Radon Mitigation Glandorf OH | Licensed RC202 Pros

Radon Eliminator is a licensed Ohio radon contractor (Ohio Mitigation License RC202) installing active soil depressurization systems in Glandorf, Ottawa, Kalida, Leipsic, and across Putnam County. If your short-term test or real-estate inspection came back at or above 4.0 pCi/L, you need a mitigation system — not a debate. We build the system, run the discharge piping to code, install the manometer, and re-test to confirm the number dropped.

Putnam County is part of Ohio's high-radon belt. The geology under Glandorf — glacial till over limestone bedrock — is exactly the kind of subsurface that pushes radon gas up through basement slabs, crawlspace floors, sump pits, and slab cracks. That's not marketing language; that's why the EPA classifies most of northwest Ohio as Zone 1, the highest-risk tier.

Call (330) 806-4847 for a clear quote, a scheduled install date, and a post-mitigation test result you can hand to a buyer, an inspector, or a school board.

Most Glandorf homeowners calling us fall into one of three buckets: a real-estate deal flagged elevated radon and closing is in two weeks, a parent saw a county map and realized the kids' bedrooms are in the basement, or a commercial/apartment owner just got a compliance letter. Here's what separates us from a generic contractor with a fan and a drill.

• Ohio License RC202, stated upfront. Most competitors bury their license number on a footer or don't list it at all. We lead with it because Ohio law requires it and your closing attorney will ask for it.
• Closing-Date Radon Service. Real-estate deadlines are not a nuisance — they're a product line. We schedule the install, the post-mitigation test, and the documentation around your closing date, not the other way around.
• EPA-aligned protocols. Continuous radon monitors, 48-hour minimum closed-house test conditions, and post-mitigation verification. The result is defensible if it's ever challenged.
• Multi-vertical experience. Single-family homes, apartment complexes, condominium associations, and K-12 school buildings. Most local radon shops only handle single-family — if you own larger property in Putnam County, we're one of the few Ohio teams who actually do this work at scale.
• Transparent pricing. Standard residential mitigation systems in Glandorf typically run $1,200–$2,200 depending on foundation type (slab, crawlspace, basement, or mixed). You get the number before we show up.
• Home-inspector partner program. If a Glandorf or Ottawa inspector referred you, ask about the inspector-network pricing.

We're not a handyman with a side hustle. Every service below is performed by Ohio-licensed radon professionals under RC202, using EPA-aligned protocols and certified continuous radon monitors.

Active soil depressurization (ASD) is the gold-standard method and what nearly every Glandorf home needs. We core through the slab, seal the suction point, run schedule-40 PVC up through a conditioned chase or the exterior, install a properly sized radon fan (rated for the static pressure of your soil), and discharge above the roofline per EPA and Ohio code. A U-tube manometer is mounted on the visible riser so you and any future buyer can verify the system is running.

Larger buildings need a different design: multiple suction points, balanced sub-slab fields, sometimes sub-membrane systems for crawlspace sections, and HVAC coordination. We've installed systems in apartment complexes, daycare facilities, and Ohio school buildings. If you own a multi-unit property in Glandorf or surrounding Putnam County and you've received a state or insurance notice about radon, call us before you call a general contractor.

Short-term tests (48–96 hours) using continuous radon monitors for real-estate timelines. Long-term alpha-track testing for baseline assessment. Multi-zone testing for buildings with separated foundation types. Every test is delivered with a signed PDF report referencing the EPA action level of 4.0 pCi/L.

The install isn't the deliverable — the post-mitigation number is. After 24 hours of system run-time, we deploy a continuous monitor for a minimum 48-hour closed-house test and provide a written report showing the new radon level. This is what a buyer's agent, lender, or school board will actually ask for.

Bought a Glandorf home with a system already installed? We inspect the manometer, fan amperage, suction point integrity, discharge location, and current radon level. Older systems with undersized fans, improper discharge, or failed seals get upgraded to current code.

Here is the exact sequence for a typical Glandorf mitigation job, from first call to a number under 4.0 pCi/L.

1. Phone diagnosis (same day). We ask about your test result, foundation type, basement layout, and timeline. If you're in a real-estate transaction, we ask for the closing date first.
2. On-site diagnostic (typically 1–3 business days). We perform a sub-slab communication test to determine suction-point placement, evaluate any sumps, and confirm the system design. Written quote in hand before we leave.
3. Installation (one day for most homes). Slab core, sealing, PVC routing, fan installation, electrical, manometer mount, and discharge.
4. Post-mitigation test (48–96 hours later). Continuous monitor deployed in the lowest livable area. Report delivered as a signed PDF.
5. Documentation package. RC202 license confirmation, system warranty, post-mitigation result, and any closing-package paperwork your title company needs.

Total time from call to documented sub-4.0 result: typically 7–10 days. Faster if your closing demands it.

Glandorf is a small village in Ottawa Township with a housing stock that skews toward older farmhouses, mid-century ranches along Main Street and the SR-224 corridor, and newer builds toward Ottawa. Each of these foundation types behaves differently with radon.

The older farmhouses around Glandorf often have fieldstone or block foundations with dirt floor sections in original cellars — these need sub-membrane systems or hybrid designs, not a simple slab depressurization. Mid-century homes typically have poured basements with floor drains and old sump pits, which are major radon entry points and must be sealed properly during installation. Newer construction near Ottawa sometimes has passive radon roughed-in stubs from the builder; we activate and verify those rather than starting from scratch, which often saves the homeowner several hundred dollars.

We also serve Ottawa, Kalida, Leipsic, Columbus Grove, Continental, and Fort Jennings. If you're near St. John the Baptist Church, the Glandorf Park area, or out toward the SR-15 corridor, you're well within our standard service zone — no travel surcharge.

Worth knowing: the Ohio Department of Health reports that more than 40% of homes tested in Putnam County have come back above the EPA action level. This isn't a rare problem in Glandorf. It's the baseline expectation.
