If you're searching for Radon Mitigation Cambridge OH, odds are you're already under pressure. Maybe your home inspector's report just came back at 6.8 pCi/L and your closing is fourteen days out. Maybe you're a Guernsey County landlord who just learned Ohio has one of the highest average radon levels in the country. Maybe your kids' bedrooms are in the basement of a ranch off Southgate Parkway and you've been losing sleep since you read the EPA's action-level guidance.

Radon Eliminator is Ohio's licensed radon mitigation company — Ohio Mitigation License RC202 — serving Cambridge, Byesville, Old Washington, Lore City, and the rest of Guernsey County with EPA-aligned testing and permanent, code-compliant systems. We don't sell fans. We sell a documented number below 4.0 pCi/L and a clean install your real-estate agent, inspector, and buyer will all sign off on.

That distinction matters in Cambridge. Southeastern Ohio sits on glacially deposited soils and shale-rich bedrock that consistently produce elevated radon readings. Guernsey County is classified by the EPA as Zone 1 — the highest-risk designation, meaning predicted indoor radon screening levels average above 4.0 pCi/L. That isn't a marketing line. It's geology.

What sets our Cambridge service apart

• Licensed Ohio professionals (RC202) — we lead with our license number because most competitors hide theirs.
• Closing-Date Radon Service — productized for real-estate transactions. We work to your settlement date, not our scheduling convenience.
• Multi-vertical capability — single-family homes, apartment complexes, commercial buildings, and schools. Most local shops only do houses.
• Transparent pricing — flat-rate quotes after a site walk, not vague "it depends" estimates.
• Post-mitigation testing included — every job ends with a documented reading you can hand to the buyer, lender, or board of health.

Whether you're a homeowner in the Wills Creek area, an investor with a fourplex near Cambridge City Park, or a facilities director at a school in the Rolling Hills district, our scope is built around the realities of southeastern Ohio housing stock — basements over crawlspaces, slab additions, fieldstone foundations, and older block walls that leak soil gas.

Residential Radon Mitigation

Active soil depressurization (ASD) is the EPA-recognized gold standard, and it's what we install on the vast majority of Cambridge homes. We core through the slab, seal the suction point, route 3- or 4-inch Schedule 40 PVC to the exterior or through the garage, and install a properly sized radon fan (typically a Radonaway RP145, RP265, or HP2000 depending on subslab permeability). Every system includes a U-tube manometer, exterior discharge above the eave per ASTM E2121, and labeled service points.

Real-Estate Closing-Date Service

This is the service buyers, sellers, and Cambridge-area agents call us for most. We turn around an EPA-aligned 48-hour test, install a mitigation system within days of contract acceptance, retest, and deliver a signed report — all before settlement. We've structured this around real timelines, not contractor calendars.

Commercial & Apartment Building Mitigation

Multifamily and commercial buildings require a different engineering approach: multiple suction points, balanced fan staging, and sometimes sub-membrane depressurization for crawlspace zones. We handle Cambridge apartment complexes, assisted-living facilities, and office buildings under the same RC202 license and ANSI/AARST CC-1000 commercial standards.

School Mitigation

Ohio school boards have a legal duty of care around indoor air quality. We mitigate under ANSI/AARST RMS-LB protocols, coordinate around the academic calendar, and provide the documentation administrators need for board meetings and parent communications.

Radon Testing & Post-Mitigation Verification

Short-term continuous radon monitor (CRM) tests, long-term alpha-track tests, and post-mitigation clearance testing — all EPA-aligned, all defensible in a real-estate transaction.

Every Cambridge project follows the same disciplined five-step sequence. No improvisation, no surprises on invoice day.

Step 1 — Diagnostic Site Visit

A licensed mitigator inspects your foundation type, slab condition, sump configuration, HVAC layout, and existing test data. For Cambridge homes with older block foundations — common throughout the Wheeling Avenue historic district and surrounding neighborhoods — we evaluate wall cavity contribution before recommending a suction strategy.

Step 2 — Flat-Rate Quote

You get a written quote with a fixed price, the fan model we'll install, the routing path, the warranty terms, and the expected post-mitigation pCi/L range. We don't quote ranges or upcharge mid-job.

Step 3 — Installation

Most single-family Cambridge installations take 4 to 8 hours. We protect floors, contain dust, and route piping to be as visually unobtrusive as possible. Exterior discharge meets the 10-foot horizontal/2-foot vertical clearance from windows per ASTM E2121.

Step 4 — Post-Mitigation Test

We deploy a continuous radon monitor for a minimum 48-hour closed-house test after the system has run for at least 24 hours. The target is below 4.0 pCi/L; our average post-mitigation result statewide is below 1.5 pCi/L.

Step 5 — Documentation Package

You receive a signed report with pre- and post-mitigation readings, the system design, the fan specs, the warranty, and the RC202 license stamp. This is the document your buyer's agent, lender, or county inspector will want.

Cambridge sits in the Appalachian Plateau, where uranium-bearing shale and fractured sandstone push radon gas steadily into basement air. Homes throughout Guernsey County — from the older brick two-stories near Cambridge City Hall and the Guernsey County Courthouse to the newer subdivisions out toward Salt Fork State Park — show elevated readings at a rate that consistently outpaces the national average.

We've mitigated homes near Cambridge City Park, in the neighborhoods off Clark Street and Steubenville Avenue, along Wills Creek, and in rural properties between Cambridge and Byesville. Each foundation tells a different story. A 1920s home near Wheeling Avenue with a fieldstone basement requires different suction-point planning than a 2005 split-level with a poured concrete slab off Southgate Parkway. We adjust the design — we don't run the same system on every house.

For Cambridge real-estate professionals: we know the local pace. Inspection contingencies in this market typically run 10 to 14 days, and we've built our Closing-Date Radon Service around that window. Agents at brokerages throughout Guernsey and Muskingum counties refer their elevated-radon clients to us specifically because we won't blow up their timeline.

For commercial clients: we serve apartment owners across Cambridge, healthcare facilities, and educational properties throughout the Rolling Hills and East Guernsey school districts. The RC202 license covers all of these property classes — and most of our regional competitors aren't equipped to handle anything larger than a single-family home.

One of the most common complaints we hear from Cambridge homeowners is that they called three companies and couldn't get a straight number out of any of them. Here's the straight number.

• Standard single-family home (poured basement, one suction point): typically $1,295 – $1,795
• Complex foundation (multiple suction points, block walls, crawlspace combo): $1,895 – $2,795
• Sub-membrane depressurization for crawlspaces: $2,200 – $3,400
• Commercial / multifamily / school: quoted per engineered design after site walk
• EPA-aligned real-estate radon test: $145 – $195

Final pricing depends on your foundation, the routing path, and fan sizing. We provide a fixed quote — not a range — after the diagnostic visit. Financing is available on qualifying mitigation projects.
