Ohio sits in EPA Radon Zone 1 — the highest-risk category in the country. Hardin County and the broader Ada area regularly produce home test results well above the EPA action level of 4.0 pCi/L. Radon is a colorless, odorless radioactive gas that seeps up from the soil through foundation cracks, sump pits, and slab penetrations. It is the second-leading cause of lung cancer in the United States and the leading cause among non-smokers.

If you live in Ada, your home was almost certainly built over uranium-bearing limestone and glacial till — the exact geology that drives radon indoors. Older homes near downtown Ada, newer builds off Lima Avenue, farmhouses on the edge of Hardin County, and even properties near Ohio Northern University have all tested high in our experience. The only way to know your number is to test.

Radon Eliminator is Ohio's licensed radon authority (Ohio Mitigation License RC202) providing EPA-aligned Radon Testing in Ada OH for residential, commercial, school, and apartment properties. We don't moonlight as an HVAC or waterproofing company — radon is all we do. Call (330) 555-1234 to schedule a test today.

Most Ada-area homeowners discover us in one of three ways: their home inspector flagged elevated radon during a real estate transaction, a neighbor was diagnosed with lung cancer, or they read an Ohio Department of Health bulletin about radon zones. Whatever brought you here, here's why we're the right call:

• Ohio Licensed — RC202. We publish our license number because not every "radon guy" actually has one. Ohio law requires a license to test and mitigate. We hold it. Ask any competitor for theirs.
• Real estate closing speed. Inspection came back hot and you close in 10 days? That's our specialty. We schedule testing within 24–48 hours and deliver lab-grade results in time to renegotiate or remediate before signing.
• EPA-aligned protocols. Continuous radon monitors (CRMs), proper closed-house conditions, tamper-evident placement, and chain-of-custody documentation that holds up with lenders, attorneys, and underwriters.
• Transparent, published pricing. No "call for a quote" runaround. You'll know the cost of Radon Testing services in Ada OH before we set foot on your property.
• Multi-vertical expertise. Single-family homes, commercial buildings, apartment complexes, and schools — we handle compliance-grade testing most local outfits can't legally or operationally take on.

We offer the full range of professional Radon Testing in Ada OH — calibrated, documented, and defensible. Whether you're a worried homeowner, a buyer mid-transaction, or a property manager facing a compliance deadline, there's a test designed for your situation.

This is the test most Ada buyers and sellers need. We deploy a continuous radon monitor for a minimum of 48 hours under closed-house conditions, then deliver a signed, lab-quality report with hourly readings, average pCi/L, and any anomalies. The report is formatted for lenders, title companies, and inspectors. If results come back above 4.0 pCi/L, we can quote mitigation on the same call.

If you're not in a transaction and just want a true picture of year-round exposure, we offer 90-day to 12-month testing using alpha-track detectors. This is the most accurate option for homes where occupants spend significant time in lower levels — especially Ada families with finished basements or bedrooms below grade.

Apartment complexes, schools, daycares, and commercial buildings carry legal exposure if radon levels exceed action thresholds. We perform large-scale testing protocols (AARST-NRPP MAMF and MALB standards) for property managers, school districts, and commercial owners across Hardin County and the surrounding region. Documentation is built for regulators, insurers, and boards of directors.

If you've already had a mitigation system installed — by us or anyone else — a follow-up test is required to confirm it's working. We provide independent verification testing so you know your system is actually pulling radon below 4.0 pCi/L (and ideally below 2.0).

Ada-area home inspectors: we run a referral program with a named Special Offer for your clients and a streamlined scheduling channel that respects your timelines. Inspectors who work with us close more deals because we don't blow up closings. Call us to enroll.

Here's exactly what happens when you book the best Radon Testing in Ada with us:

1. Phone consultation (10 minutes). We confirm property type, occupancy, basement/crawlspace status, and your timeline. If you're in a real estate deal, we ask for the closing date first.
2. On-site deployment. A licensed technician places a continuous radon monitor in the lowest livable level of your Ada home — typically the basement or ground floor — following EPA placement guidance (away from drafts, exterior walls, and HVAC vents).
3. Closed-house conditions. We give you a one-page protocol: windows and exterior doors closed except for normal entry/exit, HVAC operates normally. This is non-negotiable for a defensible result.
4. 48-hour data collection. The monitor records hourly readings, tracks temperature, humidity, and tilt (so we know if it was moved). No paper canisters, no guesswork.
5. Report delivery. Within 24 hours of monitor retrieval, you receive a PDF report with average pCi/L, hourly chart, technician signature, and license number. If you need mitigation, we quote it on the spot — flat, written, and code-compliant.

Ada sits in northwest Ohio's Hardin County, an area defined by glacial drift over Silurian limestone — bedrock that naturally produces uranium decay and, downstream, radon gas. We've tested homes from the historic neighborhoods around Main Street and Johnson Avenue, to newer subdivisions south of US-30, to farmhouses out past Ohio Northern University and along County Road 175.

What we see consistently: older Ada homes with stone foundations and dirt-floor crawlspaces test high because there's nothing between the soil and the air you breathe. Newer slab-on-grade builds can test even higher if the sub-slab gravel layer wasn't sealed properly. Even modern homes near ONU's campus housing footprint have surprised owners with elevated numbers.

We also serve the surrounding communities — Kenton, Lima, Bluffton, Findlay, and Bellefontaine — and have an established Ohio presence with crews operating out of Akron, Columbus, Cleveland, Canton, and the broader state. When you search Radon Testing Ada near me or top Radon Testing Ada OH, you're looking for someone who knows this specific soil, this specific building stock, and this specific market. That's us.
