If a home inspector just handed you a radon result above 4.0 pCi/L, or a buyer's agent is asking for a radon test before closing, you need one thing: a licensed Ohio pro who can fix it permanently and on your timeline. Radon Eliminator provides Radon Mitigation Dennison OH homeowners and real-estate professionals can rely on — installed under Ohio Mitigation License RC202, engineered to EPA standards, and timed to closing windows rather than contractor calendars.

Dennison sits in Tuscarawas County, part of Ohio's elevated-radon belt where the EPA Map of Radon Zones flags much of east-central Ohio as Zone 1 (predicted average indoor radon above 4.0 pCi/L). That's not a scare statistic — it's geology. The shale and limestone bedrock under Dennison, Uhrichsville, and the Tuscarawas River valley naturally produces radon gas that seeps into basements and crawlspaces. The fix is straightforward when it's done right the first time.

We serve homeowners, buyers and sellers, realtors, home inspectors, apartment owners, school districts, and commercial property owners across Dennison and the surrounding Tuscarawas County communities. One phone call, one licensed contractor, one permanent system. Call (330) 871-5734 for a same-day quote.

Most radon contractors won't tell you their Ohio license number on their homepage. We lead with ours: RC202. That license is the difference between a permanent system that passes a post-mitigation re-test and a cheap fan-swap that fails six months later when the buyer's inspector returns.

• Ohio-licensed (RC202) — every install is performed or supervised by a state-licensed mitigation professional, not a general handyman.
• Real-estate deadline guarantee — we schedule testing and mitigation around your closing date. Most Dennison installs are completed within 5–7 business days of contract signing.
• EPA-aligned testing protocols — continuous radon monitors and 48-hour closed-house conditions that hold up to lender and buyer scrutiny.
• Permanent, code-compliant systems — sealed sub-slab depressurization built to ANSI/AARST RMS-SF 2023 standards, not shortcut installs.
• Transparent flat-rate pricing — most Dennison single-family homes fall between $1,295 and $1,795 for a complete system. No surprise add-ons.
• Multi-vertical track record — if Ohio schools, apartment complexes, and commercial buildings trust our systems for regulatory compliance, your Dennison basement is straightforward work.
• Aesthetic-conscious installs — we route exhaust stacks through garages, utility chases, or the rear elevation whenever possible. No ugly white PVC down the front of your house.
• Transferable system warranty — the warranty travels with the home, which is a selling point at your next closing.

The right system depends on your foundation, your radon level, and whether you're racing a purchase agreement. Here's what we install across Dennison properties:

The gold-standard mitigation method for basement and slab-on-grade homes throughout Dennison. We core through the slab, install suction pits, run sealed PVC to a code-rated radon fan, and exhaust above the eave line. This is the system that reliably brings 8–15 pCi/L homes down below 2.0 pCi/L.

Many older homes near downtown Dennison and along Grant Street have dirt or partial crawlspaces. We install a sealed 12-mil vapor barrier, weld seams, and tie the membrane into an active depressurization fan. The crawlspace stops being a radon entry point and becomes a clean, dry buffer.

EPA-protocol 48-hour testing using continuous radon monitors (CRMs) that log hourly data — the kind of test that satisfies a buyer's lender and survives a re-test request. Results in PDF the day the monitor is retrieved. Ideal for sellers who want to disclose proactively and buyers who need certainty before closing.

Apartment owners, daycare operators, and school administrators in the Claymont City School District service area carry legal exposure for radon levels above 4.0 pCi/L. We design multi-point mitigation systems for larger footprints, coordinate testing across multiple units or classrooms, and produce the documentation regulators expect.

Every install is followed by a verification test within 30 days. We document the new pCi/L reading, provide a system labeling package per Ohio code, and hand off paperwork your title company can attach to the closing file.

Whether you're a homeowner with a worrying number or a realtor with a closing in 10 days, the workflow is the same:

1. Phone consultation & quote (same day). Tell us your radon reading, foundation type, and timeline. We quote a flat installed price over the phone for most Dennison homes.
2. On-site assessment. A licensed technician inspects the foundation, identifies the optimal suction point, and confirms exhaust routing that won't damage curb appeal.
3. System installation (one day). Most single-family mitigation systems in Dennison are installed in 4–6 hours. We seal accessible cracks and sumps, install the suction pipe and fan, label the system per Ohio code, and walk you through the manometer.
4. Post-mitigation re-test. A continuous monitor is placed 24 hours after activation. Results are typically below 2.0 pCi/L — well under the EPA action level of 4.0 pCi/L.
5. Closing-ready documentation. You receive the install invoice, system warranty, pre/post test results, and Ohio license disclosure in one PDF packet ready to hand to your title company or buyer.

Dennison's housing stock — from the historic homes near the Dennison Railroad Depot Museum to the newer builds off Sherman Street and the rural properties stretching toward Uhrichsville and Tuscarawas — presents the full range of radon mitigation challenges. Older brick homes near downtown often have stone foundations with significant air gaps. Mid-century ranches along State Route 250 typically have poured concrete basements with cold-joint leakage. Newer slab-on-grade homes have sub-slab gravel beds that respond beautifully to active depressurization.

We've installed mitigation systems across Dennison, Uhrichsville, Tuscarawas, Newcomerstown, Gnadenhutten, Midvale, and throughout the New Philadelphia–Dover corridor. Tuscarawas County readings we've seen in recent years routinely fall in the 5–12 pCi/L range, with some pre-mitigation results topping 20 pCi/L in homes with stone foundations and unconditioned crawlspaces. After mitigation, the same homes consistently test below 2.0 pCi/L.

For Dennison realtors and home inspectors: we operate a dedicated referral lane with priority scheduling, named coordinator contact, and a documented turnaround commitment. Ask about the inspector partner program when you call.
