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 Anne Arundel County
A radon test in Severn 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 is for one Severn dwelling. Book online or call with the service address, unit number and person authorized to provide entry.
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 Severn.
EPA classifies Anne Arundel County as Zone 2. The map estimates county-wide potential and cannot produce an indoor reading for a Severn address. Test the selected dwelling and base the decision on that report. The technician evaluates the lowest level that could support regular occupancy, so mention future uses and arrange entry to locked lower rooms.
Anne Arundel County's Region 3 plan says Severn remained a small railroad town into the early twentieth century, with a commercial center near the tracks and a handful of residences. That cultural-resources history is limited to historical Severn and does not describe today's housing stock. A current appointment needs a different set of facts: exact address, defined household, accessible floor plan and responsible keyholder. If the property is vacant, coordinate inspections and maintenance around the deployment. If it is occupied, explain the testing period to everyone who uses the selected area. Do not infer vibration, foundation conditions or radon from proximity to rail history; the monitor inside the residence provides the evidence. A current map may show rail lines or older place references, but those features should not be converted into a theory about air movement or subsurface conditions. Keep directions factual and short. For a property with security procedures, submit gate credentials without placing sensitive access information in public notes. For a household with shift workers, choose a monitor location that can remain protected without disrupting normal occupancy. If an estate representative or relocation company is involved, confirm who has legal authority and who merely receives documents. Clear responsibility reduces missed appointments and preserves an understandable chain of custody. Store the placement and collection confirmations together, including any authorized representative change. A complete administrative trail helps later reviewers connect the result to the correct premises.

01
The County's early-twentieth-century account concerns historical Severn's commercial center and few residences. It is not a description of every modern property.
02
Tell the technician which low rooms are used daily or planned for routine use. Historical land-use patterns do not answer that household question.
03
Name one person responsible for keys, ordinary building operation and protection of the monitor between setup and pickup.
Where we test in Severn, and what to tell us
Jacobs Forest, Piney Orchard
Describe an unfinished or lightly used lower room if it could become regularly occupied. The technician considers the actual Severn residence, not a development-wide floor-plan assumption.
Severn Woods, Disney Estates
Before a sale test, clear reasonable access and tell occupants not to touch, cover or unplug the device. Confirm agent or seller entry for its later collection.
Elmhurst
Arrange a period without furniture moving, repair visits or repeated exterior-door traffic. If circumstances change, preserve the device position and tell the technician what occurred.
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 Region 3 plan provides historical cultural context. The technician measures the current residence and uses its present layout to select the location.
Designate a reliable keyholder for both visits, maintain ordinary building operation, and keep contractors, cleaners and showings from disturbing the monitor.
Arrange authorized access before arrival. The technician may need to evaluate that room if it could be occupied regularly now or after a planned change.
No. Radon can vary among residences, and EPA's zone map is not address-specific. Use a test performed inside the particular dwelling involved in your decision.
