Radon Eliminator is an Ohio-licensed radon mitigation contractor (Ohio Mitigation License RC202) serving Tiffin, Fostoria, Bascom, Republic, and the rest of Seneca County. We design and install permanent sub-slab depressurization systems engineered to the EPA's mitigation standards and the Ohio Department of Health's rules under OAC 3701-69.

Tiffin homeowners typically call us for one of three reasons: a real-estate inspection came back above 4.0 pCi/L and closing is days away, a long-term test confirmed elevated radon in a basement where the kids sleep, or a commercial or school property needs documented compliance. We handle all three — and we lead with our license number because in Ohio, you legally cannot install a mitigation system without one.

Our service area covers every neighborhood in Tiffin, from the older homes near Heidelberg University and Tiffin University to newer builds along West Market Street, Hopewell-Loudon district properties, and rural parcels off SR-18 and US-224. We've seen what radon does in glacial-till soils across north-central Ohio, and we engineer each system to the structure in front of us.

Most local radon shops bury their license number, dodge real-estate deadlines, and refuse to give a firm price over the phone. We do the opposite. Here is what separates the best Radon Mitigation Tiffin property owners can hire:

• Ohio License RC202, stated upfront. Verify it with the Ohio Department of Health before you hire anyone — including us.
• Closing-Date Radon Service. If your purchase agreement has a deadline, we work to it. Testing, mitigation, and post-mitigation verification scheduled around your closing — not our convenience.
• Multi-vertical experience. Single-family homes, apartment complexes, condos, schools, daycares, and commercial buildings. Most Tiffin-area radon contractors only handle houses. We're the call when the property is bigger or the liability is higher.
• Flat, documented pricing. Most Tiffin homes fall in the $1,150–$1,850 range for a standard sub-slab depressurization system. We quote in writing before we start. No surprises.
• Post-mitigation testing included. We don't leave until a follow-up test confirms you're under the EPA action level of 4.0 pCi/L — and we hand you the report.
• System warranty + workmanship guarantee. Fans carry a 5-year manufacturer warranty; our installation work is guaranteed for the life of the system at your address.

That's why agents at Re/Max, Howard Hanna, and the local independents in Tiffin keep our number in their phones — and why home inspectors refer us through our partner program.

We deliver the full radon scope — from the first short-term test to a verified, code-compliant system. These are the professional Radon Mitigation Tiffin OH services we run every week:

Continuous radon monitors placed per EPA closed-building conditions, results in 48 hours, signed report acceptable for any Tiffin-area real-estate transaction. Required before mitigation and required again after.

Active sub-slab depressurization (ASD) is the gold standard for Tiffin's typical poured-concrete and block-foundation basements. We core the slab, run sealed 3" or 4" PVC up through the attic or along an exterior chase, mount a rated radon fan (Radon Away RP145, GP501, or HP2200 depending on diagnostics), and discharge above the eave per EPA standards. Crawl spaces get sub-membrane depressurization.

Multi-family buildings, Seneca County schools, daycares, and commercial buildings on Madison Street and the Tiffin industrial corridor require engineered multi-point systems and ANSI/AARST CC-1000 compliant design. We handle the diagnostics, the permits, and the post-mitigation verification across every wing.

Bought a Tiffin home with an existing system that may have been DIY'd? We pressure-test, inspect manometers, check fan amperage, verify discharge location, and bring non-compliant systems up to current Ohio code.

Every install includes a follow-up short-term test 24 hours to 30 days after activation. You get a documented pCi/L number under 4.0 — and the paperwork your buyer, lender, or compliance officer needs.

This is exactly how a job runs from first call to final report:

1. Phone consultation and quote (same day). Tell us the test result, the foundation type, and your timeline. We give you a price range over the phone and a firm written quote after we see photos or visit.
2. On-site diagnostic and design. We inspect the foundation, identify suction points, check for tight fill or stem walls, and engineer the system. Most Tiffin homes need one suction point; larger or sectioned basements may need two.
3. Installation (typically one day). A two-person crew installs the system in 4–8 hours. Slab is sealed, pipe is run, fan is mounted, electrical is tied in by a licensed electrician, and a system label and manometer are installed at the access point.
4. Post-mitigation test and documentation. We deploy a continuous radon monitor, retrieve it 48 hours later, and email you the report showing your home is below 4.0 pCi/L. If it isn't — which is rare — we modify the system at no charge.

Ohio has one of the highest average indoor radon levels in the United States, and Seneca County is squarely inside EPA Radon Zone 1 — the highest risk tier, with predicted average indoor screening levels above 4.0 pCi/L. According to Ohio Department of Health data, roughly 1 in 3 Ohio homes tested shows elevated radon, and Seneca County's glacial-till and limestone bedrock geology pushes that rate higher in many Tiffin neighborhoods.

We've mitigated homes throughout Tiffin: century homes near Frost-Kalnow Park, ranches along Coe Street, two-stories in the Heritage Hills area, properties near Hedges-Boyer Park, and rural farmhouses outside the city limits toward Bloomville and New Riegel. Each has a different foundation profile — fieldstone, block, poured concrete, slab-on-grade — and each requires a different suction strategy. A national chain reading off a script can't do that. A licensed Ohio contractor who has spent years under Seneca County basements can.

We also serve the surrounding region for property owners with portfolios across north-central Ohio — Findlay, Fostoria, Bucyrus, Fremont, Sandusky, and out to Mansfield. If you own multiple buildings, ask about volume pricing.

Tired of getting the runaround on cost? Here's the honest range for affordable Radon Mitigation Tiffin property owners can expect:

• Standard residential sub-slab system (single suction point): $1,150 – $1,550
• Complex residential (multiple suction points, crawl space, or exterior routing): $1,550 – $2,400
• Short-term radon test with documented report: $150 – $195
• Post-mitigation verification test: Included with every install
• Commercial / multi-family / school: Quoted after site walk — typically $0.40–$1.20 per sq ft of slab depending on design
