Radon Mitigation in Hilltop OH is not a job for a general handyman or an HVAC crew moonlighting on weekends. It is a regulated, licensed trade in the State of Ohio — and Radon Eliminator holds Ohio Mitigation License RC202. Every system we install on the west side of Columbus is engineered to bring indoor radon below the EPA action level of 4.0 pCi/L, sealed, vented, and documented with a post-mitigation test you can hand to a buyer, an underwriter, a school board, or a county inspector.

Hilltop sits in Franklin County, an area the Ohio Department of Health has flagged for elevated radon potential. The clay-heavy soils under neighborhoods like Westgate, Highland West, and the older brick homes along West Broad Street create exactly the kind of soil-gas pressure that pushes radon into basements and crawlspaces. If your inspector handed you a report with a number above 4.0 pCi/L, the problem is real, the fix is permanent, and the timeline is shorter than you think.

Call (614) 333-3343 now for same-week diagnostic visits and closing-date-aligned scheduling.

Most Hilltop homeowners calling us are in one of three situations: a real-estate inspection just came back hot, a county or insurance audit flagged an apartment building or school, or a parent finally connected the dots between basement bedrooms and Ohio's radon map. Here is why those callers choose us over the cheapest bid:

• Ohio License RC202, stated upfront. Most competitors bury or omit their license number. We lead with it because Ohio law requires it and because it is the single fastest way to verify a legitimate mitigator.
• Closing-Date Radon Service. When your purchase agreement says 14 days, we work to 14 days. Diagnostic visit, system design, install, and post-mitigation test — sequenced to your closing, not our convenience.
• EPA-aligned protocols. Pre- and post-mitigation testing follows EPA and AARST standards so the result is defensible to lenders, buyers, school boards, and HUD inspectors.
• Multi-vertical depth. We mitigate single-family homes, apartment complexes, commercial buildings, and K–12 schools. Larger Hilltop property owners are not an afterthought — they are a core practice area.
• Clear, written pricing. No vague "depends on the job" runaround. Most residential Hilltop mitigation systems fall in a predictable range, and you will know the number before we lift a tool.
• Home-inspector partner program. Local Hilltop and Columbus-area inspectors refer to us because our installs do not embarrass them at the re-inspection.

Radon Eliminator delivers a full menu of EPA-aligned radon services across Hilltop and the greater Columbus metro. Every service below is performed under our Ohio RC202 license:

Sub-slab depressurization is the workhorse system for Hilltop's mix of mid-century ranches, post-war Cape Cods, and newer infill builds. We core the slab in a low-visibility location, run sealed PVC up through the structure or out the rim joist, and install a properly sized radon fan — usually a Radonaway RP series or comparable — vented above the eave per EPA guidance. Sealed sumps, sealed crawlspace membranes, and finished-basement-friendly routing are standard, not upcharges.

Continuous radon monitors deliver lab-grade 48-hour results — the standard real-estate transactions require. For commercial buildings, schools, and multi-family properties in Hilltop, we deploy device grids per AARST-NRPP MAMF and MALB protocols. Reports are written to satisfy lenders, insurers, ODH, and school boards.

Larger Hilltop properties — apartment complexes along Sullivant Avenue, commercial buildings near West Broad, daycare and school facilities — require multi-point depressurization, engineered fan sizing, and manometer arrays at each suction point. We design, permit, and install these systems with documentation packets ready for property managers and compliance officers.

Every install is followed by a post-mitigation radon test. If the number is not under 4.0 pCi/L, we are not done — and you are not billed for done. This is the documentation buyers, sellers, agents, and underwriters actually need at the closing table.

Bought a Hilltop home with a system already in place? Half of the legacy systems we inspect in Franklin County are missing a U-tube manometer, vented incorrectly, or running an undersized fan. We diagnose, repair, and bring older installs up to current AARST-CCAH standards.

From the first call to the post-mitigation test, here is exactly how a Hilltop mitigation job runs:

1. Phone intake and timeline lock. We ask for your test result, your closing date if applicable, and your property type. You get a quoted range and a scheduled diagnostic within days, not weeks.
2. On-site diagnostic. A licensed mitigator inspects the foundation, sub-slab communication, sump configuration, and HVAC interactions. You receive a written system design with the suction point, vent route, and fan model specified.
3. Installation. Most single-family Hilltop systems install in one day. Crews are uniformed, insured, and clean up before leaving — drop cloths, HEPA vacs, sealed cores.
4. Post-mitigation test. A continuous monitor runs 48 hours. Reports are emailed as PDFs, ready to forward to your agent, buyer, or compliance officer.
5. Documentation and warranty. System warranty, fan manufacturer warranty, and EPA-aligned test report — all in one packet.

Ohio has one of the highest indoor radon exposure profiles in the United States. The Ohio Department of Health classifies Franklin County as Zone 1 — the highest-risk EPA designation — meaning the predicted average indoor radon level exceeds 4.0 pCi/L. Hilltop sits squarely in that zone.

The Hilltop neighborhood, stretching roughly from Sullivant Avenue south to Greenlawn and west toward I-270, was largely built between the 1920s and 1960s. That means a lot of poured-concrete and block-foundation basements with floor cracks, exposed soil in crawlspaces, and original sump pits — every one of them a radon entry point. We have mitigated homes on Wheatland Avenue, near the Hilltop Branch Library, around Westgate Park, and across the brick-street blocks south of West Broad Street.

Newer infill construction along the West Broad corridor is not immune either. Modern poly vapor barriers slow radon but do not eliminate it, and tighter envelopes can actually concentrate radon indoors. Whether your home was built in 1932 or 2022, the only way to know your number is to test, and the only way to fix a high number is a properly engineered mitigation system.

We also serve the surrounding Columbus communities — Westgate, Franklinton, Galloway, Grove City, Upper Arlington, and beyond — with the same RC202-licensed crews.

Most single-family Radon Mitigation Hilltop OH projects fall between $1,150 and $1,950 installed, including the post-mitigation test. Pricing depends on three things: foundation type (slab, basement, crawlspace, or a combination), vent routing (interior chase vs. exterior), and finish requirements (exposed PVC vs. concealed). Apartment, school, and commercial pricing is quoted per scope after a site visit. We give you a real number on the phone or after the diagnostic — not a runaround.
