How much does radon testing cost in Takoma Park?

A radon test in Takoma Park 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 residential rate applies to one Takoma Park home or unit. Book online or call with the precise dwelling, entry contact and any additional household requiring scope.

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 Takoma Park homes and rentals

A Takoma Park radon test gives a result for the actual Montgomery County home or private unit, not for the neighborhood as a whole. A county radon map and a nearby home's report cannot measure the booked 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 multifamily property, identify the exact dwelling needing the report.

Provide the complete Takoma Park street address and a person authorized for monitor placement and collection. For a rental or managed building, give the unit number, resident contact and entry instructions for both visits. Occupants should follow closed-house instructions while the device remains undisturbed for at least 48 hours. Schedule repairs or moving outside the test interval and allow time for pickup and the written report before a deadline.

Radon testing guidance: Maryland Department of Health radon guidance, EPA radon-zone map guidance.

Where we test in Takoma Park, and what to tell us

  • Old Takoma and Takoma Junction

    Describe the actual lower-room layout rather than assuming it from building age.

  • Sligo Creek Parkway

    Give the full address and a dependable entry contact for both visits.

  • New Hampshire Avenue

    For a managed unit, identify the private dwelling and resident access.

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 Takoma Park

Radon testing in Takoma Park, answered straight

Does a Montgomery County radon map tell me my Takoma Park home's level?

No. The map describes area potential. Only a measurement inside the particular residence provides its indoor result.

Which lower room matters for a Takoma Park radon test?

Tell the technician about the lowest room used or suitable for regular occupancy, including a room planned for use after purchase. The technician selects the test position under the testing protocol.

What if a Takoma Park property contains several apartments?

Identify the particular unit needing a result. Another unit's reading does not answer for it.

Can movers or repair crews work during the test?

Choose dates that keep the monitor and closed-house conditions undisturbed for at least 48 hours; discuss unavoidable work before booking.
