A radon test in Elkridge 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 residential rate covers one Elkridge dwelling. Book online or call with the full address, unit designation and access arrangements if an agent, tenant or manager controls 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.

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 Elkridge.
An Elkridge address or Howard County map cannot reveal the radon level in one home. A test of the actual house, townhouse or condo gives the owner or buyer a property-specific result. Tell the technician about the lowest room that could be used regularly, including a basement bedroom or office planned after the sale. For a condo, identify the private unit rather than relying on another unit's reading or a common-area result.
Before booking an Elkridge radon test, provide the full address, building and unit number if applicable, and a contact who can admit the technician twice. The monitor stays in place for at least 48 hours. Residents should follow closed-house instructions and leave it undisturbed. If a building has a front desk, key system or elevator restrictions, confirm access for both placement and pickup. Mention repairs or a contract deadline when choosing dates.

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. Another unit's result does not measure yours. Provide the exact building and unit so the requested residence can be tested.
Tell the technician how the room is or will be used. A lower space suitable for regular use can affect the placement location.
The technician needs authorized entry to the private unit for placement and again after the minimum 48-hour measurement. Share desk, key and elevator rules in advance.
Avoid work that could disturb the monitor or closed-house conditions. Discuss unavoidable repairs before booking so suitable dates can be chosen.
