Selling a House With Radon
An elevated result does not automatically prevent a home sale. The parties should handle test conditions, records, mitigation scope, and applicable disclosure rules carefully.
Seller checklist
Keep prior reports and system records, do not interfere with test conditions, keep an existing system operating normally, and put negotiated scope, timing, payment, and post-mitigation testing in writing.
Buyer checklist
Ask for prior results, confirm whether testing follows the transaction protocol, independently check professional credentials where applicable, and consider appropriate post-closing or post-mitigation testing.
Legal note
Disclosure, testing, licensing, and real-estate rules vary. Ask a local real-estate professional or attorney; this page is general education, not legal advice.
