Radon Testing in Grafton OH is not a formality — Lorain County sits on glacial till and shale-rich soils that consistently produce some of the highest radon readings in Ohio. The Ohio Department of Health classifies Lorain County as Zone 1, meaning the average indoor radon level exceeds the EPA action threshold of 4.0 pCi/L. If you live, sell, or manage property in Grafton, testing is not optional — it is the only way to know what you and your tenants or buyers are breathing.

Radon Eliminator is a licensed Ohio radon contractor (Ohio Mitigation License RC202) serving Grafton, Eaton Township, LaGrange, Carlisle Township, and the surrounding Route 83 corridor. We test residential homes, commercial buildings, apartment complexes, and schools using EPA-aligned protocols — and we deliver lab-grade results fast enough to meet a real-estate closing deadline.

Call (440) 360-1370 for same-week scheduling, or request a Grafton radon test online. No call-for-pricing games. No upsell pressure. Just a licensed pro, a calibrated monitor, and a written report you can hand to your agent, your buyer, or your attorney.

Most Grafton homeowners discover radon the hard way: an inspector flags it three weeks before closing, and suddenly a $300,000 transaction is hanging on a 48-hour test result. That is the exact scenario we were built to solve. Here is why agents, inspectors, and homeowners across Lorain County call us first.

• Licensed Ohio Specialist (RC202) — We are not an HVAC company that dabbles in radon. Radon testing and mitigation is the only work we do, and we hold the Ohio Department of Health mitigation license to prove it.
• Closing-Deadline Speed — Our "we won't blow up your closing" promise: most Grafton tests are deployed within 48 hours of your call, with results in your inbox within 48–96 hours of deployment.
• Transparent, Published Pricing — Residential real-estate radon tests in Grafton start at a flat, published rate. You will know the cost before we hang up the phone.
• EPA-Aligned Protocols — Continuous radon monitors (CRMs) calibrated annually, deployed per AARST-NRPP standards, with closed-house conditions documented.
• Multi-Vertical Expertise — Residential, commercial, school, and multi-family compliance testing. Few contractors in the Grafton area can legally and operationally handle a 24-unit apartment building. We do.
• Home Inspector Referral Program — A named partnership for Grafton-area inspectors with priority scheduling and a referral structure that respects the relationship.

Every property type comes with its own protocol. Below is exactly what we test, how we test it, and who it serves.

The standard EPA-aligned short-term test using a continuous radon monitor placed in the lowest livable level of the home. Closed-house conditions are required for 12 hours before and during the 48-hour test window. You receive a digital PDF report with hourly readings, the average pCi/L, temperature, humidity, and tamper data — formatted to satisfy buyers, lenders, and Ohio real-estate attorneys.

After any radon mitigation system is installed — by us or another contractor — we perform an independent 48-hour verification test to confirm the system has brought levels below 4.0 pCi/L. This is increasingly required by Ohio lenders and savvy buyers before final walkthrough.

For homeowners not under a transaction timeline, a 90-day alpha-track test produces a more accurate picture of year-round radon exposure. Grafton's freeze-thaw cycles and basement use patterns make seasonal variation significant — a winter average can easily double a summer reading.

For Grafton apartment owners, the Midview Local Schools district, and commercial property managers along SR-57, we provide AARST-MAMF and AARST-MALB compliant testing. This includes building diagnostics, device placement maps, occupant notification documentation, and a deliverable suitable for HUD, insurance carriers, or the Ohio Department of Health.

Grafton-area home inspectors can add radon to any inspection through our partner program. We bring our own devices, our own license, and our own report — so the inspector stays in their lane and the client gets a defensible result. Ask about our named Special Offer for active inspector partners.

A radon test is only as accurate as the protocol behind it. Here is exactly what happens when you book the best Radon Testing Grafton has available.

Call (440) 360-1370 and a licensed technician — not a call center — confirms the property type, the closing date if applicable, and a deployment window. Real-estate transactions get priority scheduling.

We arrive at your Grafton property, place a calibrated continuous radon monitor in the lowest livable level (typically the basement or first floor for slab homes), document closed-house conditions, and photograph the placement for chain-of-custody integrity.

The monitor records hourly radon, temperature, humidity, and barometric pressure. Tamper sensors flag any door openings or device movement — protecting the integrity of the test if a seller is incentivized to manipulate conditions.

Within 24 hours of pickup, you receive a digital report with the average pCi/L, hourly graph, environmental data, and a clear interpretation: pass (<4.0 pCi/L), borderline (2.0–3.9 pCi/L), or action required (≥4.0 pCi/L).

If levels exceed 4.0 pCi/L, you get a written, flat-rate mitigation quote the same day — and we can typically install a code-compliant sub-slab depressurization system within 5–7 business days, well inside most Grafton closing windows. Learn more about our radon mitigation systems.

Grafton sits in a high-radon corridor that runs through Lorain, Medina, and Cuyahoga counties. The combination of glacial deposits, Ohio Shale bedrock, and the prevalence of full basements in homes built along Main Street, in Reserve at Eaton, and throughout the older neighborhoods near Grafton Village means radon entry points are common — gravel sumps, block-wall basements, dirt crawlspaces, and cold-joint slab penetrations.

We have tested homes from the historic streets near the Grafton Library and Grafton Village Park to newer construction off Parsons Road and SR-83. We've worked with property managers near Midview High School and provided compliance testing for commercial buildings near the Grafton Correctional Institution corridor. We know what Grafton soil produces, what Grafton basements look like, and which construction eras tend to produce the highest readings.

That local familiarity matters. A radon contractor flying in from Columbus or Cleveland doesn't know that homes built between 1955–1975 along Erie Street tend to have unsealed block walls that act like a chimney for soil gas. We do. That's the difference between top Radon Testing Grafton OH professional service and a generic national franchise.

We also serve nearby communities including Elyria, North Ridgeville, LaGrange, Wellington, Oberlin, Avon, and Columbia Station. If you searched "Radon Testing near me" or "Radon Testing Grafton near me," you're in our primary service zone.

We publish our pricing because Grafton homeowners and agents are tired of "call for a quote" runarounds. Affordable Radon Testing Grafton residents trust starts here:

• Residential Real-Estate Radon Test (48-hour CRM): Flat-rate, published on our booking page. Includes deployment, retrieval, and digital report.
• Post-Mitigation Verification Test: Discounted rate when paired with our mitigation work; standard rate for independent verification of third-party systems.
• Long-Term Alpha-Track Test: Lower per-device cost, ideal for owner-occupied homes not in transaction.
• Commercial / Multi-Family / School Testing: Quoted per square footage and device count per AARST protocols. Free site-walk for buildings over 10,000 sq ft.

No hidden fees. No travel charge inside Lorain County. No upsell on the call.
