how radon enters home

Our homes are supposed to be safe places, and it often feels like nothing can get to us when we are behind those doors. Unfortunately, there is one harmful thing that can enter your home undetected: Radon gas. 

Radon is a natural byproduct of uranium in the soil below homes and is odorless, tasteless, and colorless. Even more, it’s also the second leading cause of lung cancer in the United States, second only to smoking.

How radon enters your home

In order to keep radon out of your home, you first must understand how it enters. The main way radon enters your home is through pores, cracks, and other openings in the foundation. Radon is pulled into your home through a vacuum created by lower air pressure in your home compared to the pressure in the soil. It can also enter through sumps, construction joints, and drains, and can pass through most surfaces that are in contact with the soil, including your concrete foundation.

It would seem logical that you can seal cracks and openings around construction joints or sumps to stop radon from ever entering your home. However, radon gas particles are so small they can’t be seen, which means they can enter through cracks and pores that can’t be seen either. Sealing and caulking can help, but it is not usually enough to reduce radon to a safe level.

What can be done about high radon levels?

Don't be discouraged if you have tested your home and found high radon levels. Radon levels can be quickly reduced with a radon mitigation system that pulls the radon from the soil and releases it above the home.
