Radon Testing in Amherst OH is not a side service for us — it is the entire business. Radon Eliminator holds Ohio Mitigation License RC202, and we test residential, commercial, school, and apartment properties across Amherst, South Amherst, Vermilion, Elyria, and the rest of Lorain County every single week. Our equipment is calibrated to EPA protocols, our reports satisfy lender and Ohio Department of Health requirements, and our turnaround is built around real estate closings — not contractor convenience.

Lorain County sits inside one of the highest-radon regions in the United States. The EPA classifies most of northern Ohio as Zone 1, meaning the predicted average indoor radon level exceeds 4.0 pCi/L — the action threshold at which the EPA recommends mitigation. Homes built on the glacial till and shale formations under Amherst routinely test between 4 and 15 pCi/L, and we have measured Amherst basements above 30 pCi/L. If you have not tested, you do not know. And if your inspector flagged a number above 4.0 mid-transaction, you need a licensed pro now — not next week.

Call (440) 332-3722 to schedule a test, or request a written quote online. Most Amherst tests are deployed within 24–48 hours of your call.

Most local outfits offering radon testing are HVAC contractors, basement waterproofers, or general home inspectors who add radon as a sideline. We are different — and the difference matters when a closing is on the line.

• Ohio License RC202. A state-issued radon mitigation license, not a general contractor card. Verify it on the Ohio Department of Health registry.
• Closing-deadline guarantee. If your purchase contract has a radon contingency, we work backward from your closing date. Test deployed within 24–48 hours, results within 48 hours of pickup, and mitigation installed in 1–2 days when needed.
• EPA-aligned continuous radon monitors (CRMs). Hour-by-hour data, tamper detection, and a signed report — not a cheap charcoal canister mailed to a lab.
• Transparent flat-rate pricing. Standard residential radon tests in Amherst are $150. Multifamily, commercial, and school testing is quoted per measurement point — no surprise invoices.
• Multi-vertical depth. We are one of the few Ohio firms equipped to handle compliance-grade testing for apartment complexes, schools, and commercial buildings under ANSI/AARST MAMF and MA-MFLB protocols.
• Home inspector referral program. Inspectors across Amherst, Avon, and North Ridgeville refer to us because we never blow up their client's deal — and we have a dedicated Special Offer for referred transactions.

Not all radon tests are equal. The cheap kits at the hardware store are passive, slow, and easy to tamper with. Our professional radon testing in Amherst OH is built for evidence that holds up to lenders, attorneys, and the Ohio Department of Health.

The flagship service. A calibrated continuous radon monitor is deployed in the lowest livable level of the Amherst property for a minimum of 48 hours under closed-house conditions. You receive a sealed, signed PDF report with hourly readings, average pCi/L, and a pass/fail recommendation referenced to the EPA 4.0 pCi/L action level. Reports are accepted by every Ohio lender we have ever worked with.

For Amherst homeowners who are not under a transaction deadline, we offer 90-day and annual alpha-track testing for a more accurate picture of year-round exposure. Radon levels fluctuate seasonally — winter readings in Ohio are typically the highest because of stack effect and closed windows. This is the right test if you want to know what your family is actually breathing.

After any radon mitigation system is installed — by us or anyone else — a follow-up test must confirm the system actually dropped the level below 4.0 pCi/L. We perform independent verification testing and provide documentation suitable for closing files and warranty records.

Ohio law and ANSI/AARST standards require multi-point testing for commercial and multifamily properties — typically 10% of ground-contact units, every floor of schools, and specific configurations for daycare and assisted-living facilities. We design the measurement plan, deploy enough monitors to do it legally, and deliver a compliance report property owners can file with regulators or insurers.

If your test comes back high, we are already licensed to design and install the fix. Our active soil depressurization systems are code-compliant under ANSI/AARST SGM-SF-2017 and built with lifetime-grade workmanship. Most Amherst systems are installed for $1,200–$1,800 in 1–2 days. See our radon mitigation page for full details.

Speed matters, but only if the result is defensible. Here is exactly how a Radon Eliminator test runs from the moment you call.

Call (440) 332-3722 or submit the online form. We confirm the property address in Amherst, your closing date if applicable, and the lowest livable level where the monitor will sit. Standard scheduling is 24–48 hours; emergency real estate scheduling is often same-day.

Before deployment, the home must be in closed-house conditions for at least 12 hours — windows and exterior doors closed except for normal entry/exit. We walk you or the listing agent through the protocol so the test is valid the first time.

A calibrated continuous radon monitor is placed 2–6 feet off the floor, away from exterior walls, drafts, and HVAC supplies. The unit records hourly pCi/L readings, temperature, humidity, and motion — so any tampering or open-window event is documented.

After 48 hours minimum, we retrieve the monitor and generate a signed PDF report within 24 hours. The report shows the average pCi/L, hourly data graph, EPA action level reference, and clear next-step recommendations. Reports go to you, your agent, and your lender if you authorize it.

If your Amherst home reads at or above 4.0 pCi/L, we hand you a written mitigation quote on the spot — no callbacks, no estimator visits, no games. Most systems are installed within 5–7 business days, faster for transactions.

Amherst sits on the Berea Sandstone — the same formation that gave the town its 'Sandstone Capital of the World' nickname and powered the historic quarries off Park Avenue. That geology is beautiful for architecture and brutal for radon. Sandstone, shale, and the glacial till layered above them are natural sources of uranium decay, which produces radon gas that migrates up through soil and into basement slabs, sump pits, and crawlspaces.

We see consistently elevated readings in:

• Older homes near downtown Amherst along Park Avenue, Cleveland Avenue, and Tenney Avenue — typically pre-1970 builds with block foundations and dirt-floor or partially finished basements.
• Newer subdivisions south of SR-113 and out toward Quarry Road — tight, energy-efficient construction concentrates radon if there's no passive vent stack.
• South Amherst village homes built directly over old quarry fill.
• Commercial and school buildings in the Amherst Exempted Village School District — slab-on-grade construction with mechanical ventilation can mask elevated radon for years.

We also serve surrounding communities including Elyria, Lorain, Avon, Avon Lake, North Ridgeville, Vermilion, Oberlin, and Sheffield Lake. If you are a Lorain County home inspector or real estate agent who wants to add us to your preferred-vendor list, ask about our referral program when you call.
