Radon Mitigation Urbana OH | Licensed RC202 Pros

If your Urbana home tested above 4.0 pCi/L, you need two things: a licensed Ohio radon contractor and a system that actually drops the number — documented, on paper, before your closing date. Radon Eliminator holds Ohio Mitigation License RC202 and installs permanent, code-compliant Radon Mitigation Urbana OH systems that bring radon below the EPA action level of 4.0 pCi/L. We don't hedge that result. We measure it after installation and hand you the report.

Champaign County sits inside one of the most radon-prone regions in the country. The Ohio Department of Health classifies Champaign County as EPA Zone 1 — the highest predicted indoor radon screening level. That means a typical Urbana home, whether it's a 1920s farmhouse off Scioto Street, a slab-on-grade ranch in the Mosgrove area, or a finished basement near Melvin Miller Park, has a statistically meaningful risk of elevated radon. We've measured it firsthand across the 43078 ZIP code.

Call (937) 360-7745 for same-week assessment, a written quote with no vague language, and an install scheduled around your deadline — not ours.

Most radon shops in central Ohio install fans. We install systems — engineered sub-slab depressurization built to ASTM E2121 standards, inspected, sealed, balanced, and verified by a follow-up test. Here's what separates us in the Urbana market:

• Ohio License RC202 stated upfront. Many competitors bury or omit their license number. Ohio law requires a licensed mitigation specialist for any system install. Ask for the number before you sign anything — ours is RC202.
• Closing-Date Radon Service. If your inspection report flagged radon and you're 7–21 days from closing, we productize that timeline. Testing, install, and post-mitigation verification fit the contract — not the other way around.
• EPA-aligned protocols. Continuous radon monitors, 48-hour closed-house conditions, and ANSI/AARST measurement standards. The number we hand you holds up to lender, buyer, and attorney scrutiny.
• Multi-vertical expertise. We mitigate single-family homes, commercial buildings, apartment complexes, and schools. Property managers in Logan and Champaign counties call us because most local outfits only handle houses.
• Clear, written pricing. Standard residential mitigation systems in Urbana typically run $1,200–$1,950 depending on foundation type, with complex multi-suction-point or commercial jobs quoted on-site. No vague phone estimates that double at the truck.
• Guaranteed result under 4.0 pCi/L. If post-mitigation testing doesn't show a reduction below the EPA action level, we return and modify the system at no additional cost.

We offer the full radon scope for Urbana property owners — from the first short-term test to the final clearance report. Every service is performed by a licensed Ohio radon professional, not a subcontractor.

Active sub-slab depressurization (ASD) is the standard solution for most Urbana homes. We core through the slab, seal the basement or crawlspace envelope, run inert PVC to a code-compliant exterior discharge point above the roofline, and install a UL-listed radon fan sized to your home's substructure. For crawlspaces common in older Urbana farmhouses, we use a sub-membrane depressurization system with sealed 12-mil vapor barrier.

Continuous radon monitors deployed under proper closed-house conditions, with hourly readings, tamper detection, and a signed report acceptable to lenders, agents, and inspectors. Critical for transactions involving FHA, VA, or relocation buyers who require documented radon clearance.

Ohio law and Ohio Department of Health guidance require schools, daycares, and many commercial properties to manage radon risk. We design multi-point systems for apartment buildings, office slabs, and school facilities across Champaign and surrounding counties. Engineered drawings, building-department permits, and post-install verification included.

Every installation includes a follow-up radon measurement after the system has stabilized (minimum 24 hours, standard 48). You receive a written report showing pre- and post-mitigation pCi/L levels — the document your buyer's agent, lender, or building owner will ask for.

Bought an Urbana home with an existing radon system? We diagnose under-performing installs — failed fans, undersized suction points, broken manometers, illegal indoor discharge — and bring the system into ANSI/AARST and Ohio code compliance.

A defensible mitigation isn't just a fan on a pipe. It's a measured process. Here's how the best Radon Mitigation Urbana workflow runs from first call to final report:

1. Phone Triage & Quote (Day 1). You tell us the test result, foundation type, and timeline. We give you a written price range over the phone — typically $1,200–$1,950 for a standard residential system — and book the site visit.
2. Diagnostic Site Visit. Our licensed technician inspects the slab, sump, crawlspace, and existing penetrations. We identify suction-point location, fan size, and discharge routing. You get a final fixed-price proposal before any work starts.
3. System Installation (1 Day, Most Homes). Core drilling, sealing, PVC routing through the rim joist or chase, UL-listed fan mounted in attic or exterior wall, electrical tie-in by licensed electrician, and U-tube manometer installed for ongoing monitoring.
4. Post-Mitigation Test (48 Hours). Continuous monitor deployed in the lowest livable space. We confirm the number is below 4.0 pCi/L — almost always below 2.0 pCi/L on properly designed systems.
5. Documentation Packet. Signed mitigation contract, system diagram, warranty, post-mitigation test report, and Ohio RC202 license documentation. Everything your buyer, lender, or property manager needs.

Urbana's geology is exactly why radon shows up here. The county sits on glacial till and fractured limestone bedrock — both efficient at moving radon gas from uranium-bearing soil into basements, crawlspaces, and slab penetrations. We've installed systems in every common Urbana housing type:

• Historic homes near downtown along Scioto Street, Court Street, and Reynolds Street — stone foundations and dirt crawlspaces that need sub-membrane mitigation.
• Mid-century ranches in neighborhoods around East Lawn Avenue and Patrick Avenue — straightforward sub-slab depressurization, usually one suction point.
• Newer slab-on-grade construction in subdivisions north of US-36 — passive stub systems that need activation with a properly sized fan.
• Rural farmhouses outside city limits toward Mechanicsburg, North Lewisburg, and St. Paris — combined basement-and-crawlspace systems.
• Commercial and institutional buildings serving Urbana University facilities, downtown businesses, and Champaign County schools.

We also serve home buyers and sellers working with inspectors across Champaign, Logan, Clark, and Miami counties. If you're a home inspector who refers radon work, ask about our inspector partner program — published rates, fast turnaround, and clean documentation that protects your reputation.
