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 Loudoun County
A radon test in Lansdowne 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 Lansdowne residence is covered by the normal price. Another unit, club facility, guest residence or separately occupied suite requires its own approved 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.
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 Lansdowne.
Virginia Department of Health corrects the older EPA map by identifying Loudoun County as high risk rather than moderate. Regional risk wording cannot answer the radon question for a Lansdowne residence, so an indoor measurement remains necessary. Describe the lowest level that could be used regularly, including a lower room planned for work, sleep or recreation. Placement stays within the authorized household and accounts for unit boundaries, building access and the device's need for an undisturbed setting.
Lansdowne on the Potomac's homeowners association identifies itself as a defined community on the page checked September 9, 2026. The source applies to Lansdowne on the Potomac only; it should not be stretched to River Creek, Belmont Country Club or every Lansdowne mailing address. Confirm the actual association and residence before using community procedures. The HOA identity provides access context, not evidence about the building form, lower level or radon concentration.
Local background: Lansdowne on the Potomac HOA community page, checked September 9, 2026, Virginia Department of Health high-risk correction for Loudoun, EPA property-testing and zone-map guidance.
01
Use the full street address to identify the governing community, then follow its actual visitor process. Do not transfer the cited HOA’s procedures to a neighboring development.
02
Provide gate authorization for placement and retrieval, along with a backup occupant or agent. Confirm whether visitor approval expires between the two dates.
03
List the residential unit and its lowest regularly usable level, plus any desk or elevator steps. Shared commercial or amenity space needs separate permission.
Where we test in Lansdowne, and what to tell us
Lansdowne on the Potomac and River Creek
For Lansdowne on the Potomac or River Creek, verify which association governs the address. Gate and visitor requirements can only be used after that identity is confirmed.
Belmont Country Club
At Belmont Country Club, arrange technician entry and a return collection route before setup. Community access should not depend on an unavailable resident.
The Village at Leesburg and Coton Commons
Near the Village at Leesburg or Coton Commons, specify the building, floor and unit. Common corridors or amenity rooms do not represent the booked residence.
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.
Virginia's residential disclosure statute directs the seller's disclosure statement to say that the owner makes no representation about whether the property is in an EPA Zone 1 or Zone 2 locality. It directs buyers to use due diligence, including reviewing EPA, Virginia Department of Health and NRSB information and ordering a radon inspection before settlement as the contract allows.
Va. Code section 55.1-703. Current as of September 2026. General information, not legal advice.
It establishes Lansdowne on the Potomac as a defined HOA community. It does not describe River Creek, Belmont Country Club or every address carrying a Lansdowne mailing label.
Register the technician for both service visits, provide the gate route and name an alternate contact. Verify that the collection authorization remains active after the 48-hour minimum.
A common room does not answer the identified residence’s measurement question. The device must be placed within the authorized unit unless a different scope is expressly arranged.
Leave the equipment in its new position, record who moved it and the approximate time, and contact the technician promptly. Do not attempt to recreate the original setup.
