What our customers say

From our customer reviews.

Great work! Radon test was smooth and we got our results back on the same day. Highly recommend!

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.

How much does radon testing cost in Perry Hall?

A radon test in Perry Hall 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 listed service price covers one Perry Hall residence. Another apartment, accessory dwelling or shared community room is outside that booking until authorization and pricing are reviewed.

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 Perry Hall.

Radon testing for Perry Hall homes and townhouses

A Baltimore County radon-zone label does not measure a Perry Hall residence. A test in the actual house, townhouse or apartment gives an owner or buyer the relevant result. Tell the technician about the lowest room used or suitable for regular occupancy, including a basement bedroom, office or recreation room planned after a sale. If a building has more than one dwelling, identify the booked unit rather than relying on a nearby or shared-area reading.

Provide the full Perry Hall address, unit number if applicable, and an entry contact for both monitor placement and collection. The device remains undisturbed for at least 48 hours while residents follow closed-house instructions. If a tenant, manager or listing agent holds the keys, coordinate both visits in advance. Keep pets and household work away from the test room, and share any transaction deadline before choosing 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 Perry Hall, answered straight

Can a nearby Perry Hall result replace my test?

No. Test the particular residence needing the report; a neighbor's reading cannot establish its indoor level.

What if a basement will become a bedroom?

Tell the technician about that planned regular use before placement.

How do I arrange entry to a managed unit?

Give the building, private unit and authorized contact, with instructions for placement and collection.

What if a pet disturbs the monitor?

Tell the testing team promptly. Movement or interference may affect whether the measurement can be used.
