If you're searching for Radon Testing in Gordon OH, you're usually in one of three situations: the home inspector's report flagged elevated radon and your closing is days away, you just read that Ohio has some of the highest radon levels in the country, or your insurance carrier or school district is requiring a documented test. Radon Eliminator handles all three — and we do it on your timeline, not ours.

We are Ohio's licensed radon authority (Ohio Radon Mitigation License RC202), and radon is the only thing we do. Not HVAC. Not basement waterproofing. Just EPA-aligned testing and permanent, code-compliant mitigation across residential, commercial, real-estate, school, and apartment properties throughout Gordon, Greenville, Versailles, Ansonia, and the surrounding Darke County communities.

Call (937) 884-8090 for same-week deployment, or request a written quote online. No call-for-pricing games. No fear-mongering. Just clear numbers, fast results, and documentation your title company and lender will accept.

Gordon sits in a region of western Ohio where Zone 1 and Zone 2 EPA radon designations overlap — meaning average indoor radon levels frequently exceed the EPA action threshold of 4.0 pCi/L. Local geology (glacial till over limestone bedrock) drives uranium decay gas straight into basements and crawlspaces. That's not a sales pitch; it's why testing matters here.

• Ohio License RC202 — published openly on every quote, invoice, and test report. Most local competitors won't show you theirs.
• 48-hour EPA-aligned testing using continuous radon monitors (CRMs), not mail-in charcoal kits that take a week to return results.
• Real-estate transaction speed — we time test deployment, retrieval, and reporting to your closing date. We won't blow up your deal.
• Transparent pricing — residential short-term tests start at clearly published rates. No bait-and-switch upsells.
• Multi-vertical capability — single-family homes, commercial buildings, schools, and multifamily apartment complexes that require compliance-grade documentation.
• Home inspector referral program — Gordon-area inspectors get a named Special Offer and priority scheduling for their clients.

We don't sell one generic test. The right protocol depends on whether you're closing a sale, monitoring a school, or trying to protect kids who sleep in a basement bedroom. Below are the professional Radon Testing Gordon OH services we deploy most often.

This is our most-requested service in Gordon. We deploy a calibrated continuous radon monitor for a minimum of 48 hours under closed-house conditions per EPA protocol, retrieve the device, and deliver a signed PDF report your lender, title company, and buyer's agent will accept. Most tests are placed within 24-48 hours of your call. Reports include hourly pCi/L readings, temperature, humidity, and barometric pressure — the data points underwriters look for.

If you're not in a transaction and want the most accurate picture of your year-round exposure, long-term alpha-track detectors measure radon across seasons. Radon levels in Gordon homes typically spike in winter (closed windows, stack-effect drawing soil gas upward) and drop in summer. We recommend long-term testing for any homeowner whose short-term result fell between 2.0 and 4.0 pCi/L.

Ohio commercial property owners, school districts, and apartment landlords carry legal responsibility for safe indoor air. We perform multi-point testing using ANSI/AARST MAH-2019 and MALB-2014 protocols — the standards Ohio Department of Health and most lenders require for non-residential properties. Documentation includes device placement diagrams, chain-of-custody, and a stamped report signed by our RC202-licensed technician.

After any radon mitigation system is installed — by us or another contractor — a follow-up test is required to confirm the system reduced levels below 4.0 pCi/L. We perform independent verification tests and provide the certificate your buyer or inspector will want before signing.

If your Gordon-area home uses a private well — common throughout rural Darke County — radon can dissolve into the water supply and release into the air during showering, dishwashing, and laundry. We collect water samples and submit them to a certified lab for radon-in-water analysis.

Every test we run in Gordon follows the same documented sequence. Predictable, repeatable, defensible.

1. Schedule & Scope (Day 0) — Call (937) 884-8090 or submit our online form. We confirm the property type, your closing or compliance deadline, and quote a fixed price before we dispatch.
2. Device Placement (Day 1) — A licensed technician places a calibrated continuous radon monitor in the lowest livable level of the home — typically a finished basement, lowest bedroom, or ground-floor living space. We document closed-house conditions and start the 48-hour measurement window.
3. Retrieval & Lab-Grade Analysis (Day 3) — We retrieve the device, download hourly data, and verify the test wasn't tampered with (CRMs detect motion and pressure changes that invalidate charcoal kits).
4. Report Delivery (Day 3-4) — You receive a signed PDF report by email, typically within 24 hours of retrieval. If levels exceed 4.0 pCi/L, we provide a written mitigation quote in the same email so you can keep your transaction moving.

Gordon is a small village in Darke County, just south of Greenville along State Route 49. The surrounding agricultural landscape — flat farmland over glacial deposits and limestone — is exactly the geology that produces elevated indoor radon. The Ohio Department of Health classifies most of Darke County as Zone 1 (predicted average indoor radon screening level greater than 4.0 pCi/L).

We regularly test homes throughout Gordon, Hollansburg, New Madison, Palestine, Arcanum, and the broader Greenville area. Older farmhouses with fieldstone foundations, mid-century ranches with block-wall basements, and newer builds with sealed slabs all show different radon entry patterns — and we adjust placement protocol accordingly. Properties near Bear Creek and the Greenville Creek watershed sometimes show elevated radon-in-water readings on private well systems, which is why we offer water testing as an add-on.

For real-estate professionals working transactions in the Greenville City Schools and Tri-Village Local Schools districts, we maintain priority scheduling slots specifically to protect closing dates. If you're an agent, broker, or home inspector who'd like to set up a referral relationship, ask about our Inspector Special Offer when you call.

One of the most common complaints we hear about other radon companies: "They wouldn't tell me the price until I gave them my address." We don't operate that way.
