Ridgeway sits in Hardin County, where Ohio's glacial-till soils and limestone bedrock create some of the highest indoor radon readings in the Midwest. The Ohio Department of Health classifies most of west-central Ohio — including Hardin, Logan, and Union counties — as Zone 1, meaning average indoor radon levels exceed the EPA's 4.0 pCi/L action threshold. That is the reason Radon Mitigation in Ridgeway, OH is not a luxury, and it is the reason we built this company.

Radon Eliminator is a fully licensed Ohio radon mitigation contractor — Ohio License RC202. We list that number on every estimate, every system label, and every post-mitigation report. Most competitors bury or omit their license. We lead with it because the Ohio Department of Health requires it, and because a buyer's attorney will ask for it before closing.

• Licensed Ohio Mitigation Contractor (RC202) — verifiable through the Ohio Department of Health.
• Real-estate deadline specialist — testing and full system installs scheduled around your closing date, not ours. Most jobs in Ridgeway are completed within 3–5 business days of contract signing.
• Guaranteed result under 4.0 pCi/L — every system we install includes a documented post-mitigation test. If the number isn't under the EPA action level, we modify the system at no cost.
• Multi-vertical experience — single-family homes, apartment complexes, schools, and commercial buildings. We're one of the few Ohio firms equipped for large-building diagnostics and sub-slab depressurization at scale.
• Clear, flat-rate pricing — no vague "starting at" language. You get a written quote with the system specs, fan model, warranty, and timeline before we begin.

When Ridgeway homeowners search for the best Radon Mitigation Radon Mitigation In Ridgeway option, they're really asking three questions: Is this contractor actually licensed in Ohio? Will the system actually drop my number below 4.0? And will it be done before my closing date? Our answer to all three is yes, in writing.

Hardin County properties present a specific mix of construction styles — older farmhouses with rubble-stone foundations, mid-century ranches with poured-slab basements, and newer builds along US-33 with poly-sealed crawlspaces. Each requires a different mitigation approach. Below are the core Radon Mitigation services Radon Mitigation In Ridgeway OH property owners call us for.

The gold-standard mitigation method for basements and slab-on-grade homes. We core a suction point through the slab, run sealed 3- or 4-inch PVC to an exterior or attic-mounted radon fan, and exhaust above the eave line per EPA Protocol 2017. Typical Ridgeway installation: one suction point, one RadonAway RP145 or GP501 fan, manometer, and labeled service disconnect. Most single-family installs complete in 4–6 hours.

Many older homes north of SR-31 have dirt or partial crawlspaces. We install a 12-mil reinforced vapor barrier, seal seams and piers, and tie the membrane into a depressurization fan. This addresses both radon and the moisture issues that cause Hardin County's common mold complaints.

This is our productized Closing-Date Radon Service. We deploy a continuous radon monitor (CRM) for a 48-hour EPA-protocol test, deliver a signed report your buyer's agent and lender will accept, and — if elevated — install the mitigation system before your closing date. We coordinate directly with your title company and inspector. No back-and-forth.

Ohio Revised Code requires public schools and licensed childcare facilities to test for radon, and most commercial lenders now require it on multi-family acquisitions. We design and install large-building mitigation systems with multiple suction points, variable-speed fans, and U-tube manometers at each riser. We've worked on apartment complexes, K-12 buildings, and assisted-living facilities across central Ohio.

Every install includes a post-mitigation radon test 24 hours to 30 days after activation. We also service systems installed by other contractors — fan replacements, suction-point diagnostics, manometer issues, and re-testing for resale.

Our process is built around one number: getting your home below 4.0 pCi/L and documenting it. Here is exactly what happens when you hire the top Radon Mitigation Radon Mitigation In Ridgeway OH team.

Call us with your address, foundation type, and (if you have one) your inspection report's radon reading. Most Ridgeway homes get a firm written quote within the same business day. We don't do bait-and-switch "starting at" pricing.

Our licensed technician walks the basement or crawlspace, identifies the optimal suction point using a smoke-pen communication test, checks for sealed sumps and crawlspace access, and confirms the exterior fan-routing path. This takes 30–45 minutes.

Installation takes one day for typical single-family Ridgeway homes. We core the slab, run schedule-40 PVC, install the radon fan with a service disconnect, mount a U-tube manometer, seal all visible foundation cracks and the sump cover, and label the system per ANSI/AARST standards.

We place a continuous radon monitor for at least 48 hours after the system has been running for 24 hours. You receive a signed, EPA-protocol report showing your new pCi/L reading. If you're closing, this report goes directly to your agent and title company.

Every Radon Eliminator system carries a 5-year workmanship warranty and the manufacturer's fan warranty (typically 5 years on RadonAway units). If your reading creeps back above 4.0 pCi/L within the warranty period, we return and adjust at no cost.

Ridgeway is a village split between Hardin and Logan counties along US-33, with most of its housing stock built between 1900 and 1985. That matters because radon enters homes through cracks in older foundations, unsealed sumps, and dirt crawlspaces — all common features in this area.

The Ohio Department of Health's radon-zone map places Hardin County in Zone 1 (highest risk), with an average indoor screening level above 4.0 pCi/L. Neighboring Logan, Union, and Champaign counties are also Zone 1. Homes near the Scioto Marsh, along CR-130, and the older residential blocks off Main Street tend to test highest because of the underlying limestone and shale formations that release radon as uranium decays.

We regularly install systems for clients in Ridgeway, Kenton, Bellefontaine, West Liberty, Marysville, and the Indian Lake area. Many of our Ridgeway referrals come through home inspectors working US-33 corridor real-estate deals, where a high radon number can stall a contract for weeks if you don't have a licensed mitigator ready to move.
