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 Baltimore County
A radon test in Towson 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. One residential appointment covers one Towson dwelling. Include apartment number, desk procedure and parking directions for managed buildings. A buyer using a contingency should confirm both appointments early enough to receive the report before the decision deadline.
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.

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 Towson.
EPA identifies Baltimore County as Zone 1. Towson is within the County, unlike independent Baltimore City, and each Towson residence requires its own test.
A County survey records that East Towson was 95 percent improved by 1927 with single-family dwellings, social buildings, a school and religious structures. This is a historical East Towson condition, not a current Towson-wide housing profile. Stoneleigh and Anneslie homeowners can clear a low room and discuss possible future occupancy. At Rodgers Forge, the attached layout does not merge neighboring residences for testing purposes. Downtown apartment residents should identify the unit and building contact. East Towson history remains local context while the technician relies on the present home, its access and its regular-use spaces.
Local background: Maryland Department of Health radon guidance, EPA Map of Radon Zones.
01
The survey describes one district at a historical date and cannot date another Towson home.
02
Attached residences still produce individual test results.
03
Confirm permitted visit times and a contact who can admit the technician twice.
Where we test in Towson, and what to tell us
Stoneleigh and Anneslie
In Stoneleigh or Anneslie, discuss current low-level room use rather than applying East Towson’s 1927 record.
Rodgers Forge area
Around Rodgers Forge, identify the individual attached residence and keep the measurement separate from neighboring homes.
Downtown Towson and managed residences
Downtown Towson residents should arrange elevator, lobby and unit entry for placement and collection.
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.
