Aid sits in Lawrence County in the rolling hills of southern Ohio — and that geography matters. The uranium-bearing shales and clay soils common across southeastern Ohio release radon gas as they break down. That gas seeps through foundation cracks, sump pits, and crawlspace vents into the homes above. The Ohio Department of Health reports that more than 1 in 3 Ohio homes test above the EPA action level of 4.0 pCi/L, and Lawrence County properties frequently test higher.

If you searched for Radon Testing Aid OH, you're probably in one of three situations: your home inspector flagged elevated radon mid-transaction, you read that radon is the #1 cause of lung cancer in non-smokers, or your real estate agent told you the buyer is requiring a test before closing. Radon Eliminator handles all three — and we do it on your timeline, not ours.

We are Ohio's licensed radon authority (Ohio Mitigation License RC202). We don't sell HVAC, we don't waterproof basements, and we don't 'also do radon' on the side. Radon testing and mitigation is the only thing we do — and we do it across residential, commercial, school, and apartment properties statewide.

There are plenty of companies that will stick a charcoal canister in your basement. There are very few licensed Ohio radon professionals who will stand behind the result in a contested real estate transaction, a commercial compliance audit, or a school board meeting. Here's what separates the best Radon Testing Aid homeowners and agents trust:

• Ohio License RC202 — Posted on every report, every invoice, every truck. Most competitors won't even list a license number on their website.
• 48-hour closing-deadline turnaround — We won't blow up your closing. Tell us your closing date and we'll schedule around it.
• EPA-aligned protocols — Continuous radon monitors (CRMs) and AARST-NRPP testing standards on every job, not consumer-grade kits.
• Transparent flat-rate pricing — Residential short-term tests start at clearly published rates. No 'call for a quote' games.
• Multi-vertical expertise — Single-family homes, apartment complexes, commercial buildings, and K-12 schools. The compliance-grade work most local guys can't legally handle.
• Home inspector referral program — A named special offer for licensed Ohio inspectors who refer clients to us.

When a deal is on the line, you want a professional Radon Testing Aid OH provider whose name your title company already recognizes. That's us.

Every property, every transaction, and every compliance requirement is different. Radon Eliminator offers a full menu of Radon Testing services Aid OH property owners and professionals rely on:

The most common request we get in Aid. A buyer's agent has required a radon test as part of inspection contingencies, and you need a defensible result before the financing window closes. We deploy a continuous radon monitor for a minimum 48-hour closed-house test, then deliver a signed, RC202-stamped report by email — typically within 24 hours of pickup. If results are above 4.0 pCi/L, we can quote mitigation the same day so the deal stays alive.

For Aid homeowners who aren't in a transaction but want the most accurate picture of year-round exposure, we offer long-term alpha-track testing. Radon levels fluctuate with weather, soil moisture, and HVAC use. A 90-day test averages those swings and gives a far more reliable annual exposure number — important if you have children sleeping in finished basement bedrooms.

If you own an apartment complex, office building, daycare, or assisted living facility in or near Aid, you have legal exposure. HUD requires radon testing on most multifamily acquisitions. Ohio licensure rules require commercial tests be performed by a licensed mitigation professional like Radon Eliminator. We follow ANSI/AARST MAMF and MALB protocols — the standards lenders, insurers, and attorneys actually recognize.

Ohio school districts increasingly require radon testing in occupied ground-contact classrooms. We provide ANSI/AARST MA-MFLB-2014 compliant testing programs, including device placement maps, chain-of-custody documentation, and board-ready reporting. Whether you're testing a single building or a full K-12 district, we scale.

After any radon mitigation system is installed — by us or another contractor — a verification test confirms the system actually dropped radon below 4.0 pCi/L. We provide independent post-mitigation testing for buyers who need third-party confirmation before signing.

We've streamlined radon testing in Aid down to a process that respects your timeline and produces results that hold up under legal and lender scrutiny.

Call our Aid line or submit the form on this page. We confirm your address, the reason for the test (transaction, peace of mind, compliance), and your deadline. Most real estate tests are deployed within 24-48 hours of the initial call.

A licensed RC202 technician places an EPA-aligned continuous radon monitor in the lowest livable level of the home, follows closed-house conditions per AARST protocol, and documents tamper-evident placement. We do not use mail-in canisters for real estate work — they're too easy to challenge.

The monitor samples hourly for a minimum of 48 hours. Windows and exterior doors stay closed except for normal entry/exit. The CRM logs temperature, humidity, and barometric pressure — data that prevents disputes about whether the test was 'gamed.'

We retrieve the monitor and deliver a signed, RC202-stamped PDF report by email — typically within 24 hours. The report includes the average pCi/L reading, hourly trend chart, environmental conditions, and clear next-step guidance. If results require mitigation, we can quote it the same day.

Aid is a small unincorporated community in Symmes Township, Lawrence County — surrounded by hills, hollows, and the kind of clay-heavy soils that make southern Ohio a high-radon zone. Our technicians regularly test homes throughout the area: along State Route 141, near Lake Vesuvius and the Wayne National Forest, and across into Ironton, Pedro, Waterloo, and Willow Wood. We also serve nearby communities including Oak Hill, Jackson, Gallipolis, and the broader Tri-State region around Huntington and Ashland.

Homes in this region have specific risk factors we test for differently than a slab-on-grade ranch in central Ohio: walkout basements cut into hillsides, older block foundations with mortar joints, and crawlspaces over exposed soil. We adjust monitor placement and closed-house instructions accordingly. That local fluency is part of why agents in Lawrence and Gallia counties keep us on speed dial — we're the top Radon Testing Aid OH option because we actually understand the housing stock.

Searching for Radon Testing near me or Radon Testing Aid near me? We dispatch from our regional service footprint and treat southern Ohio as a priority service area, not an afterthought.

Most of our competitors make you call for a price. We don't. Affordable Radon Testing Aid homeowners and agents deserve to know what they're paying before they pick up the phone. Residential real-estate short-term tests are flat-rate, with discounts for tests bundled with a same-week mitigation quote. Commercial, multifamily, and school testing is priced per device and per building based on AARST protocols — we'll quote it in writing within one business day.

We don't upsell tests you don't need. If a long-term test makes more sense than a short-term test for your situation, we'll tell you. If your inspector already provided a passing test and you don't need a re-test, we'll tell you that too.
