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 Fairfax Station?

A radon test in Fairfax Station 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. Pricing is for one Fairfax Station residence. A guest dwelling, tenant apartment or other independently occupied structure on the same parcel should be listed separately before the visit.

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 Fairfax Station.

Fairfax Station radon testing: the home's own result

Fairfax Station is in Fairfax County, an EPA radon Zone 1 jurisdiction. The zone signals countywide potential but cannot tell an owner what a particular Fairfax Station home measures. Testing the residence itself is essential, with placement planned around the lowest level that could be used regularly for living, sleeping, work or recreation.

Fairfax County's Pohick plan describes detached houses and townhouses in the district east of Ox Road; it does not describe every Fairfax Station property. A Barrington or South Run address may need clear driveway or gate directions, while a Hampton Chase or Fairfax Station East home may have a lower walkout room. Tell the technician the actual layout and future room use, then arrange reliable entry for the return visit as well as placement.

Railroad tracks running through bare winter woods

Barrington and South Run arrival

Send gate, driveway, alarm and pet instructions that will still work at monitor collection.

Hampton Chase walkouts

A walkout door does not settle placement; explain how the connected lower rooms are or will be used.

Canterberry Estates timing

Schedule around renovations, moving crews or gatherings that could disrupt the test conditions.

Where we test in Fairfax Station, and what to tell us

Barrington, South Run
In Barrington or South Run, give the technician a property contact and practical arrival instructions.
Hampton Chase, Fairfax Station East
For Hampton Chase or Fairfax Station East, identify any lower office, bedroom or recreation space.
Canterberry Estates
At Canterberry Estates, select a calm interval and keep the monitor untouched through pickup.

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 Fairfax Station, answered straight

Where does the Fairfax Station housing fact apply?

The cited Pohick plan describes development east of Ox Road as predominantly detached houses and townhouses. It should not be extended to every Fairfax Station address or used as a property classification.

What access notes help at a long Fairfax Station driveway?

Send turn-by-turn landmarks, gate instructions, alarm steps and an on-site contact. Confirm that the same route will be open when the device is scheduled for retrieval.

How is a Fairfax Station guest dwelling handled?

Identify it separately from the main home and state which residence the client is authorized to test. Occupancy, entry and pricing must be confirmed for the requested dwelling.

What if a contractor opens the lower walkout during collection?

Record when the door was open, how long the activity lasted and whether anyone touched the device. Give those details to the technician rather than changing the monitor yourself.
