If your inspection report just came back at 4.2 pCi/L and your closing is two weeks out, you don't need a sales pitch — you need a licensed contractor who can pull a permit, install a code-compliant system, and hand your title company a post-mitigation test result before the deal collapses. That's what we do. Radon Eliminator is the team Cedarville real-estate agents, home inspectors, and property owners call for Radon Mitigation Cedarville OH work that has to be right the first time.

We operate under Ohio Radon Mitigation License RC202, follow EPA-aligned protocols, and work to the ANSI/AARST consensus standards required by Ohio Department of Health. Most local competitors bury their license number in a footer — or don't list one at all. We lead with ours because in Greene County, an unlicensed mitigation job won't pass a buyer's re-test, won't satisfy a lender, and won't protect your family long-term.

Cedarville sits on the same limestone and glacial-till geology that drives elevated radon across Greene County. Homes near Cedar Lake, properties along US-42, and older basements throughout the village near Cedarville University routinely test above the EPA action level of 4.0 pCi/L. We've seen it. We fix it. And we document it.

Most contractors treat closing-date jobs as an inconvenience. We built our schedule around them. When a Cedarville buyer's inspection flags elevated radon, we can typically test, design, install, and post-test within 7–10 business days — fast enough to keep the deal on the table. Listing agents at brokerages serving Cedarville, Yellow Springs, and Xenia have our number for a reason.

Every mitigation system we install in Cedarville is followed by a post-mitigation radon measurement. If the home isn't under the EPA action level of 4.0 pCi/L, we adjust the system at no additional cost. That guarantee is in writing — not buried in a verbal promise. Lenders, title companies, and home buyers get a clean PDF report they can rely on.

Single-family homes near North Main Street are one job. A 40-unit apartment building, a multi-classroom school wing, or a commercial slab-on-grade off Xenia Avenue is another. We design and install across all four verticals. Apartment owners and school administrators in the Cedarville Local School District have a legal duty of care for indoor air quality — and we're one of the few Ohio teams equipped to deliver multi-point systems at that scale.

Most Cedarville homeowners ask three companies for a price and get three vague answers. We give you an itemized quote: sub-slab depressurization fan, PVC routing, exterior discharge, electrical, sealing, post-mitigation test, and labor. Typical residential Radon Mitigation Cedarville installs range from $1,395 to $2,200 depending on foundation type, basement finish, and discharge routing. Complex or multi-suction-point homes are quoted on-site.

We deliver the full radon lifecycle for Cedarville properties — from initial diagnostic testing to permanent mitigation and long-term monitoring. Every service is performed by Ohio-licensed technicians under RC202.

• EPA-Aligned Radon Testing: 48-hour continuous radon monitor (CRM) tests for real-estate transactions, plus long-term alpha-track testing for owner-occupied diagnostics. Results emailed within 24 hours of pickup.
• Active Sub-Slab Depressurization (ASD): The gold-standard mitigation method for Cedarville basements and slab foundations. We core the slab, route sealed PVC, install a code-rated radon fan, and discharge above the eave line per ANSI/AARST SGM-SF-2017.
• Sub-Membrane Depressurization: For homes with crawlspaces — common in older Cedarville properties off Bridge Street and around the historic district — we install a 6-mil reinforced vapor barrier with negative-pressure extraction.
• Commercial & Multifamily Mitigation: Multi-point ASD systems for apartment complexes, schools, daycare facilities, and commercial buildings. We coordinate with property managers and follow ANSI/AARST CC-1000 for large-building protocols.
• Home Inspector Partner Program: Cedarville-area home inspectors get priority scheduling, co-branded reports, and a published referral structure. If you inspect homes in Greene County and want a radon partner who won't embarrass you, call us.
• System Service & Fan Replacement: Radon fans last 8–12 years. If your existing system was installed by another contractor and the manometer reads flat, we'll diagnose and replace.

Every job follows the same documented sequence. No surprises, no shortcuts.

A licensed technician inspects your Cedarville property — foundation type, sub-slab communication, basement layout, electrical access, and ideal discharge routing. You get a written, itemized quote on the spot or within 24 hours. Real-estate clients get expedited turnaround.

We design the system to ANSI/AARST standards and pull any required permits with the Village of Cedarville or Greene County. Single-suction-point systems are standard; larger or finished basements may need multi-point designs.

Most residential installs are completed in 4–8 hours. We core the slab, seal cracks and sumps, route Schedule 40 PVC, mount the radon fan outside or in an unconditioned attic, wire to dedicated electrical, and install a U-tube manometer so you can verify the system is running at a glance.

24 hours after install, we deploy a continuous radon monitor for a 48-hour post-mitigation test. You receive a signed report showing the new radon level (target: under 4.0 pCi/L, often under 2.0), the system schematic, the warranty, and license documentation. This is the package your title company and lender need.

Cedarville sits in a part of southwest Ohio where the EPA classifies radon potential as Zone 1 — the highest category. The geology beneath Greene County — fractured limestone, dolomite, and glacial deposits — creates ideal pathways for radon gas to migrate from soil into building foundations. The Ohio Department of Health's testing data consistently shows Greene County homes averaging above the 4.0 pCi/L action level.

We've mitigated homes throughout the 45314 ZIP code — from century-old houses near Cedarville University and the Cedarville Opera House, to newer construction in subdivisions north of Massies Creek, to rural properties along Wilberforce-Clifton Road. Each foundation tells a different story: stone basements need different sealing strategies than poured-concrete walk-outs, and crawlspaces under additions require sub-membrane systems most contractors don't install correctly.

We also serve the surrounding communities Cedarville residents share schools, commutes, and real-estate markets with: Yellow Springs, Xenia, Jamestown, Bowersville, Clifton, and the Beavercreek corridor. If your agent is working a deal across Greene County, we can coordinate testing and mitigation on properties in multiple towns under one project.

For schools and apartment owners in the area: Ohio's evolving guidance on radon in occupied buildings means liability is no longer theoretical. We've worked with property managers to bring multifamily portfolios into compliance, with documentation that holds up to insurance and regulatory review.
