Home/Radon Testing/Stafford County/Stafford, 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 Stafford County
A radon test in Stafford 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. One quoted residential service covers one Stafford dwelling. Mention a tenant, gate or distant keyholder before booking. Confirm mobile reception or a meeting point when the street address alone may not guide the technician to the correct dwelling.
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.
NRSB-certified technicians. Our own team, certified by the National Radon Safety Board, not a subcontractor.
EPA testing guidance. Placement, closed-house conditions and the 48-hour minimum follow it, and your average is read against the EPA action level of 4.0 pCi/L.
Continuous monitors. Airthings Corentium Pro instruments, logging every hour for the whole test.
Appointment times are requests until our team confirms them. What the number means, how to prepare the property and the eight questions everyone asks are on the radon testing page; this page is about Stafford.
EPA lists Stafford County in Zone 1. This county-level potential supports testing, not a conclusion about a Stafford residence.
A 2019 County profile says Stafford remained mostly rural until Interstate 95 was built in the late 1960s. That county history is not a construction date for a particular home. Stafford service addresses can require careful travel and key coordination between the Courthouse, Aquia, Garrisonville, Brooke Station and Falmouth areas. Confirm directions and the responsible adult for each visit. If the property is vacant, verify normal mechanical operation and secure the device. If occupied, notify residents of the measurement window and retrieval plan. Give the technician a local contact who will remain available if entry conditions change before pickup.

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.
