What kind of homes and basements does Arlington have?

Neighborhoods such as Lyon Park, Westover and Cherrydale are dominated by 1920s to 1950s brick colonials, bungalows and garden apartments with block or brick basements. Newer infill homes often have deep poured basements, many finished. Some soils in Northern Virginia contain shrink-swell marine clays.

What causes basement and foundation problems in Arlington?

Walkout and window-well leaks

Sloped lots channel stormwater into window wells and against the uphill wall, especially during summer thunderstorms.

Shrink-swell clay movement

Marine clays in parts of Northern Virginia swell when wet and shrink when dry, which can crack walls and slabs over time.

Finished-basement mold

Water entering behind drywall in finished basements leads to hidden mold; addressing drainage before finishing is key.

What license should an Arlington basement contractor have?

Virginia requires a Board for Contractors license from the Department of Professional and Occupational Regulation, in a class matching the job value. Arlington County also issues building permits for structural and excavation work.

Why do window wells flood in Arlington?

Window wells collect rain and runoff on sloped lots. If the well drain is clogged or missing, water rises and leaks through the window. A drain tied to the footing drain and a cover usually fix it.
