If you just got a real-estate inspection report flagging elevated radon, or your test strip came back at 4.2 pCi/L, 6.8 pCi/L, or higher — you're not overreacting. Licking County sits in EPA Radon Zone 1, the highest risk category in the country. Granville South homes, particularly those built on the limestone and shale formations underlying the Raccoon Creek valley, frequently test well above the EPA action level of 4.0 pCi/L.

Radon Eliminator is the licensed Ohio radon mitigation contractor (Ohio Mitigation License RC202) that real-estate agents, home inspectors, and property owners call when the timeline is tight and the number has to come down — permanently and on paper. We don't sell fans. We sell a complete, code-compliant Radon Mitigation Granville South OH system, a clean install, and post-mitigation verification that documents your home is under 4.0 pCi/L.

Every property is different. A 1970s ranch off Newark-Granville Road has a different sub-slab profile than a new build in the Erinwood subdivision or a brick walk-out near Raccoon Valley Park. Our certified mitigators design each system around the actual building — foundation type, soil permeability, HVAC layout, and the post-mitigation target you need on paper.

Active soil depressurization (ASD) is the EPA-recommended gold standard, and it's what we install in 95% of Granville South homes. We core through the slab, seal sump pits and floor cracks, route schedule-40 PVC through a concealed chase or the garage, and finish with a quiet, ECM-equipped radon fan rated for Ohio winters. A wall-mounted U-tube manometer gives you a visible system-active indicator. Standard install: one day, typically $1,150–$1,950, depending on foundation complexity.

Buyers, sellers, and listing agents in Granville South use our Closing-Date Radon Service when the deal is on the line. We deliver continuous-monitor testing with 48-hour results, written mitigation quotes within 24 hours of an elevated reading, install within 5–7 business days, and post-mitigation verification documentation that satisfies lender and buyer requirements. If your closing is in two weeks, that's our problem, not yours.

Most local radon shops only work on single-family homes. We don't. Multifamily buildings off Cherry Valley Road, Granville-area school facilities, and commercial properties in the Route 16 corridor have legal exposure obligations under Ohio Administrative Code 3701-69. We design multi-point ASD systems, sub-membrane systems for crawl spaces, and HVAC-integrated solutions for larger buildings — with the documentation property owners and risk managers actually need.

Installing a fan isn't mitigation. Mitigation is a documented, sub-4.0 pCi/L result. After every install, we run an EPA-protocol post-mitigation test and provide written verification. If your home doesn't come down below 4.0 pCi/L, we modify the system at no additional cost.

Bought a Granville South home with an older mitigation system? Fans wear out (typical lifespan 8–12 years), seals fail, and pre-2010 systems often don't meet current ANSI/AARST standards. We inspect, diagnose, retest, and bring legacy systems up to current code — usually for less than half the cost of a new install.

Our process is standardized so the result is predictable. Here's exactly what happens when you hire the top Radon Mitigation Granville South team.

Call (614) 333-1535. We ask about your foundation type, basement layout, test results, and timeline. You receive a written estimate the same day — itemized, with the system design and pricing locked in. No 'we'll get back to you next week.'

A licensed RC202 mitigator performs a sub-slab communication test, inspects sump pits, floor cracks, and crawl space membranes, and locates the optimal suction point and exterior fan location. The goal is a quiet, hidden, effective system — not a pipe bolted to your front-facing exterior wall.

Core drilling, sealing, PVC routing, fan mounting, electrical connection (when permitted, we use a licensed electrician on a dedicated circuit), and manometer installation. We protect floors, vacuum concrete dust, and haul away all debris. Your home is clean when we leave.

After a minimum 24-hour closed-house period, we deploy an EPA-protocol post-mitigation test. You receive a signed report showing the final pCi/L reading, system specifications, fan model and serial number, and warranty information — the documentation lenders, buyers, and insurance carriers require.

Every system carries a 5-year workmanship warranty and a fan manufacturer warranty. We guarantee post-mitigation results below 4.0 pCi/L. If the number isn't there, we come back and modify the system — no charge, no argument.

Granville South sits on the western edge of the Allegheny Plateau, where uranium-bearing Ohio Shale and Bedford Shale formations release radon gas as they decay. The Ohio Department of Health's county-level data shows Licking County averages well above the national mean, with a substantial percentage of tested homes exceeding 4.0 pCi/L.

Geography compounds the issue. Granville South homes with finished basements — common in the neighborhoods south of State Route 16 and along Columbus Road — concentrate radon in exactly the living spaces families spend the most time in. Children's bedrooms, home offices, and family rooms in walk-out basements near Raccoon Creek frequently test highest.

We've installed mitigation systems throughout the greater Granville area, including homes near Denison University, properties along Newark-Granville Road, the Bryn Du area, and rural parcels off Burg Street. We also serve the broader region — Newark, Heath, Pataskala, Johnstown, Alexandria, and into Columbus and the eastern Franklin County suburbs. Our crews know the soil, the foundation styles common to mid-century Granville ranches, and the newer construction patterns in subdivisions built since 2000.

That local knowledge matters. A generic Radon Mitigation services Granville South OH contractor from out of state quotes one design for every home. We design for the specific geology under your slab.

One of the most common complaints we hear: 'I called three companies and none of them would give me a straight price.' Here's ours.

• Complex residential system: $1,650–$1,950 (multiple suction points, crawl space membrane, or finished-basement routing)
• Short-term radon test (charcoal canister): $145
• Real-estate continuous monitor test (48 hours, results next day): $195
