Spray Foam Insulation in Silver Spring, MD

Spray foam insulation in Silver Spring covers a large, varied housing stock. The B&O Railroad's Metropolitan Branch opened through Silver Spring in 1873, and suburban development picked up in the 20th century, including Woodside Park, laid out in 1922. By the 1950s Silver Spring was a major retail center. The 2020 census counted 35,150 housing units in the CDP, 5.0 percent vacant.

What we see

Brick and frame colonials, Cape Cods and ramblers from the 1920s through the 1960s, with walk-up or hatch attics, basements and often a crawl space under a later addition. Typical needs: attic air sealing and depth, rim joist foam, and crawl space work.

Maryland's code

Maryland adopted the 2021 IECC effective May 29, 2023, with R-49 ceilings in Climate Zone 4. Montgomery County is in Zone 4A. ENERGY STAR suggests R-60 for an uninsulated Zone 4A attic.

Humid summers

Basements and crawl spaces in Silver Spring can get damp in summer. Encapsulation and closed-cell foam help, once any water entry is fixed.

Splitting the work into phases

Many Silver Spring owners tackle the attic one year and the basement the next. Because we quote each area separately, it is easy to phase. Air sealing the attic and topping up insulation is usually the place to start, since it helps both summer and winter.

Sligo Creek and slopes

Houses near creeks and on slopes can have walkout basements with tall exposed foundation walls, good candidates for closed-cell foam. Get a free estimate
