Sardinia sits in Brown County, which the Ohio Department of Health places in EPA Radon Zone 1 — the highest-risk category, where the predicted average indoor radon screening level exceeds 4.0 pCi/L. The shale and limestone bedrock under Highway 32 and the older farmhouses scattered along Tri-County Highway and Bachman Road releases radon gas as it decays. That gas finds its way through basement floor cracks, sump pits, and crawlspace dirt floors. It's not a defect. It's geology.

Radon Eliminator handles Radon Mitigation Sardinia OH homeowners need when a test comes back high — usually during a real-estate transaction, sometimes after a DIY kit confirms a number the family can't ignore. We're Ohio licensed under RC202, EPA-aligned in every test we run, and built around one promise: a permanent fix, installed fast enough to close on time.

Call (xxx) xxx-xxxx for same-day scheduling, or request a written estimate online. No mystery pricing. No re-test surprises.

Most radon contractors in southern Ohio bury their license number, give a verbal price over the phone, and book you out three weeks. That timeline kills real-estate deals. Here's what separates us:

• Ohio Mitigation License RC202 — printed on every quote, every permit, every system label. Verify it with the Ohio Department of Health before we show up.
• Closing-deadline turnaround — when a Sardinia buyer's agent gives us a date, we hit it. Most residential systems are installed in a single day, and post-mitigation testing starts within 24 hours.
• Transparent, written pricing — typical single-family radon mitigation in Sardinia runs $1,400–$2,200 for a standard sub-slab depressurization system. Crawlspaces, multi-zone basements, and commercial buildings are quoted line by line, never lumped.
• Permanent, code-compliant systems — not a fan-swap on someone else's failing pipe. Every install meets ANSI/AARST standards, with a sealed suction point, manometer, exterior discharge above the eave, and a labeled electrical disconnect.
• Multi-vertical credibility — we mitigate Ohio schools, apartment complexes, and commercial properties under the same RC202 license. If a district trusts us with a building full of kids, your basement is a straightforward job.
• Realtor and home-inspector referral lane — we publish a named Special Offer for Sardinia-area inspectors and agents who refer clients, because we know the deal clock is the real clock.

We handle the full radon workflow — testing, mitigation, post-mitigation verification, and re-testing for properties with failed prior systems. Every service is delivered by RC202-licensed technicians, never subcontracted.

Short-term continuous radon monitor (CRM) tests for real-estate transactions return results in 48 hours with a printed, signed report acceptable to lenders, title companies, and Ohio disclosure requirements. Long-term alpha-track testing is available for owner-occupied homes where you want a 90-day average rather than a closing-window snapshot.

For the typical Sardinia ranch or two-story with a poured basement, sub-slab depressurization is the proven fix. We core a suction point through the slab, seal it, run rigid PVC to a roof-line exhaust, and install an inline fan rated for your home's footprint. A wall-mounted manometer gives you a permanent visual check that the system is pulling. Most installs finish in 4–6 hours.

Many of the older homes around Sardinia and out toward Mowrystown have partial crawlspaces or dirt floors. We seal the crawlspace with a reinforced vapor barrier, tape the seams, and depressurize beneath the membrane. This stops radon at the source and dries the crawl out as a bonus — useful for any buyer's inspector who flagged moisture too.

Commercial property owners, multi-family landlords, and school administrators have legal exposure if radon levels go ignored. We design multi-suction-point systems, zone the building correctly, document everything for your insurer or board, and schedule installs around occupancy. Sardinia-area apartment owners along Main Street and small commercial buildings near the SR-32 corridor have used us for this exact work.

Inherited a cheap fan-swap job from a previous owner that's reading 6.8 pCi/L on re-test? We diagnose, repair, or replace failing systems and re-route ugly exterior pipe runs to the back or side of the house where curb appeal isn't destroyed. This is one of the most common pain points we hear: 'I don't want a white pipe on the front of my house.' We agree.

Built for real-estate timelines, not contractor calendars.

1. Phone or online intake (Day 1). You give us the pCi/L number, the property address, and the closing date if there is one. We confirm whether you need a re-test, a fresh test, or straight to mitigation. Written estimate emailed the same day.
2. On-site assessment (Day 2–3). An RC202 technician walks the basement, crawlspace, slab, and exterior. We identify suction points, fan sizing, electrical access, and the cleanest exterior pipe route. You approve the plan in writing.
3. Installation (typically one day). Sub-slab coring, sealing, PVC routing, fan mount, manometer, electrical, and labeling. The crew cleans up. The system is running before we leave.
4. Post-mitigation testing (Days 4–6). We deploy a continuous radon monitor for 48 hours. You get a signed report showing the new level — almost always under 2.0 pCi/L — that satisfies buyers, lenders, and Ohio disclosure paperwork.

Sardinia is a small village, but the radon picture here is shaped by the broader Brown and Highland County geology. We've installed systems on homes off Tri-County Highway, in the neighborhoods around Eastern High School, and out toward Russellville and Mowrystown. We know which subdivisions have block foundations versus poured walls, which 1970s ranches have the buried sump pits that complicate suction-point design, and which septic and well configurations affect where we can safely vent.

We also work the entire SR-32 corridor — Mt. Orab, Hamersville, Williamsburg — and tie back into our Cincinnati and Columbus operations when a real-estate client owns property in multiple markets. Sardinia homeowners benefit from a metro-grade radon team that actually shows up in Brown County, not a one-truck operation that disappears after the install.
