Commercial Radon Services New Hampshire OH | RC202 Licensed

Radon Eliminator is Ohio's licensed radon authority (Ohio Mitigation License RC202), and we handle the work most local contractors legally and operationally can't: large-footprint commercial radon services in New Hampshire, OH. From multi-unit apartment complexes off State Route 119 to school districts, medical offices, and warehouse facilities throughout Auglaize County, we design and install code-compliant active soil depressurization systems that bring radon below the EPA action level of 4.0 pCi/L — and keep it there.

Ohio sits in EPA Radon Zone 1, the highest-risk classification in the country. Auglaize County and surrounding western Ohio communities routinely produce indoor radon readings well above 4.0 pCi/L, and commercial property owners carry a legal duty to provide safe occupied spaces. Whether you're a property manager facing a tenant complaint, a school administrator scheduling required testing, or a commercial real-estate investor in the middle of due diligence, our team delivers measurable results on a timeline that fits your obligations — not ours.

Most radon companies are HVAC outfits, basement waterproofers, or general contractors who added "radon" to their service list. Radon Eliminator is different — radon is the only thing we do. That focus matters when you're dealing with a 40,000-square-foot building, a slab-on-grade school wing, or a 24-unit apartment complex where every occupied space must test below action level.

• Ohio License RC202 — published, verifiable, and the only credential the State of Ohio recognizes for commercial mitigation design and installation.
• Multi-vertical depth — residential, commercial office buildings, schools, daycare facilities, apartment complexes, and assisted living. We've engineered systems for every building type Ohio code touches.
• EPA-aligned testing protocols — we follow ANSI-AARST MAH-2019 (multifamily) and MALB-2014 (large buildings) standards, not consumer-grade kits.
• Transparent commercial pricing — we publish scope-based estimates after a site walk, not vague "call for quote" black boxes. You'll know the number before you sign.
• Speed that protects deals and deadlines — if your closing, lease commencement, or compliance audit is on the clock, we build the install schedule around your date.
• Lifetime-grade workmanship — sealed penetrations, properly sized fans, exterior discharge per code, and post-mitigation testing included.

That combination is why we're considered the top Commercial Radon Services New Hampshire OH property owners call when the inspection report comes back hot.

We deploy continuous radon monitors and passive devices on a per-square-foot grid that meets ANSI-AARST MALB-2014 — the standard required for commercial and institutional buildings. Initial measurement typically takes 48 to 96 hours under closed-building conditions. You receive a written report with radon levels per room, HVAC notes, and a clear recommendation: pass, retest, or mitigate.

HUD and many lenders now require radon testing in ground-contact units before financing closes. We test per ANSI-AARST MAH-2019 — every ground-floor unit, plus a statistical sample of upper floors — and design building-wide mitigation when results exceed 4.0 pCi/L. Our crews work unit-by-unit with minimal tenant disruption and coordinate with property management on access schedules.

Our engineered active soil depressurization (ASD) systems use commercial-grade radon fans, sealed sub-slab suction points, properly sized PVC piping routed to code-compliant exterior discharge, and U-tube manometers for ongoing verification. For large slabs we use diagnostic pressure-field extension testing to determine suction-point count and placement — no guesswork, no oversized fans wasting energy.

Buying or selling a commercial property in New Hampshire? We turn radon testing around in 48 hours and can have a mitigation system installed and verified within 7 to 10 business days of a hot result. That's the "we won't blow up your closing" promise — and it's why commercial brokers and home inspectors across Ohio refer their clients to us.

Every system we install includes post-mitigation testing to confirm radon levels are below 4.0 pCi/L. For commercial clients, we offer annual re-testing contracts that satisfy due-diligence requirements, lender covenants, and insurance documentation. You get a verifiable paper trail year after year.

Commercial radon work doesn't run like a residential job. Buildings are bigger, stakes are higher, and the documentation matters. Here's how we move a New Hampshire commercial project from first call to verified result:

1. Phone consultation & scope review — We talk through building square footage, foundation type, occupancy, and your deadline. Most calls take 15 minutes and end with a same-week site-visit date.
2. On-site assessment — A licensed RC202 mitigation specialist walks the building, identifies foundation contact areas, HVAC zones, and suction-point candidates, and documents constraints. You receive a written scope and fixed-price proposal within 48 hours.
3. EPA-aligned testing — We deploy continuous radon monitors and passive devices per the applicable ANSI-AARST standard. Testing runs 48–96 hours under controlled conditions, and results are reported room-by-room.
4. Mitigation design & install — If levels exceed 4.0 pCi/L, we engineer the system, pull required permits, and install. Most commercial projects complete in 2–5 working days depending on footprint.
5. Verification testing & handoff — We re-test after the system stabilizes (typically 24–48 hours) and deliver a final report showing pre- and post-mitigation radon levels, system specs, fan warranty, and maintenance schedule.

New Hampshire sits in the western Ohio glacial plain — a region known for clay-heavy soils, shallow water tables, and the kind of sub-slab pressure dynamics that make radon a persistent problem in commercial buildings. We've worked across Auglaize County and the surrounding communities including Wapakoneta, St. Marys, New Bremen, Minster, and Cridersville, and we understand how regional geology drives the design choices that make a mitigation system actually work.

Local commercial properties we've serviced include office buildings near US-33, school facilities throughout the Wapakoneta City and Waynesfield-Goshen districts, and multifamily developments along the SR-67 corridor. Auglaize County's mix of older slab-on-grade construction and newer commercial builds means we see radon entry patterns ranging from foundation cracks to expansion joints to utility chases — and we design for all of them.

If you're a New Hampshire property owner, school administrator, or commercial broker searching for affordable Commercial Radon Services New Hampshire businesses can trust, we're the licensed Ohio specialist already working in your zip code.

We publish honest commercial pricing because vague "call for a quote" tactics waste your time. Final numbers depend on building size, foundation type, and suction-point count, but here are realistic ranges for New Hampshire commercial work:

• Commercial radon testing (under 25,000 sq ft): $400–$1,800 depending on monitor count and reporting requirements
• Large-building testing (25,000+ sq ft, schools, warehouses): custom-scoped, typically $1,500–$6,000
• Multifamily testing programs: per-unit pricing with volume discounts; most 12–24 unit complexes fall between $1,200 and $3,500
• Commercial mitigation system installation: typically $3,500–$15,000+ depending on slab area and suction-point count
• Annual monitoring contracts: from $350/year for standard commercial buildings

Every install includes a Commercial Radon Services warranty on workmanship and a manufacturer warranty on the fan.
