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 Manassas Park?

A radon test in Manassas Park 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 rate covers one Manassas Park residence; provide unit and keyholder information. Provide a backup access contact when commuter schedules could prevent the primary resident from meeting the technician at retrieval. Confirm the report recipient when booking.

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 Manassas Park.

Radon testing for Manassas Park homes

Whether you live in a Manassas Park house, townhouse or apartment, a map cannot reveal the radon level indoors. Virginia health officials recommend testing every home, including homes in areas with lower map ratings. The measurement needs to be made in the residence you occupy or are buying. Tell the technician about the lowest room that could be used regularly, such as a lower bedroom, office or playroom.

When booking a Manassas Park radon test, provide the complete street address and unit number, plus someone who can open the property for placement and collection. The monitor remains in place for at least 48 hours. Choose dates when occupants can follow the technician's closed-house instructions and leave the device undisturbed. If you are testing as part of a sale, allow time for the second visit and report before the deadline.

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.
