Commercial Radon Services Sardis OH | Licensed RC202 Pro

Radon Eliminator delivers Commercial Radon Services Sardis OH property owners, real estate agents, and facility managers can stake a closing — or an occupancy inspection — on. We are licensed under Ohio Department of Health Mitigation License RC202, and we specialize in the buildings most local contractors won't touch: multi-family apartment complexes, K-12 schools, daycare facilities, office buildings, medical offices, and commercial real estate in transition.

Sardis sits along the Ohio River in Monroe County, an area the EPA classifies as Zone 1 — predicted average indoor radon screening levels above 4.0 pCi/L. That isn't marketing copy. It's geology. The Appalachian foothills, fractured shale, and limestone bedrock under Monroe, Belmont, and Washington counties release more radon than most of the country. If you own a commercial building in Sardis, the question is not whether you have radon — it's how much, and what you're going to do about it before a tenant, inspector, or buyer asks.

We handle the testing, the engineering, the installation, and the post-mitigation verification. One licensed team. One paper trail. One name on the certification.

Most contractors in southeastern Ohio do radon on the side. We do radon. Period. That distinction matters when you're signing a lease addendum, refinancing a 40-unit apartment building, or responding to a school board's air quality directive.

• Ohio License RC202 — published openly, verifiable through the Ohio Department of Health. Not every Sardis competitor can say that.
• Real-estate transaction speed — when a Sardis closing is 10 days out and the inspector flagged 6.8 pCi/L, we mobilize. Testing, system design, install, and post-mitigation retest scheduled to your closing calendar.
• Commercial-grade equipment — RadonAway GP501 and HP2200 series fans, sealed and labeled per ANSI/AARST CC-1000 standards for large-building mitigation. Not the residential-grade fans some companies upsize and hope for the best.
• Multi-vertical experience — apartment complexes, schools, nursing homes, churches, and office buildings across Ohio. We've done the compliance paperwork. We know what county health departments and EPA Region 5 expect.
• Transparent pricing — written, itemized estimates. No "call for a quote" runaround. You'll know what a commercial mitigation system in Sardis costs before we leave the site walk.

That's why home inspectors, attorneys, and commercial brokers from Sardis to Marietta to Steubenville refer their clients to us instead of rolling the dice on a generalist.

Commercial radon testing is not a glorified home test. For buildings over 2,000 square feet, multi-story structures, and properties with multiple HVAC zones, the EPA and ANSI/AARST require a building-specific test plan: continuous radon monitors placed at a minimum density of one device per 2,000 sq ft of lowest-occupied space, with HVAC operating under normal conditions. We deploy Sun Nuclear and Femto-Tech continuous radon monitors — the same instruments accepted in court and by Ohio EPA reviews — and produce a chain-of-custody report your lender, attorney, or board can defend.

Sub-slab depressurization (SSD) is the gold standard for commercial radon mitigation, and the most common solution we install on Sardis-area commercial buildings. We core through the slab, install sealed PVC suction points, route piping through chases or exterior walls, and discharge above the roofline per ANSI/AARST CCAH-2020. Every system includes a manometer, a system-failure alarm, and a labeled service tag with our RC202 license number.

HUD requires radon testing and mitigation on multi-family properties involved in federally-backed financing. If you own an apartment building in Sardis or anywhere along the Ohio River corridor, we handle the full HUD Multifamily Accelerated Processing (MAP) testing protocol, plus the engineered mitigation plan your lender's reviewer expects. We've worked through FHA 223(f) refinancing timelines and know how to keep the rate lock alive.

Switzerland of Ohio Local School District serves Sardis, and Ohio schools fall under EPA guidance for periodic radon testing. We design test plans that map every ground-contact classroom, gym, and basement office, then engineer mitigation that runs quietly during instructional hours. We've done this work in Ohio public schools, private academies, and licensed daycare centers — all documented, all on letterhead.

For commercial real estate transactions in Sardis, we offer a closing-priority track: 48-hour test deployment, 72-hour reporting, and mitigation installation scheduled within 5–10 business days of contract acceptance. Buyers, sellers, listing agents, and 1031 exchange coordinators all get the same direct line to a licensed mitigator.

Every Sardis commercial project follows the same disciplined sequence. No improvisation, no shortcuts.

1. Site Walk & Diagnostic Survey — We inspect the slab, sumps, foundation joints, HVAC layout, and any existing sub-membrane vapor systems. We perform a sub-slab communication test to confirm how radon will move under your specific foundation.
2. Continuous Monitor Testing — Minimum 48-hour test using EPA-approved CRMs placed per ANSI/AARST density requirements. Closed-building conditions documented.
3. Engineered Mitigation Design — We provide a written design with fan model, pipe routing, suction-point count, projected post-mitigation pCi/L, and itemized cost. Stamped if your jurisdiction requires it.
4. Installation by Licensed Mitigators — Our crews are W-2 employees, RC202-licensed or working under direct license supervision. We pull permits where required, coordinate with your facility manager, and minimize tenant disruption.
5. Post-Mitigation Verification & Documentation — A second CRM test confirms the system pulled levels below 4.0 pCi/L (we target below 2.0). You receive a sealed report, system warranty, and labeled service tag.

Sardis sits in a stretch of the Ohio River Valley where radon is not a hypothetical risk. The Ohio Department of Health's radon database shows Monroe County averaging well above the 4.0 pCi/L EPA action level, with individual readings in nearby Clarington, Beallsville, and Woodsfield commonly testing in the 8–15 pCi/L range. The same Marcellus and Utica shale formations that made this corner of Ohio a natural gas hotspot also release uranium-decay radon into basements, crawl spaces, and slab-on-grade commercial buildings.

We work across Monroe County and the surrounding region — from commercial buildings near the SR-7 corridor and downtown Sardis, to apartment complexes in New Martinsville just across the river, to office and retail properties in Woodsfield, Hannibal, Powhatan Point, and along the route up to St. Clairsville. We also serve clients connected to the Switzerland of Ohio school district, the Ormet industrial corridor legacy properties, and small-business owners along the Ohio River scenic byway.

Local familiarity matters because mitigation design is site-specific. A 1920s brick building in downtown Sardis with a fieldstone foundation needs a different system than a 2015 metal-frame distribution facility with a modern vapor barrier. We've done both. We know which Monroe County buildings have block-wall radon entry problems and which slab-on-grade structures need multi-point suction.

We're one of the few Ohio radon contractors that will give you real numbers up front. General ranges for commercial work in the Sardis market:

• Commercial CRM testing: $295 – $1,200+ depending on building size and device count (typical 10,000 sq ft building: ~$650).
• Small commercial SSD mitigation (single suction point, <5,000 sq ft): $2,200 – $3,800.
• Mid-size commercial mitigation (multi-point, 5,000–25,000 sq ft): $4,500 – $12,000.
• Apartment & school mitigation: quoted by building after diagnostic walk — typically $1,800–$3,500 per zone.
• Post-mitigation verification testing: included in every install.
