If your inspection report just flagged elevated radon and you are scheduled to close in two weeks, you need a contractor who works on your timeline — not theirs. Radon Eliminator is a licensed Ohio radon mitigation company (Ohio Mitigation License RC202) serving Calcutta, OH and the greater Columbiana County region. We install permanent, code-compliant radon mitigation systems and provide EPA-aligned post-mitigation testing that documents your home below the EPA action level of 4.0 pCi/L.

Calcutta sits in eastern Ohio's Appalachian foothills, where uranium-bearing shale and glacial till create some of the highest residential radon readings in the state. Ohio has one of the highest radon exposure levels in the United States, and Columbiana County properties — especially older homes with basements, slab-on-grade ranches, and crawlspaces — routinely test above 4.0 pCi/L. That is not a scare tactic. That is the geology under your foundation.

We are not a handyman with a fan. We are full-time radon professionals who do nothing but test and mitigate. Every install in Calcutta is engineered to ASD (active soil depressurization) standards, sealed at every entry point, and verified with a follow-up test before we hand over paperwork.

Call (800) 277-2366 for same-week scheduling, or request a written quote online.

Most Calcutta homeowners calling us are in one of three situations: a real-estate transaction with a tight closing date, a property owner who finally tested and got a number above 4.0 pCi/L, or a commercial/apartment owner facing a tenant complaint or compliance review. Here is what separates us from the other names you will find searching for the best radon mitigation Calcutta has available:

• Ohio License RC202, stated upfront. Ask any competitor for their license number. If they hesitate, you have your answer. Our RC202 mitigation license is required by Ohio Department of Health for anyone installing radon systems — and we lead with it.
• Closing-Date Radon Service. We productize real-estate-deadline jobs. Test, mitigate, and re-test inside your purchase contract window. Most Calcutta closings we touch are completed in 7–10 business days from the first call.
• EPA-aligned testing protocols. Continuous radon monitors (CRMs) and approved short-term test devices, with documented chain of custody — defensible if a buyer's agent or attorney asks.
• Multi-vertical expertise. Single-family homes, commercial buildings, apartment complexes, and K-12 schools. Most local shops only do houses. We have the protocols and insurance for larger Ohio properties.
• Guaranteed results under 4.0 pCi/L. If post-mitigation testing does not show a reduction below the EPA action level, we modify the system at no additional cost.
• Clear, written pricing. No vague phone quotes. You get a fixed number before we touch your home.

We offer a complete radon mitigation services Calcutta OH package — from initial diagnostic test to final clearance documentation. Here is what we install and certify:

The gold-standard radon mitigation system, and the design we install in roughly 90% of Calcutta homes. A sealed PVC suction pipe is set through the slab or sub-membrane, routed to an exterior fan, and vented above the roofline. Properly designed ASD systems routinely drop readings from 8–15 pCi/L down to under 1.0 pCi/L.

Many older Calcutta homes off St. Clair Avenue and through the rural stretches toward East Liverpool have crawlspaces. We install heavy-mil vapor barrier, seal every seam and penetration, and tie the membrane into a depressurization fan — eliminating the radon entry path the dirt floor creates.

Pre-purchase testing, post-mitigation clearance testing, and long-term monitoring. We use continuous radon monitors that log hourly readings — far more defensible in a real-estate negotiation than a passive charcoal canister.

Multi-family buildings and commercial properties in Calcutta and surrounding Columbiana County require multi-point ASD designs, often with multiple fans and balanced flow zones. We handle the engineering, permit coordination, and tenant communication. Property managers in Ohio are legally responsible for indoor air quality — we keep you on the right side of that obligation.

If you are a Calcutta-area home inspector, our partner program gives your clients priority scheduling, a published referral incentive, and clean reports you can attach to your inspection package. Email us to enroll.

Every professional Radon Mitigation Calcutta OH project we run follows the same documented sequence. No improvisation, no surprises.

1. Diagnostic Test & Site Survey. We measure baseline radon levels with a continuous monitor (48–72 hours) and walk the foundation. We identify slab cracks, sump pits, drain tile, and air-handler placement — all data that drives the system design.
2. Custom System Design. Suction-point location, pipe routing, fan sizing (Fantech, RadonAway, or equivalent), and exterior discharge point are mapped before install day. You see a written scope and a fixed price.
3. Code-Compliant Installation. Most Calcutta single-family installations are completed in 4–8 hours. We core the slab, set the suction pipe, seal foundation penetrations with polyurethane, mount the fan outside (never in a living space — that is code), install the U-tube manometer, and label the system per Ohio requirements.
4. Post-Mitigation Clearance Test. A second continuous-monitor test (minimum 48 hours, started no sooner than 24 hours after activation) verifies the reduction. You receive a signed report showing pre- and post-mitigation readings — the document your buyer, agent, or attorney needs.

Calcutta, OH (ZIP 43920) sits in St. Clair Township, Columbiana County, on the western edge of the Pittsburgh metro reach and the Ohio River valley. The bedrock here is part of the Pennsylvanian-age Conemaugh and Monongahela formations — shales and sandstones with measurable uranium content. As that uranium decays, it produces radium, and radium decays into radon gas, which migrates up through soil and into foundation slabs.

That is not theoretical. EPA places Columbiana County in Radon Zone 1 — the highest-risk designation, predicted average indoor radon screening levels above 4.0 pCi/L. Homes along Bell School Road, near the Calcutta-Smith Ferry corridor, around St. Clair Township Park, and across the older neighborhoods toward East Liverpool consistently test in the 5–12 pCi/L range when we run baseline diagnostics.

We have installed systems in Calcutta, East Liverpool, Wellsville, Lisbon, Salem, Columbiana, and across the Columbus and Akron metros. Whether you are buying a brick ranch off Bell School Road or managing an apartment building near Route 170, the mitigation strategy is engineered to your foundation — not pulled from a generic playbook.
