Ohio has one of the highest indoor radon exposure levels in the United States, and Addison sits squarely inside that geology. When a home inspector hands you a report showing 4.2, 7.8, or 14 pCi/L, you don't need marketing — you need a licensed Ohio radon mitigation contractor who can install a permanent system, retest, and hand you documentation a buyer's agent will accept.

That's what Radon Eliminator does. We hold Ohio Radon Mitigation License RC202, we follow EPA-aligned protocols on every job, and we guarantee your post-mitigation reading drops below the EPA action level of 4.0 pCi/L. For Radon Mitigation Addison OH homeowners, that means one call, one licensed crew, and one number you can defend at the closing table.

We don't sell radon fans. We sell engineered sub-slab depressurization systems, sealed sumps, properly routed PVC, exterior discharge above the eave line, a manometer you can read from across the room, and a written post-install radon test. That's the deliverable.

• License: Ohio RC202 — stated upfront on every quote
• Standard: EPA-aligned testing and ANSI/AARST mitigation protocols
• Guarantee: Post-mitigation radon level below 4.0 pCi/L or we adjust the system at no cost
• Timeline: Most Addison installs completed in 4–6 hours, same-week scheduling available
• Documentation: Written test results and system specs suitable for real-estate transactions

Most Addison homeowners calling about radon are in one of three situations: a real-estate deal with a closing date breathing down their neck, a long-term resident who just learned the basement bedrooms have been logging unsafe pCi/L numbers, or a property manager with state-mandated testing on a multi-unit building. Each one needs a different response, and a generic handyman-grade radon installer isn't equipped for any of them.

Real-Estate Deadline Specialists

If your purchase agreement says the seller will mitigate before closing, the clock is the project. We productize this as our Closing-Date Radon Service: test, install, retest, and deliver the paperwork — coordinated with your agent, title company, and inspector. We've completed mitigations in Addison and surrounding Wayne and Stark County communities in under 7 business days when the contract demanded it.

Ohio License RC202 — On Every Quote

Ohio law requires anyone installing a radon mitigation system to hold a state mitigation license. Many competitors omit their license number from their website and their estimates. We lead with ours: RC202. If a contractor can't or won't show you their Ohio radon license, they cannot legally install your system, and any post-mitigation test they provide is not defensible in a real-estate transaction.

Residential, Commercial, Schools, and Apartments

Most local radon shops only handle single-family homes. We mitigate apartment complexes, condominium buildings, commercial properties, and Ohio K–12 schools — all of which have separate legal exposure standards and require multi-point testing, larger fan curves, and engineered routing. If you manage a building in Addison, we are likely the only Ohio-licensed call on your list with that vertical experience.

Home Inspector Partner Program

Addison-area home inspectors who refer radon work to us get priority scheduling, transparent referral terms, and a published partner offer for their clients. Inspectors don't have to apologize for the wait time or guess at pricing — they hand off a known quantity.

Clear, Written Pricing

One of the most common complaints we hear is, "I called three companies and none of them would give me a straight price." We quote in writing, itemized, with the system type, fan model, routing, sealing scope, and post-mitigation test included. No day-of upsells.

Radon Eliminator provides the full radon lifecycle for Addison properties. Whether you need a one-time short-term test before a closing or a complete commercial mitigation buildout, the same licensed RC202 team handles it.

Residential Radon Testing

EPA-aligned short-term (48–96 hour) and long-term radon tests using continuous radon monitors (CRMs), not mail-in charcoal kits. Results are delivered with a chain-of-custody report acceptable to lenders, agents, and Ohio Department of Health protocols.

Residential Radon Mitigation System Installation

Active sub-slab depressurization is our standard residential design — the only mitigation method the EPA recognizes as consistently reducing radon to below 4.0 pCi/L in Ohio's clay-and-shale soil profile. We also install sub-membrane systems for crawlspaces, drain-tile depressurization, and block-wall systems where warranted.

Commercial & Apartment Radon Mitigation

Multi-unit and commercial properties in Addison require engineered designs: zone testing, multiple suction points, manometers per zone, and fans sized to the slab area. We handle permitting, tenant notification timing, and post-install verification testing for every affected unit.

School Radon Testing and Mitigation

Ohio schools have specific radon testing obligations. We provide multi-classroom testing campaigns, occupied-hours protocols, and mitigation designs that meet ANSI/AARST-RMS-LB standards for large buildings.

Post-Mitigation Verification Testing

Every install includes a post-mitigation radon test. If the reading is not below 4.0 pCi/L, we return and adjust the system — fan upgrade, additional suction point, or sealing — at no additional cost.

Existing System Inspection and Upgrades

If you bought a home with an older radon system and the manometer reads zero (or the fan is silent), call us. We diagnose, repair, and upgrade legacy systems — often a failed fan or a routing problem from a non-licensed installer.

24/7 On-Site Radon Assessment

For urgent real-estate, commercial, or post-flooding situations in Addison, we offer same-day or next-day on-site assessment across Ohio.

Every Radon Mitigation Addison OH project follows the same defensible, EPA-aligned sequence. No shortcuts, no day-of guesswork.

1. Diagnostic Testing

We deploy a continuous radon monitor in the lowest livable level for a minimum 48-hour closed-house test. You receive a time-stamped graph, an average pCi/L, and our recommendation in writing.

2. System Design and Written Quote

Our licensed designer evaluates your foundation type (slab, crawlspace, basement, mixed), sub-slab communication, sump configuration, electrical access, and aesthetic routing options. You get an itemized quote with fan model, pipe routing, suction points, and the guaranteed post-mitigation target.

3. Installation by Licensed RC202 Technicians

Most Addison residential installs are completed in a single day, 4–6 hours typical. We core the slab, install Schedule 40 PVC, seal all penetrations and sump lids, route exterior discharge above the eave per code, mount the radon fan outside the conditioned envelope, and install a U-tube manometer.

4. Post-Mitigation Verification Test

A second 48-hour CRM test confirms your radon level is below 4.0 pCi/L. We provide the written report — the document your real-estate agent, buyer, or lender actually wants.

5. Documentation, Warranty, and Handoff

You receive system specs, the warranty, the post-mitigation test, and instructions for reading the manometer. For real-estate jobs, we deliver directly to your title company on request.

Addison and the surrounding Wayne County corridor sit on the glaciated Allegheny Plateau — a geology defined by fractured shale, limestone deposits, and uranium-bearing soils that produce radon gas as they decay. The Ohio Department of Health classifies most of this region as Zone 1, the highest radon potential category, with predicted average indoor radon levels above 4.0 pCi/L.

In practical terms, that means a home in Addison is statistically more likely to test high than a home in a coastal city. Older homes with block foundations, homes with basement bedrooms or finished lower levels, and homes with sump pits are at elevated risk regardless of age. Newer builds aren't immune either — tighter construction actually traps radon more efficiently once it enters.

We service Addison and the broader region including Wooster, Orrville, Doylestown, Rittman, Smithville, Apple Creek, Mount Eaton, and the rural townships in between. Our crews know the local soil behavior, the typical foundation styles, and which neighborhoods historically test higher. That regional fluency is the difference between a system that's designed for your slab and a system that's copy-pasted from a national playbook.

For families with kids sleeping in basement bedrooms — common in Addison's split-level and ranch housing stock — the exposure math is not theoretical. Radon is the second-leading cause of lung cancer in the U.S. according to the EPA, and the only cause among non-smokers. A properly designed mitigation system removes that variable from your home, permanently.

Most single-family Radon Mitigation Addison projects fall between $1,200 and $2,200 installed, including the post-mitigation verification test. The variables that move the price:

• Foundation type: Slab-on-grade with an accessible sump is the lowest cost; mixed foundations with crawlspaces cost more
• Routing complexity: Interior routing through a closet to the roof costs more than exterior routing up a side wall
• Suction points: Larger or poorly communicating slabs may require 2+ suction points
• Sealing scope: Open sumps, large slab cracks, and unsealed crawlspaces add labor

Commercial, school, and multi-unit pricing is quoted per building after a site walk. We do not quote those sight-unseen, and we don't trust competitors who do.
