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 Woodlawn?

A radon test in Woodlawn 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 Woodlawn house, townhouse, apartment or condominium residence. Book online or call with the exact address and identify any additional unit that would need a separate measurement.

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 Woodlawn.

Radon testing for Woodlawn homes and private units

A Woodlawn radon test measures the actual Baltimore County house, townhouse or private unit involved in the decision. The EPA places Baltimore County in Zone 1 for predicted radon potential, but the county map does not provide a reading for any Woodlawn address. Describe the lowest room used or suitable for regular occupancy, including a basement family room, office or bedroom planned after purchase. The technician will select the measurement position under the test protocol. A nearby property's result is not a substitute.

Before booking in Woodlawn, provide the full street address and any building or unit number. Name the owner, resident, agent or manager who can admit the technician for both placement and collection. In a rental, confirm which private dwelling needs the written report; a shared basement or another unit is a different space. Occupants should follow closed-house instructions and leave the monitor undisturbed for at least 48 hours. Schedule repairs, moving and cleaning away from the test room, and mention any sale or lease deadline when requesting dates.

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 Woodlawn, answered straight

Does Baltimore County's Zone 1 label give my Woodlawn home's radon level?

No. Zone 1 describes predicted county potential. Test the particular residence to obtain its indoor result.

Should a Woodlawn basement room be included in test planning?

Yes. Tell the technician about the lowest room used or suitable for regular occupancy, including a room planned for use after purchase. The technician chooses the test location under the protocol.

Can a Woodlawn apartment use another unit's radon report?

Another unit's reading does not establish the level in your private dwelling. Give the building and unit number that needs a result.

How should occupants prepare for the Woodlawn test?

Follow the closed-house instructions, keep the monitor undisturbed for at least 48 hours, and arrange access for both placement and collection.
