Arlington conditions

What basement projects in Arlington actually take

In Arlington, the humid Mid-Atlantic seasons drive frost depth and water movement, so waterproofing and a working drain plane come before any framing. Radon is common across this region, so radon-resistant detailing and a sealed sub-slab system are scoped in from the start, in place before the test is ever run. Code-compliant egress and ceiling height are checked first, since they decide whether the space can legally count as living area in Arlington.

Our standard

What we require from basement finishing firms in Arlington
