Commercial Radon Services New Madison OH | RC202 Licensed

Radon Eliminator provides Commercial Radon Services in New Madison OH under Ohio Department of Health Mitigation License RC202 — the same credential required to legally install mitigation systems in schools, apartment buildings, office complexes, and multi-tenant facilities across Ohio. We are not an HVAC contractor that also does radon on the side. Radon is what we do, every day, on properties from single-family closings in New Madison to 200-unit apartment portfolios across western Ohio.

Darke County sits in EPA Radon Zone 1 — the highest risk zone in the United States, with predicted average indoor levels above 4.0 pCi/L. That means almost every commercial property in the New Madison area, from buildings near downtown to facilities along US-127 and SR-722, has a measurable probability of elevated radon. For commercial owners, that's not just a health question — it's a liability, tenant retention, and disclosure question.

We handle the entire scope: multi-point diagnostic testing, engineered sub-slab depressurization design, code-compliant installation, post-mitigation verification, and the documentation packet your attorney, lender, or buyer's agent will ask for. When a closing is on the line or a compliance deadline is approaching, we move on your timeline.

Most radon problems in commercial buildings don't get solved on the first attempt because the contractor wasn't a radon specialist — they were a basement waterproofer or a general remodeler who watched a YouTube video. Commercial structures are different. Slab geometry, expansion joints, elevator pits, parking decks, HVAC interactions, and tenant occupancy schedules all change the mitigation strategy.

• RC202 Ohio License — published, verifiable, and required for legal work on schools and multi-family in Ohio.
• EPA-aligned protocols — we follow ANSI/AARST MAMF-2017 (multifamily) and MA-MF (commercial) standards, not residential shortcuts.
• Closing-deadline guarantee — we will tell you upfront whether we can meet your closing date, and we don't blow up real estate transactions.
• Transparent commercial pricing — written quotes with line-item scope, not vague "call for a price" runarounds.
• Multi-vertical experience — schools, apartments, office, retail, light industrial, healthcare, and assisted living across Ohio.
• Documentation packet — post-mitigation test results, manometer readings, system diagrams, and warranty paperwork delivered as a single PDF for your file.

For real estate professionals in New Madison, Greenville, Versailles, and Arcanum, we maintain a home inspector referral program with a named Special Offer. If you're the inspector, agent, or attorney on the deal, ask about it when you call.

Every commercial property is different. A 1960s school in Darke County has different sub-slab conditions than a 2015 apartment complex or a strip retail center on Main Street. Our scope is built around what your building actually is.

Multi-device placement following ANSI/AARST MA-MF protocols. We use continuous radon monitors (CRMs) for transactional speed — results in 48 hours, not the 90+ days an alpha-track device would take. For larger buildings we follow the EPA's recommendation of one test per 2,000 sq ft of ground-contact floor area. Every test comes with a chain-of-custody report acceptable to lenders, buyers, and regulatory bodies.

The gold standard. We core through the slab at engineered locations, install Schedule 40 PVC riser piping, and route to a roof-mounted radon fan sized to the building's footprint and soil permeability. Systems include manometers, labeling, electrical disconnects, and condensate management — all to current Ohio code.

Multifamily work in Ohio is its own discipline. We design systems that handle stack effect across multiple floors, isolate units to prevent cross-contamination, and accommodate occupied-unit work with minimal disruption. We coordinate with property managers on tenant notice, work hours, and common-area access.

Ohio schools follow ANSI/AARST CC-1000 for testing and SGM-SF for mitigation. We are credentialed for this work and have completed projects in K-12 facilities, daycare centers, and municipal buildings. Work is scheduled around academic calendars when possible.

The package most New Madison buyers and sellers need. We deploy the test, install the mitigation system if levels exceed 4.0 pCi/L, and run the post-mitigation verification — typically within 7 to 10 business days start to finish when the closing clock is ticking.

Here's exactly what happens when you hire Radon Eliminator for commercial radon services in New Madison.

Step 1: Property Intake (Same Day)

We collect the basics by phone or form: building type, square footage, slab construction, occupancy, and your deadline. For transactional work, we ask for the closing date first.

Step 2: On-Site Diagnostic & Quote (24-72 Hours)

A licensed technician walks the property, identifies sub-slab access points, evaluates HVAC interactions, and produces a written, fixed-price quote with system design notes.

Step 3: Continuous Monitor Testing (48 Hours)

If testing hasn't been done, we deploy EPA-protocol CRMs in tamper-evident positions. Results are emailed within hours of pickup.

Step 4: Mitigation Installation (1-3 Days Typical)

Sub-slab depressurization system installed to ANSI/AARST standards. Most commercial systems install in one to three working days depending on building complexity.

Step 5: Post-Mitigation Verification & Documentation

We retest after a 24-hour activation period, deliver the documentation packet, and register the warranty. Your file is closing-ready.

New Madison sits in the western edge of Darke County, where glacial till geology and limestone bedrock create one of Ohio's highest radon-emission zones. The Ohio Department of Health maps Darke County as a Zone 1 high-risk county — predicted average indoor radon above 4.0 pCi/L. We have tested and mitigated properties from the historic district near State Route 722 to commercial parcels along the US-127 corridor, agricultural facilities outside town, and multi-family properties serving workers commuting to Greenville, Eaton, and Richmond, IN.

For real estate professionals working New Madison, Hollansburg, Ithaca, and Castine, radon almost always shows up in inspection reports. The question isn't whether you'll encounter it — it's whether your radon contractor can move fast enough to keep the deal alive. We work with title companies and attorneys throughout Darke, Preble, and Miami Counties and understand the regional closing customs.

Beyond New Madison, we serve commercial clients across Ohio including Columbus, Cleveland, Canton, Akron, Arlington, and Richmond-area properties. That statewide footprint matters — it means our process, pricing, and documentation are consistent whether you own one building in New Madison or a portfolio across the state.

We publish pricing ranges because "call for a quote" wastes everyone's time. Final pricing depends on building size, slab configuration, and required fan capacity, but here's the honest range for the New Madison market:

• Commercial radon testing (up to 10,000 sq ft): $450 - $1,200
• Small commercial mitigation (single retail/office, < 5,000 sq ft): $2,800 - $4,500
• Apartment building mitigation (per building, design-dependent): $4,500 - $18,000+
• School / large institutional: custom engineered quote
• Real estate transaction package (test + mitigation + re-test, residential or small commercial): starting at $1,495

Financing is available for qualifying commercial projects. All systems include a workmanship warranty and a guaranteed post-mitigation result below 4.0 pCi/L — or we keep working until we hit it.
