Radon is often found in trace amounts in the air outside your home. A test can reveal whether it’s inside your home, and regular maintenance can help keep it out.
Testing for radon is easy and inexpensive. You can hire a professional to complete the test, or you can use a kit and do it yourself. Some states even offer free testing kits. You simply follow the instructions on the kit and then mail it to the lab for results.
The tasks that help prevent radon in your home are probably already on your maintenance checklist. Inspect your home frequently for cracks or gaps at the building joints and repair any that you find.
