elevated levels of radon in your home

Having your home tested for radon is important. You might be wondering what comes next if your home tests positive for elevated levels of radon in the home. Anything over 4 picocuries per liter (4 pCi/L) is considered to be unsafe by the EPA. Immediate action should be taken in order to protect your home and your family. It is best to hire a professional radon mitigator to address the elevated levels of radon in your home. Read on to learn more about what radon mitigation involves.

The Steps You Need to Take For Elevated Levels of Radon in the Home

Once a professional radon tester has determined that you have elevated levels of radon in your home, contact a qualified radon mitigator in your area. They have the knowledge and equipment to reduce the radon levels in your home and prevent future issues. These systems will need to be maintained over time to remain effective and radon levels should be tested periodically.

Different Methods of Mitigation

The type of house that you have will usually determine what type of radon reduction method you need. More specifically, the foundation that your home has will be an important factor. When a basement is present, radon can be reduced by using one of these methods:

  • Sub-Slab Suction
  • Drain-Tile Suction
  • Sump-Hole Suction
  • Block-Wall Suction

The most common method is sub-slab suction. A suction pipe is inserted through a floor slab into the soil or rock underneath the home. Depending on how easily air can move through the area under the slab, more than one suction point may need to be installed.

For crawlspace homes, submembrane suction is an effective mitigation method, which includes covering the ground of the crawlspace with a plastic sheet and venting the radon from under the plastic away from the home.

Maintenance of Your Radon Mitigation System

Once you know that your home is prone to elevated levels of radon, you want to make sure that you properly maintain your mitigation system to keep levels from building up again in the future. The manometer that is installed on top of your mitigation pipe will give you a reading that details whether or not the system is working properly.

The number on this meter should never read zero, which would be an indication that the fan is not moving any air through the pipe. If you see a zero, the fix could be as simple as electricity not flowing properly to the fan.

A radon test should be completed once every two years to determine if your mitigation system is working properly. Radon concentrations should always be below 4 pCi/L.
