Radon Testing Near Me in Cleves, OH | Radon Eliminator

Cleves sits in Hamilton County along the Great Miami River — and like most of southwest Ohio, it's built on glacial till and limestone bedrock that quietly produces some of the highest indoor radon concentrations in the United States. The EPA places Hamilton County in Zone 1, the highest-risk designation, with predicted average indoor levels above 4.0 pCi/L. That's the action threshold. That's also why Radon Testing Near Me Cleves OH searches spike every time an inspection report comes back with a number a buyer doesn't recognize.

Radon Eliminator is a licensed Ohio radon contractor — license RC202 — that does one thing: test for radon and install permanent, code-compliant mitigation systems. We are not an HVAC company that dabbles in radon. We are not a basement waterproofer cross-selling fans. We are the licensed specialist your home inspector, your real estate agent, and your closing attorney call when the clock is ticking.

• RC202 Ohio Mitigation License — published openly, verifiable through the Ohio Department of Health.
• 48-hour EPA-aligned testing using continuous radon monitors (CRMs) with tamper detection — not mail-in charcoal kits.
• Closing-deadline scheduling — we slot real estate transactions ahead of routine appointments because we know what a delayed test costs.
• Transparent, published pricing — no "call for a quote" runaround. You'll know the number before you hang up.
• Multi-vertical capability — residential, commercial, school district, and multi-family apartment testing under one licensed roof.

Every property in Cleves — from the older brick homes near Miami Avenue to the newer builds out toward Whitewater Township and the developments off Buffalo Ridge Road — has a different radon profile. Soil composition, foundation type, basement finish, and HVAC behavior all shift the reading. Our testing protocols are built to capture an accurate, defensible number the first time.

Real Estate Transaction Radon Testing

This is the wedge. When a deal is on the line and the inspection contingency closes in seven days, you cannot afford a slow test, a lost result, or a technician who doesn't understand the difference between a measurement test and a clearance test. Our real estate testing is a 48-hour continuous monitor deployment with same-day report delivery to the buyer's agent, seller's agent, and inspector. We document closed-house conditions, deploy in the lowest livable area per EPA Protocol, and provide a signed PDF report that title companies and lenders accept without question.

Residential Radon Testing for Cleves Homeowners

If you're not in a transaction — you just read about radon, your neighbor in Three Rivers tested high, or your kids sleep in a finished basement — this is the test for you. We use the same continuous monitor, the same EPA protocol, and provide the same report. The only difference is we can usually schedule within a week instead of moving heaven and earth for a closing date.

Commercial, School, and Apartment Building Radon Testing

Ohio commercial property owners, school districts, and multi-family operators carry a legal duty of care for occupant safety. We perform multi-point testing campaigns sized to ANSI/AARST MA-MFLB and MALB protocols, with chain-of-custody documentation suitable for regulatory submission, insurance files, and tenant disclosure. This is the work most local radon outfits cannot legally or operationally handle. We can.

Post-Mitigation Clearance Testing

If a mitigation system was installed by another contractor and you need an independent post-installation test — or you're buying a home where the seller installed a system and you want it verified — we provide independent clearance testing. We do not pressure you into a re-install. We give you the number and the data.

Long-Term Radon Monitoring

Radon levels fluctuate seasonally. Winter levels in Cleves typically run 30–50% higher than summer levels because closed houses concentrate soil gas. For homeowners who tested in the borderline range (2.0–3.9 pCi/L) or want ongoing confidence, we offer 90-day and 12-month alpha-track monitoring with annual reporting.

There is no mystery to a good radon test, but there is a method. Skipping a step skews the result, and a skewed result either kills a sale that didn't need killing or clears a house that wasn't safe. Here's how we run every test.

Step 1: Schedule and Closed-House Setup

You call, we book — often within 24–48 hours for real estate clients. We explain closed-house conditions: windows closed, exterior doors used only for normal entry/exit, HVAC operating normally. Closed-house begins 12 hours before deployment.

Step 2: Continuous Monitor Deployment

Our technician arrives, identifies the lowest livable area (typically the basement in Cleves homes, occasionally a slab-on-grade living space), and places a calibrated continuous radon monitor on a stable surface at breathing height, away from drafts, exterior walls, and HVAC supply vents. Deployment time, location, and conditions are logged.

Step 3: 48-Hour Measurement

The CRM samples radon hourly for a minimum of 48 hours. Continuous monitors also track temperature, humidity, barometric pressure, and tilt — meaning we can detect tampering or environmental anomalies that would invalidate a charcoal kit.

Step 4: Retrieval, Analysis, and Reporting

We retrieve the monitor, download the data, and produce a signed PDF report with the hourly trace, the 48-hour average in pCi/L, EPA action-level context, and a recommendation. Real estate reports go out same-day. Homeowner reports within 24 hours.

Step 5: Next Steps — Mitigation or Peace of Mind

If the result is below 4.0 pCi/L, you're done (we'll note if you're in the 2.0–3.9 range where the EPA suggests considering mitigation). If the result is 4.0 pCi/L or higher, we provide a mitigation quote on the same call — published pricing, no upsell theater. Learn more about our radon mitigation systems.

Cleves and the surrounding Miami Township area sit on a geological cocktail that produces radon: uranium-bearing limestone, fractured shale, and porous glacial outwash deposits along the Great Miami River valley. Homes near Shawnee Lookout, in the neighborhoods feeding into Three Rivers Local Schools, and the older housing stock along U.S. 50 and State Route 128 frequently test above 4.0 pCi/L. We've seen results above 20 pCi/L in basements within five miles of downtown Cleves — that's five times the action level.

Hamilton County as a whole reports roughly 40% of tested homes exceeding the EPA action threshold, according to Ohio Department of Health data. That's not a scare statistic — it's the baseline you should assume until your specific house proves otherwise. The only way it proves otherwise is a test.

We test homes across Cleves, North Bend, Addyston, Miamitown, Harrison, Hooven, and the broader western Hamilton County corridor. We're familiar with the foundation types common to the area — older block-and-mortar basements that leak soil gas through the cove joint, mid-century slab pours with cold joints, and newer poured-wall basements with sump pits that act as radon entry points. Each foundation gets tested and, when needed, mitigated differently. That's the kind of detail you only get from a licensed radon specialist who works this geography every week.

Most radon companies hide pricing because their pricing changes based on what they think you'll pay. Ours doesn't. Here's the structure:

• Standard 48-Hour Residential Test: flat fee, includes deployment, retrieval, signed PDF report.
• Real Estate Transaction Test: same protocol, prioritized scheduling, same-day report delivery to all parties.
• Post-Mitigation Clearance Test: independent verification of an existing system.
• Commercial / Multi-Family / School Testing: quoted per device count and protocol — published per-device pricing, no mystery markups.
• Long-Term Alpha-Track Monitoring: 90-day and 12-month options at homeowner-friendly pricing.
