Radon Testing & Mitigation in Jerseyville, IL

In Jerseyville, IL, Air Sense Environmental tests homes for radon, installs radon mitigation systems, tests indoor air quality and encapsulates crawl spaces. Every radon job in Jersey County is measured against the EPA action level of 4.0 pCi/L, and the team is NRPP-certified and IEMA-licensed (#RNM20232346).

Is radon a problem in Jerseyville, IL?

Yes. The Illinois Department of Public Health reports that about 41 percent of Illinois homes tested have come back at or above 4.0 pCi/L, and Illinois requires radon professionals to hold an IEMA license. Jerseyville is the seat of Jersey County, which the EPA places in Radon Zone 1, its highest-potential category, with a predicted average indoor level above 4 pCi/L.

A Jerseyville neighbor’s reading is a signal, not an answer. The soil under one lot, the cracks in one slab and the way one sump pit was sealed decide the number, which is why two similar homes a few doors apart can land on opposite sides of the action level.

Radon testing in Jerseyville, IL

A Jerseyville radon test runs 48 hours under closed-house conditions on a calibrated continuous monitor, and the report shows the hourly data as well as the average. The St. Louis radon testing page covers how the test works, and the radon testing cost guide holds current pricing.

Radon mitigation in Jerseyville, IL

When a Jerseyville home tests at or above 4.0 pCi/L, the same team designs and installs the radon mitigation system, usually in a single day, and retests to confirm the home is below the action level. See the St. Louis radon mitigation services page for the process, documented results and warranty.

Indoor air quality testing in Jerseyville, IL

An indoor air quality assessment for a Jerseyville home logs particulate matter, chemical vapors, CO2, CO and humidity at one-minute intervals for 48 hours or more, so the fix is based on data. Details are on the St. Louis indoor air quality testing page.

Crawl space encapsulation in Jerseyville, IL

For Jerseyville homes with a crawl space, encapsulation lays a sealed vapor barrier over the soil and walls and adds humidity control, keeping damp air and soil gas out of the rooms above. Read more on the St. Louis crawl space encapsulation page.

Which Jerseyville homes does Air Sense Environmental work on?

The Jerseyville homes the team sees most often:

• Older homes near the courthouse square with stone or block basements
• Mid-century ranches with basements
• Farmhouses and rural homes on private wells
• Newer homes on poured basements on the edges of town

What should Jerseyville 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.
