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 Stephens City?

A radon test in Stephens City 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 home-test rate covers one Stephens City residence. Book online or call with the exact address and any separate-unit details.

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.

Radon testing for Stephens City homes

A regional radon map cannot tell a Stephens City buyer or homeowner what is in the air inside one residence. Virginia health officials advise testing homes in every map category. The measurement should be made in the actual house, townhouse or apartment being occupied or purchased. Tell the technician about the lowest room that could be used regularly, even if the next owner plans to finish or occupy it later.

A Stephens City radon appointment covers one residence and requires access for monitor placement and collection after at least 48 hours. Provide the complete address and unit number when applicable, plus a person who can open the property on both visits. If a building contains a separate rental or accessory unit, mention it before booking so the testing scope can be clarified. Keep the selected room accessible, follow closed-house instructions and avoid disturbing the monitor.

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

We only perform testing, not mitigation.

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 Stephens City, answered straight

Does a radon map predict a Stephens City home's result?

No. The map describes broad potential and cannot measure indoor air at a specific address. Test the home itself for a property-specific result.

Can two apartments at one Stephens City address share one test?

A standard appointment measures one residence. Identify the exact unit, and tell us if another apartment or accessory dwelling also needs testing so access and scope can be discussed.

What room should be considered for testing?

Tell the technician about the lowest level that could be used regularly, including a room a buyer intends to finish or occupy. The technician selects a suitable location after reviewing the layout.

How should I prepare for the 48-hour period?

Arrange access for placement and pickup, follow the technician's closed-house instructions and keep occupants or workers from moving the monitor.
