Radon Eliminator provides Radon Testing in Addyston, OH for homeowners, buyers, sellers, real-estate agents, home inspectors, and commercial property owners who need accurate results — fast. We are a licensed Ohio radon contractor (Ohio Mitigation License RC202), and every test we run follows EPA testing protocols and Ohio Department of Health standards.

Addyston sits along the Ohio River in western Hamilton County, where the underlying limestone and shale geology produces some of the highest radon readings in the state. Ohio is a Zone 1 radon state on the EPA map, meaning predicted indoor radon averages above 4.0 pCi/L — the action level at which the EPA recommends mitigation. In Hamilton County specifically, roughly 1 in 3 homes tested shows elevated radon. If you live in Addyston, testing isn't optional due diligence — it's the only way to know what your family or tenants are breathing.

We test single-family homes off State Route 50, riverfront properties near the Ohio River, rentals throughout the village, and commercial buildings tied to the Three Rivers industrial corridor. When the deal closes in 10 days, we deliver. Call now to schedule your radon test.

Most contractors who offer radon testing in Addyston are HVAC companies or basement waterproofers who added radon as a sideline. We are different. Radon is the only thing we do, and we do it under a verifiable Ohio state license.

• Licensed Ohio radon professional — RC202. Our license number is published, traceable, and recognized by the Ohio Department of Health. Ask any competitor for theirs.
• Real-estate transaction speed. We schedule tests within 24-48 hours, deliver lab-grade reports your title company and lender will accept, and coordinate directly with your agent or inspector if needed. We don't blow up closings.
• EPA-aligned protocols. Closed-house conditions, proper placement (lowest livable level, away from drafts, 20+ inches off the floor), continuous radon monitors with hourly data — no shortcuts, no DIY canisters.
• Transparent, published pricing. No "call for a quote" runaround. You'll know what a Radon Testing service in Addyston costs before we pick up the phone.
• Multi-vertical experience. Residential, commercial, apartment complexes, and schools. Most local providers can't legally or operationally handle compliance-grade work — we can.
• Home inspector referral program. If an Addyston inspector referred you, ask about our Special Offer at booking.

We provide the full range of professional Radon Testing services Addyston OH property owners need — whether you're closing on a house next week or running a 200-unit apartment portfolio.

This is our specialty. When the inspection period is ticking and the buyer's lender, agent, or attorney needs a radon number on paper, we deliver a 48-hour continuous monitor test with a sealed, signed report acceptable to every Ohio title company and underwriter. We coordinate placement with the listing agent, comply with closed-house protocol, and email the PDF report the moment testing ends. If results come back above 4.0 pCi/L, mitigation can typically be installed and post-mitigation tested within the same contingency window.

For Addyston homeowners who want to know — whether the kids sleep in the basement, a neighbor was diagnosed with lung cancer, or you just saw a news story — we run a 48-hour continuous radon monitor test. Hourly readings, tamper detection, temperature/humidity logging. You receive a written report explaining your pCi/L average, your health risk in plain English, and exactly what (if anything) you should do next.

Ohio law and ANSI/AARST MA-MFLB and MAMF protocols require commercial-grade testing in multifamily and school environments — including ground-contact unit sampling ratios, written sampling plans, and chain-of-custody documentation. Most local radon outfits can't produce this paperwork. We can. We test apartment complexes, daycare facilities, schools, nursing homes, and commercial buildings across Addyston and the greater Cincinnati metro.

If you've had a mitigation system installed (by us or anyone else), Ohio requires a post-mitigation test to confirm the system is performing. We provide independent post-mitigation testing with documentation that satisfies real-estate, lender, and code-enforcement requirements.

For homeowners who tested borderline (2.0–4.0 pCi/L) and want a year-round average before deciding on mitigation, we deploy long-term alpha-track detectors and return for retrieval and lab analysis. This is the most accurate picture of true radon exposure in a home.

Every radon test we perform follows the same disciplined, EPA-aligned process. No shortcuts.

1. Schedule & confirm closed-house conditions. We call within hours of your inquiry, lock in a placement window, and email you the 12-hour closed-house instructions required for valid testing.
2. Deploy a calibrated continuous radon monitor. Our technicians place the device in the lowest livable level per EPA siting rules — not the crawlspace, not a closet — and log placement photos and conditions.
3. 48-hour active sampling. The monitor records hourly pCi/L readings, temperature, humidity, barometric pressure, and tamper events. This is laboratory-grade data, not a charcoal canister you mail away.
4. Retrieve, analyze, and deliver report. We pull the device, generate the signed PDF report, and email it the same day. You'll see your average pCi/L, hourly graph, and a clear recommendation.
5. Next-step consult (if needed). If your home tests at or above 4.0 pCi/L, we walk you through mitigation options, exact pricing, and timeline. If you're mid-closing, we can typically install a code-compliant mitigation system within 3-5 business days.

Addyston is a small Ohio River village of roughly 1,000 residents bordered by North Bend, Cleves, and the Three Rivers school district. The housing stock is a mix of early-1900s riverfront homes, mid-century ranches off Main Street and Three Rivers Parkway, and newer construction toward US-50. What ties them together is geology: the Cincinnati Arch beneath this part of Hamilton County produces uranium-bearing shale that releases radon into basements and crawlspaces year-round.

We've tested and mitigated homes throughout the western Cincinnati corridor — Addyston, Cleves, North Bend, Sayler Park, Delhi, Hooven, and Miamitown. We know which neighborhoods sit on the limestone shelf that drives readings into the double digits, and we know which slab-on-grade subdivisions need sub-slab depressurization versus sub-membrane systems for crawlspaces. That local pattern recognition is something a national franchise or a general HVAC contractor simply can't match.

If you're a real-estate agent working Addyston listings, a home inspector covering the western suburbs, or an apartment owner with units along River Road, you have a licensed Ohio radon specialist 20 minutes away.

We publish pricing because you shouldn't have to call three companies to find out what a Radon Testing service in Addyston OH actually costs.
