A radon mitigation system is the only permanent fix for high radon. Test kits tell you there’s a problem; sealing cracks barely dents it; opening basement windows lasts exactly as long as the windows stay open. A properly designed mitigation system pulls radon out from under your foundation before it ever enters your home — continuously, quietly, for years at a time.
We design and install radon mitigation systems for homes and businesses across Bowling Green and Warren County, where the average indoor reading of 14.0 pCi/L is among the highest in Kentucky — more than three times the EPA action level of 4.0 pCi/L. Every system we install is verified with a post-installation test, in writing, before we call the job done.
The standard approach is called active sub-slab depressurization, and the concept is simple: instead of letting radon seep up through your foundation, you give it an easier way out.
A sealed PVC pipe is inserted through the slab (or beneath a crawl space membrane) into the soil below. An inline fan — mounted in the attic, garage, or outside the home — runs continuously, creating gentle suction under the foundation. Radon that would have entered your living space gets captured at the source and vented above the roofline, where it disperses harmlessly into open air.
The system includes a manometer, a simple U-shaped gauge on the pipe that shows at a glance whether the fan is maintaining suction. If the fluid levels are uneven, the system is working. If they level out, it’s time to call us.
A well-designed system typically brings even severe readings below 4.0 pCi/L within days — and most homes land well below that.
Bowling Green sits on limestone karst, and karst changes how radon moves. The cracks, voids, and channels in the rock funnel gas unpredictably, which means the suction point that works on one house can underperform on the identical house next door. Cookie-cutter installs are how you end up with a fan that runs for years while doing almost nothing.
Every installation starts with an assessment of your foundation:
Basements. The most common setup in older Bowling Green neighborhoods. Usually a single suction point through the slab, with the pipe routed up through a closet, garage, or exterior wall.
Crawl spaces. The ground gets sealed under a heavy-duty membrane, and the system draws from beneath it — a method called sub-membrane depressurization. In karst country this often solves a moisture problem at the same time.
Slab-on-grade. Newer construction out toward Alvaton and Plano. Suction point placement matters more here, since there’s no basement to work from — routing is designed around your garage or utility areas.
Combination foundations. Part basement, part crawl, part slab — common in homes that have been added onto. These frequently need more than one suction point tied into a single fan and stack.
1. Assess. We evaluate your foundation type, existing radon readings, and your home’s layout to find the right suction point (or points) and the cleanest pipe route.
2. Design. Fan size, pipe run, and discharge location are matched to your structure — not pulled from a one-size template.
3. Install. Most residential systems are installed in a single day. Sealed piping, a quiet inline fan, discharge above the roofline, and a manometer so you can see the system working.
4. Verify. After installation, we retest. The job isn’t done until your numbers are below 4.0 pCi/L — verified, in writing.
In Kentucky, most residential radon mitigation systems fall between $800 and $2,500 installed. A typical single-suction-point system on an accessible foundation lands near the lower-middle of that range. Price moves with your foundation type, the number of suction points needed, pipe routing, and fan size — crawl spaces and combination foundations take more work than open basements.
You’ll get an itemized quote, in writing, before any work starts. No call-for-pricing games, no surprise add-ons on install day.
Mitigation fans wear out — most last around ten years. If your manometer has flatlined, your fan is making new noises, or your latest retest came back high, we repair and replace existing systems, including ones we didn’t install. A fan swap is far cheaper than a new system, and a retest afterward confirms you’re protected again.
We’re local to south-central Kentucky — not a crew dispatched from Nashville or Evansville. We know what karst does under a foundation in a wet spring, why homes off Cemetery Road test differently than homes in Briarwood, and how fast a real estate closing actually moves in this market. When the retest is due or the fan needs replacing in ten years, we’ll still be here.
How long does a radon mitigation system last?
The piping and seals last decades. The fan is the working part — most run 10 years or more before needing replacement. The manometer tells you at a glance that everything’s working.
Is the fan loud?
No. Modern inline radon fans produce a low hum, about as loud as a bathroom exhaust fan — and they’re mounted in attics, garages, or outside, away from living spaces. Most homeowners forget the system is there.
How much does it cost to run?
Radon fans draw roughly as much power as a light bulb. Expect a few dollars a month on your electric bill.
Will the system hurt my home’s appearance or value?
Routing is planned to keep piping discreet — through closets, garages, or along a back exterior wall. And because Kentucky sellers must disclose known radon results, an installed, verified system is a selling point at closing, not a liability.
Can radon levels come back after mitigation?
As long as the fan runs, levels stay down. That’s what the manometer is for — a five-second glance tells you the system is under suction. We also recommend a retest every two years, and after any major foundation or HVAC work.
Do I really need a system if I can just seal the cracks?
Sealing alone doesn’t work. Radon enters through hundreds of pathways — many invisible — and pressure differences pull it in through whatever remains. Sealing is a supporting step that makes a mitigation system more effective, not a substitute for one.
Warren County’s radon averages are among the worst in Kentucky. A mitigation system fixes it — permanently, verified in writing.
