Radon testing
A continuous monitor on the lowest level that could be used regularly, read every hour for at least 48 hours. The written result comes the day we collect it.
4.9 rating, over 4,000 reviews NRSB-certified technicians Serving Charles County
A radon test in Waldorf 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. One Waldorf dwelling is covered; identify any separate apartment before booking.
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.

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 Waldorf.
Charles County is EPA Zone 2; test the Waldorf residence for its own result.
County history traces Waldorf’s development to an 1872 railroad station in a farming community. That date describes community history, not a home. St. Charles, Westlake and Smallwood Drive appointments should identify the exact dwelling, its access contact and the lowest room that could be used regularly. A buyer in St. Charles can ask the agent to identify the lowest potentially regular-use room before placement and confirm who will return for collection. A Westlake tenant should secure management permission and tell household members why the equipment must remain untouched. Along Smallwood Drive, a residence above or beside commercial space needs its own entrance and unit stated clearly. If a seller is moving, deploy the monitor after hauling and repeated exterior-door traffic end. Record any unexpected open window, service visit or loss of normal mechanical operation instead of adjusting the device. The technician can then assess the event at retrieval. These steps protect the measurement without assuming that community age, road location or dwelling style predicts the result.

01
The 1872 station history does not assign an age to a residence.
02
Provide gate, desk and unit instructions before placement. Share the pickup date with management.
03
A second living unit needs its own confirmed scope.
Where we test in Waldorf, and what to tell us
St. Charles and Westlake
At St. Charles or Westlake, arrange association or tenant entry twice.
Smallwood Drive corridor
Along Smallwood Drive, distinguish a residential unit from nearby business space.
Other Waldorf-area residential addresses
At other Waldorf addresses, keep moving and repairs outside the test.
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.
