Commercial Radon Services Middleport OH | RC202 Licensed

Radon Eliminator delivers Commercial Radon Services Middleport OH property owners can stake a closing, a lease, or a state inspection on. We are an Ohio-licensed radon mitigation contractor — license number RC202 — and radon is the only thing we do. Not HVAC. Not basement waterproofing. Not foundation work with radon as a sideline. Just EPA-aligned testing and permanent, code-compliant mitigation systems for residential, commercial, apartment, and school properties across Meigs County and the greater Middleport area.

Middleport sits along the Ohio River in a region the U.S. EPA classifies as Zone 1 — the highest radon potential category in the country. The predicted indoor screening level for Meigs County exceeds the EPA action threshold of 4.0 pCi/L. That means commercial buildings, multifamily housing, and older brick structures along South Second Street, Mill Street, and the historic riverfront district are statistically likely to test high. If you own a building here, radon is not a maybe. It is a measurable liability you are responsible for.

Most radon companies in southeastern Ohio are residential-only operators with one truck and a stack of fan boxes. Commercial work — apartment buildings, schools, office complexes, assisted living, industrial — requires a different scope of expertise, equipment, and licensing. Here is what separates us from the generalists:

• Ohio Radon Mitigation License RC202 — published on every proposal, every invoice, and every permit. Verify it on the Ohio Department of Health website before you hire anyone.
• Real-estate transaction speed — we test, design, install, and post-test inside closing windows as tight as 10 business days. We won't blow up your deal.
• Commercial-grade equipment — Radonaway GP501/HP2200 series fans, continuous radon monitors (CRMs) for sub-24-hour quantitative results, and multi-point suction designs for slab-on-grade warehouses and large basement footprints.
• Multi-vertical depth — we are one of the few Ohio contractors equipped for schools (ANSI/AARST MS-MFLB), multifamily housing (ANSI/AARST CC-1000), and commercial buildings (ANSI/AARST RMS-MF). Local handymen cannot legally sign off on this work.
• Transparent, fixed pricing — commercial mitigation quotes are line-itemed: diagnostic, materials, labor, permit, post-mitigation test. No surprise change orders.

That is why agents at the major Middleport-area brokerages, property managers running rentals from Pomeroy to Gallipolis, and school facility directors across the Tri-Valley region keep our number on speed dial.

Every commercial property has a different building envelope, occupancy schedule, and risk profile. Our scope reflects that. Below are the core services we deliver to Middleport businesses, investors, and institutions.

We deploy continuous radon monitors (CRMs) placed according to ANSI/AARST MAMF and MALB protocols — not cheap charcoal canisters. For a 20-unit apartment building in Middleport, that typically means devices in 25% of ground-contact units plus common areas. Results are quantitative, hourly, tamper-evident, and delivered in a signed PDF report you can hand to a lender, buyer, or state regulator.

For Middleport commercial buildings testing above 4.0 pCi/L, we design active soil depressurization systems engineered to the building's specific slab condition, sub-slab aggregate, and HVAC interaction. Most installations include multi-point suction, sealed sump covers, vapor barrier work in crawlspaces, and exterior vent stacks routed above roofline per code. Systems include a manometer, labeled service disconnect, and a written warranty.

Ohio landlords are not legally required to test, but once you know — through a tenant complaint, sale-driven inspection, or insurance audit — your liability clock starts. We handle full-portfolio testing, mitigation roll-outs across multiple buildings, and the documentation property managers need for HUD, RD, LIHTC, and lender compliance.

Public schools in Meigs County and surrounding districts fall under ANSI/AARST MS-MFLB. We coordinate testing during occupied hours, mitigate during breaks, and produce board-ready reports. Our crews are background-checked for school access.

Commercial real estate closings on Middleport storefronts, riverfront properties, and small office buildings often surface radon late in due diligence. We provide 48-hour testing turnaround, 5–10 day mitigation timelines, and direct communication with the buyer's agent, lender, and title company. This is the wedge our clients value most: we close deals on time.

We run the same disciplined sequence on every commercial job — from a four-unit Middleport rental to a regional school district.

1. Site walk and diagnostic (Day 1). A licensed technician walks the building, identifies sub-slab conditions, foundation type, HVAC zones, and existing penetrations. We measure differential pressure and pull a small core sample where appropriate to confirm sub-slab communication.
2. Quantitative testing (Days 2–4). CRMs deployed per AARST protocol. Closed-building conditions enforced and logged. Results delivered with raw hourly data, average pCi/L, and a signed conclusion.
3. System design and fixed-price proposal (Day 5). If mitigation is needed, you get a stamped design, suction-point map, fan model, route, and a single number — not a range.
4. Installation (Days 6–10 typical). Crew arrives in marked trucks, pulls permits, and installs to ANSI/AARST CC-1000 or RMS-LB. Tenants and staff are typically not displaced.
5. Post-mitigation testing and final report (Days 11–14). A second CRM test confirms the system brought levels below 4.0 pCi/L — almost always under 2.0. You receive a closeout packet with warranty, system diagram, and a label affixed to the manometer.

Middleport's housing and commercial stock skews older — a lot of pre-1950 brick, fieldstone foundations, and partial basements cut into the river valley clay. That geology matters. Radon migration here is driven by fractured shale, clay-on-limestone interfaces, and high groundwater near the river. Generic mitigation templates fail in these conditions. We have installed systems on properties near Mill Street, Lincoln Avenue, the Middleport Riverfront Park district, and across the bridge in Mason County, WV — so we know what works on a 1920s commercial block versus a 1980s slab-on-grade warehouse off State Route 7.

We also work the surrounding region: Pomeroy, Racine, Rutland, Tuppers Plains, Gallipolis, and Athens. If you manage a portfolio across southeastern Ohio, you get one contractor, one license number, one set of paperwork.

For real-estate professionals: ask about our home inspector and agent referral program. Inspectors who flag radon on a Middleport-area report can hand the homeowner a named offer that gets the testing and mitigation done before the inspection contingency expires. It protects your transaction and your reputation.

We publish ranges so you can budget honestly. Final price depends on building size, foundation type, and slab condition.

• Commercial radon testing (CRM, per building): $295–$795 for small commercial; portfolio pricing available for apartments and schools.
• Single-family or small commercial mitigation: typically $1,495–$2,495 installed, including post-test.
• Multifamily and large commercial mitigation: $2,800–$9,500+ per building depending on suction points, slab area, and fan staging.
• Schools and institutional: quoted per AARST MS-MFLB scope.

All commercial work includes a workmanship warranty and a system performance guarantee — if post-test exceeds 4.0 pCi/L, we re-engineer at no charge.
