Commercial Radon Services Dunkirk OH | Licensed RC202

Ohio has some of the highest indoor radon levels in the United States. Hardin County sits squarely inside EPA Radon Zone 1 — the highest-risk classification — meaning every commercial building in Dunkirk has a statistically elevated chance of testing above the EPA action level of 4.0 pCi/L. For a property owner, a school administrator, or a real-estate investor, that's not a theoretical problem. It's a compliance, liability, and transaction problem.

Commercial Radon Services in Dunkirk, OH is what Radon Eliminator does every day. We are licensed under Ohio Mitigation License RC202, we follow ANSI/AARST CC-1000 and MAMF protocols for large-building work, and we install permanent, code-compliant systems that hold up to inspector scrutiny, lender review, and tenant lawsuits. We are not an HVAC company that also dabbles in radon — radon is the entire business.

Whether you own a multi-tenant office building near State Route 235, manage an apartment complex serving Dunkirk's workforce, oversee facilities for the Hardin Northern Local Schools district, or you're closing on a commercial property and the buyer's inspection just flagged elevated radon — we are the team to call. Phone: (000) 000-0000.

Most radon companies in northwest Ohio are small residential operators. That's fine for a single-family home in a suburb of Lima. It is not fine for a 40-unit apartment building, a school wing, or a commercial closing where the lender needs documentation before funding. Here is what separates us:

• Ohio License RC202 — published, verifiable, and held by the team actually doing the work in Dunkirk. Not a subcontractor's license borrowed for the paperwork.
• Multi-building protocols — we test and mitigate under ANSI/AARST CC-1000 (commercial), MAMF (multifamily), and MA-MFLB (large buildings). Few competitors in the region are operationally capable of this scope.
• Closing-deadline scheduling — when a real-estate transaction is on the clock, we work to the closing date. Our promise to agents and buyers: we won't blow up your closing.
• Transparent pricing — we quote in writing after a site assessment. No "call for a price" runaround. Commercial mitigation in Dunkirk typically ranges from $2,800 for a small standalone building up to $25,000+ for multi-riser apartment systems, depending on footprint, sub-slab conditions, and HVAC integration.
• Post-mitigation verification — every job ends with a follow-up test and a documentation packet you can hand to a buyer, a tenant, a lender, or the Ohio Department of Health.

That's the short version. The longer version is that we built the company specifically for the gap in the Ohio market: licensed, fast, code-compliant commercial radon work with paperwork that survives an underwriter's review.

We serve five commercial categories in Dunkirk and the surrounding Hardin County area:

• Office and retail buildings — single- and multi-tenant, slab-on-grade and basement construction
• Apartment complexes and multifamily housing — including HUD-financed and LIHTC properties with federal radon disclosure obligations
• Schools and daycare facilities — including ODE-aligned testing cycles for K-12 buildings
• Industrial and warehouse facilities — including buildings with sub-slab utility tunnels or vapor barriers
• Commercial real-estate transactions — pre-listing testing, due-diligence testing, and pre-close mitigation

A commercial property is not a scaled-up house. The testing protocols, mitigation design, equipment, and documentation are all different. Here is what we deliver:

We deploy continuous radon monitors (CRMs) and/or charcoal canisters depending on the building type and the deadline. Test placement follows ANSI/AARST MAMF for multifamily and CC-1000 for commercial — that means one device per ground-contact unit in apartments, and grid-based placement in open commercial floor plates. Results in as little as 48 hours when the closing or compliance clock demands it.

Before designing a mitigation system for a building larger than a single-family home, we run a diagnostic survey: pressure-field extension (PFE) testing, sub-slab communication tests, and soil-gas analysis. This tells us exactly how many suction points the building needs and where to put them — so you don't overpay for an oversized system or under-build one that fails verification.

The standard mitigation method for commercial buildings is ASD — sub-slab depressurization with commercial-grade radon fans, sealed risers, and exterior discharge above the roofline per code. We design each system to the specific building, integrate it with existing HVAC where required, and label every component for future inspection. Systems are warrantied and built for decades of service.

In buildings with complex HVAC — variable air volume systems, makeup air units, or pressurized stairwells — radon mitigation has to coordinate with the mechanical design. We work alongside your facility's mechanical contractor or engineer of record so the radon system doesn't fight the HVAC or create new pressure problems.

Every commercial job closes with a post-mitigation test and a documentation packet: pre-test results, system design drawings, fan specs, manometer readings, post-test results, RC202 license documentation, and a warranty letter. This is the packet you hand to your buyer's attorney, your lender, the school board, or HUD.

We've refined this process across hundreds of Ohio commercial jobs. Here is exactly what happens when you hire us for professional Commercial Radon Services in Dunkirk, OH:

1. Discovery call (same day). We learn the building type, square footage, deadline, and whether this is a transaction or a compliance project. You get a preliminary cost range on the phone — not after a week of silence.
2. Site assessment and written quote (24–72 hours). An RC202-licensed technician walks the building, reviews any prior test data, and delivers a fixed-price proposal.
3. Testing or pre-mitigation diagnostics (2–4 days). CRM or canister testing per ANSI/AARST protocols. For known-elevated buildings going straight to mitigation, we skip ahead.
4. Mitigation system installation (1–5 days). Most commercial systems install in a single day per riser. Multifamily and school buildings may run a full week depending on scope.
5. Verification, documentation, and handoff. Post-mitigation test, full document packet delivered to you (and your buyer, lender, or board), and the system is yours — with warranty and ongoing service available.

For real-estate transactions, we routinely complete test-to-mitigated-and-verified in under 10 business days. That's the difference between closing on time and watching a buyer walk.

Dunkirk sits in the northwestern corner of Hardin County, surrounded by the glacial till and limestone-rich soils that characterize this part of Ohio. That geology — combined with the area's high water table and the prevalence of basement and slab-on-grade construction in older Village properties along Main Street and the side streets off SR-235 — creates ideal conditions for radon entry. The Ohio Department of Health's county-level data has consistently shown Hardin County homes and buildings testing above 4.0 pCi/L at rates well above the national average.

We serve commercial property owners throughout the area: from the small business corridor in downtown Dunkirk, to the agricultural and light-industrial properties along the rail line, to the school facilities serving the Hardin Northern district, to investment properties in the surrounding villages of Forest, Dola, and Patterson. We also handle work in Kenton, Ada, Findlay, and across the I-75 corridor for clients with multi-property portfolios.

If you are a real-estate professional working Dunkirk and the surrounding Hardin County market, ask us about our home inspector and Realtor referral program. We have a named Special Offer for referring partners — because the agents and inspectors who send us their tough deals deserve to be rewarded, not nickel-and-dimed.

One of the most common frustrations we hear: "Every radon company wants me to call for a price." We don't operate that way. Here are real-world ranges for affordable Commercial Radon Services in Dunkirk, OH:
