Commercial Radon Services New Bloomington OH | RC202 Licensed

Ohio has some of the highest radon levels in the United States, and Marion County sits squarely inside EPA Radon Zone 1 — the highest-risk designation. For owners of commercial property, apartment buildings, schools, and office complexes in New Bloomington, that's not an abstract statistic. It's a legal, financial, and life-safety problem you're responsible for.

Radon Eliminator delivers Commercial Radon Services in New Bloomington OH built around three non-negotiables: licensed Ohio expertise (Ohio Department of Health Mitigation License RC202), EPA-aligned testing protocols, and installation timelines that respect closing dates, board meetings, and tenant move-ins. We don't moonlight as an HVAC or basement waterproofing company that also "does radon." Radon is what we do, and Ohio is where we do it.

Whether you manage a multi-tenant office on State Route 309, own an apartment building near downtown New Bloomington, or sit on a school board responsible for student safety, our team builds permanent, code-compliant mitigation systems that bring radon levels below the EPA action threshold of 4.0 pCi/L — typically well under 2.0 pCi/L after install.

Commercial radon work is not residential radon work scaled up. It involves larger building footprints, slab complexity, mechanical interaction with HVAC, occupant communication, and — for schools and rentals — statutory disclosure and compliance obligations. Most local radon contractors in central Ohio aren't equipped for that. Here's what separates us:

• Ohio License RC202 — published, verifiable, and held by the technicians actually on your jobsite. Not subcontracted out.
• Multi-vertical commercial depth — we work on apartment complexes, schools, daycares, medical offices, manufacturing facilities, and mixed-use buildings across Ohio. We know how each one is regulated differently.
• Real-estate transaction speed — when a commercial purchase or lease hinges on a clean radon report, we test and (if needed) mitigate inside the inspection contingency window. We don't blow up closings.
• Transparent, written pricing — no "call for a quote" runaround. Commercial scopes get itemized estimates with system specs, manometer placement, fan model, and post-mitigation testing included.
• Permanent systems, not patch jobs — sub-slab depressurization, sub-membrane systems for crawlspaces, and block-wall depressurization where required by building construction. Engineered to last.

We're the radon company that other Ohio inspectors, agents, and property managers refer when the stakes are high.

For buildings larger than a single-family home, the EPA and ANSI/AARST protocols require a specific number and placement of test devices based on square footage, foundation type, and occupancy. We deploy continuous radon monitors and/or charcoal canisters across every required zone — lowest occupied level, separate HVAC zones, and isolated foundation sections.

Standard commercial test turnaround is 48 to 96 hours on-site, with a signed, sealed report delivered within 24 hours of pickup. Rush real-estate transaction testing is available.

Ohio landlords and HOAs face increasing disclosure pressure and, in some jurisdictions, mandatory testing on rental transfers. We design building-wide mitigation strategies that handle shared slabs, multiple foundation types within one structure, and tenant-occupied unit access logistics. Our systems are quiet (fan dB-rated for residential proximity), routed to minimize tenant disruption, and monitored with U-tube manometers at every active point.

Ohio schools and licensed daycares operate under heightened public-trust standards. We perform full-building radon assessments using long-term monitoring protocols, coordinate with school operations to test during occupied hours (per EPA guidance), and design mitigation that integrates with existing HVAC without compromising IAQ or energy performance. Documentation is delivered in a format suitable for board presentation and parent communication.

Closing on a commercial property in New Bloomington and the Phase I or inspection flagged radon? This is our specialty. We deliver pre-purchase testing in 48 hours, mitigation design within 72 hours of test results, and installation typically inside 5–10 business days — fast enough for nearly every commercial closing timeline. Post-mitigation testing confirms levels below 4.0 pCi/L before you sign.

Every commercial mitigation system we install is engineered for the specific building: active sub-slab depressurization (ASD) for slab-on-grade and basement structures, sub-membrane depressurization (SMD) for crawlspaces, and block-wall depressurization for hollow masonry foundations. Systems include a permanent U-tube manometer, labeled electrical disconnect, sealed slab penetrations, exterior fan placement per ANSI/AARST CC-1000, and a discharge point above the roofline away from intake vents.

Commercial radon work demands a disciplined process. Here's how we run every project in New Bloomington:

1. Site Assessment & Scope Call — We review building plans, foundation type, square footage, occupancy, and timeline. For real-estate transactions, we ask about your closing date first.
2. Written Estimate — You receive a line-item proposal: test placement, device count, mitigation system design (if pre-purchased), fan specifications, and total cost. No verbal-only quotes.
3. EPA-Aligned Testing — Devices deployed per ANSI/AARST protocol. Building conditions documented. Test runs 48–96 hours under closed-building conditions where required.
4. Report & Mitigation Design — Signed report with pCi/L results by zone. If mitigation is needed, we deliver an engineered design with drawings.
5. Installation — Licensed Ohio mitigation crew (RC202) installs the system. Typical commercial install: 1–3 days depending on building size and complexity.
6. Post-Mitigation Verification Test — Independent confirmation that radon levels are below 4.0 pCi/L. Final compliance documentation delivered.

New Bloomington sits in northwestern Marion County, near the intersection of State Route 4 and State Route 309, with a building stock that includes historic late-19th-century structures along the village core, mid-century commercial buildings, agricultural outbuildings converted to commercial use, and newer apartment construction along the Marion–Bucyrus corridor. Each of these construction types behaves differently when it comes to radon entry.

The underlying geology — limestone and dolomite bedrock with overlying glacial till — is exactly the kind of substrate that produces elevated radon readings throughout Marion, Wyandot, and Crawford counties. The Ohio Department of Health's county-by-county radon data consistently shows Marion County averaging well above the 4.0 pCi/L action level in tested homes and commercial buildings.

We serve property owners and managers throughout New Bloomington, Waldo, LaRue, Caledonia, Marion, Prospect, Marengo, and the broader Marion County area. Our crews are also active across central Ohio in Columbus, Delaware, Bucyrus, and the surrounding region — so we keep crews and equipment local enough to respond inside a real-estate inspection window.

If your commercial property is north of US-23, south of Wyandot County, or anywhere in the Marion school district footprint, we can be on-site for a commercial assessment this week.

We publish ballpark numbers because "call for a price" wastes everyone's time. Final pricing depends on building size, foundation type, and system complexity, but here's a reasonable expectation for the New Bloomington market:

• Commercial radon testing — $300 to $1,200 depending on building square footage and number of required devices (per ANSI/AARST).
• Small commercial mitigation (under 5,000 sq ft, single foundation) — typically $2,200 to $4,500.
• Mid-size commercial / multifamily mitigation — typically $4,500 to $12,000+ depending on suction points, foundation complexity, and electrical work.
• School & large institutional mitigation — quoted per building after on-site assessment.
• Post-mitigation verification testing — included with every install.

Financing is available on qualifying commercial projects, and we honor a workmanship warranty on every mitigation system we install in Ohio.
