If your inspection report came back at 4.2, 7.8, or 12 pCi/L and you have a closing date staring you down, you need a licensed Ohio radon mitigation contractor — not a handyman with a fan. Radon Eliminator holds Ohio Radon Mitigation License RC202, follows EPA-aligned protocols, and installs active sub-slab depressurization systems that reduce radon to below the EPA action level of 4.0 pCi/L. Every job in North Hampton, OH leaves with documentation a buyer's agent, lender, or county health department will accept.

Clark County and the wider Springfield–Dayton corridor sit squarely inside EPA Radon Zone 1 — the highest-risk category, where indoor radon screening averages above 4.0 pCi/L. That isn't marketing language. Ohio has one of the highest radon exposure profiles in the United States, and homes built on the limestone and glacial till under North Hampton frequently test high regardless of age or construction quality. New builds test high. 1920s farmhouses test high. Finished basements with kids' bedrooms test high.

What separates professional Radon Mitigation North Hampton OH service from a generic fan installation is three things: a licensed designer who diagnoses the soil-gas pathway before drilling, a system sized to your specific sub-slab conditions, and a post-mitigation test that proves the number. We do all three on every job.

Most local radon shops only handle single-family homes and treat real-estate-deadline jobs as a scheduling nuisance. We built our business around the opposite: deadline-driven testing, multi-vertical mitigation, and a license number we lead with instead of hide.

• Ohio Mitigation License RC202 — stated upfront, on every quote, every system label, and every closing document.
• Closing-Date Radon Service — testing and mitigation scheduled around your real-estate timeline, not ours. Same-week installs available for North Hampton transactions.
• Guaranteed below 4.0 pCi/L — if the post-mitigation test doesn't drop below the EPA action level, we modify the system at no additional charge.
• Multi-vertical depth — residential, commercial, schools, and apartment complexes. We are one of the few Ohio contractors equipped to mitigate a 40-unit building or a K–8 school under ODH protocols.
• Home-inspector partner program — published pricing and referral terms for the inspectors who refer most of our North Hampton work.
• Clear, written pricing — no "we'll have to come look at it" runaround. Most North Hampton single-family installations fall between $1,250 and $2,200 depending on foundation type and exterior run.

Whether you're a homeowner who just got bad news from a buyer's inspector, a property manager facing a tenant complaint, or a school district responding to mandatory testing, the right system depends on the building. Here's what we install and service across North Hampton and the surrounding Clark County area.

Active sub-slab depressurization (ASD) is the EPA-recommended method for almost every North Hampton home. We core through the slab, seal the foundation penetrations, route Schedule 40 PVC to a quiet exterior or attic-mounted radon fan, and discharge above the roofline per Ohio code. Crawl spaces get sub-membrane depressurization with reinforced 12-mil vapor barrier. Every system includes a U-tube manometer, a system label with our RC202 number, and a written warranty.

Multi-family buildings, daycares, and schools are governed by stricter testing protocols (often AARST-NRPP MAMF and MALB standards) and require engineered designs with multiple suction points, balanced airflow, and continuous monitoring. We handle compliance documentation, work with facilities directors during occupied hours, and stage installations so tenants and students are not displaced.

EPA-aligned short-term testing using continuous radon monitors (CRMs) with hourly readings, tamper logs, and chain-of-custody documentation accepted by lenders, attorneys, and the Ohio Department of Health. Results in 48 hours — fast enough to keep your North Hampton closing on track.

Every system we install is verified with a post-mitigation radon test 24 hours to 30 days after activation. You receive a signed report showing the pre- and post- numbers — the document buyers, sellers, and underwriters actually want to see.

Inherited a 15-year-old system with a dead fan or a manometer reading zero? We diagnose underperforming systems, replace failed Radonaway or Festa fans, reseal slab penetrations, and bring legacy installs up to current Ohio code so they pass re-inspection.

The process below is what we run on a typical North Hampton residential job. Commercial and school work follows the same logic but with engineered drawings and longer commissioning.

A licensed mitigator walks the property, identifies foundation type (slab, crawl, basement, mixed), checks for accessible sub-slab aggregate, locates electrical and discharge routes, and confirms the design. You get a written, fixed-price quote before we leave — not a "ballpark" number.

Most North Hampton single-family installs are completed in 4–8 hours. We core a 4-inch suction point through the slab, vacuum-extract sub-slab debris, seal all visible cracks and penetrations with polyurethane, run sealed PVC to an exterior fan, and discharge 12 inches above the eave per EPA guidance.

Fan is energized, system pressure is measured with a digital micromanometer, and the U-tube is filled and labeled. We walk the homeowner through what a healthy reading looks like and what to call us about.

A continuous radon monitor is deployed for 48 hours under closed-house conditions. The signed report — showing the post-mitigation number under 4.0 pCi/L — is delivered to you, your agent, and (if requested) the buyer's representative.

You receive a closing packet: RC202 license info, system diagram, fan model and warranty, pre- and post- test results, and the transferable system warranty. This is the document that closes the deal.

North Hampton sits at the northern edge of Clark County along SR-41, between Springfield and the Champaign County line. The homes here range from century farmhouses on West Jackson Road to newer construction off North Hampton Road and the neighborhoods south toward Donnelsville and Tremont City. Each foundation type tells us something different about how radon enters — and how to stop it.

Older farmhouses around North Hampton frequently have stone or block foundations with dirt or partial-slab basements; these almost always require a combination of sub-membrane and sub-slab depressurization. Newer subdivisions south toward Springfield and New Carlisle tend to have poured-wall basements with good aggregate underneath — straightforward ASD installs that test well below 2.0 pCi/L post-mitigation. We've worked across Springfield, Enon, New Carlisle, Donnelsville, South Charleston, Urbana, and throughout the I-70/US-40 corridor, so we know the soil and the housing stock.

We also serve commercial and institutional clients across the wider region — apartment owners in Springfield, school districts in Clark and Champaign Counties, and property managers handling multi-building portfolios. The same RC202-licensed crew that installs a single residential system in North Hampton handles the engineered work on larger buildings.
