Radon Testing in Greene OH is not a side hustle for us. It's the entire business. Radon Eliminator holds Ohio Department of Health Mitigation License RC202, and we deploy EPA-aligned continuous radon monitors that produce defensible, real-estate-ready results in 48 hours — not the 5-to-7-day window most general home inspectors quote.

Greene County sits squarely inside the elevated radon belt that runs through southwest Ohio. The EPA classifies Greene as a Zone 1 county, meaning the predicted average indoor radon screening level exceeds 4.0 pCi/L — the action threshold at which mitigation is recommended. Homes in Beavercreek, Xenia, Fairborn, Bellbrook, Yellow Springs, Jamestown, and Cedarville routinely test above that line, especially properties built on the limestone-rich soils common throughout the Little Miami River watershed.

If your inspector flagged radon mid-transaction, if you're a listing agent who needs a clean test before going active, or if you manage an apartment building or school that needs compliance documentation, you're in the right place. We don't blow up closings. We don't pad invoices. And we don't hide behind "call for pricing."

Most companies advertising radon services in the Dayton metro are HVAC contractors, basement waterproofers, or general inspectors who added radon as a sideline. We are the opposite. Radon mitigation and testing is the only thing we do, and we do it under Ohio license RC202 with a chain-of-custody process that holds up in a real estate transaction.

• Licensed Ohio Radon Specialist (RC202) — Not a general contractor with a side service. Our license number is printed on every report.
• 48-Hour Real Estate Testing — Continuous radon monitors deployed and retrieved on a schedule that matches your inspection contingency, not ours.
• Transparent, Published Pricing — Residential radon tests in Greene start at clear, flat-rate pricing. No "call for a quote" runaround.
• Multi-Vertical Capability — Residential closings, commercial buildings, apartment complexes, and K-12 schools. Most local radon outfits can't legally or operationally handle the commercial side.
• Closing-Deadline Promise — If radon is elevated, we can install a permanent, code-compliant mitigation system and re-test fast enough to clear your closing date.
• Home Inspector Referral Program — Named Special Offer for inspectors who refer radon work. Ask us about it.

That combination — licensed specialization, real-estate speed, transparent pricing, and commercial-grade capability — is why we're considered the best Radon Testing Greene homeowners and agents call when the clock is ticking.

We tailor the test to the situation. A casual homeowner check is not the same as a transactional test under EPA Protocol — and we don't pretend it is.

This is our most-requested service in Greene. We follow EPA Protocol for Real Estate Transactions: a sealed, tamper-evident continuous radon monitor (CRM) placed in the lowest livable area for a minimum 48-hour closed-house test. Results are timestamped, hour-by-hour, so buyers, sellers, lenders, and underwriters get data they can actually defend. Reports are typically delivered within 24 hours of pickup.

Smart Greene sellers test before listing. If radon is elevated, you mitigate on your timeline — not under the pressure of a 10-day inspection clock. We help listing agents in Beavercreek, Xenia, and Sugarcreek Township stage clean radon documentation alongside the rest of the disclosure packet.

Multi-family properties, daycare facilities, K-12 schools, and commercial buildings have different testing protocols — typically AARST-NRPP MAH (Multifamily and High-rise) or MAMF standards. We're one of the few Ohio-licensed firms equipped to deploy the device counts and documentation required for compliance-grade work. If you're a property manager or school administrator in the Greene County region, this is the affordable Radon Testing Greene OH solution that actually meets code.

After any radon mitigation system is installed — by us or anyone else — a follow-up test is required to confirm the system reduced indoor radon below 4.0 pCi/L. We perform independent post-mitigation testing with documented results for your closing file, lender, or compliance officer.

For homeowners who aren't in a transaction but want a more accurate annual-average reading, we offer 90-day to 12-month alpha-track or electret testing. Radon levels swing seasonally in Ohio — winter readings are often double summer readings — so long-term data gives you the true picture.

From the first phone call to a signed report, our process is built for the deadlines real estate runs on.

Call or submit the form. We confirm the property address in Greene, the test type required (transactional, pre-listing, commercial), and a placement window — usually within 24 hours.

For an EPA-protocol test, the home enters closed-house conditions 12 hours before placement: windows and doors closed except for normal entry/exit. We brief the homeowner or listing agent so the test isn't invalidated.

A calibrated continuous radon monitor is placed in the lowest livable level — typically a finished basement, lower-level bedroom, or first-floor living area on a slab. Tamper indicators are armed. GPS-timestamped photos document placement.

The monitor records radon, temperature, humidity, barometric pressure, and tilt every hour. Any tampering or condition violation shows up in the data.

We retrieve the device, download the data, and issue a sealed PDF report — usually within 24 hours. If the average is at or above 4.0 pCi/L, we walk you through mitigation options and pricing on the spot. If you're under contract, we coordinate directly with your agent to keep the deal on schedule.

Greene County, Ohio has a geology problem most homeowners don't know about. The bedrock under Beavercreek, Fairborn, Xenia, and Cedarville is a mix of Ordovician limestone and shale — formations that naturally contain uranium. As uranium decays, it produces radium, and radium decays into radon gas. That gas migrates up through soil, foundation cracks, sump openings, and unsealed slab penetrations into the living space.

The Ohio Department of Health has consistently reported Greene County indoor radon averages well above the EPA action level. Homes near Wright-Patterson Air Force Base, the older neighborhoods around downtown Xenia, the newer subdivisions in Sugarcreek Township and Bellbrook, and the rural properties around Jamestown all test high regularly. Even slab-on-grade ranches and homes without basements are not exempt — radon enters through any soil-contact surface.

What makes Greene especially tricky for testing is the mix of housing stock. You've got 1950s ranches with block foundations, 1990s walkouts on poured concrete, brand-new builds with passive radon roughed-in but never activated, and historic farmhouses with stone foundations and dirt crawlspaces. Each requires a different placement strategy. A national franchise that's never set foot in a Yellow Springs century home isn't going to know that. We do.

We serve all of Greene County including Beavercreek, Xenia, Fairborn, Bellbrook, Sugarcreek Township, Yellow Springs, Cedarville, Jamestown, Spring Valley, and Bowersville — and we cover the surrounding Dayton metro when transactions cross county lines.

We publish pricing because "call for a quote" is how customers get burned. Exact pricing depends on property type, square footage, and the number of devices required, but here's the honest range:

• Residential Real Estate Test (single device, 48-hour CRM): Flat-rate pricing in line with regional standards — typically $150–$200.
• Larger Homes (multiple devices required): Additional device fees apply for homes over 2,000 sq ft or with multiple foundation types.
• Commercial / Multi-Family / School Testing: Custom quote based on AARST device-count requirements. We provide written estimates the same day.
• Post-Mitigation Verification: Discounted when bundled with mitigation work we perform.
