West Unity sits in Williams County, one of the Ohio counties the EPA flags as Zone 1 — predicted average indoor radon levels above 4.0 pCi/L. That isn't marketing language. That's the federal map. If you own a home off State Route 20A, near Hilltop schools, or on the older farmsteads outside the village, there is a real statistical chance your basement or crawlspace is holding radon above the EPA action level.

Radon Eliminator is Ohio's licensed radon authority — Ohio Mitigation License RC202 — and we handle Radon Testing West Unity OH homeowners, buyers, sellers, and real-estate agents trust to hold up at the closing table. We don't sell fear. We sell a number, a clear next step, and a system that passes a re-test.

• RC202 Ohio-licensed — the license number competitors hide, we lead with
• 48-hour testing turnaround built around real-estate closing windows, not contractor calendars
• EPA-aligned protocols — continuous radon monitors (CRMs) and short-term test devices used per ANSI-AARST MAH-2019 standards
• Multi-vertical proof — the same team that tests Ohio schools, apartment complexes, and commercial buildings handles your West Unity basement
• Transparent, written pricing — no shifting quotes, no surprise add-ons

When a home inspector hands a West Unity buyer a number above 4.0 pCi/L, the deal doesn't have to die. It just needs the right contractor on the phone.

Not every test is the same. The right device, the right duration, and the right placement depend on whether you're a homeowner curious about your basement, a seller under a 10-day contingency, or a school district that has to document compliance. Here's what professional Radon Testing West Unity looks like when we run it.

This is the test buyers' agents request during the inspection period. We deploy a continuous radon monitor (CRM) — the same device EPA protocols prefer for transactional testing because it logs hourly readings and is tamper-resistant. Minimum 48-hour test under closed-house conditions, full report delivered as a signed PDF with the device serial number, calibration date, and our RC202 license. Lenders accept it. Title companies accept it. Buyer's agents stop asking questions.

If you're not in a transaction but you saw the Williams County radon map and got nervous, this is the right starting point. A short-term test (2 to 7 days) tells you whether you're below the EPA action level of 4.0 pCi/L or whether mitigation is the next conversation. Affordable, accurate, and scheduled around your week — not ours.

Radon levels swing with weather, frost depth, and how often you run the furnace. Long-term testing gives you an annual average — the most accurate picture of actual exposure. Recommended after a borderline short-term result (between 2.0 and 4.0 pCi/L) or for families who want certainty before finishing a basement.

Ohio law and ANSI-AARST MAMF-2017 / MALB-2014 standards require specific device counts and placements for apartment buildings, daycares, and schools. We handle the documentation, the device grid, and the chain-of-custody. If your West Unity property is a rental portfolio, a commercial building near downtown, or a school facility, we test to the standard a state inspector will accept.

If we installed a mitigation system — or if another contractor did and you don't trust the result — we run an independent post-mitigation test to confirm the home is under 4.0 pCi/L. This is the test that closes the loop with the buyer, the lender, and the disclosure form.

We've kept this deliberately simple because the people calling us are usually under deadline pressure. Here's exactly how a professional Radon Testing West Unity OH job runs from first call to signed report.

Call us. We ask three questions: Is this for a real-estate transaction? What's your closing date? What's the address? In most West Unity cases we can have a technician on site within 24 to 48 hours.

We place the monitor in the lowest livable level — typically the basement — per EPA protocol. Closed-house conditions start 12 hours before the test and run through it. We leave clear written instructions for the homeowner so the test isn't invalidated by an open window.

The CRM logs radon levels hourly. This matters because a single grab sample can miss the picture, but a 48-hour curve shows whether radon is consistently above 4.0 pCi/L or spiking with weather.

We retrieve the device, download the data, and deliver a signed report — usually within 24 hours of pickup. The report includes the hourly graph, the average pCi/L, the device serial and calibration date, our RC202 license number, and a plain-English summary of what the number means.

If you're under 4.0 pCi/L, we tell you so and you're done. If you're over, we give you a written mitigation quote the same day and — for transactions — we can typically install a permanent, code-compliant system within the same week. Learn more about our radon mitigation systems.

West Unity is a small village in Brady Township, Williams County, near the Indiana and Michigan borders. The geology here — glacial till over fractured limestone and shale — is exactly the kind of subsoil that produces elevated indoor radon. Williams County's EPA-predicted average is above 4.0 pCi/L, putting it in the highest-risk federal zone alongside neighboring Defiance, Fulton, and Henry counties.

We test homes throughout West Unity proper, the rural properties along County Roads M and 19, the older housing stock near Hilltop High School, and newer builds on the village's south side. We also serve nearby communities — Bryan, Montpelier, Pioneer, Edon, Stryker, and Archbold — under the same 48-hour turnaround commitment.

What makes Radon Testing West Unity near me different from generic national chains: we know the housing stock. Pre-1980 farmhouses with fieldstone foundations behave differently than 1990s ranches with poured concrete basements. Crawlspaces over dirt — common in older West Unity homes — read higher than sealed slabs. When we look at your number, we're reading it against years of testing in this exact soil and this exact climate.

For real-estate professionals: we run a home inspector and realtor referral program built specifically for the West Unity / Williams County market. Ask about it when you call. Most of our competitors ignore the referral lane entirely.

One of the most common complaints we hear from West Unity homeowners is that every contractor quotes a different price. Here's our straight answer:

• Real-estate transaction test (48-hour CRM): typically $150 to $200, report included
• Homeowner short-term test: typically $125 to $175
• Long-term test kit: generally under $50
• Commercial / multi-family / school testing: quoted per device count and square footage — call for a written estimate
• Post-mitigation verification: often included when we install the system

If a contractor quotes you $75 for a transactional test, ask whether they're an Ohio-licensed radon professional and which device they're using. Affordable Radon Testing West Unity OH doesn't mean cheap — it means defensible, documented, and accepted by lenders the first time.
