Spray Foam Insulation in Alexandria, VA

Spray foam insulation in Alexandria spans centuries of housing. The city was established in 1749 and incorporated as a town in 1779, and its Old Town has townhouses from the port's early decades. In 1930 Alexandria roughly doubled in size by annexing land from Fairfax and Arlington counties, adding neighborhoods that filled in during the New Deal, World War II and postwar years.

Old Town

Part of Old Town's core was designated historic in 1946. Townhouses here have masonry walls, old attics and basements close to the river. As in Georgetown, start with the roof and basement, and plan any exterior change with the historic review process.

1930s-1960s neighborhoods

Brick colonials and Cape Cods west of Old Town usually need attic air sealing and depth, knee walls, and rim joist foam.

Low ground near the river

Waterfront and low areas can have damp basements. Water first, then insulation.

Postwar garden apartments and townhouses

Alexandria grew quickly with federal employment during the New Deal and World War II. Townhouses and smaller homes from that era usually benefit from attic air sealing and topping up, rim joist foam, and sealing around old chimneys and plumbing chases.
