Radon Testing & Mitigation in Wildwood, MO

Wildwood, MO homeowners call Air Sense Environmental for four things: radon testing, radon mitigation, indoor air quality testing and crawl space encapsulation. The NRPP-certified, IEMA-licensed (#RNM20232346) team serves St. Louis County from Edwardsville, Illinois, and designs every radon system to bring the home below the EPA action level of 4.0 pCi/L.

Is radon a problem in Wildwood, MO?

Yes. St. Louis County is in EPA Radon Zone 2, where the predicted average indoor radon level is 2 to 4 pCi/L, and individual Wildwood homes routinely test well above the 4.0 pCi/L action level. Missouri’s Department of Health and Senior Services reports that roughly one in three homes tested through its statewide program between 2003 and 2023 came back at or above 4.0 pCi/L. Wildwood covers the rugged far west of St. Louis County, including Glencoe and Grover, where large-lot homes sit on rocky ground at the edge of the Ozark border and many have walkout basements and private wells.

Because radon depends on the ground under a single lot and the openings in a single foundation, Wildwood results change from address to address. Testing the specific house is the only way to know where it stands.

Radon testing in Wildwood, MO

For radon testing in Wildwood, Air Sense Environmental places a continuous monitor on the lowest livable level for 48 hours and delivers a documented report against the 4.0 pCi/L action level. The St. Louis radon testing page covers how the test works, and the radon testing cost guide holds current pricing.

Radon mitigation in Wildwood, MO

A Wildwood radon mitigation system pulls soil gas from beneath the slab or crawl space membrane and vents it above the roofline; every install ends with a verification test. See radon mitigation in Wildwood for the process, documented results and warranty.

Indoor air quality testing in Wildwood, MO

For indoor air quality in Wildwood, a continuous monitor tracks particulates, VOCs, carbon dioxide, carbon monoxide and humidity, and the report shows which readings sit outside healthy ranges. Details are on the St. Louis indoor air quality testing page.

Crawl space encapsulation in Wildwood, MO

A sealed, conditioned crawl space keeps ground moisture and soil gas from rising into a Wildwood home; Air Sense Environmental installs the barrier, seals the vents and sizes the dehumidifier. Read more on the St. Louis crawl space encapsulation page.

Which Wildwood homes does Air Sense Environmental work on?

The Wildwood homes the team sees most often:

• Large-lot homes with walkout basements on rocky slopes
• Homes in Glencoe and Grover with older foundations
• Homes on private wells, where radon in water can be tested along with air
• Newer subdivision homes on poured basements near Highway 100

What should Wildwood homeowners expect?

1. Test first. A 48-hour continuous monitor test gives the number everything else depends on.
2. Read the report together. You get the hourly data and a plain explanation of what it means for the house.
3. Design the fix. If the reading is at or above 4.0 pCi/L, the system is designed around your foundation during a free in-home estimate.
4. Install and verify. Most systems go in within a single day, and a post-mitigation test confirms the result.
