Most of the DMV is EPA Zone 1 — the highest radon risk classification. Biennial certified testing, mitigation verification, and disclosure-ready records.
EPA-recommended retest every 2 years for occupied homes. Continuous monitor placement with chain-of-custody documentation suitable for real estate disclosure.
If you have an active radon mitigation system, annual manometer and fan operation verification. Failed fans are silent and the system runs for years pretending to work.
If your home tests above 4.0 pCi/L, we coordinate licensed mitigation contractors, evaluate bids, and oversee installation as your owner's representative.
Every test logged with timestamp, location, conditions, and result in your Digital Home Twin — ready to hand to a buyer's agent at sale.
