4.9 rating, over 4,000 reviews NRSB-certified technicians Serving Anne Arundel County
A radon test in Arnold 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 standard residential price covers one Arnold home or unit. Book online or call with the full address and access contact, especially when a tenant or manager is involved.
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.
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 Arnold.
An Arnold home's radon level cannot be inferred from another Anne Arundel County address or a Maryland map. Testing the house, townhouse or condo you occupy gives a result tied to that residence. Describe the lowest room that is or could be used regularly, including a basement office or guest room planned after a sale. Newer construction and a previous owner's report do not substitute for a current measurement of the home being considered.
For an Arnold radon test, give us the full property address and explain whether the request includes a separate guest unit or just the main residence. Arrange a contact for placement and collection after at least 48 hours. During the measurement, occupants should follow closed-house instructions and leave the monitor undisturbed. If a buyer needs the report by a contract date, provide that date before scheduling so both visits and reporting can be planned.

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.
No. Maryland's map summarizes other measurements. Only testing your residence can provide its indoor radon level.
Yes. The age of a home and any radon-resistant features do not provide a measured result for the finished residence.
Tell us if a separate dwelling also needs testing. The standard appointment covers one residence; additional scope and access should be agreed before the visit.
Give the contract deadline when booking. The schedule must allow for placement, at least 48 hours of measurement, collection and delivery of the report.
