Is Air Sense Environmental certified for radon mitigation in Missouri?

Yes. Air Sense Environmental is licensed through IEMA/#RNM20232346. All radon mitigation work is performed by Jake Lusby. Certified contractors are required to follow EPA-approved mitigation standards and conduct post-installation testing to verify system performance.

How long does a radon mitigation system installation take?

Most radon mitigation systems are installed in a single day, typically 1-3 hours for a standard home. After installation, we conduct a post-mitigation radon test to confirm levels are below the EPA action level of 4 pCi/L. You can usually return to normal activity the same day.

What type of radon mitigation system do you install?

The most common system we install is sub-slab depressurization (SSD), which draws radon from beneath your foundation and vents it safely outside through a PVC pipe and fan system. The right approach depends on your home’s foundation, basement, crawl space, or slab-on-grade — which we assess during the free estimate.

Does radon mitigation really work?

Yes. Properly installed radon mitigation systems reduce indoor radon levels by up to 99% in most homes. We conduct a post-installation radon test on every job to confirm your levels are below the EPA action level before we consider the project complete.

What is the difference between radon testing and radon mitigation?

Radon testing measures the concentration of radon gas in your home, it’s how you find out whether you have a problem. Radon mitigation is the installation of a system designed to reduce that concentration to safe levels. Testing always comes first; mitigation is only recommended if results exceed the EPA action level of 4 pCi/L. Air Sense Environmental offers both services.

Does Air Sense Environmental serve my area?

In most cases, no. Radon mitigation installation does not require you to vacate your home. The work is typically completed in a single visit with minimal disruption, and Jake’s team will walk you through what to expect before the appointment.

What happens if my radon levels are still high after mitigation?

If a post-mitigation test shows levels are still at or above 4 pCi/L, we assess the system and make the necessary adjustments, which may include upgrading the fan, adding a second suction point, or sealing foundation entry points. Air Sense Environmental stands behind every installation and won’t close a job until your radon levels are confirmed safe.
