If your inspector handed you a radon number above 4.0 pCi/L, or your buyer's agent is asking for a radon test before closing, you need two things: a straight answer and a permanent fix. Radon Eliminator delivers both. We are Ohio's licensed radon mitigation company (Ohio Mitigation License RC202), and Radon Mitigation in Chesterville, OH is our core service — not a side offering tacked onto a general contracting menu.

Chesterville sits in Morrow County, inside EPA Radon Zone 1 — the highest-risk zone for indoor radon in the United States. That means homes along State Route 314, properties near Whetstone Creek, and the older farmhouses scattered between Chesterville and Mount Gilead routinely test above the EPA action level of 4.0 pCi/L. This isn't a fluke. It's the geology of central Ohio's glacial till and limestone bedrock pushing radon gas up through basement slabs, crawl spaces, and sump pits.

We handle the problem the way the EPA, AARST, and Ohio Department of Health expect it to be handled: sub-slab depressurization, sealed entry points, a properly sized fan, a U-tube manometer, and a post-mitigation test that proves the number came down. No fan-swaps. No cosmetic fixes. No vague timelines.

Chesterville homeowners and real-estate professionals choose us because we lead with the three things competitors hide: our license, our timeline, and our price. Here's what separates us from a general handyman with a vent pipe in his truck.

• Ohio License RC202 — verifiable with the Ohio Department of Health. Most competitors bury or omit their license number. We put it on every estimate, every invoice, and every system label.
• Closing-deadline turnaround — when a purchase agreement is on the line, we install on real-estate calendars, not contractor calendars. Most Chesterville installs are scheduled within 5–7 business days, and post-mitigation testing wraps inside the standard 48-hour window.
• Permanent, code-compliant systems — designed to ANSI/AARST RMS-SF 2023 standards with proper pipe diameter, fan sizing, and exterior discharge above the eave line. These pass re-tests. The cheap fan-only jobs don't.
• Transparent flat-rate pricing — most Chesterville single-family homes fall between $1,295 and $1,895 for a complete mitigation system. We quote the number before we show up, not after we're in your basement.
• Multi-vertical credibility — we mitigate radon for Ohio schools, apartment complexes, and commercial buildings under stricter compliance rules. If a school district trusts our work, your basement is straightforward.
• Home inspector referral program — we work directly with Chesterville-area inspectors and real-estate agents to keep closings on schedule. Ask about our Special Offer for referred clients.

Our Chesterville scope of work covers every situation that produces a high radon reading — from a single-family home under a 14-day closing window to a 40-unit apartment building under Ohio Department of Health oversight.

Continuous Radon Monitor (CRM) testing in a sealed-house condition, results in 48 hours, and a written report formatted to satisfy lenders, buyers, sellers, and Ohio disclosure requirements. We test pre-listing, during inspection contingencies, and post-mitigation to verify the system worked.

The gold-standard mitigation method for the slab-on-grade and full-basement homes common around Chesterville and the Route 95 corridor. We core a suction point through the slab, seal cracks and the sump lid, and route Schedule 40 PVC to an exterior radon fan discharging above the roofline. Quiet, permanent, and code-compliant.

Many older Chesterville farmhouses have dirt or partial crawl spaces — a major radon entry path. We install a sealed 12-mil vapor barrier, tie it into the mitigation system, and depressurize the membrane to pull radon out before it reaches the living space.

Ohio law (ORC 3701-69) places radon compliance squarely on the property owner for schools, daycares, and certain multifamily buildings. We design multi-point systems for larger footprints, coordinate with facility managers, and provide the documentation regulators expect.

One of the most common questions we get: will the pipe look ugly on the front of my house? No. We route systems through garages, utility chases, and rear elevations whenever possible. For Chesterville's historic and curb-appeal-sensitive properties, we'll review routing options before we drill.

Speed matters. So does doing it right. Here's exactly how a Chesterville radon mitigation project moves from phone call to passed post-test.

1. Phone consultation & flat-rate quote (Day 1). Tell us your radon test number, your foundation type, and your closing date. We give you a price on the call. No in-home sales pitch required.
2. Site diagnostic & system design (Day 2–3). A licensed RC202 technician evaluates suction points, sub-slab communication, and the cleanest discharge route. We finalize the system design and confirm the install date.
3. Installation (typically a single day). Core drilling, PVC routing, fan installation, sealing of slab penetrations and sump, U-tube manometer mounted, exterior labeling — all to ANSI/AARST standards. Most Chesterville homes are completed in 4–6 hours.
4. Post-mitigation testing (48 hours after install). We deploy a CRM to verify radon levels are below 4.0 pCi/L — almost always below 2.0 pCi/L. You get a written, dated report suitable for buyers, agents, and lenders.
5. Warranty & system documentation. Five-year system warranty, fan manufacturer warranty, and a labeled system that any future buyer's inspector will recognize as professional work.

Chesterville and surrounding Morrow County villages — Mount Gilead, Cardington, Sparta, Marengo — sit on a band of fractured limestone and dolomite bedrock that releases uranium-decay radon gas at higher rates than most of Ohio. According to Ohio Department of Health county data, Morrow County homes average above 4.0 pCi/L on initial tests, putting the area firmly in EPA Zone 1.

What that means on the ground:

• Older homes near the Whetstone Creek floodplain often have stone or block foundations with multiple radon entry paths.
• Newer builds along Township Road 117 and the County Road 26 corridor frequently have passive radon stubs that were never activated — a quick conversion job for our team.
• Farmhouses with attached barns, additions, or partial basements need multi-suction systems, not single-point fixes.
• Homes with sump pumps and drain tile loops are excellent candidates for sub-slab depressurization with sealed sump covers.

We work Chesterville regularly and route from our Akron base through I-71 and US-42 — typical drive-time to a Chesterville job site is under an hour, which is part of how we hold the closing-deadline timeline.
