What our customers say

From our Google reviews.

The whole experience was amazing! Everything was handled so professionally, quickly and so easy to have our house tested for radon.

Was professional and friendly and provided us with immediate information about our radon test. I would highly recommend this company.

How much does radon testing cost in Springfield?

A radon test in Springfield 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 residential price covers one Springfield home or unit. Book online or call with the exact address, unit and access contact when the property is attached, rented or managed.

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 Springfield.

Radon testing for Springfield homes

Springfield homes can have very different lower-level layouts, from a split-level family room to a townhouse basement. Fairfax County's radon map cannot tell you the level inside any one of them, and the county reports that results may vary even on the same street. A test at the property is the useful evidence. Describe the lowest room that could be used regularly, including one planned for work, sleep or family use after a sale.

The technician places a monitor, leaves it for at least 48 hours and returns to collect it. For a Springfield test, provide the full property address, a contact for both visits and any lockbox, alarm or pet details. Everyone with access should follow closed-house instructions and leave the monitor in place. If a contractor is working in the lower level, discuss the schedule before placement so the measurement area can remain undisturbed.

Radon testing guidance: Fairfax County Health Department radon guidance, Virginia radon risk-map guidance, EPA radon guidance for buyers and sellers, EPA guidance on when to retest.

Split-level floor plans

Tell the technician how the lower rooms are used rather than choosing a spot from a map.

Townhouse basements

Include a lower room that may be finished or used regularly after purchase.

Reliable access

Plan for both placement and pickup during the minimum 48-hour test.

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 Springfield, answered straight

Where is a radon monitor placed in a Springfield split-level home?

Tell the technician which lower rooms are or could be used regularly. The technician will review the floor plan and select a suitable location under the testing protocol.

Can a Springfield townhouse basement be included?

Yes, if the lower space could be used regularly. Describe its current condition and planned use before the visit so the technician can assess placement in the booked dwelling.

Should Springfield contractors work near the monitor?

Avoid scheduling work that could disturb the device or change the test conditions. If work cannot be postponed, tell the testing team before placement so it can assess timing.

What does a seller need to arrange for pickup?

Provide a keyholder or authorized entry method for the return visit after at least 48 hours. Leave enough time for collection and the written report before any transaction deadline.
