Commercial Radon Testing for Multifamily, Healthcare, School and Institutional Properties
RADON & CO provides professional commercial radon testing for multifamily properties, nursing homes, assisted living facilities, schools, childcare centers, offices, rental portfolios, healthcare facilities, and institutional buildings across Maryland, Washington DC, and Northern Virginia.
Commercial testing is a project, not a single appointment
Larger buildings may require multiple test locations, coordination with maintenance or administrative staff, access planning, device tracking, reporting needs, and documentation for owners, lenders, consultants, facility teams, or property records.
How commercial test locations get determined
A single-family home usually needs one monitor, on the lowest livable level. A commercial building rarely works that way: a large ground-contact footprint, multiple HVAC zones, and different occupancy types under one roof mean the number and placement of test locations has to be worked out from the building's actual layout, not assumed from square footage alone. In general, priority goes to occupied rooms in ground contact with the soil — basements, slab-on-grade wings, below-grade offices or classrooms — since that's where radon entry risk concentrates, with additional locations added as the building's zoning and floor plan warrant. Montgomery County's EPA Radon Zone 1 designation (predicted average indoor screening level above 4 pCi/L) applies to commercial buildings here just as much as homes, so local commercial properties aren't a lower-priority category by geography — if anything, the same regional risk that makes residential testing worthwhile here applies to office buildings, schools, and healthcare facilities in the same soil.

Most short-term professional radon tests run for at least 48 hours. RADON & CO places a digital continuous radon monitor, retrieves it after the test window, and provides a clear electronic report.
How much does residential radon testing cost?
Residential radon testing in Montgomery County is $125. Washington DC, Northern Virginia, Howard County, and select surrounding areas typically start at $125 depending on distance, access, and scheduling.
Do you test for real estate transactions?

Do you test commercial properties?
Yes. RADON & CO supports commercial radon testing for multifamily buildings, nursing homes, assisted living facilities, schools, childcare centers, property portfolios, and HUD-related projects.
Do you provide mitigation?

To avoid conflicts of interest, NRPP-certified radon measurement professionals are not permitted to perform mitigation on properties they test.
