Radon Mitigation on the Illinois Side of St. Louis

IEMA-Certified NRPP-Certified BBB A-Rated Edwardsville HQ

Radon mitigation on the Illinois side of St. Louis is handled from our Edwardsville headquarters, which puts our crews inside the Metro East rather than driving over from Missouri.

We hold IEMA license #RNM20232346 for radon work in Illinois.

We serve twenty Metro East communities, from Jerseyville and Alton in the north down to Columbia and Waterloo.

Licensing

Illinois Licensing and What It Means

Illinois regulates radon professionals through the Illinois Emergency Management Agency.

Measurement and mitigation both require a current state license, and the number belongs on any proposal you receive. Ours is #RNM20232346.

If you are collecting quotes on the Illinois side, ask each contractor for theirs.

Local Conditions

Why Testing Your Own Address Matters

Radon levels vary block to block and even between neighboring houses.

Two homes on the same street with different foundations and different air handling can test very differently, so a county average is not a substitute for testing your address.

The Work

Our Mitigation Approach

We design each system around the foundation we find rather than fitting every house to one template.

Sub-slab depressurization is the most common approach, with the suction point and fan sized to the building. Systems are engineered below the EPA action level of 4.0 pCi/L.

After installation we recommend a follow-up radon test to confirm the result.

Testing

Radon Testing on the Illinois Side

We test as well as mitigate, including tests tied to a home sale.

If you are buying or selling in the Metro East and need a reading inside an inspection window, results come back in two to three business days.

Experience

Local Crews, Local Work

Being based in Edwardsville means Illinois work is local work for us, not a trip across the river.
