Radon Mitigation in Wildwood, MO

Radon mitigation in Wildwood, MO fixes a home that tested at or above the EPA action level of 4.0 pCi/L. Air Sense Environmental installs sub-slab and sub-membrane depressurization systems across St. Louis County, routes the fan outside the living space, and retests to confirm the number came down.

Does a Wildwood home need radon mitigation?

Mitigation follows measurement. If a Wildwood home tests at or above 4.0 pCi/L the EPA recommends a system, and readings between 2 and 4 pCi/L are worth discussing. 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. If the home has not been tested yet, start with the St. Louis radon testing page.

Which radon mitigation system fits a Wildwood home?

The system follows the foundation:

• Basement slab: sub-slab depressurization, the most common system in Wildwood
• Crawl space: sub-membrane depressurization under a sealed vapor barrier
• Sump pit: a sealed sump lid tied into the system, covered in the sump pump radon mitigation guide
• Slab-on-grade: a suction point routed through a garage, closet or exterior wall
• Mixed foundations: multiple suction points balanced on one fan

The Wildwood homes Air Sense Environmental mitigates 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

How is a radon mitigation system installed in Wildwood?

1. Assessment and diagnostics. The foundation, sump, cracks and pipe route are checked during a free in-home estimate.
2. Suction point. A core hole through the slab, or a sealed membrane in a crawl space, gives the fan something to pull from.
3. Pipe and fan. PVC pipe runs to a fan mounted outside the living space, in the attic, garage or on an exterior wall, and vents above the roofline.
4. Sealing. Cracks, the sump lid and other openings are sealed so the fan can hold suction.
5. Manometer and verification. A U-tube manometer shows the system is running, and a post-mitigation test proves the result.

Most Wildwood installations are completed in a single day. The full walk-through is on the radon mitigation system installation page.

How much does radon mitigation cost in Wildwood, MO?

Air Sense Environmental quotes each Wildwood job after seeing the foundation, because suction points and fan size drive the cost. For current ranges by system type, see the St. Louis radon mitigation cost guide.

How do you know the radon mitigation system worked?

A post-mitigation radon test is the only proof. Air Sense Environmental includes it, designs Wildwood systems to a target well below the 4.0 pCi/L action level, and recommends retesting every two years. When a fan eventually wears out, radon fan replacement restores the system.
