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 City of Manassas Park
A radon test in Manassas Park 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 rate covers one Manassas Park residence; provide unit and keyholder information. Provide a backup access contact when commuter schedules could prevent the primary resident from meeting the technician at retrieval. Confirm the report recipient when booking.
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 Manassas Park.
Manassas Park is an independent Virginia city, distinct from Manassas and Prince William County. Numerical county radon zones should not be transferred to a Manassas Park address. Virginia Department of Health guidance recommends testing every home, so the selected residence needs its own indoor measurement.
Manassas Park is an independent city, separate from Manassas and Prince William County. At Bloom’s Crossing, Manassas Park Village or Belmont Station, identify the exact dwelling and current low-level room use rather than relying on a neighboring layout. At Bloom’s Crossing, tell the technician whether the appointment concerns a house or an attached unit and identify any separately occupied space. A Manassas Park Village owner should clear an accessible location on the lowest level that could be used regularly, including a future office or bedroom. Belmont Station residents may need association, tenant or agent coordination for two visits. Choose dates after moving, flooring or mechanical work is complete, and notify everyone entering the home not to move the equipment. When an interruption occurs, note its time and nature rather than changing monitor settings. The resulting report applies to the tested Manassas Park residence and should not be represented as evidence for Manassas City or Prince William County homes.
