Radon Mitigation Cincinnati OH | RC202 Licensed Pros

Hamilton County is classified by the EPA as a Zone 1 radon area — the highest risk tier in the country, with predicted indoor averages above 4.0 pCi/L. That's not marketing copy; it's the reason your inspector tested in the first place. Cincinnati's limestone bedrock, clay soils, and high water table push radon gas straight into basements from Hyde Park to Anderson Township to West Chester.

If your test came back at 4.2, 5.8, or even 12 pCi/L, you don't have an unusual house — you have a Cincinnati house. Radon Mitigation Cincinnati OH work is what we do every day, and the fix is mechanical, permanent, and predictable. Radon Eliminator is an Ohio-licensed radon contractor (Ohio Mitigation License RC202) that installs sub-slab depressurization systems engineered to drop your levels below the EPA action level of 4.0 pCi/L — and keep them there.

We serve homeowners, buyers, sellers, REALTORS®, home inspectors, and commercial property owners across Cincinnati, Norwood, Blue Ash, Mason, Loveland, Montgomery, Indian Hill, Mariemont, Madeira, Sharonville, and the Northern Kentucky border communities. Call (xxx) xxx-xxxx for same-week scheduling.

There are two kinds of radon contractors in the Cincinnati market: the ones who swap a fan and hope the re-test passes, and the ones who engineer a system that lasts 20 years. We're the second kind. Here's what separates Radon Eliminator from the rest:

• Ohio License RC202 — Our mitigation license number is published, verifiable through the Ohio Department of Health, and on every permit. Most competitor websites bury or omit theirs.
• Closing-deadline turnaround — We schedule around your purchase agreement, not our calendar. Testing in 48 hours, install typically within 5–7 business days of contract.
• Flat, written pricing — No surprise change orders. Standard Cincinnati basement mitigation typically runs $1,195–$1,795 depending on slab condition and routing.
• Permanent, code-compliant systems — Sealed sumps, manometers, exterior routing, and fan housings sized to your home's CFM — not a generic kit pulled off a shelf.
• Multi-vertical credibility — We mitigate Cincinnati-area schools, apartment buildings, and commercial properties. The same crew and the same standards show up at your house.
• Post-mitigation re-test included — You get documented proof of sub-4.0 pCi/L levels for your buyer, lender, or disclosure file.

That's why home inspectors and REALTORS® across Greater Cincinnati refer their clients to us by name.

Whether you're staring at a high test result on a kitchen counter or managing a 200-unit apartment portfolio, we have a defined service for it.

Continuous radon monitors and charcoal canister protocols that meet ANSI/AARST MAH-2019 standards. Test placement, duration, and reporting all match what your buyer's agent, lender, and the Ohio Department of Health expect. Results emailed as a signed PDF — ideal for real-estate transactions on a closing clock.

The gold standard for Cincinnati basements, crawl spaces, and slab-on-grade homes. We core the slab, install sealed suction points, route 3" or 4" Schedule 40 PVC through a discreet path (we'll show you the route before we drill), and install an inline radon fan rated for your home's airflow. Every system includes a U-tube manometer, electrical disconnect, labeling per Ohio code, and exterior discharge above the roofline.

Older homes in Clifton, Northside, and Mt. Lookout often have dirt or partial crawl spaces that leak radon at much higher rates than poured basements. We install a 12-mil reinforced vapor barrier, seal seams and penetrations, and tie the membrane into a sub-membrane depressurization system. One visit, one crew.

Ohio law holds commercial property owners, school districts, and apartment operators responsible for safe indoor radon levels. We design multi-point, multi-fan systems for buildings up to 100,000+ sq ft, coordinate with facility managers, and provide the documentation your insurer and the ODH require. If schools trust us with classrooms full of kids, your basement is a straightforward job.

We run a named referral lane for Cincinnati-area inspectors and agents. Priority scheduling, direct communication with your client, a dedicated point of contact, and a transaction-friendly closeout package. Ask about our current Special Offer when you call.

Radon is a solvable problem. Here's exactly how we solve it on a Cincinnati timeline:

An RC202-licensed technician walks the basement, sub-slab area, and exterior. We identify suction point locations, check for slab cracks and open sumps, and choose a routing path that's both effective and visually clean — no ugly pipe across the front of your house unless it's the only structural option, and we'll tell you up front if it is.

You get a written proposal with the exact system design, fan model, routing diagram, and total price before any work begins. Most Cincinnati single-family installs are quoted between $1,195 and $1,795.

Most systems are installed in 4–6 hours. We core the slab, seal the suction point, run PVC, mount the fan outside or in an attic per AARST standards, wire the manometer, and clean up. Your home is usable that night.

48–72 hours after install, we deploy a continuous monitor to verify levels are below 4.0 pCi/L. You receive a signed report suitable for buyers, lenders, and Ohio disclosure forms — plus a 5-year workmanship warranty and a manufacturer fan warranty up to 7 years.

We've installed systems in nearly every Cincinnati ZIP code, and the geology changes meaningfully from one neighborhood to the next. Homes in Hyde Park, Oakley, and Mt. Lookout tend to be older brick foundations on clay — they often need crack sealing plus a single suction point. Anderson Township, Mason, and West Chester have newer poured basements where one well-placed suction point under the slab almost always handles the job. Indian Hill and Terrace Park properties frequently include finished basements, walkouts, and additions — these often require dual suction points, which we'll identify on the diagnostic visit.

We also handle properties near the Little Miami River corridor, the Mill Creek valley, and across the river in Northern Kentucky (Fort Mitchell, Crescent Springs, Edgewood). If you're closing on a home anywhere from Loveland to Cleves, we can get there.
