. Federal IRS Section 25C tax credits cover 30 percent of insulation costs up to $1,200 per year. We provide all required documentation, including itemized invoices, R-value certifications, and Manufacturer Certification Statements.

Permits, Drive Time, and the Kensington Process

Kensington sits in Montgomery County, Maryland, and includes the incorporated Town of Kensington plus the surrounding unincorporated areas. All conditioned-space insulation work requires Montgomery County Department of Permitting Services (DPS) permits. We hold Maryland Home Improvement Commission (MHIC) licensing, pull permits on your behalf, coordinate inspections, and provide stamped documentation. For projects affecting the exterior of homes within the Town of Kensington Historic District, we also prepare the product and method specifications needed for Historic Preservation Commission review. Drive time from our Falls Church headquarters is approximately 30 to 40 minutes via the Beltway and Connecticut Avenue.

Most Kensington projects close in 1 to 2 days for typical attic and basement work, 2 to 4 days for whole-home retrofits, and 5 to 10 days for new construction or substantial rebuilds.
