Radon is an invisible, odorless radioactive gas that rises from the soil into 1 in 5 homes — and it's the #2 cause of lung cancer. You can't see it, smell it, or taste it. We can. We find it, fix it, and guarantee it's gone. Kits ship today; mitigation as soon as tomorrow.

Radon is a naturally occurring radioactive gas that seeps up from the soil into your home. Long-term exposure is the leading cause of lung cancer among non-smokers.
The EPA and Surgeon General rank radon second only to smoking — and #1 for people who've never smoked. An estimated 21,000 deaths a year in the U.S.
Our region — Northern Illinois and Southern Wisconsin — sits in a high-radon zone. Many local homes test above the EPA's 4.0 pCi/L action level.
Modern homes are built more airtight and energy-efficient than ever. That seals in conditioned air — and the soil gas, including radon, right along with it.
Your home is slightly warmer than the ground beneath it, so it acts like a chimney — gently pulling soil gas up through every opening in the foundation.
Radon is fixable. A properly designed sub-slab depressurization system captures the gas before it enters and vents it safely above your roofline — quietly, permanently, and backed by our guarantee.

Order your kit or book a pro test. Set it, wait 48 hours, get clear results.
If levels are high, we assess your foundation and design the right system for your home.
Most systems install in a single day — sealed sump, suction point, sealed pipe, quiet fan.
We run a post-mitigation test to confirm safe levels — and back it with our guarantee.
Start with a loaner, or keep a quality monitor for ongoing peace of mind. Every kit includes next-day mitigation scheduling if you need it.

Meet the Team →The EPA recommends taking action at 4.0 pCi/L or higher, and considering it between 2–4 pCi/L. There's no truly "safe" level, so lower is always better. We aim to get every home well below 4.0.
Most systems are installed in a single day by one technician. We then place a post-mitigation test to confirm the system is working before we call it done.
Positively. A documented, guaranteed radon system is a selling point — and our guarantee transfers to the buyer. Many real-estate deals require radon to be addressed anyway.
No. The fan is quiet and runs continuously in the background, and we route piping cleanly with minimal clutter. You'll barely know it's there.
Open sump pits are one of the biggest radon entry points. We seal them with a gas-tight, serviceable cover as part of the system, so your pump still works and the radon stays out.
Order a kit above, or send us a note and we'll reach out — usually same day.
