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 Essex 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 covers one Essex dwelling. Book online or call with the exact unit, access authority and any additional household needing a separately confirmed 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.

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 Essex.
EPA places Baltimore County in Zone 1. The designation forecasts county potential and cannot supply the indoor concentration for an Essex property. Measure the selected residence and use that result for the decision. Describe lower rooms according to current and possible regular occupancy, and keep any separate unit clearly outside or inside the agreed scope.
Baltimore County's legislative index identifies Essex as a designated revitalization district. That district identity was checked September 10, 2026 and does not imply that a particular project occurred, that a building was renovated, or that any indoor condition exists. Ask property-level questions instead. Is the home occupied, vacant or under active work? Who holds the key? Which rooms belong to the household? Will contractors, deliveries or inspections interrupt the measurement? In a managed unit, note desk or gate procedures. In a house with another living area, identify its occupant and entrance. These answers support a workable appointment without turning public policy into a physical claim. Revitalization legislation can change over time and can cover public or private initiatives unrelated to the booked residence. The durable homeowner guidance is simpler: verify the premises, disclose active work, identify regularly occupied low rooms and protect the instrument. If grants, permits or rehabilitation paperwork exist, review them for their own purposes rather than treating them as a radon report. At a rental, send preparation directions to both owner and occupant. At a condominium, ask management only for access information. A focused request keeps policy history from overshadowing the actual Essex household decision. If planned rehabilitation is only proposed, describe it as future work. Do not write as though funding, construction or completion has occurred at the address without supporting property records.

01
The County designation establishes a policy district. It does not show that an Essex home received improvements or has a particular age, layout or radon level.
02
Painting, demolition, flooring and repeated door use can disrupt access or conditions. Coordinate a settled interval and report any unexpected work.
03
For a vacant or managed property, identify a responsible person for setup and retrieval rather than relying on several uncoordinated contacts.
Where we test in Essex, and what to tell us
Aero Acres
For a managed or attached residence, record the unit and authorized contact. Make both visits possible without granting access to unrelated apartments or shared facilities.
Back River Highlands, Middleborough
A geographic name does not predict a reading. Show the technician the dwelling's own low rooms and mention any future use that could make an unfinished space regularly occupied.
Fox Ridge Manor, Norwood
If a renovation is planned, select dates before work begins or after normal operation resumes. Keep crews, materials and ventilation changes 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 County designation identifies a policy area and does not document work at an individual address. Verify improvements separately and test the residence for radon.
Schedule it outside disruptive work that changes ventilation, increases exterior-door traffic or could move the device. Wait for ordinary operation when those conditions cannot be maintained.
Provide the exact unit, authorized keys, ordinary building-operation plan and a dependable contact for placement and retrieval. Limit other entries while the monitor is deployed.
Yes, when it could be used regularly after finishing or reconfiguration. Describe the intended use so the technician can evaluate the correct measurement level.
