Radon Eliminator provides Radon Mitigation Ohio OH homeowners, real-estate professionals, school districts, and commercial property owners can defend in writing. We hold Ohio Mitigation License RC202, follow EPA-aligned protocols, and design every system to bring indoor radon below the EPA action level of 4.0 pCi/L — verified by post-mitigation testing, not assumed.

Ohio sits on uranium-rich glacial till and Appalachian shale. The Ohio Department of Health reports that more than 40% of homes tested in some Ohio counties exceed 4.0 pCi/L — among the highest rates in the nation. That's not a marketing line; it's the geology under your foundation. If your inspection report came back at 4.2, 7.8, or 19 pCi/L, you are not an outlier in Ohio. You are the rule.

We exist because most contractors treat real-estate radon work as an inconvenience. We productized it. Call 216-480-9580 and ask about our Closing-Date Radon Service — testing scheduled within 48 hours, mitigation installed inside a single closing window, paperwork your title company will actually accept.

There are radon contractors in Ohio. There is one Ohio radon team built around licensure, deadlines, and documentation. Here is what separates us from the company your neighbor used in 2019.

• Ohio License RC202, stated upfront. Most competitors bury or omit their license number. We lead with it. You should never hire a radon mitigator in Ohio who can't show you a current state license — it's the law, and it's how your post-mitigation report stays defensible at closing.
• EPA-aligned testing protocols. Our continuous radon monitors and short-term tests follow EPA 402-R-92-003 and ANSI/AARST MAH-2019 placement standards. The number on your report is the number a regulator would accept.
• Closing-Date Radon Service. When the deal is on the line, we schedule around your closing — not our route. Test in 48 hours, install in 3–5 business days in most Ohio markets, retest within the EPA-required window.
• Multi-vertical experience. Residential basements, slab-on-grade ranches, crawlspaces, apartment complexes, schools under Ohio EPA scrutiny, and commercial buildings under OSHA general-duty obligations. Most local shops only handle single-family homes.
• Home Inspector Partner Program. Ohio home inspectors who refer radon work get priority scheduling, white-glove client handoffs, and a published partner offer. Ask for details.
• Transparent pricing. Residential mitigation systems in Ohio typically range from $1,295 to $2,495 depending on foundation type, sub-slab communication, and routing. You get a number on the phone — not a sales appointment to find out the number.

Our scope covers every stage of the radon problem — from the first short-term test to the final post-mitigation verification. Every service is performed by an Ohio-licensed technician under RC202.

Short-term and long-term radon testing for Ohio homeowners, plus full sub-slab depressurization system installation. We design around your foundation — full basement, walk-out, crawlspace, slab — and route the discharge stack per ANSI/AARST and Ohio code. Systems include a manometer, sealed sump (if applicable), and a labeled service panel.

Multi-family buildings, schools, daycares, and commercial properties have legal exposure single-family homes do not. We design multi-point sub-slab systems, document airflow at each suction pit, and provide the building owner with a stamped system schematic. Ohio EPA, Ohio Department of Health, and accreditation auditors recognize the format.

48-hour continuous monitor placement, results emailed directly to buyer, seller, and agent in PDF form. We understand the FHA, VA, and conventional radon contingency language. If the result is over 4.0 pCi/L, we can quote mitigation the same day and start before closing.

Every system we install includes a follow-up radon test 24 hours to 30 days after activation, per EPA protocol. You receive a written report showing the new pCi/L level. This is the document title companies, lenders, and future buyers will ask for.

Inherited a system from a previous owner? We diagnose failed fans, cracked manometers, undersized suction points, and improper discharge routing. Many 10–15 year old Ohio systems were undersized for today's tighter homes. We upgrade rather than replace whenever possible.

A clean install starts with a clean diagnostic. We do not guess at suction point locations or fan sizing. Here is exactly how an Ohio mitigation job runs from first call to final report.

1. Phone consultation and quote (same day). Tell us your foundation type, the current radon reading, and your timeline. You get a price range on the call.
2. On-site diagnostic. We perform a sub-slab communication test, identify the optimal suction point, and confirm fan sizing. For commercial and school work, we map multi-point requirements.
3. System installation. Most residential systems install in 4–8 hours. We core the slab, seal the system, route PVC to code (typically through the rim joist and up the exterior, or interior through unconditioned space), install the rated fan above the living space, and mount the manometer.
4. Activation and short-term retest. The system is energized and a continuous monitor is placed for the post-mitigation verification test.
5. Documented results. You receive the final pCi/L reading, system warranty, and Ohio license documentation in a single PDF — closing-ready.

Ohio's radon problem isn't uniform. The geology shifts under your feet between Lake Erie and the Ohio River, and a mitigation system that works in a Westlake basement won't perform the same way in a Cincinnati slab.

We work across the entire state with established crews serving Akron, Cleveland, Canton, Columbus, Cincinnati, Dayton, Toledo, Youngstown, and the surrounding suburbs. Counties like Stark, Summit, Cuyahoga, Hamilton, Franklin, and Montgomery consistently produce the highest residential readings we see — sometimes 10x the EPA action level in older homes with block foundations.

Northeast Ohio's glacial outwash creates highly permeable sub-slab conditions — great for sub-slab depressurization, often allowing a single suction point to mitigate an entire footprint. Southern Ohio's denser clay soils sometimes require larger fans or additional suction pits. We size the system to the soil under your specific address, not to a one-size template.

Our team also handles work for Ohio school districts subject to indoor air quality scrutiny, apartment portfolio owners in Columbus and Cleveland metros, and home inspectors from Akron to Dublin who need a reliable referral partner. If your property is in Ohio, we are the call.

We publish ranges because Ohio homeowners are tired of being baited with a low number and surprised at the door. These are real 2024 numbers for the work we do.

• Standard residential sub-slab system (basement or slab): $1,295 – $1,795
• Crawlspace encapsulation + sub-membrane depressurization: $1,895 – $2,995
• Multi-point residential (large or complex foundations): $1,995 – $2,495
• Short-term real-estate radon test (continuous monitor): $145 – $195
• Post-mitigation verification test: Included with every system we install
• Commercial, apartment, and school systems: Quoted on-site after sub-slab communication testing

Every system carries a workmanship warranty and a manufacturer warranty on the radon fan (typically 5 years). Financing is available for qualified Ohio homeowners.
