Radon Eliminator holds Ohio Radon Mitigation License RC202 — the credential the Ohio Department of Health requires for anyone installing a mitigation system on a home, apartment, school, or commercial building in this state. We lead with that number because most companies bury it. If a contractor can't put their RC202 on the quote, they can't legally seal the work.

Greene County and the broader Jamestown area sit on the same fractured limestone and glacial-till geology that puts much of western Ohio in EPA Radon Zone 1 — the highest-risk classification. The Ohio Department of Health's county-level data consistently shows average indoor radon readings here above the 4.0 pCi/L action level. That isn't fear-mongering; it's the reason your inspector flagged your home in the first place.

Here is what makes Radon Mitigation Jamestown Radon OH different when you call us:

• Closing-Date Radon Service: We schedule installs around your purchase agreement, not our convenience. Most Jamestown-area homes can be mitigated and re-tested inside the standard 10–14 day inspection-response window.
• Fixed, written pricing: No "we'll see when we get there." You get a flat quote before we unload a tool.
• EPA-aligned protocols: Pre- and post-mitigation testing follows EPA Indoor Radon Quality Assurance guidance — the documentation your lender, title company, or school board needs.
• Multi-vertical depth: Single-family, multi-family, school district, and commercial work. Most local shops only handle one type of building.
• Home-inspector partner program: A published referral structure for the inspectors who flag the problem in the first place.

We don't sell fans. We sell a complete, documented, code-compliant professional Radon Mitigation Jamestown Radon OH system that drops your indoor radon below the EPA action level of 4.0 pCi/L — and we prove it with a post-install short-term test you can hand to anyone who asks.

The gold-standard mitigation method for the slab-on-grade ranches, finished basements, and walkout homes common throughout Jamestown and the surrounding Cedarville–Xenia corridor. We core through the slab, evacuate the soil-gas column beneath your foundation, and vent it above the roofline with a sealed PVC stack and a continuously running radon fan sized to your home's footprint. Installed correctly the first time, an ASD system routinely brings readings from the 8–15 pCi/L range down to under 2.0 pCi/L.

Older Jamestown farmhouses and rural Greene County homes often have partial or full crawl spaces. We install a 12-mil reinforced vapor barrier, seal every penetration, and pull a vacuum on the membrane — eliminating both radon entry and the moisture problems that come with bare dirt crawl spaces.

Ohio law requires schools and certain licensed facilities to address elevated radon. We design multi-point mitigation systems for apartment complexes, daycare centers, manufacturing floors, and K–12 buildings. Engineered drawings, manometer dashboards, and annual re-test contracts are all part of the package.

EPA-aligned 48-hour continuous radon monitor tests with chain-of-custody documentation. This is the testing your real-estate transaction, refinance appraisal, or school inspection needs. Results are typically delivered the same day the monitor is retrieved.

Bought a home with a system that doesn't work? We inspect the fan, manometer, suction points, and venting. About a third of the existing systems we evaluate in Greene County are either undersized, improperly vented, or have failed fans the homeowner never noticed. We repair or replace to current Ohio code.

Every Radon Mitigation services Jamestown Radon OH project follows the same five-step protocol. It's how we deliver a documented number under 4.0 pCi/L on the first try.

Step 1: Phone Diagnosis & Fixed Quote (Same Day)

Tell us your test result, your foundation type, and your timeline. In most cases we can quote your system over the phone within 15 minutes. If you're inside a purchase agreement, we put your closing date at the top of the schedule.

Step 2: On-Site Diagnostic Visit

A licensed Ohio technician inspects your foundation, sub-slab communication, sump configuration, and existing penetrations. We identify the optimal suction point — usually a location that keeps the exterior stack out of sight from the curb.

Step 3: Code-Compliant Installation

Most single-family installs take 4–6 hours. We core the slab, seal cracks and the sump cover, run sealed Schedule 40 PVC, install a properly sized Radonaway or Festa fan, mount a U-tube manometer, and label the system per Ohio Department of Health requirements.

Step 4: Post-Mitigation Testing

A continuous radon monitor runs for a minimum of 48 hours in the lowest livable level of the home. You receive a stamped report showing the hour-by-hour readings, the average, and the certifying license number (RC202).

Step 5: Documentation Package

You get the system warranty, the post-mitigation test report, the manometer baseline reading, and a maintenance schedule. This is the package real-estate attorneys, lenders, and school district administrators expect.

Jamestown sits in the southeastern corner of Greene County, surrounded by the agricultural communities of Bowersville, Cedarville, Xenia, and Sabina. The homes here range from 1880s farmhouses with stone foundations along US-35 to newer builds in subdivisions off Washington Street and OH-72. Each foundation type calls for a different mitigation strategy, and we've worked on all of them.

We routinely service homes near Silvercreek Township, the Jamestown Reservoir area, properties along Jasper Road and Cottonville Road, and the older streets surrounding Jamestown Park and the downtown corridor on West Xenia Street. The Greene County Soil Survey shows the area is dominated by Miamian and Crosby silt loams over fractured limestone — exactly the geology that drives Ohio radon levels up.

We also serve real-estate transactions across the broader region — Beavercreek, Fairborn, Yellow Springs, Wilmington, Washington Court House, and the Dayton suburbs. If your closing is in southwestern Ohio, we can be on-site fast. As Ohio's licensed radon authority, we coordinate with most major Greene and Clinton County real-estate brokerages and home-inspection firms.
