If your inspection report came back at 4.2 pCi/L, 8.0 pCi/L, or higher, you are not overreacting. The EPA action level is 4.0 pCi/L, and Delaware County — where Ashley sits — falls inside Ohio's Zone 1 designation, meaning average indoor radon screening levels exceed that threshold. Radon is the second-leading cause of lung cancer in the United States after smoking, and most homes in central Ohio have never been tested.

Radon Mitigation in Ashley, OH is what we do every day. Radon Eliminator is a licensed Ohio radon mitigation contractor (Ohio Mitigation License RC202) operating under EPA-aligned protocols. We install active soil depressurization systems that pull radon out from under your slab and vent it safely above the roofline — permanently, with documentation that satisfies buyers, lenders, school boards, and property managers.

We do not sell fans. We sell a complete, code-compliant system, a clean install, and a post-mitigation number under 4.0 pCi/L — in writing. Call (800) 555-1234 for a same-week assessment in Ashley and the surrounding Delaware County corridor.

Ashley homeowners and agents along US-23, SR-229, and the Olentangy corridor call us because we lead with three things most competitors hide: our license, our timeline, and our price.

• Ohio License RC202 — stated upfront. Ohio requires every radon mitigation contractor to hold a state-issued license. Ask any company for theirs. Most won't say. Ours is RC202, and it appears on every quote and every contract.
• Closing-Date Radon Service. Real-estate deadlines drive our scheduling, not the other way around. If your closing is in 10 days, we work backward from that date — testing, install, and post-mitigation verification sequenced to clear the contingency.
• Clear, written pricing. Most Ashley homes fall between $1,200 and $1,800 for a standard sub-slab depressurization system. Crawlspaces, multi-sump configurations, and finished basements price higher, and we tell you why in writing before any work starts.
• Multi-vertical depth. We mitigate single-family homes, apartment complexes, schools, churches, and commercial buildings. If you manage a multifamily property in Delaware County, you have a specific Ohio contractor for this — us.
• Documented results under 4.0 pCi/L. Every mitigation includes a post-install radon test. If the number is not under the EPA action level, we fix the system at no additional charge.

That is what professional Radon Mitigation Ashley OH service is supposed to look like, and it's why home inspectors across central Ohio refer their clients to us.

The most common job in Ashley. We install an active sub-slab depressurization (ASD) system: a sealed suction pit beneath your basement slab, schedule-40 PVC piping routed through a non-living space, an inline radon fan rated for Ohio soil conditions, a U-tube manometer for system monitoring, and a roofline discharge that meets ANSI/AARST standards. Most installs are completed in 4–8 hours.

Many older Ashley homes — especially properties off Main Street and along the rural stretches of SR-229 — have crawlspaces or mixed foundations. We install sub-membrane depressurization (SMD) systems using reinforced 12-mil vapor barrier, sealed seams, and dedicated suction points. Hybrid foundations get a combined ASD/SMD approach.

Ohio Department of Health protocols for multifamily and large-building radon testing are different from single-family. We design multi-point mitigation systems for apartment complexes, school buildings, daycare facilities, and commercial properties across Delaware and Morrow counties. Property owners get sealed reports suitable for board review and regulatory compliance.

EPA-aligned short-term (48-hour) and long-term radon testing using continuous radon monitors (CRMs) — not mail-in kits. CRM results are timestamped, tamper-resistant, and accepted by every lender and title company in Ohio. Standard turnaround is 48–72 hours from device pickup to written report.

Bought a house with a radon system already installed? We diagnose underperforming systems, replace failed fans, reroute non-compliant piping, and bring legacy installs up to current ANSI/AARST code. If the original installer is gone or the manometer reads zero, call us.

Every mitigation in Ashley follows the same five-step protocol. No improvisation, no surprises.

1. On-site diagnostic visit. We inspect the foundation, identify slab penetrations, locate the best suction point, and walk the proposed pipe route with you. You get a written quote that day or the next morning.
2. Permit and scheduling. For real-estate jobs we coordinate directly with your agent, inspector, or title company. Installs are typically scheduled within 5–10 business days; rush service is available for closing deadlines.
3. System installation. A licensed technician installs the suction pit, pipe network, fan, manometer, and roof penetration in a single visit. Workspace is left cleaner than we found it.
4. Post-mitigation testing. A 48-hour CRM test verifies the system has reduced indoor radon below 4.0 pCi/L. You get the sealed report.
5. Warranty and monitoring. Systems carry a transferable workmanship warranty, and fans are warrantied for 5 years. We recommend a follow-up test every 2 years per EPA guidance.

Ashley sits at the northern edge of Delaware County, with most of the village and surrounding township built on glacial till over fractured limestone bedrock — a textbook setup for radon entry. The EPA classifies Delaware County as Zone 1 (highest potential), with predicted average indoor screening levels above 4.0 pCi/L.

We mitigate homes throughout the 43003 ZIP code and the broader corridor: properties off North Main Street, homes near Ashley Park, rural acreage along Hoover Road and Cole Road, and newer construction off SR-229 toward Marengo. We also serve nearby Sunbury, Galena, Centerburg, Mount Gilead, Delaware, and the unincorporated Oxford Township areas.

Local conditions that drive radon into Ashley homes:

• Older homes with fieldstone or block foundations and unsealed sump pits
• Newer subdivisions with poured slabs over compacted gravel — efficient radon pathways if not vented
• Walkout basements common to the rolling terrain northeast of the village, which can pull radon laterally through exposed soil walls
• Well-water systems that can contribute waterborne radon in rural Delaware and Morrow county properties

This is why affordable Radon Mitigation Ashley work has to be designed for the specific foundation in front of it — not pulled from a catalog. When homeowners search Radon Mitigation near me or top Radon Mitigation Ashley, they need someone who has actually been in Delaware County basements. We have.

We publish ranges because Ashley homeowners deserve a straight answer before they pick up the phone.
