Radon Eliminator provides Radon Mitigation New California OH property owners can rely on — installed by Ohio-licensed professionals operating under Ohio Radon Mitigation License RC202. We don't sell fans. We install permanent, code-compliant active soil depressurization systems engineered to reduce indoor radon below the EPA action level of 4.0 pCi/L, and we document the result with a post-mitigation test you can hand to your buyer, your inspector, or your county.

New California sits in Union County, inside one of Ohio's elevated-radon corridors. The Ohio Department of Health and the EPA classify most of central Ohio — including Union, Delaware, and Franklin counties — as Zone 1, meaning average indoor radon screening levels exceed 4.0 pCi/L. That's not marketing language. That's geology. The glacial till and limestone bedrock under New California, Plain City, Dublin, and Marysville naturally release radon gas, which then accumulates in basements, crawl spaces, and slab-on-grade foundations.

If your home inspection just flagged a number above 4.0, you have a closing date breathing down your neck, or you simply read the Ohio radon map and got concerned — you're in the right place. We handle residential mitigation, commercial buildings, schools, and apartment complexes throughout New California and the surrounding 43064 service area.

Most local radon companies bury their license number, dodge straight pricing, and treat real-estate deadlines as an inconvenience. We do the opposite. Here's what separates us as the best Radon Mitigation New California provider for serious property owners:

• Ohio Mitigation License RC202 — stated upfront on every quote, every invoice, every permit. Ask any contractor for theirs before you sign.
• EPA-aligned protocols — we follow ANSI/AARST standards for measurement (MAH-2019) and mitigation (SGM-SF-2017, RMS-MF-2018, RMS-LB-2018), the same standards Ohio law references.
• Closing-Date Radon Service — when a real-estate contract is on the line, we schedule around your closing, not our calendar. Most residential mitigation jobs in New California are completed in one day with a 48-hour post-test.
• Multi-vertical experience — we mitigate single-family homes, commercial buildings, Ohio schools, and multi-unit apartment complexes. Larger properties require sub-slab diagnostics and engineered designs most local shops aren't equipped to deliver.
• Clear, written pricing — no vague phone quotes. You get a fixed price, scope of work, fan model, warranty terms, and expected post-mitigation pCi/L range in writing.
• Home-inspector partner program — published referral pricing for inspectors who refer mitigation work, with documented turnaround commitments.

That combination — licensed, fast, multi-vertical, and transparently priced — is why agents, inspectors, and property managers across central Ohio call us first.

We deliver the full range of Radon Mitigation services New California OH properties require — from initial EPA-aligned measurement through permanent system installation and post-mitigation verification.

The standard New California mitigation system is active sub-slab depressurization (ASD). We core a suction point through your basement slab or crawl-space membrane, route a 3- or 4-inch Schedule 40 PVC pipe to the exterior or up through the structure, and install a continuously-running radon fan (RadonAway GP, HP, or XP series, sized to your foundation) that vents above the roofline per code. A manometer is mounted on the riser so you can verify the system is working at a glance. Typical residential price range in the New California / Marysville / Dublin corridor: $1,295 – $2,150 depending on foundation type, suction points required, and routing.

Buildings over 2,000 sq ft of foundation footprint require multi-point diagnostics, communication testing between suction points, and often multiple fans on a manifold. We handle Ohio Department of Health-compliant mitigation for apartment complexes, condo associations, daycare centers, and K-12 schools. These projects include sealed sumps, vapor barriers on crawl spaces, HVAC interaction analysis, and continuous radon monitor (CRM) verification testing per ANSI/AARST RMS-MF and MAMF protocols.

We provide short-term (48-hour) continuous radon monitor testing for real-estate transactions and long-term alpha-track testing for baseline assessment. Real-estate test results are delivered same-day after pickup, signed, with chain-of-custody documentation acceptable to lenders and title companies. This is the fastest path for a New California buyer or seller who needs a defensible number before closing.

Every system we install includes a post-mitigation radon test 24–48 hours after activation. You receive a signed report showing pre-mitigation and post-mitigation pCi/L values. If the result isn't below 4.0, we return and rebalance the system at no charge — that's our written guarantee.

If you bought a home in New California with an existing mitigation system and the post-test came back high — or the fan is loud, leaking, or 15 years old — we diagnose what's failing. Common issues: undersized fans, missing manometer, unsealed sump lids, improper vent termination, and degraded couplings. We provide a written assessment and a fixed-price upgrade quote.

Our process is built around two priorities: getting the number below 4.0 pCi/L, and documenting it in a way that holds up in a real-estate transaction or a school district audit.

1. Diagnostic site visit. We evaluate your foundation type (basement, crawl, slab, or mixed), locate the optimal suction point using sub-slab communication testing where needed, and identify the cleanest exterior or interior vent route. For multi-family and commercial properties, this step includes HVAC pressure-balance analysis.
2. Written proposal and scheduling. You receive a fixed-price proposal listing fan model, pipe routing, electrical work, warranty, and expected post-mitigation range. For closing-date jobs, we lock your install date in writing.
3. Code-compliant installation. Most New California homes are installed in 4–8 hours by a two-person crew. We pull electrical permits where required and follow ANSI/AARST SGM-SF and Ohio Department of Health installation standards.
4. Post-mitigation testing. A continuous radon monitor is deployed for 48 hours. Results are emailed as a signed PDF suitable for buyers, lenders, and inspectors.
5. System documentation and warranty. You receive a system label, manometer reading baseline, fan warranty (5 years on most RadonAway models), and our workmanship guarantee that radon stays below 4.0 pCi/L.

New California is an unincorporated community in Jerome Township, Union County, along US-42 between Plain City and Dublin. The housing stock is a mix of older farmhouses, 1990s–2000s subdivisions in the Jerome Village and Glacier Ridge corridors, and newer construction toward Mitchell-Dewitt Road and Industrial Parkway. Each of these has a different radon profile.

Older basement homes near US-42 and Hyland-Croy Road frequently test in the 6–12 pCi/L range due to fieldstone foundations and unsealed sumps. Newer subdivisions built on slab or shallow basements still test high because the underlying limestone-glacial-till geology is the same — modern construction simply spreads the radon entry across a larger footprint. Crawl-space homes near the Big Darby Creek watershed often need full vapor-barrier systems rather than slab depressurization.

We regularly service New California, Plain City (43064), Dublin (43016/43017), Marysville (43040), Jerome Village, Powell, and the broader Union and Delaware County markets. If you're searching for Radon Mitigation near me or top Radon Mitigation New California, you're inside our primary service zone with same-week scheduling typical and 48-hour emergency dispatch for closing-date jobs.

For context: Ohio has one of the highest residential radon exposure averages in the United States. The Ohio Department of Health estimates roughly 1 in 3 Ohio homes tests above 4.0 pCi/L. The EPA links long-term radon exposure to approximately 21,000 lung cancer deaths annually — the second-leading cause after smoking. This is not hype. It is the reason mitigation is worth doing correctly, once.

We've structured our pricing to be the affordable Radon Mitigation New California option without cutting corners on fan quality, pipe spec, or post-testing. Standard residential systems in New California range from $1,295 to $2,150. Crawl-space encapsulation systems run $2,200–$3,800 depending on square footage. Commercial and multi-family quotes are scoped after a site visit. Financing is available through Hearth on approved credit, and we accept all major cards.
