Commercial Radon Services Farmington OH | Licensed RC202

Radon Eliminator provides Commercial Radon Services in Farmington OH for property owners, real estate investors, school districts, and apartment operators who carry legal responsibility for indoor air quality. We are a licensed Ohio radon mitigation contractor (Ohio License RC202) — not a basement waterproofer or HVAC company that also dabbles in radon. Every test, diagnostic, and mitigation system we install is performed under that license, documented to EPA protocol, and engineered to bring your building below the 4.0 pCi/L action level.

Farmington sits in Trumbull County, an area the Ohio Department of Health classifies as Zone 1 — the highest radon potential designation. The glacial till and shale-rich bedrock under northeast Ohio routinely produces commercial buildings testing between 6 and 20 pCi/L, and we have measured Trumbull County structures north of 40 pCi/L. For a property owner, that is not a curiosity — it is a documented occupational and tenant-liability exposure. Our job is to fix it permanently, on a schedule that fits your lease, closing, or school-year calendar.

We work across every commercial vertical: office buildings, medical and dental practices, daycare facilities, K-12 and charter schools, nursing homes, warehouses with occupied office areas, retail centers, and multi-family apartment complexes. If your property has occupants, a foundation, and an Ohio address, we can test it, diagnose it, and mitigate it.

Most radon companies serving Farmington are residential-only operators. Commercial work demands a different skill set — larger building footprints, slab-on-grade and mixed foundation diagnostics, multi-zone pressure field extension, ASHRAE-compliant exhaust routing, and documentation a school board or commercial lender will actually accept. Here is what separates us from the local field:

• Ohio License RC202 — published, verifiable, and current. Ohio law requires a licensed mitigation contractor for any commercial radon work. We list our license number on every proposal, invoice, and post-mitigation report.
• Real-estate-transaction speed. We have built our scheduling around the closing calendar. When a commercial inspection flags elevated radon and you have 14 days to close, we can complete a continuous radon monitor test in 48 hours and install a mitigation system within the contingency window. We will not blow up your deal.
• Multi-vertical depth. We are one of the few Ohio firms with active project history in schools, apartments, and commercial real estate — including buildings over 50,000 square feet with multiple sub-slab zones.
• Transparent pricing. No "call for quote" runaround. Our commercial proposals itemize diagnostic work, system components, electrical, and post-mitigation testing in writing.
• EPA-aligned protocol on every job. We follow ANSI/AARST MAH-2019 and CC-1000 standards for multifamily and large building mitigation — the same standards HUD, FHA, and most institutional lenders now require.
• Lifetime-grade workmanship. Radon fans, vent stacks, manometers, and sealing details installed to outlast the building's next ownership cycle.

Farmington property managers and listing agents call us because the deliverable matters. A post-mitigation report with our RC202 license on the letterhead, two independent post-test results below 4.0 pCi/L, and a system diagnostic sheet is what lenders, buyers, and school boards sign off on.

We deliver a complete commercial radon program — not just a fan on the side of a building. Every engagement is scoped to the property's foundation type, occupancy class, and regulatory driver (real estate closing, HUD requirement, school mandate, or tenant complaint).

For commercial buildings, EPA recommends testing every occupied room on the lowest level, with deployment density scaled to building square footage. We use NRPP-certified continuous radon monitors (CRMs) that record hourly pCi/L data, plus device tampering and environmental factors. For real estate transactions we offer 48-hour CRM testing with a same-day signed report. For long-term occupancy assessments, we deploy alpha track detectors for 90-day baselines.

Apartment owners in Farmington and across Trumbull County face increasing scrutiny under HUD radon policy and tenant-rights statutes. We design active sub-slab depressurization systems sized for multi-unit buildings, including riser routing through unoccupied chases, exterior fan placement to control noise, and unit-by-unit post-mitigation testing.

Ohio school districts increasingly test under the EPA's Radon Measurement in Schools protocol. We perform classroom-by-classroom CRM testing, design mitigation systems that integrate with existing HVAC, and provide the documentation administrators need for board presentations and parent communications.

This is our highest-velocity service line. When a commercial inspection report flags radon mid-deal, we mobilize within 72 hours, complete diagnostic work, install the mitigation system, and run post-mitigation verification — all inside a typical commercial due-diligence window. Buyers, sellers, and brokers get a single point of contact and a hard finish date in writing.

Every system we install includes 48-hour post-mitigation CRM testing to confirm levels below 4.0 pCi/L. For commercial clients we also offer annual re-test programs to satisfy lender, insurance, and HUD reporting requirements.

Every commercial project follows the same disciplined sequence — the only thing that changes is scale.

Step 1: Site Walk and Foundation Diagnostic

We map the foundation: slab-on-grade vs. basement vs. crawlspace, slab joints, sumps, plumbing penetrations, and HVAC return paths. For larger Farmington commercial buildings, this often takes a half day and produces the design basis for system zoning.

Step 2: Pressure Field Extension Testing

We drill diagnostic test points and measure sub-slab communication using a micromanometer and smoke. This determines how many suction points your building needs — the single biggest cost driver on a commercial job, and the variable most unlicensed contractors guess at.

Step 3: Engineered System Design and Written Proposal

You receive a written design with suction point locations, pipe routing, fan model and CFM specs, electrical work, exterior discharge location, and total fixed price. No surprise change orders.

Step 4: Installation by Licensed Crew

Installation is performed by Ohio-licensed personnel working under RC202. Most commercial systems install in 2 to 5 working days. We coordinate with property managers to minimize tenant disruption.

Step 5: Commissioning and Post-Mitigation Testing

We commission the system, verify manometer readings, label every component, and deploy post-mitigation CRMs for 48 hours. You receive a final report with two independent test results, system specifications, warranty documentation, and our RC202 license — the package a lender, buyer, or school board actually wants to see.

Farmington Township sits in the rural southeast corner of Trumbull County, with a mix of older farmhouse-era commercial structures along State Route 88 and newer slab-on-grade buildings near the West Farmington village core. Each foundation type behaves differently under depressurization, and Farmington's regional geology — Berea sandstone overlaid by glacial till — produces strong sub-slab communication when systems are designed correctly.

We routinely work commercial properties across the surrounding corridor: Warren, Champion Heights, Cortland, Newton Falls, Bristolville, Mesopotamia, and out toward Middlefield. Properties along the SR-534 and SR-87 corridors, the commercial strips near Mosquito Lake State Park, and the agricultural-commercial blend through Farmington Center all present the same regional radon profile — high source-term uranium in the underlying shale and bedrock fractures that channel radon upward into building envelopes.

Farmington commercial property owners we have served include small office buildings, agricultural processing facilities, a handful of churches and community buildings, and multi-unit residential properties tied to local landlords. We know the building stock, we know the closing attorneys and inspectors who operate in this market, and we know how to deliver documentation that satisfies a Trumbull County commercial transaction.

Commercial radon mitigation pricing in Farmington is driven by three factors: building square footage, number of required suction points, and exterior vs. interior routing complexity.

• Small commercial (under 5,000 sq ft, single suction point): typically $1,800 – $3,200 installed.
• Mid-size commercial / small multi-family (5,000 – 15,000 sq ft): typically $3,500 – $9,500 depending on zone count.
• Large commercial, schools, large apartment buildings: engineered per project; we provide fixed-price written proposals after diagnostic.
• Commercial radon testing (CRM, 48-hour): starts at $195 for the first device with volume pricing per additional location.

We do not quote final pricing over the phone without a site visit — anyone who does is either lowballing to win the call or planning a change order. We do publish the ranges above so you can budget honestly.
