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 Essex?

A radon test in Essex 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 rate covers one Essex dwelling. Book online or call with the exact unit, access authority and any additional household needing a separately confirmed scope.

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 Essex.

Radon testing for Essex homes and townhouses

An Essex homeowner or buyer needs a reading from the specific residence, not a Baltimore County average or another property's report. A detached house, attached townhouse and condo each have to be identified by their own address or unit. Tell the technician about the lowest room that is or could be used regularly, including a basement office, bedroom or family area. This matters even when the room's use will change after a purchase.

For an Essex radon appointment, provide the complete address, unit number if there is one, and a contact for both monitor placement and collection. The device stays undisturbed for at least 48 hours while residents follow closed-house instructions. If a townhouse has a separate rental unit or a condo building controls entry, discuss those details before booking. A buyer should also share the contract deadline so there is time for the written report.

Where we test in Essex, and what to tell us

Aero Acres
For a house, identify the lowest room used or planned for regular use.
Back River Highlands and Middleborough
For an attached home, clarify the booked unit and entry contact.
Fox Ridge Manor and Norwood
Coordinate occupants and avoid repairs near the monitor.

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 Maryland

Maryland's residential disclosure framework includes radon among the hazardous or regulated materials covered by an owner's actual knowledge for certain single-family residential property of four or fewer units. The statute has enumerated exemptions and does not itself require a radon test. County and municipal requirements may differ, so check the rules for the property's location and type before relying on an existing result.

Radon testing in Essex, answered straight

Can another Essex home's radon result answer for mine?

No. Indoor levels can differ between homes. Test the Essex residence you occupy or plan to buy for its own reading.

Should a townhouse basement be included?

Tell the technician if the lower room is or could be used regularly. The actual layout and intended use guide placement under the protocol.

Can one Essex appointment cover a separate rental unit?

A standard home appointment covers one dwelling. Identify every separate unit needing a result so scope, access and price can be confirmed.

How should occupants prepare?

Arrange access for both visits, follow the closed-house instructions and keep the monitor undisturbed for at least 48 hours.
