Radon risk in Richmond Metro

Richmond is Virginia’s honest-map case: the metro straddles EPA radon zones. West of the fall line — Midlothian, western Henrico, Goochland edges — Piedmont geology raises the odds; toward the coastal plain they drop. Which side of the line your subdivision sits on is invisible from the curb, so Richmond is the region where a $30 test or a professional measurement earns its keep most.

What local houses mean for the fix

Metro Richmond’s stock is a genuine grab bag: brick ranchers on crawlspaces across Henrico and Chesterfield, slab-on-grade starter neighborhoods, and newer basements out toward Midlothian and Mechanicsville. Crawlspace homes get sub-membrane systems; slabs and basements get standard sub-slab suction. Certified pros here quote all three weekly.

Buying or selling here?

Radon tests are a normal line in Richmond-area inspections even in the lower-potential ZIPs — buyers’ agents order them by default. If a mid-transaction result just landed on you, note the closing date in the form and let the responding pros work backward from it.

Start with the numbers: what mitigation costs in Virginia, and if you haven’t confirmed the level yet, how testing works (including the real-estate rules).
