Radon is a naturally occurring radioactive gas that seeps up from soil into homes — and the Quad Cities sits in a region where elevated indoor radon levels are common in both Iowa and western Illinois. You can't see or smell it, and long-term exposure is the second leading cause of lung cancer after smoking. The good news is that testing is inexpensive and a properly installed mitigation system brings levels down to safe. The contractors listed here handle radon testing, system installation, and follow-up across all five Quad Cities.

Frequently Asked Questions
Is radon really a problem in the Quad Cities?
Yes — Iowa has some of the highest average indoor radon levels in the country, and western Illinois, including Rock Island and the Moline area, is also in a high-risk zone. The geology that produces the gas is regional, and the stack effect in older homes with basements pulls it indoors. The only way to know your level is to test, because radon varies house to house even on the same block.
How do I test my home for radon?
A short-term test kit (2 to 7 days) gives a quick read; a long-term test (90+ days) gives a more accurate average. Short-term kits run $20 to $30 and are widely available; a professional measurement is more thorough and is the better choice if you're buying a home. Place the kit in the lowest livable level, follow the closed-house conditions on the instructions, and send it to the listed lab. If the result is at or above 4 pCi/L, mitigation is recommended.
What does a radon mitigation system involve?
The standard fix is sub-slab depressurization: a pipe is inserted through the basement floor and routed up and out of the home, with a continuously running fan that draws soil gas from beneath the slab and vents it above the roofline before it enters the house. A properly installed system typically brings radon levels below 2 pCi/L. Most installations are a one-day job by a licensed mitigation contractor.
Does a radon mitigation system require ongoing maintenance?
Very little — the fan runs continuously and typically lasts 5 to 10 years before needing replacement, which is a straightforward service call. Retest radon levels every two years or after any major foundation change to confirm the system is still effective. A system with a manometer on the pipe lets you check at a glance that the fan is still pulling a vacuum; if the reading changes, call the installer.
