Who pays for radon testing and mitigation in a home sale?

That is typically negotiated between the buyer and seller as part of the purchase contract. We provide the test and, if needed, the mitigation quote, and you and the other party work out the terms.

Does a high radon result kill a sale?

Not usually. Mitigation is a well-established, relatively quick fix, often installed in a single day, so a high result more often becomes a negotiation point than a deal breaker.

For buyers

A radon test during the inspection period tells you what you are actually buying. If the result comes back at or above the EPA action level of 4 pCi/L, that becomes part of the negotiation, whether that means asking the seller to mitigate before closing or factoring the cost into your offer.

For sellers

Testing before you list means no surprises mid-negotiation. If the result is high, you have time to get a mitigation system installed on your own schedule rather than under contract deadline pressure, and a documented low result can be a point in your listing's favor.

Working within inspection timelines

Real estate radon tests are almost always short-term tests, two to seven days, specifically because contracts do not leave room for a ninety-day long-term test. We schedule quickly and follow the placement protocols buyers, sellers and lenders expect to see on a real estate radon report.

If mitigation is needed before closing

If a pre-closing test comes back high, a sub-slab depressurization system is typically installed in a single day, and we can often turn around installation and a post-mitigation confirmation test fast enough to fit inside a typical closing timeline. Talk to us early if you are already anticipating this.
