You should know what the indoor radon level is in any home you consider buying. If you are planning a home inspection, you should include a radon test as well.
In addition, you can test your home before putting it on the market, and if necessary, lower your radon levels. Save the test results and all information about steps taken to fix any problems. This could be a positive selling point.
A short-term real estate transaction radon test is only $150, and you can schedule it with your other home inspections. The radon test is 48 hours in duration and results are provided by email almost immediately after the test is completed. Testing for radon when buying a home is an opportunity to request the seller to cover radon mitigation before moving in.
