Radon Mitigation Ottoville OH | Licensed RC202 Pros

Ottoville sits in Putnam County, where glacial till soils and limestone bedrock create some of the highest indoor radon readings in northwest Ohio. The Ohio Department of Health classifies Putnam County as Zone 1 — the highest radon potential designation, with average indoor readings above 4.0 pCi/L. If your inspection report came back at 4.2, 8.1, or even 20+ pCi/L, you are not an outlier in this part of the state. You are the norm.

Radon Eliminator is Ohio's licensed radon mitigation contractor (Ohio Mitigation License RC202) serving Ottoville, Fort Jennings, Kalida, Delphos, and the broader Putnam and Allen County corridor. We install permanent, code-compliant active soil depressurization systems that reduce radon below the EPA action level of 4.0 pCi/L — documented with post-mitigation testing, not guessed at.

We lead with three things competitors bury: our RC202 license number, a firm closing-date timeline, and a clear price before we drive to your property. Call (xxx) xxx-xxxx for same-week service in Ottoville.

Most radon calls in Ottoville come from one of four people: a homeowner who just opened a scary inspection report, a real-estate agent watching a deal slip, a school or apartment owner facing a compliance deadline, or a home inspector who needs a reliable referral partner. We built this company around all four.

• Ohio License RC202, stated upfront. Ohio requires a state-issued radon mitigation license. Many handymen and HVAC outfits in rural counties install fans without one. Ask any contractor for their RC202 number before signing — ours is on every estimate.
• Closing-Date Radon Service. If you have a purchase agreement with a radon contingency, we schedule testing and mitigation around your closing date — not our convenience. Most Ottoville jobs are tested, mitigated, and re-tested within 7–10 business days.
• Guaranteed under 4.0 pCi/L. Every system we install includes post-mitigation testing. If the result isn't below the EPA action level, we modify the system at no charge until it is.
• Multi-vertical experience. Single-family homes, commercial buildings, apartment complexes, and K–12 schools each have different code requirements. We handle all four — most local radon shops only do houses.
• Transparent pricing. Typical Ottoville residential mitigation runs $1,150–$1,850 depending on foundation type (slab, crawl space, full basement) and electrical routing. You get the number on the phone, not a sales pitch in your kitchen.

Radon Eliminator provides full-spectrum professional Radon Mitigation Ottoville OH residents and businesses need to meet EPA and Ohio Department of Health standards.

Active soil depressurization (ASD) is the gold-standard mitigation method for Ottoville homes. We install a sealed PVC suction point through the slab or sub-membrane, route piping up through a chase or along an exterior wall, and mount a calibrated radon fan (typically a Radonaway RP145 or GP501) in an unconditioned space. A U-tube manometer mounted at eye level lets you verify the system is running, every day, for the life of the home.

We provide 48-hour continuous radon monitor (CRM) testing that meets ANSI/AARST MAH-2019 and MAMF-2017 protocols — the standards required for real-estate transactions and federally backed loans. Results are emailed as a tamper-resistant PDF with hour-by-hour data, suitable for delivery to lenders, buyers, sellers, and attorneys.

Ohio Revised Code requires schools and licensed childcare facilities to test for radon, and HUD requires testing on most multifamily transactions. We design and install sub-slab depressurization systems for buildings up to 100,000+ sq ft, including engineered drawings stamped where required, multi-fan configurations, and BAS-integrated monitoring for property managers in Ottoville, Delphos, and Lima.

Bought a home in Ottoville with an existing mitigation system? Half the systems we inspect were installed by unlicensed contractors and are either undersized, miswired, or venting into attics (a code violation). We perform diagnostic testing, fan static-pressure measurement, and full code review — then quote any repairs needed to bring the system back under 4.0 pCi/L.

Every new install includes a follow-up 48-hour test, performed at least 24 hours after the fan has been running continuously, per EPA protocol. You receive a signed, dated report showing the final pCi/L reading. That document is what banks, buyers, and insurance carriers actually want to see.

Speed matters when a closing is on the line. Here is exactly how a Radon Mitigation Ottoville project runs from first call to final report.

1. Phone consultation and quote (Day 0). Tell us the foundation type, square footage, and your initial test result. We quote within the call — no in-home sales visit required.
2. On-site diagnostic visit (Day 1–2). Our licensed technician walks the property, identifies the best suction point, plans the pipe route, and confirms the price in writing.
3. System installation (Day 3–5). Most Ottoville homes are installed in 4–8 hours. We seal sump pits, expansion joints, and visible slab cracks; install PVC piping, the radon fan, electrical disconnect, and manometer; and label the system per ANSI/AARST RMS-LB-2018.
4. Post-mitigation testing (Day 6–8). A calibrated continuous radon monitor runs in the lowest livable area for 48 hours.
5. Final report and warranty (Day 9–10). You receive the post-test PDF, a system warranty (5 years on installation, manufacturer warranty on the fan), and documentation suitable for closing.

Ottoville is a tight-knit village in Monterey Township, anchored by Immaculate Conception Church and surrounded by some of the most productive farmland in Putnam County. It is also sitting on top of the Maumee Lobe glacial deposits — a mix of clay-rich till and fractured carbonate bedrock that releases radon gas through soil pore spaces year-round.

We've tested homes from the village center near North Canal Street and West Third Street out to the rural ag properties along State Route 224 and Road 16J. Older farmhouses with fieldstone or block foundations frequently test in the 8–15 pCi/L range. Newer slab-on-grade builds in the subdivisions north of town often test 5–9 pCi/L. Even tightly sealed homes built in the last decade are not immune — in fact, modern air-sealing makes radon accumulation worse, not better.

We also serve the surrounding Putnam County communities: Fort Jennings, Kalida, Cloverdale, Continental, Leipsic, Pandora, and Columbus Grove. For real-estate testing tied to closings in Delphos, Lima, Van Wert, or Defiance, we run the same closing-date schedule. Our service area extends across Ohio — including Cleveland, Columbus, Canton, and our home base in Akron — but our Ottoville-area technicians live within a 45-minute drive.

If you are searching for the best Radon Mitigation Ottoville contractor, the top Radon Mitigation Ottoville OH provider, or simply Radon Mitigation near me, the differentiator in this market is licensure, documentation, and timeline — not who has the cheapest fan.
