Commercial Radon Services Celina OH | Licensed RC202 Pros

Mercer County sits inside EPA Radon Zone 1 — the highest-risk classification in the United States. Average indoor radon readings across western Ohio routinely test above the EPA action level of 4.0 pCi/L, and commercial buildings with slab-on-grade construction, block foundations, or sub-slab HVAC returns are especially vulnerable. If you own, manage, or are buying commercial property in Celina, you are legally and financially exposed to radon — and that exposure does not go away by ignoring it.

Radon Eliminator provides Commercial Radon Services in Celina OH for office buildings, multi-family apartments, schools, daycares, medical facilities, retail centers, industrial warehouses, and mixed-use real estate. We are licensed by the Ohio Department of Health under Mitigation License RC202 — a credential most local HVAC and basement contractors do not legally hold. Every test we run follows EPA and ANSI/AARST protocols (MAH-2019 for multifamily, MALB-2014 for large buildings, MAMF-2017 for schools). Every mitigation system we install is engineered to drive sub-slab radon levels below 2.0 pCi/L and stay there.

Most radon companies are residential outfits doing commercial work on the side. We are the opposite. Commercial, school, and multifamily mitigation is our core practice — and Celina property owners benefit from that focus in measurable ways.

• Ohio License RC202 — publicly verifiable with the Ohio Department of Health. Required by law for mitigation; rarely held by general contractors.
• ANSI/AARST commercial protocols — we follow the published standards for large buildings (MALB), multifamily (MAH), and schools (MAMF), not residential shortcuts.
• Real-estate transaction speed — 48-hour continuous radon monitor testing, written reports the same day results clear, and mitigation systems installed within 5–10 business days when closings demand it.
• Transparent commercial pricing — published per-test and per-zone pricing with no "call for a quote" runaround. You get a written scope before we mobilize.
• Lifetime-grade workmanship — every system uses commercial-grade radon fans (RadonAway GP, Festa AMG), schedule-40 PVC, and post-mitigation testing included.
• Multi-vertical depth — we are equipped to handle a 4-unit duplex in downtown Celina or a 60-classroom school district campus with the same compliance rigor.

When a Celina apartment owner has 18 units to test before a refinance, or a Celina City Schools building needs district-wide compliance documentation, calling the company that "also does radon" is not the move. Calling Radon Eliminator is.

For commercial buildings over 2,000 sq ft, the EPA does not allow a single short-term test to represent the whole structure. We deploy continuous radon monitors (CRMs) across statistically valid zones — typically one device per 2,000 sq ft of ground-contact space — and run a minimum 48-hour test under closed-building conditions. Results come back as a sealed PDF report with device serial numbers, calibration dates, and a licensed mitigation specialist's signature. Lenders, insurers, and Ohio DOH accept these reports without question.

HUD-financed properties, LIHTC properties, and most lender refinances on Celina apartment buildings now require radon testing of 100% of ground-contact units — not a sampling. We handle scheduling with tenants, supply tamper-evident devices, and turn around full-property reports quickly enough to keep your refinance or sale on schedule. We have run this exact process on properties from Grand Lake St. Marys waterfront condos to multi-building apartment communities off Havemann Road.

When a Celina commercial building tests above 4.0 pCi/L, we engineer a sub-slab depressurization (SSD) system sized to the building footprint. That means pressure-field extension diagnostics, properly sized commercial radon fans, sealed sumps and slab penetrations, U-tube manometers on every active suction point, and exhaust routed above the roofline per ANSI/AARST RMS-LB. Every system is followed by a 48-hour post-mitigation test to prove it works — included, not extra.

Ohio schools and licensed childcare facilities have a duty of care that the law takes seriously. We run district-wide testing programs that follow the EPA's school protocol — every frequently occupied ground-contact room tested, documented, and re-tested every two years or after major HVAC changes. Mitigation in occupied schools is scheduled around the academic calendar, with low-noise commercial fans selected so classroom learning is never interrupted.

If you are a commercial real-estate broker, buyer, or seller mid-transaction in Celina, we understand the clock. Our standard commercial transaction package includes deployment within 48–72 hours of contract signing, the required 48-hour closed-building test, a sealed report delivered electronically, and — if mitigation is required — a binding written quote with an install date that fits inside your due diligence window. We do not blow up closings.

Here is exactly how a commercial radon project runs from first call to final report. No surprises, no scope creep.

1. Site assessment & written scope (Day 1–2). We review building plans, square footage, foundation type, HVAC zoning, and intended use. You receive a written scope with device count, test duration, and pricing before any work is scheduled.
2. Closed-building testing (Day 3–5). Continuous radon monitors are deployed under the 12-hour closed-building condition required by EPA. Devices run 48 hours minimum. We coordinate with property managers and tenants on access.
3. Sealed report & recommendation (Day 5–6). You receive a PDF report signed by a licensed Ohio mitigation specialist (RC202), with zone-by-zone pCi/L results and a clear pass/fail against the 4.0 pCi/L action level.
4. Mitigation design & install (if needed, Day 7–14). Pressure-field diagnostics, system design, permit coordination if required, and installation by our in-house crew. No subcontractors.
5. Post-mitigation verification (Day 15–17). A second 48-hour CRM test confirms the system has driven radon below the action level. The final closeout package includes warranty documentation and maintenance instructions.

Celina sits on glacial till soils along the southern shore of Grand Lake St. Marys, with a high water table and shallow bedrock — geology that pushes radon-laden soil gas upward into commercial slabs more aggressively than in many parts of Ohio. We have tested and mitigated properties throughout the area, from the historic downtown commercial corridor along North Main Street and Fayette Street, to industrial and warehouse properties off State Route 29, to lakeside hospitality properties near the Mercer County Fairgrounds and the Bryson neighborhood.

We also serve property owners across the surrounding region — including Coldwater, St. Marys, Wapakoneta, Minster, Fort Recovery, Rockford, and Van Wert. If you manage a portfolio across western Ohio, we can run a single coordinated testing program across all of it rather than billing you site by site.

Mercer County's commercial inventory is heavy on older block-foundation buildings, manufacturing space, agricultural support facilities, and multi-tenant retail — exactly the kind of building stock where radon problems hide. Our team knows what to look for and where mitigation suction points actually work, not just where they would be convenient to install.

Pricing scales with building size and device count, not guesswork. Typical Celina commercial projects fall in these ranges:

• Small commercial (under 5,000 sq ft): $450–$850 for a full ANSI/AARST-compliant test with sealed report.
• Mid-size commercial (5,000–25,000 sq ft): $850–$2,800 depending on zone count.
• Multifamily per-unit testing: $75–$125 per ground-contact unit with volume scheduling.
• School district programs: Custom quoted by classroom count, generally $40–$70 per tested room.

Commercial mitigation in Celina typically runs $2,500–$8,500 for a single-suction-point system on a small commercial building, scaling up for multi-fan systems on larger footprints. Every quote is written, fixed-price, and includes post-mitigation verification testing. Financing is available for qualifying commercial projects.
