If your home in Cairo just tested above 4.0 pCi/L, you have a problem with a clear, fixable solution — and a timeline. Radon Eliminator is Ohio's licensed radon mitigation contractor (Ohio Mitigation License RC202) serving Cairo, Allen County, and the surrounding Lima region with EPA-aligned radon testing and permanent, code-compliant mitigation systems.

Ohio has one of the highest radon exposure profiles in the United States. The geology under Allen County — fractured limestone and glacial till — pushes radon gas through foundation cracks, sump pits, and crawlspace soil into the homes above. In Cairo specifically, where many properties sit on older basements and slab-on-grade builds from the mid-20th century, elevated radon is common and rarely visible without testing.

Radon Mitigation Cairo OH isn't a luxury upgrade. It's the engineered fix that brings your home back under the EPA action level and, in the middle of a real-estate transaction, keeps your closing on the calendar. Call (800) 727-0683 for same-week scheduling.

Cairo homeowners and agents have options — but most local contractors won't lead with their license number, won't commit to a closing date, and won't service the commercial buildings, apartment complexes, or schools that need this work just as urgently. We do.

• Ohio License RC202 — stated upfront, on every estimate, every invoice, every system tag. Most competitors bury or omit it.
• Closing-Date Radon Service — a productized track for real-estate deadlines. Testing scheduled within 48 hours, mitigation installed inside the inspection contingency window, post-mitigation results delivered before your closing date.
• EPA-aligned protocols — continuous radon monitors, 48-hour minimum test cycles, and documentation that survives lender and attorney review.
• Multi-vertical capability — single-family homes in Cairo, multi-unit apartments across Lima, school buildings in Allen County, and commercial properties statewide. One licensed team, not three subcontractors.
• Transparent, written pricing — most Cairo homes mitigate in the $1,200–$2,200 range. You get the number before we start, not after.
• Post-mitigation guarantee — your system will hold readings under 4.0 pCi/L, documented with a follow-up test. That's the deliverable.

We're the team Cairo home inspectors refer to when they flag elevated radon on a report — because the inspector's reputation rides on whether the fix actually works.

Every Cairo property is different. Soil type, foundation, basement layout, and HVAC behavior all change the system design. Here's the work we do, day in and day out.

The gold-standard mitigation method for Cairo basements and slab homes. We core through the slab, install a sealed suction pit, route schedule-40 PVC through a conditioned chase, and mount a code-rated radon fan above the living envelope. The system runs continuously, pulls radon out from under the foundation, and vents it above the roofline per ANSI/AARST standards.

Many older Cairo farmhouses and ranches have exposed dirt crawlspaces — the single biggest radon entry point in this part of Ohio. We install a sealed, reinforced vapor barrier across the soil, tie it into the foundation walls, and depressurize beneath it. Bonus: you also stop moisture, mold spores, and pest pressure.

You're 14 days from closing and the inspection report flagged radon at 6.8 pCi/L. We've run this play hundreds of times. EPA-aligned 48-hour test, mitigation installed within 3–5 business days, post-mitigation clearance test completed before your closing date. Documentation is delivered in a format your title company and lender will accept without questions.

Ohio property owners are legally responsible for radon levels in occupied buildings. We design and install multi-point mitigation systems for Cairo-area apartment complexes, commercial offices, daycares, and school facilities. Engineered drawings, licensed install, and compliance-grade documentation included. This is a vertical most local radon shops won't touch — we built our practice around it.

The number on the test is the deliverable. After installation, we run a continuous radon monitor for a minimum of 48 hours, deliver a written report, and confirm the system has brought levels below 4.0 pCi/L. If it hasn't, we adjust the system at no charge until it does.

There's no mystery to good radon work. There's only doing it correctly, on schedule, with the right materials and the right license. Here's how a typical Cairo project runs.

1. On-site diagnostic visit (Day 1). Our licensed technician walks the property, identifies foundation type, locates sump pits, drain tile, slab penetrations, and HVAC interactions. You receive a written estimate before we leave — no follow-up phone tag.
2. System design and permit (Day 1–2). We design the suction-point layout, fan sizing, and vent routing to AARST standards. If your project requires permits (commercial and multifamily typically do), we pull them.
3. Installation (Day 3–5). Most single-family Cairo installs are completed in 4–6 hours, single-day. Commercial and multi-unit jobs follow a phased schedule we publish in advance.
4. Post-mitigation testing (Day 5–8). Continuous monitor placed for 48+ hours. Written report delivered with your final invoice.
5. Transferable warranty and documentation. Your system warranty, license number, and test results are bundled into a single PDF — exactly what real-estate attorneys and future buyers will ask for.

Cairo sits in northern Allen County along OH-696, surrounded by the agricultural belt between Lima, Bluffton, and Columbus Grove. The radon picture here is shaped by three things: glacial outwash soils with high permeability, fractured carbonate bedrock underneath, and a housing stock that skews toward basement foundations built before modern radon-resistant construction (RRNC) codes.

We regularly mitigate homes near the village center off South Main Street, properties along Sugar Creek Road, and rural acreage stretching toward Beaverdam and Bluffton. We also work commercial properties along OH-235 and serve apartment owners throughout the Lima metro. Our Akron headquarters lets us deploy a licensed crew across Allen County typically within 48–72 hours of your call.

For context: the EPA estimates that roughly 1 in 15 U.S. homes has elevated radon. In Ohio, and specifically in counties like Allen with our soil and bedrock profile, that ratio is meaningfully higher. If you haven't tested, you don't know — and if you tested above 4.0 pCi/L, the next step is mitigation, not a second opinion.

We also serve nearby Ohio markets including Columbus, Cleveland, Canton, and Akron — same license, same process, same guarantee.

We publish ranges because the work deserves transparency. Final price depends on foundation type, fan size, vent routing, and finished-space considerations.

• Standard basement ASD system: $1,200 – $1,800
• Slab-on-grade home: $1,400 – $2,000
• Crawlspace sub-membrane system: $1,800 – $2,800
• Multi-suction or hybrid system: $2,200 – $3,500
• Pre-purchase radon test (real-estate): $150 – $200
• Post-mitigation clearance test: Included with every install

Financing is available. Real-estate closings can be paid at closing via attorney escrow. Inspector and agent partner rates are published in our referral program.
