5 Tips Checking Your Home for Radon


Share post:

Radon is a naturally occurring radioactive gas that is present in the soil and rocks. It is produced from the decay of uranium and radium, which are common elements found in the earth’s crust. Radon can seep into buildings through cracks and openings in the foundation, causing indoor air pollution. Exposure to high levels of radon has been linked to an increased risk of lung cancer, making it a serious health concern for homeowners.

The good news is that testing for radon is relatively simple and affordable. In this list, we will provide you with some helpful tips for checking your home for radon. By following these guidelines, you can take steps to protect yourself and your loved ones from the harmful effects of radon.

1. Conduct a Radon Test

  • Purchase a radon test kit online or at your local hardware store.
  • Choose between short-term and long-term test kits.
  • Short-term kits can be used for 2-7 days, while long-term kits can be used for 90 days or more.
  • Follow the instructions on the kit carefully to ensure accurate results.
  • Send the kit to a certified lab for analysis.

2. Test All Rooms

  • Test all rooms in your home, including the basement and any rooms that are below ground level.
  • Radon can seep into any room that is in contact with the ground, so it is important to test all areas of your home.
  • Keep windows and doors closed during the test to ensure accurate results.
  • Test during the colder months when your home is more likely to be closed up.
  • Test again after making any significant renovations to your home.

3. Seal Cracks and Openings

  • Identify any cracks and openings in your foundation where radon could enter.
  • Use caulking, sealant, or other materials to seal the cracks and openings.
  • Hire a professional contractor if you need help identifying or sealing the cracks.
  • Keep vents and exhaust fans functioning properly to ensure proper ventilation.
  • Monitor your home’s humidity levels to prevent mold growth, which can also lead to cracks in your foundation.

4. Install a Radon Mitigation System

  • If your home has high levels of radon, you may need to install a radon mitigation system.
  • A radon mitigation system is designed to reduce the levels of radon in your home.
  • This can be done by venting radon out of your home through a pipe system.
  • Hire a professional contractor to install the mitigation system.
  • Be sure to test your home again after the mitigation system is installed to ensure that it is working properly.

5. Retest Every Few Years

  • Radon levels can change over time, so it is important to retest your home every few years.
  • Retest after any significant changes to your home, such as renovations or additions.
  • Retest if you notice any signs of structural damage, such as cracks in your foundation.
  • Retest if you have installed a mitigation system to ensure that it is working properly.
  • Retest if you have moved to a new home or apartment.


In conclusion, checking your home for radon is a crucial step in protecting yourself and your loved ones from the harmful effects of this dangerous gas. Radon is a silent killer that can cause lung cancer, so it is essential to test your home regularly and take steps to mitigate high levels of radon if detected.
