Older brick houses

Many Arlington houses are brick colonials, Cape Cods and bungalows from the 1920s to the 1950s. They usually need attic air sealing and depth, knee wall insulation in Cape Cods, and rim joist and basement work.

Additions and teardowns

Arlington sees a lot of additions and rebuilding. When walls and roofs are open, foam is the time-efficient way to seal and insulate.

Virginia's code

Virginia's 2021 Residential Code became effective January 18, 2024. Arlington is in Climate Zone 4A.

Cape Cods and bungalows

Arlington has many small Cape Cods and bungalows from the 1930s and 1940s with finished upstairs rooms under the roof. The knee walls, the small attic spaces behind them, and the sloped ceilings are usually poorly insulated. Foam or dense-pack in those spots is often the fix for an upstairs that is hot in summer and cold in winter.

Basements

Basements in older Arlington houses often have block walls and an exposed rim. Closed-cell foam there is an affordable, noticeable upgrade.
