4.9 rating, over 4,000 reviews NRSB-certified technicians Serving Prince George's County
A radon test in Fort Washington 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 is for one Fort Washington dwelling. Call with the full address, gate details and any separate living unit so the correct scope can be set before travel.
Day 1
Drop-off
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
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
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.

Prince George's County radon data cannot predict the indoor level of a Fort Washington home. A test of the particular residence gives a buyer or owner the useful result. Tell the technician about the lowest room used or suitable for regular occupancy, including a basement office, bedroom or family room planned after a sale. If a property includes a guest suite or separate dwelling, identify which living space needs a measurement.
Before a Fort Washington appointment, provide the full address, driveway or gate details, alarm and pet instructions, and an authorized contact for both visits. The monitor remains in place for at least 48 hours while occupants follow closed-house instructions. Schedule cleaning, repairs or moving so the device stays undisturbed. Share a contract deadline early enough for collection and the written report, and discuss an additional dwelling before booking.

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.
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.

Tell the technician about the planned regular use. A lower room suitable for occupancy can affect test placement.
