How much does radon testing cost in King George County?
A radon test in King George County 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 price is for one residence. Additional dwellings, rental units or buildings may need more equipment and a confirmed quote.
Day 1
Drop-off
We place the monitor
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
The monitor does the work
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
We collect it, read it, and write it up
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.

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 King George County.
What the ground does under King George County homes
EPA places King George County in Zone 3, its lower estimated potential category. Elevated homes can occur in every zone, so the label is not a clearance. The selected house needs an indoor measurement for a usable answer.
King George is the local community linked from this county page. Plan the appointment around the specific residence, its lowest level that could be used regularly and the person who can provide entry. List any additional dwelling or unit so its scope can be confirmed. King George became a self-governing county in 1720; the testing plan still begins with the present-day residence.
King George's lower estimated category can be misread as a clearance. EPA reports elevated homes in every zone, so a buyer or resident should rely on indoor data from the selected house.
02
County history does not predict indoor air
King George County dates its self-government to 1720. That identity fact supplies local context while the home measurement supplies the radon result.
03
Maintain ordinary, stable indoor operation
Keep windows closed, avoid extended exterior-door opening and tell the technician before making ventilation changes during the measurement.
We only perform testing, not mitigation.
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.
Before you book in Virginia
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.
Radon testing in King George County, answered straight
What does the EPA map establish for King George County?
It is EPA's lower county-potential classification, not a promise about one address. The only home-specific value comes from measuring the King George residence.
What should be ready before a King George monitor is placed?
Confirm entry, identify the lowest level that could be used regularly and begin closed conditions 12 hours before setup. Tell occupants not to move or unplug the device during the 48-hour run and to report any unusual event.
Which level matters for a King George County measurement?
Show the technician the lowest part of the dwelling that could be used regularly. Current finishes alone do not settle the choice; intended occupancy and the room's relationship to the residence also matter.
When is the King George written radon result delivered?
The continuous monitor runs for 48 hours. After collection, the written result is delivered that day with the measurement record for the residence.
