If a home inspection in Somerville just came back at 4.2, 5.8, or 12 pCi/L, you have two problems on the clock: a health concern and a closing date. Radon Eliminator solves both. We are Ohio's RC202-licensed radon mitigation contractor, and we install permanent, code-compliant sub-slab depressurization systems fast enough to keep your purchase agreement on track. No fan-swap shortcuts. No vague timelines. No surprise invoices at the end.

Somerville sits in Preble County, an area the Ohio Department of Health flags as Zone 1 — the highest radon potential in the state. Predicted average indoor radon here runs above 4.0 pCi/L, which is the EPA's action threshold. That means a high test result in Somerville isn't a fluke; it's the geology. The good news: a properly engineered mitigation system reduces indoor radon by 50% to 99%, typically pulling levels well below 2.0 pCi/L.

We serve homeowners, buyers, sellers, REALTORS®, home inspectors, school districts, apartment owners, and commercial property managers across Somerville, Eaton, Camden, West Alexandria, College Corner, and the rest of Preble County. Call (330) 555-RADON to schedule testing or a mitigation quote today.

Most contractors who show up in a search for Radon Mitigation Somerville OH are HVAC generalists with a radon side-hustle. We are not. Radon is the entire business, and we hold the credentials Ohio law requires for the work to even be legal.

• Ohio Mitigation License RC202 — every system we install is signed off by a state-licensed radon mitigation specialist, not a subcontractor.
• EPA-aligned testing protocols — short-term and long-term devices placed per ANSI-AARST MAH-2019 / MAMF-2017 standards, the same standards used in real-estate transactions.
• Closing-deadline turnaround — when a Somerville purchase agreement has a 10-day inspection contingency, we install within that window. Period.
• Multi-vertical credibility — we mitigate Ohio schools, apartment complexes, and commercial buildings. If a school district trusts our work for 600 kids, your basement is well within our wheelhouse.
• Transparent flat pricing — most Somerville single-family homes fall between $1,295 and $1,895 for a complete mitigation system. You get the number before we start, not after.
• Permanent systems, guaranteed — every install carries a written radon-reduction guarantee to below 4.0 pCi/L, plus a 5-year workmanship warranty and lifetime fan warranty options.

Competitors bury their license number. We lead with it. RC202. Verify it with the Ohio Department of Health before you hire anyone.

We handle every property type in Somerville. The system design changes; the standard of work does not.

Buyer's agent asking for a radon test before closing? We deploy continuous radon monitors (CRMs) — not charcoal kits — for tamper-evident, hour-by-hour data that holds up in negotiation. Results delivered within 48 hours of pickup, with a signed report formatted for lenders, title companies, and inspection contingencies.

The gold-standard fix for Somerville homes with basements, crawlspaces, or slab-on-grade foundations. We core the slab, seal accessible openings, route 3- or 4-inch PVC to a radon fan mounted exterior or in an unconditioned attic, and vent above the roofline per EPA and ANSI-AARST standards. Discharge points are placed to avoid windows, soffits, and your front elevation — no ugly white pipe greeting buyers at the front door.

Older Somerville farmhouses and rural Preble County homes often have dirt or partial crawlspaces. We install a 12-mil reinforced vapor barrier sealed to footings and piers, then tie the mitigation suction point into the membrane. You get radon reduction plus a drier, healthier crawl.

Ohio schools are required to test, and Preble County landlords carry disclosure obligations on rental units. We design multi-point, multi-fan systems for large slabs, engineered drawings included, with post-mitigation testing across all occupied zones. Insurance certificates and W-9s ready before we mobilize.

Every install includes a 48-hour post-mitigation test using a calibrated CRM, conducted no sooner than 24 hours after fan startup, per EPA protocol. If we don't hit below 4.0 pCi/L, we adjust the system at no charge until we do. That's the guarantee in writing.

We've built this process around real-estate timelines. It works just as well for owner-occupants who simply want the problem fixed.

1. Phone consult & quote (same day). Tell us the test result, foundation type, and address. You get a firm price range over the phone, often in under 10 minutes.
2. On-site diagnostic (24–72 hours). Our RC202-licensed specialist walks the property, identifies the best suction point, plans pipe routing for minimum visual impact, and confirms the fixed price in writing.
3. System installation (one day). The vast majority of Somerville homes are completed in 4 to 8 hours. We protect floors, vacuum the worksite, and walk you through the system before we leave.
4. Post-mitigation test (48 hours). CRM deployed, data analyzed, signed report delivered to you, your agent, and (if requested) the buyer's agent and title company.
5. Closing-ready documentation. System diagram, warranty, post-test report, and Ohio disclosure paperwork — everything underwriters, inspectors, and attorneys ask for.

Somerville is a small village along State Route 122, surrounded by the karst-influenced limestone bedrock and glacial till that drives Preble County's high radon readings. Homes near Seven Mile Creek, properties along Somerville-Jacksonburg Road, and older brick farmhouses on the rural edges all tend to register on the higher end — not because anything is wrong with the houses, but because of what's underneath them.

We routinely mitigate properties in:

• Somerville village core and Main Street historic homes
• Rural Preble County parcels around Camden, Eaton, and West Elkton
• New construction subdivisions toward Oxford and the Butler County line
• Lake Acton-area homes and weekend properties
• Commercial buildings along the US-127 corridor

Because we know Ohio's Zone 1 geology, we don't guess at fan sizing. We spec the right fan (Radonaway RP145, GP501, or HP2200 depending on draw and resistance) the first time. That's why our systems pass the post-test — and why home inspectors across southwest Ohio refer us when their clients need professional Radon Mitigation Somerville OH homeowners can actually rely on.

Home inspectors: ask about our Inspector Referral Program and the Special Offer we extend to your clients. It's the cleanest hand-off in the business.
