Commercial Radon Services Donnelsville OH | RC202 Licensed

Radon Eliminator delivers Commercial Radon Services Donnelsville OH property owners, real estate professionals, and facility managers can stake a closing on. We are a licensed Ohio radon mitigation contractor — Ohio License RC202 — and we specialize in compliance-grade testing and permanent mitigation systems for commercial buildings, apartment complexes, schools, daycares, and multi-tenant properties throughout Clark County.

Donnelsville sits in one of the highest-radon regions in the United States. The EPA classifies Clark County and the surrounding I-70 corridor as Zone 1 — meaning the average indoor radon level exceeds 4.0 pCi/L, the EPA's action threshold. For commercial property owners, that's not just a health issue. It's a legal exposure, a tenant relations issue, and during a real estate transaction, it's the single fastest way to watch a deal fall apart at the closing table.

We exist to solve that. When an inspection report comes back hot at 6.8 pCi/L and you have nine days until closing, you don't need a generalist HVAC company that 'also does radon.' You need a licensed Ohio radon specialist with a service truck that can be in Donnelsville tomorrow. Call (937) 985-7559 for same-week scheduling.

Most radon work in Ohio is done by basement waterproofers, HVAC subcontractors, or out-of-state franchises with rotating crews. Radon Eliminator is different by design — and that difference matters when your tenants, your buyers, or your school board are counting on the numbers being right.

• Ohio License RC202 — We publish our state mitigation license number on every proposal, every system label, and every post-mitigation report. Most competitors won't.
• Closing-deadline scheduling — Our 'we won't blow up your closing' commitment means commercial and residential testing gets prioritized when a transaction date is on the line.
• Commercial-scale capability — We design and install multi-suction-point active soil depressurization (ASD) systems for buildings up to 100,000+ sq ft. Most local radon guys can't engineer at that scale.
• Multi-vertical experience — Apartment complexes, K-12 schools, medical offices, daycares, churches, and Class B office buildings. We know the code requirements for each.
• Transparent, written pricing — No 'call for a quote' games. Commercial bids include scope, fan model, manometer placement, post-mitigation testing, and warranty terms in writing.
• Lifetime-grade workmanship — Our residential systems carry a transferable warranty. Commercial installations include a 5-year system warranty and a 10-year radon reduction guarantee.

We serve Donnelsville as part of our broader Ohio coverage area, with active jobs in Springfield, Tremont City, New Carlisle, Enon, and across Clark, Champaign, and Miami counties.

Our commercial radon services are built around the EPA's Protocols for Radon Measurement in Schools and the ANSI/AARST MAMF-2017 standard for multifamily and commercial buildings. Whatever the property type, the methodology is documented, defensible, and built to survive due diligence.

We deploy continuous radon monitors (CRMs) and charcoal canister arrays across statistically valid sample sets — not single-room tests. For a 24-unit apartment building, that typically means testing every ground-contact unit plus a 10% sample of upper floors. Results are delivered in a sealed PDF report suitable for lenders, underwriters, and Ohio Department of Health review. Standard turnaround is 48 to 96 hours.

ASD is the gold-standard mitigation method for commercial buildings and the only system the EPA endorses for guaranteed long-term reduction. We engineer suction points based on slab size, sub-slab communication testing, and HVAC interaction. Our installs use commercial-grade Radonaway or Festa fans, sealed PVC risers, and U-tube manometers with audible alarms for code compliance.

Ohio landlords have a legal duty of care regarding known radon exposure. We handle whole-complex mitigation for Donnelsville-area apartment owners — including phased installations that don't displace tenants, sub-metered fan systems for individual unit accountability, and post-mitigation re-testing of every mitigated unit.

Ohio doesn't yet mandate school radon testing, but the EPA strongly recommends it and most insurance carriers now require it. We run district-wide testing programs for K-12 buildings and licensed childcare facilities, with documentation formatted for ODE and ODJFS compliance audits.

This is where deals get saved. We provide 48-hour radon testing for commercial real estate due diligence, retest verification when a buyer disputes a seller's numbers, and full mitigation installs completed within 5-7 business days of contract acceptance. Our reports are accepted by every major Ohio commercial lender we've encountered.

Every commercial project follows a documented five-step process. No surprises, no scope creep, no 'we found another issue' invoices halfway through.

1. Site assessment & scoping call — We review building plans, slab construction, HVAC zones, and any prior radon data. For transaction work, we confirm your closing date first.
2. Diagnostic testing — Pre-mitigation CRM deployment and sub-slab communication testing to determine suction point count and fan sizing.
3. Written proposal — Fixed-price scope including system design, fan specs, sealing work, electrical, manometer placement, and post-mitigation testing. Delivered within 48 hours.
4. Installation — Our W-2 (not subcontracted) install crews complete most commercial systems in 1-3 days. We coordinate around tenant schedules and business hours.
5. Post-mitigation verification — A second round of CRM testing confirms the system reduced radon below 4.0 pCi/L. You receive a final report with system warranty documentation and an Ohio RC202 install certificate.

Donnelsville sits on the Mad River watershed in western Clark County, surrounded by glacial till and fractured limestone bedrock — the exact geology that produces elevated indoor radon. Uranium-bearing rock breaks down naturally, releases radon gas, and that gas migrates upward through soil pores until it hits a building slab. Commercial buildings along the National Road (US-40) corridor, properties near the Bethel Township line, and older structures along Bird Road tend to test highest in our experience.

We've worked properties from the Donnelsville core out through New Carlisle, Park Layne, Medway, and into the Wright-Patterson AFB perimeter. The Clark County average indoor radon level is approximately 6.4 pCi/L — over 60% higher than the EPA action level. For comparison, the national average is 1.3 pCi/L. Donnelsville isn't just in Zone 1 — it's near the top of Zone 1.

That geology means commercial buildings here often need multi-point ASD systems, not the single-fan setups that work in lower-risk regions. It also means a system that 'tested fine' two years ago can drift upward after slab settling, HVAC changes, or tenant build-outs. We recommend biannual retesting for any commercial property with prior elevated readings.

We don't hide pricing behind a phone gate. Here's the honest range for commercial work in the Donnelsville area:

• Commercial radon testing — $8 to $25 per device, with most small commercial buildings (under 10,000 sq ft) falling in the $400–$1,200 range for a complete EPA-protocol test.
• Single-family or small office mitigation — $1,495 to $2,495 for a standard ASD system with one suction point.
• Mid-size commercial mitigation (10,000–40,000 sq ft) — typically $4,500 to $12,000 depending on suction point count and slab complexity.
• Apartment complex or school mitigation — quoted by building; expect $1,800 to $3,500 per mitigated zone or per ground-contact unit.
• Post-mitigation testing — included in every commercial install at no additional cost.

Financing is available for projects over $5,000. For real estate transactions, we can bill at closing through your title company on approved deals.
