What our customers say

From our customer reviews.

They conducted the test right away and kept me informed every step of the way.

They arrived the day after I called, on time, set up the Radon test and left within 5 minutes.

Everything was handled so professionally, quickly and so easy to have our house tested for radon.

They found elevated radon in the home and numerous issues on the home inspection report which were remedied before I moved in.

Great service, very thorough inspection and highlighted items in a very approachable and organized manner.

How much does radon testing cost in Warrenton?

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

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.

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 Warrenton.

Radon testing for Warrenton homes

A county radon map cannot measure the air inside the Warrenton home you own or plan to buy. Virginia health officials recommend testing homes in every map category because high readings can occur outside areas labeled high risk. The useful result comes from testing the actual residence. Let the technician know which lower room is or could be used regularly, including an office, bedroom or family space planned after a sale.

A Warrenton appointment is for one residence and includes monitor placement, at least 48 hours of measurement and collection. Give us the full address and explain any separate apartment, accessory dwelling or business space before booking so the correct testing scope can be confirmed. Arrange a contact for both visits, follow closed-house instructions and keep renovation or moving activity away from the monitor. A buyer should allow time for the written report before the contract deadline.

Radon testing guidance: Virginia Department of Health radon guidance, Virginia radon risk-map guidance, EPA radon guidance for buyers and sellers.

Detached home with a covered porch and lawn

Measure the home itself

A Fauquier County map category cannot answer for one Warrenton residence.

Clarify separate space

An upstairs apartment or accessory unit may need its own test scope.

Schedule around work

Keep the monitor undisturbed between placement and pickup.

Where we test in Warrenton, and what to tell us

Old Town and Main Street
For a mixed-use building, identify the private dwelling and its entrance.
Oliver City and nearby streets
Describe any lower room planned for regular use.
Warrenton-area accessory dwellings
Tell us if a second living unit also needs a 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 Warrenton, answered straight

Does an Old Town Warrenton home use a different radon test?

The property's age or historic setting does not replace an indoor measurement. Tell the technician about the current living space and lower rooms so placement can follow the testing protocol.

Can a shop and an upstairs apartment share one result?

A standard home appointment measures the booked residence. Identify the apartment and its entrance, and discuss any separate business or living space before scheduling.

Does an accessory dwelling need its own booking?

Tell us if a guesthouse or separately occupied unit also needs a result. Its testing scope, access and price should be confirmed before the appointment.

Should renovation continue during the test?

Avoid work that could disturb the monitor or change the required conditions. If work cannot be paused, tell the testing team before placement so it can assess the schedule.
