For a home sale, a professional radon test usually runs at least 48 hours with a continuous monitor. If the result is 4.0 pCi/L or higher, a mitigation system can often be installed in a day and retested before closing. We connect buyers, sellers and agents with local radon pros who can work to your timeline.
For buyers
Add a radon test to your inspection. A continuous monitor gives hourly data and shows if anything unusual happened during the test. If the number is high, you can ask the seller to install a system before closing, ask for a credit, or plan to install one yourself after you move in. Your agent can advise which approach fits your contract.
For sellers
If a buyer's test comes back high, don't panic. Radon is a common, fixable finding. Getting an installer scheduled quickly is usually the key. Once the system is in and running, a retest gives the buyer documentation. Some sellers test before listing so there are no surprises.
Timeline that usually works
Day 1 to 3: professional test runs at least 48 hours. Next available day: system install, usually one day. At least 24 hours later: retest with the system running. In practice the whole cycle can fit in about a week if the installer is available, which is why booking early matters.
Avoiding problems
Closed-house conditions must be kept during the test, so sellers should avoid opening windows or running whole-house fans. Monitors with tamper detection help avoid disputes. Make sure the final report includes the test dates, device, location in the home and results.
Common real estate situations
- Inspection report recommends radon testing
- Buyer's test came back at or above 4.0

Frequently asked questions
Who pays for radon mitigation in a home sale?
It's negotiated. Sometimes the seller installs a system, sometimes the buyer gets a credit, and sometimes the buyer handles it after closing. Your real estate agent can help with the wording in your contract.
Can a radon system be installed before closing?
Often yes. Installs usually take a day and the retest needs at least 24 hours of the system running, so a week can be enough if the installer has availability.
Is a 48-hour test enough?
For real estate, a 48-hour professional test is a common standard. A long-term test gives a better average but takes months, which doesn't fit most sale timelines.
The house already has a radon system. Do I still test?
Yes. A system can fail or be unplugged. Test with the system running and check that the manometer shows suction.
Can the seller affect a radon test?
Opening windows or moving the device can skew results. Continuous monitors with tamper sensors and clear closed-house instructions help keep tests fair.
