Radon Eliminator provides Radon Mitigation Holmes OH homeowners, real-estate agents, school districts, and apartment owners can rely on when the result has to be defensible in writing. We are a fully licensed Ohio radon mitigation contractor — Ohio Mitigation License RC202 — and every system we install is engineered to the EPA's active soil depressurization standard with a post-mitigation reading below the 4.0 pCi/L action level.

Holmes County and the broader Amish Country region sit in EPA Radon Zone 1, the highest-risk classification in the country. The fractured limestone and shale bedrock under Millersburg, Berlin, Walnut Creek, Sugarcreek, and Killbuck creates natural pathways for radon gas to enter basements, crawl spaces, and slab-on-grade homes. Ohio Department of Health county data shows average indoor radon readings in Holmes County routinely exceed the national average, with many homes testing between 4 and 10 pCi/L — and a meaningful percentage above 20.

If you just received an inspection report flagging elevated radon and you're scheduled to close in two weeks, call us first. We productize closing-date jobs. We don't bury you in voicemail.

Most Ohio radon companies won't lead with their license number. We do. Ohio Mitigation License RC202 is published on every quote, every invoice, and every system label we install. That license is what makes a mitigation system legally defensible in a real-estate transaction, a school board audit, or an apartment habitability complaint.

• Licensed Ohio radon professionals (RC202) — not a handyman with a fan, not a roofer with a sideline.
• EPA-aligned protocols — testing follows ANSI/AARST MAH-2019 and MS-PC 2015 standards; mitigation follows SGM-SF 2017.
• Closing-Date Radon Service — testing in 48 hours, mitigation install in 3–7 days, documented post-mitigation result in writing before your closing.
• Multi-vertical experience — single-family homes, commercial buildings, schools, and apartment complexes across Holmes, Wayne, Tuscarawas, and Coshocton counties.
• Home-inspector partner program — published referral terms, no hidden splits, fast turnaround that protects the inspector's reputation.
• Workmanship warranty and a guaranteed post-mitigation reading under 4.0 pCi/L — or we adjust the system at no cost.

We're the team realtors in Holmes, Wayne, and Tuscarawas counties call when the deal is on the line and the seller's other contractor stopped returning calls.

We deliver a complete scope of professional Radon Mitigation Holmes OH property owners need — from initial short-term testing through long-term system verification.

The standard installation in a Holmes County home is an active sub-slab depressurization (ASD) system: a sealed suction point through the basement slab, a sealed PVC vent stack routed up through the structure or along the exterior, and a continuously running radon fan rated for the soil conditions under your home. For homes on crawl spaces — common in older farmhouses near Berlin and Charm — we install a sub-membrane depressurization system with sealed 6-mil or 10-mil polyethylene. Every system includes a U-tube manometer, a system label with our RC202 license, and a written post-mitigation test.

Ohio law treats schools, licensed childcare facilities, and multi-family rental properties differently than single-family homes. We design and install multi-point depressurization systems for slab-on-grade commercial buildings, multi-zone apartment complexes, and school district facilities. We coordinate with facility managers, school boards, and property management to schedule work around occupied hours and to deliver the documentation an Ohio Department of Health audit requires.

We deploy continuous radon monitors (CRMs) for 48-hour real-estate transaction tests and charcoal or alpha-track devices for longer 90-day or annual assessments. CRM data is tamper-resistant and hour-by-hour — exactly what a buyer's agent or relocation company expects to see. Results are emailed in PDF within 24 hours of pickup.

Every mitigation install includes a follow-up test 24–48 hours after the fan has been running. We do not consider a job complete until the documented reading is below 4.0 pCi/L. If the first test doesn't hit, we return at no charge to add a suction point or upgrade the fan.

Bought a home in Millersburg with a system already installed? We inspect existing systems for code compliance, manometer pressure, fan condition, sealing integrity, and discharge point. Many systems installed before 2015 in Holmes County do not meet current ANSI/AARST standards. We provide a written evaluation and an upgrade quote.

1. Diagnostic Visit and Quote (Day 1). We measure your foundation, identify the slab type, locate utilities, and design the suction-point layout. You receive a fixed written quote — not a range, not a 'starting at.'
2. Permit and Scheduling (Day 1–3). We pull any required local permits in Holmes County and lock your install date. Real-estate deadlines get priority scheduling.
3. System Installation (Day 3–7, typically 4–8 hours on site). We core the slab, install the suction pit, seal all penetrations, route the vent stack, mount the fan above the living area or on the exterior, wire it on a dedicated circuit, and install the manometer.
4. Post-Mitigation Test (24–48 hours later). A continuous radon monitor is placed in the lowest livable area. We retrieve it, generate the PDF report, and email the documented result.
5. Documentation and Warranty Registration. You receive the system diagram, the RC202 license number, the post-mitigation test, the fan warranty, and our workmanship warranty — the full package a closing attorney or a school board needs.

We work across Holmes County constantly — Millersburg, Berlin, Walnut Creek, Sugarcreek, Charm, Mount Hope, Killbuck, Nashville, Glenmont, and Big Prairie. We know the geology under Route 39 and Route 62. We know the older limestone foundations in the Amish Country tourist corridor behind Heini's and Lehman's. We know the newer slab-on-grade builds going up around Berlin Heights and the rental cabins around Lake Buckhorn.

That geology matters. Homes built into the hillsides off County Road 70 frequently test high because of the rock-fissure pathways under their basements. New construction near Mt. Hope often shows elevated readings because of the disturbed soil during site work. Crawl-space cabins around the Mohican area need sub-membrane systems, not slab systems. We've installed in all of them.

We also serve the surrounding counties — Wayne (Wooster, Orrville), Tuscarawas (New Philadelphia, Dover, Sugarcreek), Coshocton, and Ashland — and our Akron base lets us respond to Holmes County closing-date emergencies within 24–48 hours.

We publish clear pricing because vague quotes are how homeowners get burned.
