4.9 rating, over 4,000 reviews NRSB-certified technicians Serving King George County
A radon test in King George 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 residential rate applies to one King George dwelling. Provide directions, gate details and a reliable contact for both visits. Tell the office about base or workplace entry restrictions; residential testing cannot proceed without permission to enter the selected home.
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.

EPA lists King George County in Zone 3. Elevated homes can occur in any zone, so the selected residence still needs a test.
King George County traces its self-government to 1720 after separation from Richmond County. This civic history does not describe the age, construction or radon level of a present home. King George appointments may involve longer routes, controlled Dahlgren-area entry or a vacant river-area property. Give precise directions and ensure the technician can return for collection. At Fairview Beach, proximity to water is not an indoor-radon indicator. At the Courthouse or Route 3, schedule around occupants who can maintain the required conditions. Arrange a backup contact when travel or secure-site schedules could prevent the primary keyholder from attending.

03
Location near a river does not provide an indoor reading or change the need for testing.
Where we test in King George, and what to tell us
Courthouse and Route 3 area
Near the Courthouse and Route 3, choose dates when occupants can maintain the required test conditions.
Dahlgren-area addresses
For Dahlgren-area housing, identify the precise unit or house and any controlled-entry procedure.
Fairview Beach and river-area properties
At Fairview Beach or river-area properties, do not infer indoor radon from proximity to water; test the residence.
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.
Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.
