If your inspection report came back high and your closing date is two weeks away, you do not have time for a contractor who books three weeks out and won't quote a price. Radon Eliminator is Ohio's licensed radon mitigation contractor (Ohio Mitigation License RC202), and we built our entire Radon Mitigation Norwich OH operation around the one thing most competitors treat as an afterthought: the deadline.

Muskingum County sits in an EPA Radon Zone with elevated soil-gas potential, and Norwich homes — many of them older farmhouses, ranches with block foundations, and newer builds along the I-70 corridor — routinely test above the EPA action level of 4.0 pCi/L. We install active soil depressurization (ASD) systems engineered to ANSI/AARST standards, then verify the result with a post-mitigation test. You get a number, in writing, that closes the deal and protects your family.

We are not a general contractor who happens to install fans. Radon is the only thing we do. That focus is why agents, inspectors, and property managers across Norwich, Zanesville, New Concord, and the broader Muskingum Valley keep our number saved.

• Ohio License RC202 — stated upfront on every quote, contract, and invoice
• EPA-aligned testing protocols — closed-house conditions, 48-hour minimum, certified devices
• Closing-Date Radon Service — testing and mitigation scheduled around your settlement, not ours
• Residential, commercial, school, and apartment mitigation — one Ohio call for every property type
• Post-mitigation verification documented below 4.0 pCi/L — guaranteed in writing

There are radon contractors who will sell you a fan. We sell a code-compliant system, a clean install, and a documented number. That difference shows up in three places: the license, the timeline, and the paperwork.

Ohio License RC202 — Led, Not Buried

Ohio requires every radon mitigation contractor to hold a state-issued license. Most local shops bury the number in a website footer or skip it entirely. Ours is on the truck, the contract, and the permit. If a contractor cannot give you their RC202 number before they walk your basement, do not let them install a system in your home.

Built for Real-Estate Transactions

We productized the closing-date job. When you call about a Norwich property under contract, we ask three questions: settlement date, current radon level, and access. Then we tell you — on that call — whether we can hit your deadline and what it will cost. Buyers, sellers, and listing agents from RE/MAX, Coldwell Banker, and Howard Hanna offices across Muskingum County route radon work to us because the answer is never "we'll get back to you."

Multi-Vertical Depth Most Norwich Shops Don't Have

Single-family homes are the bulk of our work, but we also mitigate apartment complexes, commercial buildings, daycares, and K–12 schools across Ohio. That matters in Norwich because property managers and school facility directors who are legally responsible for occupant safety need a contractor who has actually engineered multi-unit and large-slab systems — not a residential installer guessing at scale.

Home-Inspector Partner Program

If you're a Norwich-area home inspector, we have a published referral program with a standing offer for your clients. Your buyers get priority scheduling and transparent pricing; you get a radon partner who won't blow a deadline and embarrass your referral. Ask about the inspector program when you call.

Every Norwich home and building is different — slab-on-grade, full basement, crawlspace, block foundation, sump pit, drain tile. Our system design is tailored to the structure, not pulled from a catalog. Here is what we install and verify.

Residential Radon Mitigation System Installation

Active soil depressurization is the gold standard for Ohio homes. We core through the slab, seal the suction point, route schedule-40 PVC through an unobtrusive path (interior chase, garage, or exterior wall), and install an inline radon fan sized to your soil permeability. Every system includes a manometer, electrical disconnect, exterior discharge above the eave line per EPA guidance, and full sealing of foundation penetrations. Most Norwich residential installs are completed in 4 to 8 hours.

Commercial, Apartment, and School Mitigation

Large-footprint buildings require multi-point suction, engineered fan staging, and often building-pressure balancing. We have installed systems in Ohio schools, multi-family complexes, medical offices, and warehouses. Every commercial job includes engineered drawings, post-mitigation diagnostic testing at multiple locations, and documentation suitable for your insurance carrier, lender, or state licensing inspector.

EPA-Aligned Radon Testing — Residential and Commercial

Pre-mitigation testing uses continuous radon monitors (CRMs) under closed-house protocol for a minimum of 48 hours. For real-estate transactions we deliver results within hours of pickup. For schools and large commercial buildings we follow ANSI/AARST MAMF and MALB protocols with multi-room sampling.

Post-Mitigation Verification Testing

Installing a system isn't the job — getting the number under 4.0 pCi/L is the job. Every install includes a post-mitigation test, and we don't close the file until your home is documented below the EPA action level. If a system underperforms, we return and rework it at our cost.

Inspection and Upgrade of Existing Systems

Bought a Norwich home with a mitigation system already installed? We inspect existing systems, test current performance, and upgrade undersized fans, leaking suction points, or non-compliant discharge routes. Many systems installed in the 2000s used fans that have since failed silently — your manometer might read zero and you'd never know without a test.

24/7 On-Site Radon Assessment and Consultation

For commercial clients and time-sensitive transactions, we offer same-day site visits across Norwich and the surrounding Muskingum County area.

You should know exactly what happens and when. Here is the process for a typical Norwich radon mitigation job.

Step 1: Phone Consultation and Transparent Quote

Call us with your address, current radon level (if tested), and timeline. We ask about foundation type, basement layout, sump pit, and finished spaces. Most residential quotes are issued on the same call. No "we'll send someone out for an estimate" runaround.

Step 2: Site Diagnostic and System Design

We walk the property, identify the optimal suction point, plan the pipe route to minimize visual impact, and confirm electrical access. For homes with sub-slab drain tile or interior perimeter footings, we adjust the design to take advantage of existing pathways.

Step 3: Code-Compliant Installation

Installation is typically completed in a single visit. We protect floors and finished surfaces, contain dust during slab coring, and clean the site before we leave. All work meets ANSI/AARST CC-1000 mitigation standards and Ohio Department of Health requirements.

Step 4: Post-Mitigation Test and Documentation

A continuous radon monitor is deployed for 48 hours after installation. You receive a written report showing pre- and post-mitigation levels, the system specifications, the warranty, and the RC202 license number — everything a buyer's agent, lender, or county records search will ever ask for.

Step 5: Long-Term System Warranty

Our installations carry a workmanship warranty and the fan manufacturer's warranty (typically five years). We recommend retesting every two years per EPA guidance, and we'll send the reminder.

Ohio has one of the highest radon exposure levels in the United States. The EPA classifies most of Ohio — including Muskingum County and Norwich — as Zone 1, the highest-risk designation, with predicted average indoor radon levels above 4.0 pCi/L. That isn't marketing language; it's the federal map.

Norwich sits on a geology of glacial till, sandstone, and shale — soils that allow radon gas to migrate readily into basements and crawlspaces. We've mitigated homes along Old National Road (US-40), properties near the National Road / Zane Grey Museum corridor, and farmhouses on the rural routes between Norwich and New Concord. We also serve nearby communities including Zanesville, Cambridge, New Concord, Adamsville, and properties throughout the I-70 corridor between Columbus and Wheeling.

Older Norwich homes with block-wall basements are particularly susceptible because porous block walls and unsealed cove joints create direct radon pathways. Newer construction with poured concrete slabs is not immune — tight, energy-efficient homes can actually concentrate radon faster because of reduced air exchange.

For Norwich school districts, apartment owners around the East Muskingum area, and commercial property owners along the SR-40 and SR-83 corridors: Ohio law and HUD guidance increasingly require radon testing for multi-family and public buildings. We handle the testing, the mitigation design, and the documentation in one engagement.

You called three companies and none would give you a straight price. Here's ours.

Most residential Radon Mitigation Norwich OH systems fall between $1,200 and $2,200, depending on foundation type, suction-point count, and pipe routing complexity. Standard basement homes with a single interior suction point typically come in at the lower end. Multi-level homes, crawlspace encapsulation work, or exterior routing with custom finishing trend higher.

• Standard basement mitigation: $1,200 – $1,600
• Crawlspace mitigation with vapor barrier: $1,800 – $2,800
• Multi-suction-point or large home: $2,200 – $3,500
• Pre-mitigation radon test: $145 – $195 (often credited toward installation)
• Post-mitigation verification test: included with every install
• Commercial, school, apartment systems: engineered quote — call for site visit

We offer financing for qualified homeowners and accept all major payment methods. Real-estate escrow payment is also accepted for closing-day installations.
