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 Stafford?

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

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 Stafford.

Radon testing for Stafford homes

A Stafford County radon map is a broad guide; it cannot answer whether the house you own or plan to buy has elevated radon. Virginia health officials recommend testing every home because high readings can occur across map categories. A test in the actual Stafford residence gives a property-specific result. Let the technician know about the lowest level that could be used regularly, including a planned lower bedroom, office or family room.

For an occupied or vacant Stafford property, arrange a contact who can provide access when the monitor is placed and when it is collected at least 48 hours later. Send the full address and any driveway, gate, alarm or pet instructions. During the measurement, occupants should follow closed-house instructions and leave the device undisturbed. If the home is being sold, choose dates that leave time for both visits and the written report.

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

Detached home with an attached garage and front lawn

Test the booked home

A county label or neighbor's result is not a Stafford property measurement.

Check the lower level

Include a room intended for regular use even if it is empty during the visit.

Plan vacant-home access

A seller or agent must be reachable for placement and collection.

Where we test in Stafford, and what to tell us

Stafford Courthouse area
Provide the property's exact address and any lower room planned for regular use.
Aquia and Garrisonville area
For a sale, arrange an agent or owner who can admit the technician twice.
Brooke Station and Falmouth area
Share arrival details and a reliable pickup contact.

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.

Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.

Radon testing in Stafford, answered straight

Can a Stafford neighbor's radon test stand in for mine?

No. Indoor radon can differ between nearby homes. The useful result comes from testing the specific residence being occupied or purchased.

Which lower space should I mention for a Stafford test?

Describe the lowest room that could be used regularly, including a future bedroom, family room or office. The technician will assess the actual layout and select a suitable test location.

How is a vacant Stafford house tested?

Give the team an owner, agent or keyholder who can open the property for placement and collection. Confirm that the same access method will work at least 48 hours later.

How far ahead should a Stafford buyer book?

Leave time for appointment confirmation, the minimum 48-hour measurement, pickup and the written report. Share the contract deadline before choosing dates.
