Radon Mitigation Gordon OH | Licensed RC202 Pros

If your inspection report came back at 4.2 pCi/L, 7.1, or 22, and your closing is in two weeks, you need a Radon Mitigation Gordon OH contractor that actually answers the phone, holds an active Ohio Mitigation License (RC202), and can install a permanent system before the title company calls. That is exactly what Radon Eliminator does in Gordon and across Darke County.

Ohio has one of the highest indoor radon exposure levels in the United States. The Ohio Department of Health classifies most of western Ohio — including Darke County and the Gordon area — as Zone 1, the highest radon potential zone, with predicted average indoor levels above 4.0 pCi/L. That is not marketing copy. That is the EPA county-level map. It means radon in Gordon homes is not a rare event; it is the default condition that has to be engineered out.

We install sub-slab depressurization systems sized to your foundation, sealed at every entry point, vented above the roofline per EPA Protocol, and verified with a post-mitigation radon measurement. When we leave, you have a number under 4.0 pCi/L in writing — and the documentation your buyer, lender, or school board needs.

• Ohio Mitigation License RC202 — stated upfront, on every quote, on every permit
• EPA-aligned testing protocols — 48-hour closed-house, charcoal or CRM
• Closing-Date Radon Service — testing and mitigation timed to your contract deadline
• Permanent, code-compliant systems — not a fan on a wall, an engineered solution
• Post-mitigation verification — documented result under the EPA action level

Most radon shops in the region treat real-estate-deadline jobs as an inconvenience. We built our schedule around them. When a Gordon agent calls Monday morning with a Friday closing, we have a same-week install slot reserved for exactly that scenario.

Licensed Where It Counts

Ohio law requires anyone testing or mitigating radon for compensation to hold a license issued by the Ohio Department of Health. Our mitigation license number is RC202. If a contractor will not give you a license number, they cannot legally pull a radon mitigation permit on your Gordon home — and their work will not stand up in a real-estate disclosure or a re-test.

Multi-Vertical Experience

We are not a single-family-only outfit. We mitigate radon in:

• Single-family homes across Gordon, Greenville, Versailles, and the rest of Darke County
• Apartment complexes and multi-family buildings (ANSI/AARST MAMF protocol)
• Schools and daycare facilities (ANSI/AARST MS-PMD)
• Commercial buildings and office spaces (ANSI/AARST MALB)

If you own an apartment building on the edge of Gordon or manage a school facility in the district, you are legally on the hook for radon levels. We are one of the few Ohio contractors who actually do that work.

Straight Pricing, Not Bait-and-Switch

The most common complaint we hear from Gordon homeowners is, "I called three companies and none of them would give me a straight price." Most Radon Mitigation Gordon OH installations on a standard basement or slab-on-grade home fall between $1,200 and $1,800. Crawl spaces, multiple foundation types, and post-tension slabs run higher because they require more material and labor. We tell you which category your house falls into before we show up.

Our Gordon service area covers the full radon lifecycle — from the first test through long-term system monitoring. Every service below is performed under our RC202 license by trained technicians, not subcontracted out.

Residential Radon Testing

EPA-protocol short-term testing (48-hour closed-house) for real-estate transactions, and long-term testing for homeowners who want a true annual average. We use continuous radon monitors (CRMs) for closing-date jobs because the data is hour-by-hour and tamper-evident — a charcoal kit is not defensible if the buyer's agent challenges the result.

Residential Radon Mitigation System Installation

Sub-slab depressurization is the gold standard for Gordon homes built on basements or slabs. We core through the slab, install a sealed suction point, route schedule-40 PVC up through a chase or exterior wall, mount a properly sized radon fan above the living space, and terminate above the roofline at least 10 feet from any opening. Crawl-space homes get a sub-membrane depressurization system with sealed 6-mil vapor barrier.

Commercial and Multi-Family Mitigation

Commercial radon mitigation in Gordon follows ANSI/AARST MALB and MAMF standards — different fan sizing, different diagnostic protocols, different documentation. We handle apartment buildings, professional offices, and warehouses with conditioned floor space.

School and Daycare Mitigation

Ohio schools are required to test, and elevated results require a licensed mitigator. We work directly with facilities directors and follow ANSI/AARST MS-PMD for design, installation, and post-mitigation verification.

System Diagnosis and Upgrades

Inherited a Gordon home with a 1990s radon fan that's loud, leaking, or simply not pulling the level down? We diagnose existing systems with a manometer reading, smoke testing, and a fresh radon measurement, then recommend a targeted upgrade — usually a new fan, sealed suction points, or an additional pipe run.

Post-Mitigation Testing

Every install gets a post-mitigation test, run a minimum of 24 hours after the system has been operating, with results delivered in writing. If we are not under 4.0 pCi/L, we are not done.

Whether you are a homeowner on Main Street or an agent managing a closing off State Route 127, the process is the same — predictable, documented, and timed to your deadline.

Step 1: Phone Consultation and Quote

Call us and tell us the test result, the foundation type, and the closing date if there is one. Most quotes are issued the same day. No high-pressure sales visit required.

Step 2: On-Site Diagnostic

For complex foundations or commercial buildings, we perform a sub-slab communication test before installation. This tells us exactly how many suction points the building needs — not a guess.

Step 3: System Installation

A standard Gordon residential install takes 4 to 8 hours. We core the slab, run PVC, install the fan, seal all visible foundation cracks and the sump pit, label the system per Ohio code, and install a system performance gauge (U-tube manometer).

Step 4: Post-Mitigation Verification Test

We deploy a CRM for 48 hours, then deliver a signed report showing the post-mitigation radon level. This is the document your title company, buyer, or school board needs.

Step 5: Warranty and System Monitoring

Our installations carry a workmanship warranty, and the fan carries the manufacturer's warranty (typically 5 years). We also offer scheduled re-tests every two years, which is what the EPA recommends for any mitigated home.

Gordon sits in southern Darke County, Ohio, in the middle of the glacial till plain that runs across western Ohio. That soil profile — fractured limestone bedrock beneath silty clay till — is the textbook condition for radon transport into homes. Uranium in the bedrock decays into radium, radium decays into radon gas, and the gas migrates upward through soil pores and foundation cracks.

What that means for Gordon-area homes practically:

• Older farmhouses along Hollansburg-Sampson Road, Gordon-Landis Road, and the rural routes around town often have stone or block foundations with significant air pathways. These homes frequently test in the 8 to 15 pCi/L range.
• Newer construction in subdivisions near Arcanum and Greenville with poured concrete slabs and sump pits still tests high — the sump pit is one of the largest radon entry points in any home.
• Finished basements with bedrooms (very common in Darke County) put occupants directly in the highest-concentration zone of the house. If kids' bedrooms are in the basement, mitigation is not optional.

We serve Gordon and the surrounding communities including Arcanum, Greenville, Versailles, Ansonia, New Madison, Hollansburg, Union City, and Pitsburg. Our trucks are on western Ohio roads daily — we are not driving in from Columbus or Cincinnati to charge you a mobilization fee.
