Professional Radon Testing in Loganville and Gwinnett County

Why testing matters

The U.S. Environmental Protection Agency recommends that homes be tested for radon. EPA recommends

taking action to reduce radon when the measured level is 4 picocuries per liter (pCi/L) or higher and notes that

levels below 4 pCi/L still carry some risk. The test report should be interpreted using current EPA guidance and any applicable transaction requirements.

A low result in a nearby property does not predict the result in your home. Construction details, soil conditions, ventilation, foundation openings, weather, and building operation can influence measurements.

Testing during a real-estate transaction

Radon testing should be scheduled early enough to complete the required measurement period and receive the result before the due-diligence deadline. The property must remain under the required closed-building conditions, and windows, exterior doors, ventilation equipment, fireplaces, and HVAC settings must be managed according to testing instructions.

The occupants and agents should receive written preparation requirements. Interference, power loss, moved equipment, open windows, unusual ventilation, or unauthorized entry can invalidate or complicate the result. The testing device should not be touched or relocated.

New homes should be tested too

New construction and radon-resistant features do not eliminate the need to measure. EPA states that the only way to know whether a new home has a radon problem is to test. A passive radon system may need activation by a qualified mitigator if testing indicates an elevated concentration.

When combining radon testing with a final new-construction inspection, coordinate access and building conditions with the builder. The home should be enclosed, substantially complete, and capable of maintaining the required testing conditions.

Understanding the result

The report states the measured radon concentration for the test period and identifies relevant test conditions or interruptions. A short-term result is a measurement, not a guarantee that the level will remain identical throughout every season or year. Follow-up testing may be recommended based on the result, test type, transaction needs, and current guidance.

Friendly Home Inspections does not install mitigation systems. If mitigation is indicated, consult a qualified radon mitigation professional about design, installation, activation, and post-mitigation testing.

Protect the validity of the test

Before testing, correct conditions that make closed-building operation impossible, such as broken exterior windows or doors that cannot remain closed. Do not begin construction, painting, large ventilation changes, or other activities that could affect indoor air movement during the measurement. Routine entry and exit should be minimized and exterior doors should not be left open.

If test conditions cannot be maintained, inform Friendly Home Inspections immediately rather than attempting to adjust the device.

Schedule radon testing

Call or text 404-981-4615 with the property address, transaction deadline, occupancy status, foundation type if known, and whether the test will accompany a home inspection. Allow enough time for setup, the full measurement period, retrieval, and reporting.

Radon testing FAQs

Can I tell whether a house has radon without testing? No. Radon cannot be seen or smelled.

Is 4 pCi/L considered the only level with risk? No. EPA notes that levels below 4 pCi/L still pose some risk.

Does a passive radon pipe prove the level is low? No. The home should still be tested.

Can occupants open windows during testing? Closed-building conditions must be followed except for normal brief entry and exit.
