Documentation Before We Leave
Every install comes with written documentation from a state licensed mitigator. Useful for real estate files, tenant records, and your own home records.
What the System Is Actually Doing
Radon is measurable and fixable. These two views show why testing matters and why a mitigation system is designed around the whole home, not just one visible crack.
Pressure under the home finds small openings
Radon usually is not coming from one single hole. Pressure under the home lets soil gas move upward through porous concrete itself, sump openings, crawl spaces, cracks, and small gaps around pipes.
The fan creates the easier path out
A mitigation fan creates a lower-pressure path under the home, so radon is pulled into the pipe before it enters the living space, then vented above the roofline.
From the First Call to Done
Bill reviews the home, we schedule the install, and our crew gets the system built cleanly. Most jobs are finished in a single visit. Here's how it goes, step by step.
