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 Anne Arundel County
A radon test in Annapolis 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 quoted residential service covers one Annapolis dwelling. Provide parking, unit and access details for both waterfront and downtown locations. When street parking or special events could delay access, establish a meeting point and backup contact for each appointment.
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.

EPA places Anne Arundel County in Zone 2. Annapolis owners and buyers need a test in the selected residence for an address-level result.
Annapolis classifies Historic District address ranges as residential, commercial, mixed-use and special historic-commercial zones. Those categories apply within the district and help identify access needs; they do not describe Eastport, Murray Hill or every City property. A downtown apartment can require residential-door, stair and parking instructions that differ from the commercial entrance below. Eastport owners should choose a period without marine-season moves or contractor traffic through the selected room. In Murray Hill, explain current and future use of low rooms. All occupants should know the device must remain untouched until the scheduled collection.

01
The City table distinguishes residential and mixed-use address ranges; book the actual dwelling.
02
Parking, keys and business-hour access should be settled before placement. Share any special-event street closure with the scheduler beforehand.
03
Water proximity is not a substitute for measuring indoor radon in the home.
Where we test in Annapolis, and what to tell us
Historic district and downtown residences
In the Historic District, distinguish an upstairs residence from adjoining commercial space and pause restoration activity.
Eastport-area homes
For Eastport, coordinate occupants and secure a monitor location away from routine entry traffic.
Murray Hill and other residential areas
In Murray Hill and other residential areas, include any lower room planned for regular future use.
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.
Md. Real Property section 10-702. Current as of September 2026. General information, not legal advice.
The residential unit can be tested, but other units or commercial space need separately defined scopes.
No. Test the indoor residence rather than inferring a result from proximity to water.
Keep the selected area accessible, maintain required conditions and leave the monitor untouched.
Complete or pause disruptive work before placement and resume after retrieval.
