Radon Mitigation

What is Radon Mitigation?

If your radon test result is 4.0 pCi/l or higher, the United States Environmental Protection Agency (EPA) recommends that you take action to reduce your home or building’s indoor radon levels. But don’t worry! We can lower the radon levels to below 2.0 pCi/l in most cases, and we guarantee our radon mitigation systems will lower your radon to safe levels. Start to finish, the installation process typically takes only one day.

Our Methods
For basement and slab-on-grade foundations, we install a custom-fit sub-slab depressurization system into your home or other building. We often use sealing techniques on any obvious radon entry routes, such as ground water sump pits, cracks in exposed basement floor or walls.

For homes or buildings with crawl spaces, we install a high-density plastic sheet over the crawl space area along with a sub-membrane suction system.

We guarantee that a KHI-installed radon reduction system will lower the radon levels to below 4.0 pCi/l in any building. A majority of the time, our systems lower the radon levels to below 2.0 pCi/l.
