How much does radon testing cost in Odenton?

A radon test in Odenton 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 home-test rate applies to one Odenton dwelling. Book online or call to define additional units, controlled entry or a multi-residence request.

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 Odenton houses, townhouses and apartments

An Odenton radon test should be planned for the particular home or apartment needing a result. Anne Arundel County's map and another unit's report cannot establish the indoor level of your residence. Tell the technician about the lowest room used or suitable for regular occupancy, including a basement bedroom or office planned after purchase. In a building with shops, shared rooms or multiple dwellings, identify the private residential unit being tested.

Give the full Odenton address, building and unit number if applicable, and a contact authorized to admit the technician for placement and collection. The monitor remains undisturbed for at least 48 hours while occupants follow closed-house instructions. A tenant, building manager or agent may need to coordinate both visits. Schedule moving or repair work outside the measurement period and share a purchase deadline early enough for the written report.

  • Chapel Grove

    Coordinate the owner or agent for two visits.

  • Four Seasons Estates and Kings Heights

We only perform testing, not mitigation.

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.

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 near Odenton

Radon testing in Odenton, answered straight

Can an Odenton neighbor's result cover my home?

No. Indoor levels can differ. Test the specific house or unit that needs the report.

What if the building has shops or shared rooms?

Identify the private residence and its entrance; another space's reading does not replace a test in that dwelling.

How should a buyer plan the schedule?

Allow time for placement, at least 48 hours of measurement, collection and the written report before the deadline.

Can I move the monitor for a showing?

No. Leave it in place and tell the testing team if it is disturbed; moving it can affect the measurement.
