IEMA-Certified Free In-Home Estimates

Is radon a problem in Columbia, IL?

Yes. Radon levels in Monroe County vary widely from house to house, and individual Columbia homes routinely test above the EPA action level of 4.0 pCi/L. 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. Columbia sits on Monroe County’s karst plain, where sinkholes, caves and fractured limestone give soil gas open pathways toward the surface.

Radon varies house by house rather than neighborhood by neighborhood. Two homes on the same Columbia street, built the same year by the same builder, can test at 1 pCi/L and 12 pCi/L because of what sits under each lot and how each foundation was sealed.

Radon testing in Columbia, IL

Radon testing in Columbia uses a calibrated continuous radon monitor for a 48-hour closed-house test, with hourly readings and tamper detection that hold up in a real estate transaction. The St. Louis radon testing page covers how the test works, and the radon testing cost guide holds current pricing.

Radon mitigation in Columbia, IL

Radon mitigation in Columbia means a sub-slab depressurization system designed around the specific foundation, with the fan outside the living space and a post-mitigation test to prove the result. See the St. Louis radon mitigation services page for the process, documented results and warranty.

Indoor air quality testing in Columbia, IL

Indoor air quality testing in Columbia measures particulates, VOCs, carbon dioxide, carbon monoxide, temperature and humidity over at least 48 hours, with radon as an optional add-on, and ends in a written report. Details are on the St. Louis indoor air quality testing page.

Crawl space encapsulation in Columbia, IL

Crawl space encapsulation in Columbia seals the floor and walls with a reinforced vapor barrier, closes the vents and controls humidity with a dehumidifier, which also cuts off a common radon pathway. Read more on the St. Louis crawl space encapsulation page.

Which Columbia homes does Air Sense Environmental work on?

The Columbia homes the team sees most often:

  • Historic homes along Main Street with stone foundations
  • 1980s to 2000s subdivision homes on poured basements
  • Homes built near mapped sinkholes, where the bedrock is fractured
  • Homes on private wells in the rural edges of town

What should Columbia 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.
