Professional Radon Testing in Loganville and Gwinnett County
Know what you cannot see or smell.
Radon is an invisible, odorless radioactive gas that can enter a building from the soil. Testing measures its concentration during the test period. Friendly Home Inspections LLC provides radon testing in Loganville, Lawrenceville, Dacula, Grayson, Snellville, and nearby communities for buyers, sellers, homeowners, landlords, and new homes. Request it as an additional service with a home inspection or arrange a separate test.
Test the home—not assumptions.
EPA recommends testing homes, including newly built homes and those with radon-resistant features.
✅ Age, appearance, or the absence of a basement does not rule out elevated radon
✅ A neighbor’s low result does not predict your home’s result
✅ Soil, building openings, ventilation, weather, and operation can affect measurements
✅ EPA recommends fixing homes at 4 pCi/L or higher; levels below 4 still carry risk
✅ Interpret the report using current EPA guidance and applicable transaction requirements
A passive radon system does not prove the level is low. A qualified mitigator can advise on activation or other corrective work when indicated.
Protect the test conditions
Allow enough time for setup, the full measurement period, retrieval, and reporting before your deadline.
✅ Give occupants and agents the written preparation instructions
✅ Maintain the required closed-building and HVAC conditions
✅ Do not touch, move, unplug, or adjust the test device
✅ Avoid open windows, prolonged open doors, unusual ventilation, and interfering work
✅ Tell us promptly about power loss, unauthorized entry, or conditions that cannot be maintained
For new construction, coordinate with the builder: the home must be enclosed, substantially complete, and able to maintain the required conditions. Interference or unsuitable conditions can complicate or invalidate a result.
Understand the measurement. Plan the next step.
Your report states the measured concentration and relevant conditions or interruptions.
✅ A short-term result does not guarantee identical levels in every season or year
✅ Follow-up testing depends on the result, test type, transaction needs, and current guidance
✅ Consult a qualified mitigation professional when corrective work is indicated
✅ Discuss system design, activation, installation, and post-mitigation testing with that professional
✅ Provide the address, deadline, occupancy, foundation type, and inspection plans when booking
Friendly Home Inspections does not install mitigation systems. Before testing, address conditions that prevent required building operation, such as broken exterior windows or doors. Call or text 404-981-4615 to arrange testing.
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.
