Radon Mitigation Dayton OH | Licensed RC202 Pros

Montgomery County sits in EPA Radon Zone 1 — the highest risk tier in the country. Roughly 1 in 3 Dayton-area homes tests above the EPA action level of 4.0 pCi/L, and we've seen Oakwood, Kettering, and Centerville basements come back at 8, 12, even 20 pCi/L. That's not a scare statistic. It's just Ohio geology: glacial till, fractured limestone, and tight modern foundations that trap soil gas indoors.

Radon Eliminator is Ohio's licensed (RC202) radon authority, and Radon Mitigation Dayton OH is what we do every day. We install permanent sub-slab depressurization systems built to ANSI/AARST standards, not the cheap fan-swaps that fail re-tests two weeks after closing. When a real-estate deal is on the clock, we schedule mitigation around your closing date — not our convenience.

Call (000) 000-0000 for same-week scheduling, or request a written quote online in under two minutes.

Most radon contractors won't print their Ohio license number on their website. We lead with ours: RC202. That license means our mitigators have passed Ohio Department of Health training, carry the required insurance, and install systems that meet Ohio Administrative Code 3701-69. Here's what that translates to in the field:

• Closing-deadline turnaround. We hold install slots specifically for real-estate transactions. Test Monday, install Thursday, re-test Friday — closing stays on calendar.
• Transparent, written pricing. Most Dayton mitigation systems fall between $1,295 and $1,895 depending on foundation type, run length, and exterior finish. You get the number in writing before we touch the house.
• Permanent systems, not band-aids. Schedule 40 PVC, ANSI-rated radon fans (RadonAway, Festa), manometer, labeling, sealed sumps — the full code-compliant build.
• Multi-vertical credibility. We mitigate Ohio schools, apartment complexes, and commercial buildings. If a school district trusts our work, your Belmont bungalow is straightforward.
• Aesthetic-first routing. The #1 homeowner objection is "I don't want an ugly pipe on the front of my house." We route through garages, interior chases, and rear elevations whenever the physics allow.

That's the difference between hiring a licensed Ohio specialist and a general contractor with a borrowed fan.

Every Dayton home is different — slab-on-grade in Huber Heights, full basement in Oakwood, crawlspace in rural Miami Township. Our service menu covers all of them.

48-hour continuous radon monitor (CRM) tests using calibrated Sun Nuclear and Radalink devices. Tamper-proof, court-admissible, accepted by every lender and title company in Montgomery, Greene, and Warren counties. Results delivered as a signed PDF within hours of test pickup.

The gold standard for basement and slab homes. We core a 5-inch suction point through the slab, run sealed Schedule 40 PVC to an exterior or attic-mounted ANSI fan, and discharge above the eave per code. Typical post-mitigation readings: under 2.0 pCi/L, often under 1.0.

For homes in Germantown, Brookville, and rural Dayton with vented crawls, we install 20-mil reinforced vapor barrier sealed to the foundation walls with a depressurization point underneath. Solves radon and moisture in one pass.

Multi-suction systems for large slabs, classroom buildings, and multifamily properties. We handle the Ohio Department of Health reporting, occupant communication, and post-mitigation verification testing required for institutional compliance.

Bought a house with a non-functioning system? Manometer stuck at zero? Fan humming but radon still high? We diagnose, rebuild, or replace — and document everything for your file.

Designed for speed and for the realtor calendar.

1. Site Diagnostic (Day 1). A licensed RC202 technician walks the property, identifies foundation type, slab penetrations, and the cleanest discharge route. You get a written, fixed-price quote before we leave.
2. Install (Day 2–4). One crew, one day, in most single-family Dayton homes. Core drill, pipe routing, fan mounting, electrical tie-in, manometer, labels, and caulked seal of every visible slab crack and sump.
3. Post-Mitigation Test (Day 5–7). 48-hour CRM test confirms the system pulled radon below 4.0 pCi/L. Almost always well below 2.0.
4. Closing Package. Signed test report, system warranty, ODH-compliant labeling photos, and the paperwork your title company needs. Sent same-day to your agent.

Total elapsed time on a standard transaction: 5 to 7 business days from first call to closing-ready documentation.

We work the entire Miami Valley — from Vandalia and Englewood north of I-70, through Trotwood and West Dayton, into Oakwood, Kettering, Centerville, Beavercreek, Bellbrook, Springboro, and out to Xenia and Fairborn. We know the soil signatures by zip code.

Oakwood and Hills & Dales pre-war homes with stone foundations almost always need exterior-routed systems with sealed rim joists. Centerville and Washington Township homes built in the '70s and '80s on shallow basements respond beautifully to single-point sub-slab systems. Huber Heights and Riverside slab homes often require interior suction points cored through utility closets. Crawlspaces in the rural southern townships need encapsulation before depressurization will work at all.

That kind of pattern recognition only comes from doing this work in Dayton specifically, not from a national franchise script. We've mitigated near the Air Force Museum, on Far Hills Avenue, in the historic St. Anne's Hill district, and in subdivisions along Yankee Trace. We know which builders left gravel beds (great for suction) and which poured slabs directly on clay (challenging — but solvable).

Straight numbers. No "call for pricing" games.

• Standard basement system (most Dayton homes): $1,295 – $1,595
• Slab-on-grade single suction point: $1,495 – $1,795
• Crawlspace encapsulation + mitigation: $2,495 – $3,995 depending on square footage
• Post-mitigation 48-hour CRM test: $150 (waived when bundled with install)
• Pre-purchase real-estate radon test: $150
• Commercial / multi-suction systems: Quoted after site visit

Financing available. Every system includes a 5-year workmanship warranty and a 5-year fan warranty from the manufacturer.
