Radon System Repair & Service

Loud, leaking, or underperforming radon system? We diagnose and repair systems of any age or brand.

Sealed sump pit and suction point for a radon mitigation system

A radon system only protects you if it’s working. If yours is noisy, leaking condensation, showing no pressure on the manometer, or your radon has crept back up, we’ll find the problem and repair it, even if another company installed it.

Common Radon System Problems We Repair

  • Failed or noisy fan: the most common issue (we replace any brand).
  • Cracked or disconnected piping that kills suction.
  • Failed slab or sump seals letting radon bypass the system.
  • Improper original design that never fully solved the problem.
  • Manometer reading even: a sign the system isn’t depressurizing.

How Service Works

We inspect the full system, fan, piping, seals, and suction, identify what’s failing, and give you a straight answer and a fair price. In many cases a fan replacement restores full protection the same day. When a system was undersized or poorly designed from the start, we’ll redesign it so it actually keeps your home below 4.0 pCi/L.

FAQ

Frequently Asked Questions

My fan stopped working / my system is loud. Can you help?
Yes. We install, replace, and repair radon fans of every brand, even systems we didn’t install. A humming, rattling, or silent fan usually means it’s time for a replacement. See our radon fan service
Will the system really lower my radon?
Yes, and we guarantee it. A properly designed sub-slab depressurization system routinely brings homes from double-digit radon levels down below the EPA action level of 4.0 pCi/L. We recommend a follow-up test to confirm the result in writing, and if it isn’t below 4.0, we’ll come back and make it right.
How long does installation take?
Most systems are installed in about half a day, and you can stay home while we work. It can take a little longer for larger homes, bigger crawlspaces, or older homes that need multiple suction points or more complicated work, but most are still done within one day.
How much does a radon mitigation system cost?
Most residential radon mitigation systems run $1,450–$2,500, depending on your foundation, the layout of your home, and where the system routes. We give a free, no-obligation estimate up front, no surprises. See what affects the price
Are you licensed and insured?
Absolutely. We’re a Licensed Radon Mitigation Specialist through the Illinois Emergency Management Agency (IEMA), license #RNM2020203, and fully insured. Radon mitigation in Illinois must be performed by a licensed professional.
