You got the inspection report. The number is above 4.0 pCi/L. Maybe it's 5.2, maybe it's 8.7, maybe it's a number that made your real-estate agent quietly sigh on the phone. Either way, the closing date doesn't move — so the radon problem has to.

Radon Eliminator is Ohio's licensed radon authority (Ohio Mitigation License RC202) handling Radon Mitigation Dinsmore OH property owners need when the clock is ticking. We install permanent, EPA-aligned, code-compliant active soil depressurization systems that pass the post-mitigation re-test the first time. No fan-swap shortcuts. No vague timelines. No surprise change orders the day of install.

We work across Auglaize County and the surrounding Dinsmore area for residential sales, commercial buildings, multi-family apartments, and school districts. If a school board trusts us with a building full of kids, your basement is a straightforward day's work.

• RC202 Ohio Licensed — full state mitigation credentials, not a handyman with a fan
• Closing-deadline turnaround — most Dinsmore installs scheduled within 48–72 hours of acceptance
• Transparent flat pricing — typical residential systems $1,150–$1,750, quoted before we arrive
• Post-mitigation re-test included — written documentation for the buyer, seller, lender, and title company

Most radon contractors are HVAC guys with a side hustle. We aren't. Radon is what we do — every day, only in Ohio, only by licensed professionals. That focus is the reason Dinsmore real-estate agents, home inspectors, and property managers keep our number saved.

Ohio law (ORC 3723) requires anyone installing a residential radon mitigation system to hold a current state mitigation license. A lot of competitors don't display theirs because they don't have one, or they're using a 'sub' relationship to skirt the requirement. Our license number is RC202. Verify it on the Ohio Department of Health radon program registry before you hire anyone — including us.

When a Dinsmore listing fails a radon test, you typically have 5–10 business days inside the inspection contingency window to remediate and re-test. We schedule mitigation installs within 48–72 hours and complete post-mitigation testing within 48 hours after activation. That's a full close-to-clear cycle in under a week — fast enough to keep the deal alive without the buyer's lender getting nervous.

We mitigate radon in Ohio public schools, multi-family apartment complexes, day cares, assisted-living facilities, and commercial office buildings. Those projects require sealed permits, sub-slab testing grids, and signed-off engineering. A single-family Dinsmore basement install is, by comparison, a quiet Tuesday morning.

We offer priority scheduling for your transactions, co-branded post-mitigation reports for your client files, and a standing Special Offer on testing rates for repeat referral partners.

Every Dinsmore property is a little different — a 1970s ranch with a poured slab behaves differently than a new build in a development with crawlspace sections. We design the system to the home, not the other way around.

We run continuous radon monitor (CRM) tests for real-estate transactions — 48-hour closed-house protocol, tamper-resistant, court-admissible results. We also handle short-term charcoal kits for diagnostic checks and long-term alpha-track testing for property owners who want a yearly average. Results are emailed in PDF, formatted for lender and buyer review.

This is the EPA-recommended standard and the system we install on roughly 95% of Dinsmore homes. A sealed PVC pipe is routed from beneath the slab through a continuously-running radon fan, venting above the roofline. Properly designed, ASD pulls radon out of the soil before it ever enters living space. Typical reductions: 85–99%.

Plenty of older Dinsmore homes have partial or full crawlspaces. We install heavy 12-mil reinforced vapor barrier, seal it to the perimeter, and tie it into the mitigation fan. This doubles as a moisture-control upgrade — a feature listing agents often highlight on the MLS.

The number-one complaint about radon systems is the ugly white pipe running up the front of the house. We route through the garage, utility chase, or interior closet whenever the structure allows, and exit through the roof — not the front facade. On exterior runs we paint-match the siding at no extra charge.

For Dinsmore-area commercial properties, apartment complexes, and educational facilities, we provide sub-slab communication testing, engineered multi-point systems, sealed permits, and ANSI/AARST-CCAH compliant documentation. Property owners have a legal duty of care under Ohio's radon disclosure framework — we deliver the paperwork that proves you met it.

Here's exactly what happens from the phone call to the final re-test certificate.

Call (330) 836-1934. We'll ask about your foundation type, square footage, the radon reading from your inspection, and the closing date if there is one. You get a flat-rate quote on that call — not a vague range.

Our licensed technician walks the Dinsmore property, evaluates sub-slab communication, identifies the optimal suction point, and confirms the routing plan with you in person. No surprises on install day.

Installation takes 4–8 hours depending on routing complexity. We core a single suction point through the slab, run sealed schedule-40 PVC, install the mitigation fan (Radon Away GP501 or RP-series, model selected by static pressure), wire the warning manometer, and finalize the roof penetration with a properly flashed boot.

We deploy a continuous radon monitor for a 48-hour test starting 24 hours after system activation. Per EPA protocol, this confirms the system is working before we hand off the report.

You receive a PDF report with the pre-mitigation reading, post-mitigation reading, system schematic, license documentation, and warranty paperwork. Forwardable directly to buyer, seller, agent, lender, and title.

Dinsmore sits in western Ohio's Auglaize County, near St. Marys and Wapakoneta — a region the EPA classifies in elevated radon risk zones. The underlying geology includes glacial till over limestone and Ohio shale, both of which release radon gas as uranium decays naturally in the soil. That gas migrates upward and accumulates in the lowest level of homes, especially during winter when houses are sealed tight.

We've installed mitigation systems on properties throughout the Dinsmore area, along the Buckland-Dinsmore Road corridor, near State Route 66, and in the surrounding rural acreage common to this part of Auglaize County. The mix of older farmhouses with stone foundations and newer poured-slab builds means we've solved just about every routing puzzle the region throws at us.

For context: Ohio's statewide average indoor radon level is roughly 5.5 pCi/L — already above the EPA's 4.0 pCi/L action level. Auglaize County readings frequently come in higher. If you haven't tested, you're guessing. If you've tested and the result is above 4.0, mitigation isn't optional under any reasonable standard of care — and it's almost always required to close a residential sale.

We also serve nearby communities including Wapakoneta, St. Marys, New Bremen, Cridersville, and the broader Lima metro. Our crews dispatch from our Akron headquarters with full daily coverage of western and central Ohio.

We publish pricing because hiding it is how shady contractors operate. Here's what to expect for affordable Radon Mitigation Dinsmore OH property owners can actually budget against:

• Standard residential ASD system (basement or slab): $1,150 – $1,550
• Crawlspace sub-membrane system: $1,650 – $2,400

• Commercial, multi-family, school systems: custom engineered quote

Financing is available for qualified homeowners — ask about 0% promotional terms when you call. For real-estate transactions, we can invoice the seller's side at closing through the title company so funds release directly from the HUD/CD.
