Radon Mitigation Kalida OH | Licensed RC202 Pros

Putnam County sits squarely inside EPA Radon Zone 1 — the highest-risk classification in the country. Ohio's glacial soils, limestone bedrock, and tight modern construction trap radon at levels that routinely exceed the EPA action threshold of 4.0 pCi/L. If you live in Kalida, your house is statistically more likely to have a radon problem than not.

Radon Eliminator is an Ohio-licensed radon mitigation contractor (Ohio License RC202) serving Kalida, Ottawa, Leipsic, Columbus Grove, and the surrounding Putnam County communities. We install permanent active soil depressurization (ASD) systems engineered to ANSI/AARST standards, then we prove the result with a post-mitigation test you can hand to a buyer, lender, or school board.

For Radon Mitigation Kalida OH, that combination — license, EPA-aligned protocol, and documented post-mitigation numbers — is what separates a defensible installation from a fan bolted to a wall.

• Ohio License RC202 stated on every quote, invoice, and system label
• Closing-Date Radon Service for real-estate transactions — testing and mitigation scheduled around your closing date, not ours
• Guaranteed under 4.0 pCi/L on every residential install, verified by post-mitigation testing
• Multi-vertical experience: single-family homes, apartment complexes, commercial buildings, and K–12 schools
• Transparent pricing — written quote before we start, no surprise add-ons

We are not a general contractor that adds radon as a side service. Radon is what we do. Here is exactly what we install, test, and certify in the Kalida area.

For most Kalida homes — ranches in the village, two-stories along Road 5, farmhouses on the section roads outside town — the right solution is a sub-slab depressurization system with an exterior-routed PVC stack and a quiet inline radon fan. We size the fan to your slab area and soil permeability, seal foundation penetrations, and route discharge above the eave per EPA guidance. Typical installs in Kalida finish in one working day.

Larger buildings need a different design — multiple suction points, manifolded piping, often a roof-mounted commercial fan with monitoring. We work with property managers across Putnam County, Allen County, and the wider northwest Ohio region on multi-unit residential, light commercial, and K–12 facilities. Every system is engineered to meet ANSI/AARST CC-1000 standards for non-residential buildings.

We perform short-term continuous radon monitor (CRM) tests for real-estate timelines and long-term passive tests for occupied living spaces. Every test follows EPA Protocol for Radon Measurement and includes a signed report with start/stop times, location photos, and calibrated instrument serial numbers. This is the documentation buyers, sellers, and lenders actually accept.

If your Kalida home already has a mitigation system but recent testing is back above 4.0 pCi/L, we diagnose the failure — dead fan, undersized suction, slab cracks, or improper discharge — and repair or redesign it. Many systems installed during the 2000s building boom in Putnam County are now reaching end of fan life (typically 8–12 years).

A mitigation system without a post-test is just a guess. We return 24–48 hours after the system is energized, place a calibrated continuous monitor in the lowest livable area, and document the resulting radon level. You receive a signed report — the same document we hand to title companies on closing-date jobs.

Every job follows the same five-step protocol — no shortcuts, no improvisation.

1. Phone intake and quote (same day). We ask for your most recent radon test result, basement type (slab, crawl, walk-out), and — if applicable — your closing date. You get a firm written price, usually within an hour.
2. On-site diagnostic visit. We inspect the foundation, identify suction-point candidates, check sump configuration, and confirm electrical access. For most Kalida homes this happens during the install visit; complex jobs get a separate diagnostic.
3. System installation. Core the slab, install the suction pit, run sealed PVC piping up the exterior or through a chase, mount the radon fan above the living space, and install a manometer (U-tube gauge) so you can verify the system is running.
4. Post-mitigation testing. 24 hours after start-up, a calibrated CRM is placed in the lowest livable area for a minimum 48-hour test. Results are emailed as a signed PDF.
5. System label, warranty, and documentation. The system is labeled with our RC202 license number, install date, and fan model. You receive a written workmanship warranty and a copy of all test data for resale or compliance files.

Kalida sits on the flat glacial till plain of northwest Ohio, with shallow soils over carbonate bedrock. That geology — combined with the high water tables common around the Ottawa River watershed — creates the exact conditions that drive radon up through slabs and into basements. Homes built on the limestone shelf running from Kalida toward Glandorf and Ottoville tend to test higher than the county median.

We know the housing stock here: the older homes around Main Street and the school district with field-stone or block foundations, the newer subdivisions north of town with poured-wall basements and passive radon stubs, and the rural farmhouses with stone basements and Michigan-style crawl spaces. Each of these requires a different mitigation approach, and we have installed in all of them.

We serve Kalida and the surrounding communities including Ottawa, Glandorf, Columbus Grove, Leipsic, Continental, Ottoville, Fort Jennings, Cloverdale, and Pandora. Service calls from the Kalida 45853 ZIP are typically scheduled within 3–5 business days, and real-estate closing jobs get priority placement.

If your home inspection just came back with elevated radon and you have a closing date on the calendar, this is the service you need. We have built a separate workflow around real-estate timelines because most contractors treat them as a nuisance.

• Quote within 24 hours of receiving the inspection report
• Install scheduled inside your inspection-response window (typically 5–10 days)
• Post-mitigation test report delivered as a signed PDF your title company will accept
• Direct communication with your agent if you want us to coordinate

Agents and home inspectors throughout Putnam, Allen, Hancock, and Van Wert counties refer Kalida-area clients to us specifically because the paperwork closes deals.

Most single-family residential mitigation systems in Kalida fall in the $1,200 – $1,800 range, depending on foundation type, finish level (do we need to route through finished space?), and suction-point count. Crawl spaces requiring membrane encapsulation typically run $2,200 – $3,800. Commercial, school, and multi-family work is quoted per building after a site visit.

Every quote is written, itemized, and good for 30 days. We do not quote a low number on the phone and then upsell at the truck. If a competitor's price seems unusually low, ask whether their Ohio RC202 license number is on the quote and whether post-mitigation testing is included — those two items are where corners get cut.

Financing is available on residential installations through our third-party lender; ask during your quote call.
