Radon Testing

Radon Testing for Central Illinois

Most of Illinois sits in EPA Radon Zone 1 — the highest-risk zone. Radon is the second-leading cause of lung cancer in the United States. Testing is the only way to know whether the home you're buying — or living in — has a problem.

How It Works

  1. We place a continuous radon monitor in the lowest livable area of the home.
  2. The monitor runs for 48 hours under "closed-house" conditions (windows shut, normal HVAC operation).
  3. We retrieve the device and email you a report with the average level in pCi/L.

What the Numbers Mean

Pricing

Mitigation systems typically run $1,200–$2,500 installed and reduce levels dramatically. We don't sell mitigation — that keeps the test honest.
