Ohio sits on some of the highest natural radon levels in the United States. The EPA classifies most of Ohio — including Allen County and the surrounding Lima region — as Zone 1, the highest possible radon risk category. That means the average indoor radon screening level in this part of the state regularly exceeds 4.0 pCi/L, the threshold at which the EPA recommends mitigation.

Radon Testing in Allen OH is not optional during a real estate transaction. It's the only way to know whether the home you're buying, selling, or already living in is exposing your family to a Class A human carcinogen. Radon is the second leading cause of lung cancer in the U.S. and the number one cause among non-smokers, according to the Surgeon General.

Radon Eliminator is Ohio's licensed radon authority (Ohio Mitigation License RC202). We don't sell HVAC, we don't waterproof basements, and we don't do radon as a side service. Radon testing and mitigation is all we do — for residential homeowners, real estate agents under deadline, school districts, apartment owners, and commercial property managers across Allen County, Lima, Elida, Bluffton, Delphos, and Spencerville.

• Licensed Ohio professional (RC202) — not a contractor moonlighting
• 48-hour EPA-aligned testing timed to closing deadlines
• Transparent pricing — published on our site, not hidden behind a phone call
• Real estate transaction specialists — we work with agents, inspectors, and title companies daily
• Commercial-grade capability for apartments, schools, and multi-tenant properties

There are plenty of companies in northwest Ohio that will hang a radon monitor in your basement. Very few are actually licensed by the Ohio Department of Health to do it correctly, interpret the results, and follow through with code-compliant mitigation if the numbers come back hot. We are.

Licensed Ohio Radon Specialist — RC202

Our Ohio Mitigation License number is RC202. We publish it openly because Ohio law requires anyone testing radon for a real estate transaction or installing a mitigation system to be licensed. If a competitor won't show you their license number, that's your answer.

Real Estate Transaction Speed

If your inspection just came back showing elevated radon and you're 10 days from closing, you don't have time for a contractor who books out three weeks. We schedule transaction testing within 24-48 hours and can pivot directly into mitigation installation if results require it — often without delaying your closing date.

The Best Radon Testing Allen Property Owners Can Buy

We use continuous radon monitors (CRMs) that record hourly readings over the EPA-required minimum 48-hour test window. You get a tamper-evident, court-admissible report with hourly graphs — not a back-of-envelope number. This is the professional Radon Testing Allen OH standard real estate attorneys and lenders trust.

Affordable Radon Testing in Allen Without Sacrificing Accuracy

We publish flat-rate pricing for residential testing. No "call for a quote" games. Affordable Radon Testing Allen homeowners deserve transparent numbers up front, and that's what we deliver — whether you're testing a 1,200 sq ft ranch in Allentown or a 6,000 sq ft estate in Shawnee Township.

Multi-Vertical Compliance Experience

School districts, apartment complexes, and commercial property owners in Ohio have legal exposure most people don't realize. We perform compliance-grade testing protocols for HUD properties, Ohio Department of Education facilities, and multi-unit residential buildings — work that requires documentation most local radon guys can't legally produce.

Not every radon test is the same. The right test depends on whether you're in a real estate transaction, doing a wellness check on your home, or meeting compliance requirements for a commercial property. Here's what we offer Allen County clients:

Real Estate Transaction Testing (48-Hour)

This is the EPA-protocol short-term test required during a home sale. We deploy a continuous radon monitor (CRM) for a minimum of 48 hours under closed-house conditions, then deliver a sealed, dated report suitable for your buyer's agent, lender, and title company. Results typically delivered within hours of pickup.

Long-Term Homeowner Testing (90+ Days)

For homeowners not under a transaction deadline, long-term tests give the most accurate picture of year-round radon exposure. Radon levels fluctuate seasonally — Ohio winters typically show the highest readings because homes are sealed up tight. A 90-day test removes that seasonal guesswork.

Post-Mitigation Verification Testing

After a radon mitigation system is installed (by us or anyone else), the EPA requires a post-installation test to confirm levels have dropped below 4.0 pCi/L. We perform verification testing as a standalone service for homeowners who had a system installed elsewhere and want independent confirmation it's working.

Commercial, School & Multi-Family Testing

Ohio schools, daycares, apartment complexes, and commercial buildings have specific protocols (often based on ANSI/AARST MAH-2019 or MALB-2014 standards) that require multiple monitor placements and documented chain-of-custody. We handle the entire compliance package — placement, retrieval, lab analysis, and certified reporting.

Radon in Water Testing

For Allen County homes on private well water — common in rural areas around Lafayette, Harrod, and Beaverdam — radon can enter the home through water as well as soil gas. We coordinate water sampling alongside air testing when well water is the supply source.

Whether you found us by searching "Radon Testing near me" or were referred by a home inspector, here's exactly what to expect when you book with Radon Eliminator:

Step 1: Schedule (Same-Day or Next-Day Availability)

Call us or fill out the form. For transaction work, we'll prioritize your scheduling around your closing date — not ours. Most Allen County tests can be deployed within 24-48 hours of your first call.

Step 2: Monitor Deployment

A licensed technician arrives, walks the property, and places a continuous radon monitor in the lowest livable level of the home (typically a finished basement or first floor over slab). We'll explain closed-house conditions and what you need to do for the next 48 hours.

Step 3: 48-Hour Measurement Period

The CRM records hourly radon readings, temperature, humidity, and barometric pressure — data that proves the test wasn't tampered with. This is the EPA-recommended minimum protocol for real estate transactions.

Step 4: Retrieval & Reporting

We retrieve the monitor, download the data, and deliver a professional report — usually the same day. The report includes hourly readings, the average pCi/L result, and a clear recommendation: action needed (≥4.0 pCi/L) or no action needed.

Step 5: Mitigation Pathway (If Needed)

If results come back elevated, we provide a flat-rate mitigation quote on the spot. For transaction clients on tight timelines, we can often install a permanent, code-compliant active soil depressurization system within 3-5 business days — fast enough to clear closing in most cases.

Allen County's geology is a textbook radon environment. The region sits on glacial till over fractured limestone and dolomite bedrock — the exact lithology that produces uranium decay and radon gas migration into building foundations. The Ohio Department of Health's radon map classifies all of Allen County as a Zone 1 (highest potential) area.

We've tested and mitigated homes throughout the area: older brick homes in downtown Lima, mid-century ranches in Elida, newer construction in Shawnee Township and Bath Township, farmhouses in Spencerville and Bluffton, and commercial spaces along the Lima Mall corridor and US-30. We've seen what radon does in this specific soil — and we know which neighborhoods consistently test high.

For real estate professionals: we work regularly with brokerages in Lima, Delphos, and Bluffton, and we know the cadence of an Allen County closing. We coordinate with major local home inspectors, deliver reports formatted for typical Ohio purchase contracts, and communicate directly with listing and buying agents when needed. That's why we're considered the top Radon Testing Allen resource by inspectors who refer radon work.

For school administrators and property managers in Allen East, Bath, Elida, Lima City, Perry, Shawnee, and Spencerville school districts: we're equipped to handle district-wide testing programs with proper documentation for board reporting.

We're one of the only Ohio radon companies that publishes pricing. Here's why: if you have to call to find out what a radon test costs, the company is hoping to convert you on the phone before you compare. We'd rather you compare openly.

• Residential real estate transaction test: flat-rate, all-inclusive, report delivered within hours of pickup
• Homeowner short-term wellness test: same protocol, same pricing tier
• Post-mitigation verification test: discounted rate for verification of existing systems
• Commercial/multi-family/school testing: custom quoted based on building size and monitor count required by protocol
