How much does radon testing cost in Crofton?

A radon test in Crofton 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 home-test rate applies to one Crofton residence. Book online or call with the exact unit and contact details when an association, tenant or gate affects access.

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.

Radon testing for Crofton homes and townhouses

A Crofton house or townhouse needs its own radon measurement. Anne Arundel County data and a neighboring property's report cannot tell you the indoor level of the home you are buying or occupying. Describe the lowest room that could be used regularly, such as a basement bedroom, office or family area. If a townhouse has a separate lower apartment, identify that dwelling before booking so the test is scoped to the right residence.

For a Crofton appointment, give the full address, any unit number and a contact who can provide access on both visits. The monitor stays in place for at least 48 hours. Occupants should follow closed-house instructions and avoid moving it. If the home is vacant, provide a reliable lockbox or agent contact; if occupied, tell residents the schedule. Discuss ongoing work or a contract deadline early enough to plan collection and the written report.

We only perform testing, not mitigation.

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 Crofton, answered straight

Do attached Crofton townhouses need a radon test?

Yes. The fact that a home is attached does not supply its indoor radon level. Test the particular residence for a property-specific result.

What if a townhouse has a separate lower apartment?

Tell us before booking. A standard appointment covers one residence; another dwelling may need its own scope and access.

Can a vacant Crofton home be tested?

Yes, if an authorized contact can provide access for placement and collection and the required conditions can be maintained.

How long does the Crofton test take?

Allow for monitor placement, at least 48 hours of measurement, collection and delivery of the written report. Share a purchase deadline when scheduling.
