If your inspection report came back at 4.2, 7.8, or 22 pCi/L, you need two things: a straight answer and a fast fix. Radon Eliminator delivers both. We are an Ohio-licensed radon mitigation contractor (Ohio Mitigation License RC202) serving Big Spring and the surrounding Logan County area with EPA-aligned testing protocols and permanent sub-slab depressurization systems engineered to bring your home below the EPA action level of 4.0 pCi/L.

Most homeowners in Big Spring searching for Radon Mitigation Big Spring OH are doing it on a deadline — a real-estate closing, a school board mandate, or a property manager's compliance review. We built our company around that reality. We answer the phone, we quote in writing, and we schedule installs in days, not weeks.

Call (330) 366-9000 for a same-day quote, or request a written estimate online. No sales pressure, no fan-only "band-aid" fixes — just a documented system that drops your radon level and stays there.

• License: Ohio Radon Mitigation Specialist RC202
• Standards: EPA-aligned protocols, ANSI/AARST-compliant installations
• Guarantee: Post-mitigation radon level under 4.0 pCi/L — documented
• Speed: Closing-date service for real-estate transactions
• Coverage: Residential, commercial, schools, multi-family across Ohio

There are plenty of contractors who will sell you a fan and a PVC pipe. There are very few who will hand you their Ohio license number, a written scope, and a post-mitigation test result you can take to the closing table. That difference matters when the deal — or your family's lungs — is on the line.

Ohio License RC202 Stated Upfront

Ohio requires licensure to install radon mitigation systems. We lead with our license number, RC202, on every quote and every invoice. If a competitor won't put their Ohio radon license in writing, that's your answer.

Real-Estate Deadline Specialists

We productized closing-date radon work because we got tired of watching deals die over a 4.1 pCi/L reading. Our Closing-Date Radon Service coordinates testing, mitigation, and post-mitigation verification around your closing date — not our crew's convenience. Buyers, sellers, listing agents, and home inspectors across Big Spring rely on us when the contingency clock is running.

Multi-Vertical Experience

Single-family homes in Big Spring neighborhoods. 80-unit apartment complexes in Bellefontaine. Elementary schools across Logan and Champaign counties. Office buildings near US-68. We are one of the few Ohio radon firms with documented mitigation experience across all four verticals, which matters when your property has a slab-on-grade design, multiple sumps, or a complex HVAC interaction.

Transparent, Written Pricing

You will get a flat-rate quote in writing before any work begins. Most single-family Radon Mitigation Big Spring projects fall between $1,295 and $1,895 depending on foundation type, system routing, and electrical access. Commercial and multi-family projects are scoped on-site. No surprise add-ons.

Documented Results, Not Promises

Every install includes post-mitigation testing. You receive a written report showing the pre- and post-mitigation pCi/L readings, the system specs, the warranty, and the maintenance schedule. That document goes straight into your real-estate file, your school district records, or your property management binder.

Radon Eliminator handles the full radon lifecycle — from the first 48-hour test through the final post-mitigation verification. Our Big Spring service menu includes:

Residential Radon Testing

Short-term continuous radon monitor (CRM) testing for real-estate transactions, typically 48 hours, with results delivered as a sealed PDF report. We also handle long-term alpha-track testing for homeowners who want a multi-month baseline before deciding on mitigation.

Residential Radon Mitigation System Installation

Active sub-slab depressurization (ASD) is the gold standard for Big Spring's clay-heavy soils and predominantly basement and crawlspace foundations. We engineer the suction-point placement, seal slab penetrations, route schedule-40 PVC through the least-intrusive path, install an EPA-rated radon fan, and add a U-tube manometer for ongoing performance verification.

Commercial & Multi-Family Mitigation

Apartment complexes, office buildings, retail centers, and mixed-use properties in the Big Spring corridor require multi-point ASD designs, often with multiple fans and balanced suction zones. We provide engineered drawings, code-compliant installs, and unit-by-unit post-mitigation testing.

Radon Mitigation for Schools

Ohio schools have a public-health responsibility to maintain radon levels below the action threshold. We work with school districts and facilities directors on classroom-by-classroom testing, summer-break mitigation scheduling, and documented compliance reporting.

Existing System Inspection & Upgrade

If your home already has a radon system but levels are still elevated — or the fan is humming louder than your refrigerator — we diagnose the issue, replace failed fans, reseal slab joints, and re-engineer suction points. Many "existing" systems we inspect in Big Spring were installed before current ANSI/AARST standards and need updating.

Post-Mitigation Testing & Verification

Every install is followed by a 48-hour CRM test to confirm the system has reduced radon below 4.0 pCi/L. Results are documented and delivered in writing — closing-ready.

24/7 On-Site Radon Consultation

When a deal is at risk, we travel. On-site radon assessment and emergency consultation is available across Ohio, including Big Spring, West Liberty, Bellefontaine, and surrounding communities.

Every project follows the same disciplined sequence. No improvisation, no shortcuts.

Step 1: Diagnostic Site Visit

A licensed RC202 technician inspects your foundation, identifies slab penetrations and sump configurations, evaluates HVAC interaction, and chooses the optimal suction-point location. This is where bad installs are born — we don't skip it.

Step 2: Written Scope & Flat-Rate Quote

You receive a written scope including system type, pipe routing, fan model, electrical work, exterior penetration, and warranty terms. The price is flat. If conditions change mid-install, we tell you before we proceed.

Step 3: Code-Compliant Installation

Most single-family installs take 4–6 hours. We core the slab, seal joints with polyurethane, route schedule-40 PVC through the path that preserves your home's appearance, mount the radon fan in an unconditioned space (per code), and wire it to a dedicated circuit when required.

Step 4: 48-Hour Post-Mitigation Test

A continuous radon monitor is placed in the lowest livable area. After 48 hours of closed-house conditions, we collect the data and issue your post-mitigation report — the document that closes the deal.

Step 5: System Documentation & Warranty Handoff

You receive the test report, system spec sheet, fan warranty (typically 5 years), workmanship warranty, and a one-page maintenance guide. That packet is what real-estate attorneys, school boards, and property managers actually need on file.

Big Spring sits in a region of Ohio with documented elevated radon potential. The EPA Map of Radon Zones places much of west-central Ohio — including Logan, Champaign, and Hardin counties — in Zone 1, the highest-risk category with predicted indoor average levels above 4.0 pCi/L. That isn't marketing; that's geology. The glacial till and limestone bedrock under this part of the state release radon at higher concentrations than in much of the country.

What that means for Big Spring homeowners: a single "clean" test from a neighbor's house tells you nothing about your home. We routinely see two houses on the same street test at 1.8 pCi/L and 11.4 pCi/L. Foundation type, sump configuration, slab condition, and HVAC behavior all shift the number dramatically.

We serve homeowners and property managers throughout the Big Spring area, including West Liberty, Bellefontaine, DeGraff, Quincy, Zanesfield, and the broader US-33 and US-68 corridors. Our crews routinely work near Indian Lake, around Mad River Mountain, and across the rural townships where older farmhouses with stone foundations and partial basements present some of the trickiest mitigation puzzles in the state.

If you're a Big Spring real-estate agent, home inspector, or property manager, we have a referral program with published terms — not a vague "we'll take care of you" handshake. Ask about our home-inspector partner program when you call.
