Radon testing
A continuous monitor on the lowest level that could be used regularly, read every hour for at least 48 hours. The written result comes the day we collect it.
4.9 rating, over 4,000 reviews NRSB-certified technicians Serving Frederick County
A radon test in Brunswick 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 rate covers one Brunswick residence. Book online or call with the exact address, unit and entry arrangements, and identify additional dwellings that need separate 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.
NRSB-certified technicians. Our own team, certified by the National Radon Safety Board, not a subcontractor.
EPA testing guidance. Placement, closed-house conditions and the 48-hour minimum follow it, and your average is read against the EPA action level of 4.0 pCi/L.
Continuous monitors. Airthings Corentium Pro instruments, logging every hour for the whole test.
Appointment times are requests until our team confirms them. What the number means, how to prepare the property and the eight questions everyone asks are on the radon testing page; this page is about Brunswick.
Frederick County is in EPA Zone 1, the highest category for radon potential. The map cannot tell you the level in a specific home; only a test at that address can.
Brunswick homes vary, including those in the Historic District. Tell us about lower-level rooms, locked spaces, and any separate living unit so we can plan the visit around your home's current layout.
Local background: Brunswick National Register Historic District nomination hosted by the City, Maryland Department of Health radon guidance, EPA Map of Radon Zones.
01
The National Register document notes differences in lot, setback and house size. That variety reinforces the need to review the actual residence rather than assume one district-wide layout.
02
A district's age and railroad history provide cultural context only. Neither supplies an indoor concentration or replaces testing at the address.
03
When one property includes another dwelling, state whether that unit also needs testing. Authorization and placement must be clear for each residence.
Where we test in Brunswick, and what to tell us
Historic Downtown Brunswick
The nomination documents varied houses within the district, so do not treat a historic label as a standard floor plan. Show the technician the individual residence's accessible, potentially occupied lower spaces.
Rosemont
Provide the full address and explain who can admit the technician for placement and retrieval. A neighborhood name or nearby result cannot substitute for a measurement in the booked home.
Brunswick Crossing
For an attached home or a property with a separate living unit, define which residence needs the report. Mention a lower room planned for future use and keep the selected area undisturbed.
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 nomination describes the district's history and varied houses. An indoor test at the individual Brunswick property is required to learn its radon level.
The City's National Register document notes that district houses vary. The technician needs the present arrangement and potential room uses to identify the correct measurement level.
Do not assume it can. A separate dwelling may need its own scope, authorized entry and measurement location, so identify both units when requesting service.
Arrange access and explain whether the room could be occupied regularly in the future. The technician needs that information to decide whether the level should be included in placement planning.
