You're here because a test came back over 4.0 pCi/L, or a buyer's agent is asking for a radon number before closing. Radon Eliminator handles Radon Mitigation Marengo OH homeowners and real-estate professionals trust to close on time. We are licensed by the Ohio Department of Health under Mitigation License RC202, we follow EPA and ANSI/AARST protocols, and we install permanent, code-compliant systems — not the cheap fan swaps that fail a re-test two weeks after the moving truck leaves.

Marengo sits in Morrow County, an area the Ohio Department of Health classifies as elevated risk for radon. Glacial till soils across central Ohio create the exact subsurface conditions that pull radon gas into basements and crawlspaces. Local averages routinely exceed the EPA action level of 4.0 pCi/L, and we have measured Marengo homes well into double digits. This isn't a scare line — it's a soil-and-geology fact our installers work with every week.

Call 1-800-436-0788 to schedule a Marengo radon assessment, or request a written quote online. Most quotes are returned the same business day.

There are a handful of contractors who will quote radon work in Morrow County. Here is why Marengo homeowners, agents, and inspectors call us first — and what makes us the best Radon Mitigation Marengo option for a transaction-sensitive job.

• Ohio Mitigation License RC202 — printed on every proposal. Many competitors bury their license number or sub the work out. We lead with it.
• Closing-deadline turnaround — most Marengo installs are scheduled within 3–7 days of approval. We treat real-estate timelines as a hard deadline, not a suggestion.
• Flat, written pricing — typical single-family Marengo systems run $1,150–$1,650 installed. No surprise add-ons after the crew arrives.
• Permanent, code-compliant systems — sub-slab depressurization built to ANSI/AARST SGM-SF-2017, with quality fans (RadonAway / Festa), sealed sump lids, U-tube manometers, and exterior discharge above the eave per code.
• Post-mitigation re-test included — we don't just install and leave. We verify the home is below 4.0 pCi/L and hand you documentation your buyer, lender, and underwriter will accept.
• Multi-vertical credibility — we mitigate Ohio schools, apartment complexes, and commercial buildings under the same RC202 license. If a school district trusts us with 600 kids, your Marengo basement is straightforward work.

For agents and inspectors: ask about our referral program. We protect the deal, document everything cleanly, and never make your client feel sold to.

Marengo housing stock varies — older farmhouses with stone foundations along SR-229, newer builds in subdivisions off US-23, manufactured homes, and a growing inventory of small commercial buildings near downtown. We engineer the system to the building, not the other way around.

The gold standard. We core through the basement slab, excavate a suction pit, install schedule-40 PVC, route it discreetly through a utility chase or garage, and vent above the roofline with an inline radon fan. Properly designed ASD systems reduce radon by 85–99%. Most Marengo single-family homes need exactly one suction point.

Many older Marengo homes, especially out toward Mount Gilead and Cardington, have dirt or partial crawlspaces. We install a 12-mil reinforced vapor barrier, seal it to the foundation walls, and tie it into the radon suction stack. This eliminates the radon entry pathway and the moisture problem in one visit.

For real-estate transactions we deploy continuous radon monitors (CRMs) that produce hourly data and a tamper log — the format underwriters and buyer's agents prefer. Standard 48-hour test with results emailed the morning after pickup. Long-term alpha-track tests available for owner-occupants who want annual verification.

Multi-suction-point systems for apartment buildings, daycares, and schools throughout central Ohio. We handle Ohio Department of Health documentation, multi-room CRM placement per ANSI/AARST MAMF and MALB protocols, and phased installs that don't disrupt operations.

Inherited a system from a previous owner? We inspect, re-test, and bring it to current Ohio code. Radon fans typically last 8–12 years; if your manometer reads zero, the fan is done. Same-day swaps available in the Marengo area.

Every Marengo project follows the same disciplined sequence. No improvising, no shortcuts.

1. Free phone consult & written quote. Tell us your pCi/L number, foundation type, and closing date. We send a flat-rate proposal the same day.
2. On-site diagnostic visit. A licensed technician inspects the foundation, identifies suction-point options, and confirms the routing path you'll be happiest with cosmetically.
3. Installation (typically one day). Crew arrives, cores the slab, installs PVC, mounts the fan outdoors or in the attic per code, seals all foundation openings, and labels the system per Ohio rule.
4. Post-mitigation re-test. We deploy a continuous monitor for 48 hours. Goal: below 4.0 pCi/L, with most installs landing under 2.0.
5. Documentation packet. You receive the test report, system warranty, RC202 install certificate, and any paperwork your title company needs. Done.

We've worked on homes from the village center near Marengo Park out through the rural stretches along Old State Road and County Road 26. We've mitigated lakefront properties near Alum Creek Lake, farmhouses bordering Mount Gilead State Park, and newer construction along the US-23 corridor headed toward Delaware and Columbus.

What we've learned about Marengo radon: shallow bedrock and fractured glacial deposits in this part of Morrow County create reliable radon transport paths. Sealed-up modern homes with tight HVAC systems often test higher than drafty older homes — counterintuitive, but consistent. Sump pits without sealed lids are the single most common radon entry point we find in Marengo basements.

Because we serve the broader region — Columbus, Delaware, Mount Vernon, Mansfield, and out to Akron where our shop is based — our Marengo customers get big-city equipment inventory with small-town scheduling flexibility. When a Realtor calls Friday afternoon saying closing is Tuesday, we have the fans, pipe, and crew to make it happen.

That's what makes us the top Radon Mitigation Marengo homeowners recommend after the deal closes — the system works, the paperwork is clean, and the install didn't blow up the timeline.

We publish our pricing because guessing games waste everyone's time. These are typical Marengo ranges for 2024:

• Standard basement ASD system: $1,150 – $1,450
• Basement + slab-on-grade addition: $1,450 – $1,750
• Crawlspace encapsulation + mitigation: $2,200 – $3,800 depending on square footage
• Real-estate radon test (48-hr CRM with report): $150 – $185
• Commercial / multifamily: Quoted per building after site visit

We accept all major cards, offer financing through Wisetack (instant approval, soft credit pull), and can bill at closing through the title company when the seller is covering mitigation as part of negotiations. That's how affordable Radon Mitigation Marengo homeowners actually use the service without delaying closing or draining savings.

If you sell homes or inspect homes in Morrow, Delaware, Knox, or Marion County, you already know radon comes up on roughly 1 in 3 transactions. We make that conversation easy:

• Same-day written quotes you can forward to your client
