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
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.

EPA assigns Montgomery County to Zone 1. The map forecasts county potential and does not predict radon in a Takoma Park address. Measure the residence itself. Describe the lowest level that could support regular activity, including an unfinished or currently unused room planned for occupation, and let the technician select a compliant location.
The City says the National Register Takoma Park district includes much of the original residential development and varied late-nineteenth- and early-twentieth-century architectural styles. The City history page was checked September 9, 2026, and its statement is district context rather than an age claim for an individual home. Do not choose a protocol from exterior style. Confirm the present interior, unit boundary and access. In a rental, coordinate owner permission and tenant notice. In a divided or attached property, identify which household needs the report. Schedule preservation work, moving and contractor visits outside the measurement period. The current residence, not the district narrative, supplies the conditions the technician evaluates.

01
The historical styles belong to the National Register district context. They do not date every Takoma Park residence or predict an indoor concentration.
02
Identify the exact dwelling and rooms in scope. A result from one apartment should not be assigned to another household in the same structure.
03
Schedule disruptive repair or restoration outside the measurement period so access, ventilation and equipment position remain stable.
Where we test in Takoma Park, and what to tell us
Old Takoma and Takoma Junction
Historic-district context does not establish the subject home age or radon. Show the technician the current rooms and identify any separate occupancy at the address.
Sligo Creek Parkway
Creek proximity is not an indoor-air measurement. Provide parking or route instructions if useful, then rely on the home device result.
New Hampshire Avenue
For an attached or rented residence, confirm the unit and authorized entry for both visits. Keep moving, repair and repeated door traffic away from the testing interval.
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. The City documents varied historic styles, but exterior design does not predict an indoor reading or replace the standard placement requirements.
Identify the exact household, unit and authorized rooms. Tell NextDay Inspect if more than one residence needs a result so each scope can be confirmed.
Schedule disruptive work at another time. Activity that alters ventilation, increases exterior-door use or risks moving the equipment can compromise the agreed conditions.
No. Geographic proximity is not a property measurement. Use a properly conducted test inside the Takoma Park residence for the decision.
