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 Fauquier County?

A radon test in Fauquier 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 standard quote applies to one residence. A second dwelling, tenant space or multi-address request needs its scope and price confirmed.

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.

What the ground does under Fauquier County homes

EPA's raw county table lists Fauquier County as Zone 2. The map estimates area potential and does not establish a concentration for a Warrenton property or another County address. A monitor inside the individual residence supplies the result to use.

A Fauquier County request should identify the dwelling, its lowest level that could be used regularly and anyone needed for entry. Warrenton is the linked local community. If the property includes a second dwelling or several units, list them so the team can confirm a broader scope and price. Warrenton's five residential historic-district neighborhoods provide town context rather than a countywide housing pattern.

01

Fauquier's Zone 2 category is a screening estimate

EPA's County row is background for planning a measurement, not evidence of the value inside a Warrenton or rural County home.

02

Define every living space on the property

A primary residence, guest dwelling and tenant space should be identified separately before the equipment plan and price are confirmed.

03

Choose dates the household can support

Allow 12 hours of closed conditions before placement and a full 48-hour run without planned ventilation changes or prolonged open doors.

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 Fauquier County, answered straight

Does Fauquier County's Zone 2 designation predict my reading?

No. EPA says zone maps are screening tools and are not designed to predict individual homes. The result measured inside the property is the relevant value.

What details should a Fauquier buyer provide before placement?

Give the Warrenton or other county address, contract deadline, lowest level that could be used regularly and the person who can open the residence. Mention any second dwelling or tenant space. Those facts help the team confirm timing, access and scope.

How do I describe a Fauquier property with more than one dwelling?

State which residences need measurement and whether they are in separate buildings. Scope and pricing should be confirmed before the appointment.

How are closed conditions handled for a Fauquier County test?

Begin closed conditions 12 hours before placement and maintain them through the 48-hour run. Windows stay shut, exterior doors are used only for normal entry and exit, and the monitor remains undisturbed.
