How much does radon testing cost in Chevy Chase?

A radon test in Chevy Chase 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 covers one Chevy Chase residence. Book online or call with the full address, correct local entity, unit and access contact.

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 Chevy Chase homes and condos

A Chevy Chase homeowner or buyer should test the residence in question, whether it is a detached house, townhouse or condo. A Montgomery County map and another home's result cannot determine the radon level inside a particular dwelling. Tell the technician about the lowest room that could be used regularly, such as a basement bedroom or office. In a condo, provide the exact building and unit so the test measures the private residence rather than a common area.

For a Chevy Chase test, arrange an authorized contact for monitor placement and collection after at least 48 hours. Provide any concierge, elevator or lockbox instructions that must work on both days. Residents should follow closed-house conditions and leave the device undisturbed. If a renovation is underway or a buyer has a contract deadline, discuss timing before booking so the tested space is ready and the written report can arrive in time.

Where we test in Chevy Chase, and what to tell us

  • Chevy Chase Village and Town of Chevy Chase

    For a house, describe its lower rooms and their planned use.

  • Section Three, Section Five and Martin's Additions

    Coordinate occupants and any active work before placement.

  • North Chevy Chase and nearby condos

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 Chevy Chase

Radon testing in Chevy Chase, answered straight

Can a Chevy Chase map tell me my home's radon level?

No. The map summarizes area results. Only a measurement inside the particular house or condo provides its indoor reading.

Should I test a basement office I plan to use?

Tell the technician about the planned regular use. A lower room suitable for occupancy can affect where the monitor belongs.

How do I arrange testing in a Chevy Chase condo?

Provide the building and unit number, authorized entry contact, and desk or elevator instructions for both placement and collection.

Should renovation continue during the test?

Avoid work that could disturb the monitor or required closed-house conditions. Discuss ongoing work before scheduling the measurement.
