Real Estate Radon FAQs
When should radon testing be done in a Marietta real estate transaction?
Testing should be scheduled during the inspection period. Since tests require a minimum of 48 hours under closed-home conditions, coordinate with your agent early. We can typically accommodate tight closing deadlines with advance notice.
Is radon disclosure required in Georgia?
Georgia law requires sellers to disclose known material defects. If you've tested and found elevated radon, this should be disclosed. Many Cobb County agents now recommend pre-listing tests to avoid surprises during buyer inspections.
What if the Marietta home I'm buying has high radon?
Elevated radon doesn't have to be a dealbreaker. Mitigation systems cost $900-$2,500 in Cobb County and typically reduce radon by 90%+. Use test results to negotiate seller-paid mitigation or a price credit covering buyer-arranged installation.
Should I test before listing my Marietta home?
Pre-listing testing is increasingly common in Cobb County. Low results reassure buyers. If levels are elevated, you can mitigate before listing—a mitigation system with post-install testing showing low radon is a selling point.
How quickly can you provide results for closing?
Short-term tests require minimum 48 hours. Results are available immediately after testing concludes. For tight deadlines, contact us as early as possible—we prioritize real estate transactions.
Do Cobb County lenders require radon testing?
Most lenders don't require radon testing, but many buyers include it in their inspection contingency. FHA and VA loans don't mandate radon tests, though the EPA recommends testing all homes before purchase.
