Peace of mind. Know your home is protected with expert radon testing.

Steps for DIY radon testing:

Step 1: Order a Two-Pack of radon test kits online by contacting Woods Basement Systems, Inc.. The EPA recommends performing two kits simultaneously and averaging the results. This is the most cost-effective and accurate way to test your home. Only $22.00 per kit, including shipping and lab fees. It's not required to order two test kits, but we recommend it.

Step 2: Conduct the radon test. Your radon kits will come with some simple instructions that you can follow. Setting up a radon test is easy, and should take no longer than a few minutes of your time. Be sure to pay special attention to instructions that mention closing windows and doors, and locating the test kit in the lowest area of your home (very often the basement). If your home has a crawl space only, then place the test kits in the middle of an interior room, away from doors and windows.

The test will remain in your home for at least 48 hours and must not exceed 72 hours in order to provide an accurate picture of the radon level. Because the concentration of radon gas varies greatly from day to day, a short-term radon test does not provide an accurate analysis of the radon concentration in your home.

Step 3: Send out your radon test package. Once the data has been collected by your radon test kit, carefully reseal the package and send it to the lab site specified on the package immediately for analysis. Within a few weeks, the results of your test should arrive.

What your test results mean

Depending on your radon test results - from either testing method, you can decide if further action is required in your home. If your results show 4.0 pCi/L or higher, contact Woods Basement Systems, Inc. for a free Radon Mitigation System estimate.

Many homeowners will seek mitigation services even if the results are lower -- as there is no "healthy" level of radon, and many organizations have a much lower recommended action level than 4.0 pCi/L (for example, the World Health Organization sets the radon action level at 2.7 pCi/L). Radon levels can be controlled by installing a radon mitigation system in your home. Radon Mitigation Systems are affordable and installed in only one day by our highly trained and skilled technicians!
