Radon Eliminator provides Radon Mitigation Portsmouth OH homeowners, agents, and commercial property owners can verify in writing. We operate under Ohio Mitigation License RC202 and follow EPA-aligned installation protocols on every job — residential, commercial, school, or apartment complex. When your inspection report flags a radon level above 4.0 pCi/L, you need a contractor who can diagnose the entry pathways, install a sub-slab depressurization system that actually works, and document the post-mitigation result before your closing date.

Scioto County sits in a part of southern Ohio where radon levels frequently exceed the EPA action threshold. The Ohio Department of Health classifies most of the region around Portsmouth, including ZIP codes 45662 and the surrounding river-valley communities, as elevated-risk. Older homes near Boneyfiddle, hillside properties in Sciotoville, and basement-finished houses off US-23 routinely test high because of the limestone-and-shale geology underneath the Ohio River valley. We've engineered systems for every one of these conditions.

Call (330) 525-2785 for same-week scheduling, or request a written quote in under 24 hours. No phone-tag, no vague pricing, no fans sold without a real mitigation design.

Most Portsmouth homeowners calling us are inside a 14- to 30-day real-estate window. They don't need a sales pitch — they need a licensed pro who can be on-site, install a permanent system, and re-test before the bank's deadline. That's the standard we built our company around.

• Ohio License RC202 stated up front. Most local competitors bury or omit their license number. We lead with ours because Ohio law requires it for any radon mitigation work, and your lender's appraiser will ask for it.
• Closing-Date Radon Service. If your purchase contract has a contingency deadline, we schedule the install and the post-mitigation test backward from that date — not from our calendar.
• Documented results under 4.0 pCi/L. Every system we install includes a post-mitigation test and a written report you can hand directly to the buyer, seller, lender, or school board.
• Multi-vertical experience. We mitigate single-family homes, multi-unit apartment buildings, K-12 schools, daycares, and commercial properties across Ohio — a depth most local radon shops simply don't have.
• Transparent pricing. Standard residential mitigation systems in Portsmouth typically run $1,200–$1,800 installed. Complex foundations, sub-membrane crawl spaces, or commercial jobs are quoted in writing before any work begins.

We are a full-scope Radon Mitigation services Portsmouth OH provider. Whether you need a one-time test before closing or a full mitigation system designed for a 40-unit apartment building on Gallia Street, every service below is performed under the same RC202 license and EPA-aligned standard.

The most common solution for Portsmouth homes is active sub-slab depressurization (ASD). We drill through the basement slab, install schedule-40 PVC piping, route it through a code-compliant exhaust path, and seal entry points around sumps, floor cracks, and utility penetrations. The radon fan is mounted exterior or in an attic — never in conditioned living space — per EPA protocol. Systems include a manometer for ongoing performance monitoring.

Ohio law requires public schools and licensed childcare facilities to address elevated radon. Apartment owners and commercial landlords carry liability exposure for any occupied space above 4.0 pCi/L. We design multi-point mitigation systems for slab-on-grade commercial buildings, multi-family properties, and educational facilities throughout Scioto County and the broader Ohio River corridor.

We deploy continuous radon monitors (CRMs) for 48-hour real-estate tests and longer-term protocols for occupancy verification. Results are EPA-aligned, chain-of-custody documented, and delivered as a PDF report acceptable to lenders, attorneys, and school administrators.

Every new system gets a post-mitigation test to confirm levels are below 4.0 pCi/L. We also inspect, diagnose, and upgrade existing radon systems installed by other contractors — common failures we see in Portsmouth include undersized fans, improper exhaust termination, and unsealed sumps. If your manometer reads zero or your levels are still high, we can fix it.

Here is exactly what happens when you hire the best Radon Mitigation Portsmouth team for your home, listing, or commercial property.

1. Step 1 — Diagnostic site visit. A licensed technician walks the foundation, identifies entry pathways, and confirms the best system design. For real-estate clients, this often happens within 48 hours of your call.
2. Step 2 — Written, fixed-price proposal. You receive a documented quote, system diagram, and timeline. No vague estimates, no surprises at the end of the job.
3. Step 3 — System installation. Most residential installs are completed in a single day. Crawl spaces with vapor barrier work and commercial jobs may take 2–3 days.
4. Step 4 — Post-mitigation testing. A 48-hour continuous monitor confirms the system brought levels below 4.0 pCi/L. You receive a signed report suitable for the closing file.
5. Step 5 — Warranty and monitoring. Our installations carry a system warranty, and the manometer gives you a permanent visual check that the fan is performing.

Portsmouth's geology — Ohio River valley sediments layered over fractured limestone and Devonian shale — is one of the more aggressive radon-producing combinations in the state. Ohio has one of the highest radon exposure profiles in the United States, and Scioto County consistently shows elevated readings in homes ranging from historic brick structures in Boneyfiddle to newer subdivisions near Shawnee State University and out toward Wheelersburg.

We've installed systems in neighborhoods across the city: West Portsmouth, Sciotoville, New Boston, the homes lining Grandview Avenue, and rural properties out toward Lucasville and Minford. Each foundation type — block basement, poured wall, crawl space, slab-on-grade — gets a slightly different mitigation design. A cookie-cutter fan installation is exactly how most failed systems happen.

If you are a real-estate agent working a deal in Portsmouth, a home inspector who needs a reliable referral partner, or a property manager responsible for tenant safety, we are the professional Radon Mitigation Portsmouth OH resource you can put in your contacts and trust. We also serve Columbus, Cleveland, Canton, and surrounding Ohio markets through our statewide team.
