Radon Mitigation Continental OH | RC202 Licensed Pros

Continental sits in Putnam County, in a part of northwest Ohio where the EPA's radon zone map and Ohio Department of Health county data consistently show elevated indoor radon readings. The bedrock and glacial till under this stretch of the state release radon gas that seeps through basement floor cracks, sump pits, and slab penetrations. If your home inspector or a private test handed you a number above 4.0 pCi/L, that's not unusual for this part of Ohio — and it's not a reason to panic. It's a solvable engineering problem.

Radon Eliminator is an Ohio-licensed radon mitigation contractor (Ohio Mitigation License RC202) serving Continental and the surrounding Putnam, Henry, Paulding, and Defiance County communities. We install permanent active sub-slab depressurization systems — the EPA-recommended method — and we time the work around real-estate closings, not the other way around.

Most calls we take from Continental fall into three buckets: a seller whose buyer's agent just requested a radon test, a buyer reviewing an inspection report that flagged 5.1 or 7.8 pCi/L, and a homeowner who tested out of curiosity and didn't like the result. Whichever bucket you're in, the fix is the same engineering: a sealed suction point under the slab, a properly sized fan, a discharge stack routed to code, and a post-install re-test that proves the number dropped below 4.0 pCi/L.

There are contractors who swap fans. There are handymen who run PVC. And then there are licensed Ohio radon professionals who design systems that pass a post-mitigation re-test the first time. Here's what separates us in the Continental market:

• Ohio License RC202 — We lead with our license number because Ohio law requires it for any mitigation work performed for compensation. Ask any contractor for their RC number before you sign. Many can't produce one.
• Closing-deadline turnaround — Most Continental real-estate jobs are scheduled and installed within 5 to 7 business days of your call. When a closing is tight, we'll tell you up front whether we can hit it, not after the deposit clears.
• Permanent, code-compliant systems — Every install meets ANSI/AARST standards and Ohio Department of Health requirements. That matters at re-test and matters again when you sell the home later.
• Multi-vertical credibility — We mitigate radon in Ohio schools, apartment buildings, and commercial properties. The same engineering team that satisfies a school district's compliance officer is the team designing the system in your Continental basement.
• Transparent pricing — One quote, in writing, with the fan model, pipe routing, sealing scope, and re-test included. No mid-job upcharges.
• Discreet exterior routing — We plan stack placement so the discharge isn't sitting on the front elevation of your home. Curb appeal isn't an afterthought; it's part of the design conversation.

We handle the full radon problem under one license, one phone number, and one warranty. The services below are the ones Continental customers request most.

Short-term continuous radon monitors deployed for the 48-hour window required by EPA protocol and accepted by Ohio real-estate transactions. Results delivered same-day after pickup, with a written report your agent, lender, and buyer can rely on. Ideal for pre-listing diligence, post-mitigation verification, and buyer-requested testing during inspection contingency.

The standard of care for finished and unfinished basements in Continental. We core a suction point through the slab, install a sealed PVC riser, a properly sized inline radon fan rated for Ohio's humidity, and a discharge stack routed above the eave per code. A U-tube manometer is mounted at eye level so you can verify the system is running at a glance.

Many older homes around Continental and along the Auglaize River corridor have partial crawlspaces. We install reinforced vapor barriers sealed to the foundation walls with a suction point underneath — the same depressurization principle adapted for dirt or gravel floors.

Multi-suction-point designs for larger footprints, including Ohio multifamily properties subject to HUD radon requirements and schools subject to district policy. We provide stamped diagnostic reports, sealed building plans, and post-install clearance testing acceptable to compliance officers and lenders.

Every residential install includes a post-mitigation re-test. If the number isn't below 4.0 pCi/L, we modify the system at no charge until it is. Fans carry a five-year manufacturer warranty; our workmanship warranty covers the system installation itself.

The process is the same whether you're racing a closing date or just want the gas out of your house. We've refined it to five steps:

1. Phone diagnostic (15 minutes). We ask for your test result, foundation type, basement layout, and timeline. From that, we can usually quote a price range over the phone before any visit.
2. On-site diagnostic and design. A licensed technician evaluates slab condition, sump configuration, drain-tile presence, and the best discreet routing for the discharge stack. You get a written, fixed-price quote before anyone drills.
3. Installation (typically one day). Most Continental single-family installs are completed in 4 to 6 hours. Slab coring, sealing, fan mounting, electrical tie-in, manometer install, and exterior stack are all handled by our crew.
4. Post-mitigation re-test. We deploy a continuous radon monitor for 48 hours after the system has run for at least 24. Results go to you, your agent, and (if applicable) the buyer's agent in writing.
5. Closeout package. System diagram, fan model and serial, warranty documents, and the re-test report — everything an appraiser, buyer, or future buyer will ever ask for.

Continental homeowners ask about price first, and they should. Here's how it actually breaks down for this market:

• Standard basement system (interior suction, exterior stack): typically $1,395 – $1,795
• Basement with finished ceiling or complex routing: $1,795 – $2,395
• Crawlspace sub-membrane system: $2,195 – $2,995 depending on square footage
• Multi-suction-point or combination systems: quoted on-site after diagnostic
• Pre- or post-mitigation radon testing: $145 – $195 per location

Every quote includes the fan, all PVC, sealing of accessible slab penetrations, electrical connection, manometer, post-install re-test, and the closeout documentation package. Financing is available for homeowners who want to roll the cost into a longer payment window — useful when the mitigation hits during an already expensive moving month.

Continental is a tight Putnam County village along the Auglaize River, with housing stock that ranges from late-1800s farmhouses on the outskirts toward Dupont and Melrose, to mid-century homes near Continental Schools, to newer builds on the edges of Main Street and SR-613. Each of those eras built basements differently, and each needs a slightly different mitigation approach:

• Older homes near the river corridor often have stone or block foundations with poured slabs added later. Sealing strategy matters as much as the fan size.
• Mid-century homes around the school district typically have poured concrete basements with interior drain tile — usually the cleanest installs, often under $1,500.
• Newer builds on the village's west and south edges often have passive radon stubs from the builder. We can frequently activate those passive systems by adding a fan and rerouting the discharge, which is faster and cheaper than a full new install.

We also serve Ottawa, Leipsic, Defiance, Napoleon, Paulding, Hicksville, and the rest of northwest Ohio from our regional service area. Continental sits within our standard same-week scheduling window. If your closing is in Putnam County and your radon number is the only thing standing between you and the title company, call us first.

A high radon test shouldn't kill a deal. We work directly with listing agents, buyer's agents, and home inspectors across northwest Ohio to keep transactions moving. Inspectors who refer radon work to Radon Eliminator are enrolled in our inspector referral program, which includes priority scheduling for your clients and a named special offer for repeat referrals. Agents get plain-English explanations they can forward to nervous buyers, fixed turnaround commitments tied to the closing date, and post-mitigation reports formatted for transaction files.

If you're an inspector or agent in Continental, Ottawa, or anywhere in Putnam County and you want to talk about the referral program, ask for it by name when you call.
