Home/Radon Testing/Fauquier County/Warrenton, VA
Radon testing
A continuous monitor on the lowest level that could be used regularly, read every hour for at least 48 hours. The written result comes the day we collect it.
4.9 rating, over 4,000 reviews NRSB-certified technicians Serving Fauquier County
A radon test in Warrenton is $185, or $175 when it is added to a home inspection. That is the whole price: both visits, the monitor for the full 48 hours, and the written report with every hourly reading in it. The listed service covers one Warrenton residence. Call if an accessory dwelling or mixed-use building creates more than one unit. If the property contains both a main house and rented cottage, identify which residence the appointment covers. Name the keyholder for both visits.
Day 1
Drop-off
A technician places it on the lowest level that could be used regularly, following EPA placement limits and the intended use of the space, inside a two-hour arrival window. With a home inspection, placement happens during the inspection visit.
48 hours
The house stays closed
For a short-term real-estate test, EPA guidance calls for closed-building conditions for at least 12 hours before the test and throughout the measurement. Windows stay closed, exterior doors open only for normal entry and exit, and the monitor logs hourly readings that help document the test conditions during the minimum 48-hour measurement.
Day 3
Pick-up and report
A technician picks the monitor up in another two-hour window and pulls the full record on the spot. The written report reaches you the same day.

Fauquier County is EPA Zone 2. That category does not supply the radon level for a Warrenton home, so an address-specific test is needed.
Warrenton says its Historic District contains a central business district and five surrounding residential neighborhoods. The fact applies to the district only. Old Town buildings can combine residential and commercial access, and an accessory structure may contain a separate dwelling. State exactly which home needs the result. In Oliver City and other established streets, choose the lowest regularly usable area from the current layout. Keep repairs, deliveries and tenant turnovers outside the monitoring interval.

Where we test in Warrenton, and what to tell us
Old Town and Main Street residential edges

We do not install radon systems, so we have nothing to gain from your number. If the result is at or above the EPA action level of 4.0 pCi/L, you choose who fixes it. Once the system is in, we can test again and tell you what it reads.
Virginia's residential disclosure statute directs the seller's disclosure statement to say that the owner makes no representation about whether the property is in an EPA Zone 1 or Zone 2 locality. It directs buyers to use due diligence, including reviewing EPA, Virginia Department of Health and NRSB information and ordering a radon inspection before settlement as the contract allows.
