If your inspection report just came back at 4.2, 7.8, or 12 pCi/L, you don't need a sales pitch — you need a licensed Ohio radon professional on site this week. Radon Eliminator is the team Highland homeowners, agents, and property managers call when the number on the report is too high and the closing date is too close. We hold Ohio Radon Mitigation License RC202, we follow EPA-aligned protocols, and every system we install is designed to drive your home below the EPA action level of 4.0 pCi/L — verified by post-mitigation testing, not assumed.

Radon Mitigation Highland OH isn't a side service for us. It's our entire business. Ohio sits in EPA Radon Zone 1 — the highest-risk classification — and Highland County's clay-heavy soils and limestone bedrock create exactly the conditions that drive radon up through foundation slabs and crawlspaces. We've engineered hundreds of sub-slab depressurization systems across central and southern Ohio, and we know what Highland's housing stock — from older farmhouses near Hillsboro to newer builds around Greenfield and Leesburg — actually needs.

Call (800) 277-2366 for same-week service, or request a written quote online. No gatekeeping, no vague pricing, no "we'll call you back."

Most Highland-area radon calls come from one of three scenarios: a real-estate inspection flagged elevated levels, a parent saw the county radon map and got worried about kids sleeping in a basement bedroom, or a commercial property owner just got notified of a compliance issue. We built our company around all three.

• Ohio License RC202, stated upfront. Most competitors bury their license number — or don't have one. Ohio law requires a licensed mitigation contractor to install any radon reduction system. Ask any bidder for their RC number before you sign.
• Closing-Date Radon Service. When your purchase agreement has a radon contingency and 10 days on the clock, we schedule the install around your closing — not the other way around. Testing, install, and post-mitigation verification documented and delivered to your agent or title company.
• Guaranteed under 4.0 pCi/L. Every system is designed, sized, and installed to bring your home below the EPA action level. If post-mitigation testing comes back high, we adjust the system at no additional cost.
• Residential, commercial, schools, and apartments. We're one of the few Ohio firms that handles multi-family buildings, school districts, and commercial buildings with the same in-house licensed team — not subcontractors.
• Clean, code-compliant installs. PVC routed for minimum visual impact, exterior fan placement that meets ANSI/AARST-SGM-SF standards, manometer mounted at eye level, and a system label with our license number affixed to the unit.
• Home Inspector Partner Program. Highland-area inspectors get a published referral structure and priority scheduling — because the inspectors we work with want their clients taken care of, not upsold.

For agents and inspectors: ask us about our real-estate transaction package — 48-hour test results, written mitigation quote within one business day, and install scheduling that aligns with your closing timeline.

We are a full-service radon firm — testing, mitigation, and verification all under one license. Every service below is performed by Ohio-licensed staff, never subcontracted.

Short-term (48-hour) and long-term (90+ day) testing using continuous radon monitors and EPA-aligned protocols. When mitigation is needed, we install active sub-slab depressurization (ASD) systems — the EPA's gold-standard method — with sealed sumps, vapor barriers for crawlspaces, and high-efficiency radon fans rated for Ohio's freeze-thaw climate. Typical residential install: one day, $1,400–$2,200 depending on foundation type and routing complexity.

Highland-area apartment owners, assisted-living facilities, and commercial property managers face specific legal exposure under Ohio Department of Health rules. We design and install multi-point mitigation systems for slab-on-grade commercial buildings, multi-unit residential, and mixed-use properties, with proper riser sizing, building-pressure analysis, and documentation suitable for insurance and ODH compliance files.

Ohio EPA recommends radon testing for all schools every five years. We work with school districts and public-building administrators on full-facility testing protocols (one device per classroom-equivalent area), engineered mitigation for HVAC-coupled buildings, and the kind of public-facing documentation school boards expect.

An install isn't finished until the number is under 4.0 pCi/L. We return 24–48 hours after activation to perform short-term verification testing, document the result, and provide you and your title company (if applicable) with a signed report you can attach to the property file. Every system also includes a U-tube manometer so you can verify proper operation any time.

Inherited a system from a previous owner? Buying a house with an old fan that may or may not be working? We inspect existing radon mitigation systems, test the home, evaluate fan performance and pressure differential, and either certify the system as functional or quote a targeted repair. Common issues: failed fans (8–10 year typical lifespan), cracked PVC, and seals broken by basement remodels.

Every Highland radon mitigation job follows the same documented sequence. No surprises, no scope creep, no "we found something" mid-job.

1. Phone consultation and quote (same day). Tell us your foundation type, current radon reading, and timeline. You'll get a clear price range before we ever drive out — typically $1,400–$2,200 for a single-family home.
2. On-site diagnostic visit. We assess foundation, sump pit, crawlspace conditions, and routing options. We confirm the install date and put it in writing.
3. System installation (one day). Suction point cut and sealed, PVC routed, fan mounted exterior, electrical connected, manometer installed, system labeled with our RC202 license number.
4. 24–48 hour post-mitigation test. Continuous radon monitor placed in the lowest livable area. We deliver the documented result directly to you, your agent, or your title company.
5. Warranty activation. Workmanship and system performance warranty in writing. Fans carry manufacturer warranties of 5 years; our installs carry a transferable system warranty.

Highland County's geology is exactly why radon is a problem here. The county sits on Silurian-age dolomite and limestone bedrock, with widespread clay till soils — both of which produce and trap radon gas. Older homes around Hillsboro, fieldstone-foundation farmhouses near Greenfield, slab-on-grade ranches in Leesburg and Lynchburg, and newer construction around Rocky Fork Lake all show elevated radon at higher rates than the national average. Ohio Department of Health data places Highland County squarely in the elevated-risk category, with many tested homes returning results above the 4.0 pCi/L action level.

We serve all of Highland County and the surrounding region — including Hillsboro, Greenfield, Leesburg, Lynchburg, Mowrystown, Sinking Spring, and the lake communities along Rocky Fork and Paint Creek. Drive times from our service area mean we can typically be on site within 48 hours, and same-day for closing-deadline emergencies.

Whether you're a homeowner near Pleasant Plain who just got an alarming inspection report, a landlord with units in Hillsboro, or a school administrator working through ODH testing recommendations, we're the licensed Ohio team that handles it start to finish.

We publish honest pricing because vague quotes are the #1 complaint we hear about other radon companies. For a typical Highland-area home:

• Standard basement or sump-tied install: $1,400 – $1,800
• Crawlspace with vapor barrier: $1,900 – $2,500
• Slab-on-grade with interior routing: $1,600 – $2,200
• Multi-suction-point or complex foundation: $2,300 – $3,200
• Short-term radon test (real-estate grade): $150 – $200
• Commercial / multi-family: Quoted after site visit

Financing is available, and we accept all major payment methods including transactions handled through title companies at closing. Ask about our affordable Radon Mitigation Highland OH packages for real-estate transactions.
