How Much Does Radon Mitigation Cost?

What a radon mitigation system really costs in Illinois, and the factors that move the price up or down.

Completed exterior radon mitigation system on a Central Illinois home

Most residential radon mitigation systems cost between $1,450 and $2,500, depending on your home. The exact price comes down to your foundation and layout, and we always give you a clear estimate up front, with no surprises.

What Affects the Price of a Radon System?

  • Foundation type: a single basement slab is simpler than a basement-plus-crawlspace or a slab-on-grade home that needs extra sealing.
  • Number of suction points: larger or compartmentalized slabs may need more than one.
  • System routing: an interior route through the home vs. an exterior run affects labor.
  • Sump pit: tying into and sealing a sump can change the approach.
  • Fan size: tighter soils need higher-suction (sometimes pricier) fans.

Why a Cheap System Can Cost More Later

A radon system is only worth what it does to your radon level. An undersized fan or a poorly sealed install might look fine but leave you above 4.0 pCi/L, meaning you pay twice. We design it right the first time, use top-grade materials, and guarantee the result.

Is Radon Mitigation Worth It?

For roughly the price of a major appliance, you permanently remove the #1 cause of lung cancer in non-smokers from your home, and protect your property’s value at resale. It’s one of the highest-value health investments you can make in a house.

FAQ

Frequently Asked Questions

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
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.
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.
Do you offer radon testing?
We do not offer radon testing. We install and service radon mitigation systems. For a test, use a licensed Illinois radon measurement professional or a home test kit, then send us your result for a free quote.
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.
