Cellulose Insulation in Chevy Chase, MD

Cellulose is the right answer for the historic homes that define Chevy Chase. The Tudor revivals, Colonial revivals, Arts and Crafts cottages, and grand Victorians of Chevy Chase Village were built between 1890 and 1930 with plaster-on-wood-lath walls and no original wall insulation. Dense-pack cellulose reaches every cavity void without lifting a single piece of interior plaster, surrounds the wires and pipes that batts cannot accommodate, and delivers full thermal coverage with no impact to historic character. The fiber is made from high recycled-content paper treated with borate compounds for fire resistance and pest deterrence — historically appropriate, environmentally responsible, and effective for over 80 years of installations across the country.

Dense-Pack for Chevy Chase Village Historic Homes

Before any cellulose goes into the walls of a historic Chevy Chase home, our crews confirm there is no active knob-and-tube wiring in the cavities — a safety check we perform on every pre-1940 home in the area. We then drill small access holes from the exterior siding side (often beneath the next clapboard so the patches are completely invisible after refinishing), fill the cavity to 3.5 pcf, and patch cleanly. The work has zero impact on interior plaster, original trim, or historic windows. Where Historic Preservation Commission approval is required for the exterior work, we provide product specifications and installation method documentation for review.

Attic Air Sealing and Comprehensive Documentation

Before cellulose goes into a Chevy Chase attic, our crews seal top plates, plumbing chases, recessed lights, and the attic hatch with foam and gasketing, then install soffit baffles to maintain ventilation pathways. Cellulose is blown to a verified 14 to 16 inches for R-49, with depth markers staked for inspection. Recessed lights receive rated covers or safe clearances, bath fans are confirmed to vent outdoors, and the attic hatch is insulated and weatherstripped. We hold Maryland (MHIC) licensing, pull all required Montgomery County DPS permits, and provide all the documentation needed for Pepco EmPOWER rebates and federal IRS Section 25C tax credits at completion.
