Radon Mitigation Highland Holiday OH | Licensed RC202 Pros

Ohio has one of the highest indoor radon exposure rates in the United States, and Highland Holiday — tucked into Highland County's limestone and shale geology — falls inside EPA Radon Zone 1, the highest-risk classification. That means homes here are predicted to exceed the EPA action level of 4.0 pCi/L. If your inspection report came back high, you are not an outlier. You are the norm for this part of Ohio.

Radon Eliminator is a licensed Ohio radon mitigation contractor (Ohio License RC202) serving Highland Holiday and the surrounding Highland County communities. We do not sell fans. We sell a code-compliant active sub-slab depressurization system, a clean install behind your siding, a post-mitigation test that proves the number, and paperwork your title company will accept without a second request.

For Radon Mitigation Highland Holiday OH, here is what separates us:

• Ohio License RC202 — stated upfront, on every estimate, on every permit. Most competitors bury or omit their license number.
• Closing-Date Radon Service — we schedule the install around your closing, not our convenience. Mitigation in 1 day, post-test results within 48–96 hours.
• EPA-aligned protocols — testing per ANSI/AARST MAH-2019 and MS-PC 2015 mitigation standards. Defensible in any real-estate negotiation.
• Multi-vertical depth — residential, commercial, schools, and apartment complexes. We are one of the few Ohio shops licensed and equipped for buildings over 2,000 sq ft.
• Guaranteed result — your post-mitigation reading will be below 4.0 pCi/L or we keep working. In writing.

Every property is different. A 1960s ranch on a concrete slab requires a different mitigation design than a new-construction home with a passive stub, a school with multiple HVAC zones, or a 24-unit apartment building. Our scope covers all of it.

The core service: a permanent active sub-slab depressurization (ASD) system, designed specifically for your home's foundation type — full basement, crawlspace, slab-on-grade, or mixed. We core through the slab, seal foundation cracks and sump openings, route 3" or 4" Schedule 40 PVC to the exterior, mount a UL-listed radon fan above the conditioned space, and terminate the discharge above the roofline per Ohio code. Most Highland Holiday homes are completed in 4–6 hours. Typical investment: $1,450–$2,200 depending on foundation complexity and routing.

EPA-aligned short-term (48-hour) and long-term radon testing using continuous radon monitors (CRMs) — not mail-in canisters. CRMs produce hourly data, are tamper-resistant, and meet real-estate disclosure standards in Ohio. Pre-mitigation testing confirms the problem. Post-mitigation testing is required to close out the job and prove your system works.

Schools and licensed daycares in Ohio are increasingly testing for radon, and apartment owners face growing tenant-disclosure expectations. We design and install multi-point mitigation systems for buildings up to 100,000+ sq ft, including manometers at each suction point, fan-failure alarms, and documentation packages built for HUD, the Ohio Department of Health, and insurance carriers.

If your Highland Holiday home already has a radon system but your levels are creeping back above 4.0 pCi/L — failed fan, cracked seal, wrong fan size, or a system installed by someone unlicensed — we diagnose, repair, and re-test. Often a $400–$700 fan replacement or seal repair restores function without a full reinstall.

Our Closing-Date Radon Service is built for the call that starts with "we close in 12 days." Test deployed within 24 hours, results within 96 hours, mitigation installed before your final walkthrough, and a signed post-mitigation test report delivered to your agent and title company. This is the productized service competitors treat as an inconvenience.

A defensible mitigation isn't just a fan on a pipe. Here is exactly how a Highland Holiday job runs from first call to final report.

Tell us your foundation type, square footage, your radon reading, and your timeline. We give you a flat-rate quote on the call — no "we'll have to come out and see" runaround. Most Highland Holiday single-family homes price out in under 10 minutes.

A licensed RC202 technician walks the property, identifies the best suction point (typically the basement slab or sump pit), checks for foundation cracks, evaluates exterior routing options for the discharge stack, and confirms electrical access for the fan circuit. We pull the Highland County mechanical permit when required.

Core the slab, seal the suction point, run sealed Schedule 40 PVC through the conditioned envelope (or exterior, depending on aesthetics), install a UL-listed radon-rated fan, mount the U-tube manometer in a visible location, and terminate the stack above the roofline at least 10 feet from any operable window per AARST standards.

Per EPA protocol, we wait 24 hours for the system to equilibrate, then deploy a CRM for a 48-hour closed-house test. Results are emailed to you, your agent, and your title company. If you're above 4.0 pCi/L, we return at no charge and rework the system.

You receive a digital package: system design diagram, fan model and warranty, manometer instructions, post-mitigation CRM report, Ohio RC202 license copy, and our 5-year system warranty. This is the paperwork that closes deals and satisfies appraisers.

Highland Holiday and the surrounding Highland County area sit on a mix of Ordovician shale, limestone, and glacial till — soils known to release radon as uranium in the bedrock decays. The same geology that gave the region Rocky Fork Lake, the Seven Caves karst features, and the limestone bluffs along Paint Creek also creates the soil-gas pathways that pull radon into basements and slabs.

We have installed systems across Highland County — from Hillsboro and Greenfield to Lynchburg, Leesburg, and the rural roads off US-50 and SR-73. Older farmhouses with stone foundations, mid-century ranches in subdivisions, new builds in the Rocky Fork corridor, and commercial buildings near the downtown Hillsboro corridor each present different mitigation challenges. A stone-foundation home near East Main needs aggressive sealing before the fan can do its job. A walk-out basement off Careytown Road may need dual suction points. A slab-on-grade ranch off SR-124 often runs cleanly on a single 4" suction point with a small fan.

This isn't theoretical. Highland County properties have tested as high as 20+ pCi/L — five times the EPA action level. That's the equivalent radiation exposure of roughly 100 chest X-rays per year, or smoking half a pack of cigarettes a day, according to EPA data. If your kids' bedrooms are in a finished basement, this is the call to make.

We also serve nearby Ohio markets including Columbus, Cleveland, Canton, and surrounding counties.
