Radon Mitigation in Grafton, OH — Licensed RC202, EPA-Aligned, Closing-Date Ready

Grafton sits squarely inside Lorain County, an EPA Zone 1 radon area where average indoor levels routinely exceed the 4.0 pCi/L action threshold. The combination of glacial till soils, limestone bedrock fractures, and tight modern construction means many Grafton homes — from older farmhouses near Erie Industrial Parkway to newer builds in the Reserve at Eaton Estates — trap radon at concentrations the EPA classifies as elevated.

Radon Eliminator is a licensed Ohio radon mitigation contractor (Ohio License RC202). We don't sell fans. We install permanent, code-compliant sub-slab depressurization systems and we document the post-mitigation result. When a Grafton inspection report comes back at 6.8 pCi/L and you have fourteen days to close, that license number and that documentation are what move the deal across the finish line.

• Ohio License RC202 — stated upfront, not buried in fine print
• EPA-aligned testing protocols with post-mitigation verification included
• Closing-Date Radon Service — scheduling built around your real-estate deadline
• Multi-vertical experience — single-family, multifamily, apartment complexes, schools, and commercial buildings
• Guaranteed result under 4.0 pCi/L or we adjust the system at no charge

Most Grafton-area radon companies only handle single-family homes and treat closing-date jobs as a nuisance. We productized them. If you're a buyer, seller, agent, inspector, or commercial property owner searching for Radon Mitigation Grafton OH, you're talking to the team that designed its calendar around your timeline.

Every Grafton home and building has a different foundation, soil profile, and HVAC layout. A slab-on-grade ranch off Parsons Road needs a different mitigation design than a 1920s home with a stone-and-mortar basement on Main Street, and both differ from a multi-unit property near Midview Local Schools. Our service catalog is built around that reality.

Sub-slab depressurization is the EPA-recommended standard, and it's what we install in the majority of Grafton homes. A suction point is cut through the slab, sealed, and connected to PVC piping that vents above the roofline through a continuously running radon fan rated for Ohio's freeze conditions. Typical install time: one business day. Typical residential investment in Grafton: $1,295 to $1,895 depending on foundation type, run length, and electrical access.

Ohio HB 264 and federal guidance hold commercial landlords, apartment owners, and school districts responsible for occupant radon exposure. We design multi-point mitigation systems for larger Grafton-area facilities, including schools in the Midview and Keystone districts, multi-unit residential along SR-83, and light-industrial buildings near the Grafton Industrial Park. Engineered drawings, certified post-mitigation testing, and documentation suitable for liability files are included.

If your Grafton purchase agreement has a radon contingency and the clock is running, we move first. Testing in 48 hours. Mitigation install within 3–5 business days of test results. Post-mitigation verification within 24 hours of system activation. All paperwork formatted for the title company and the buyer's lender. This is the service Lorain County agents and home inspectors refer most often.

Plenty of Grafton homes already have a radon system installed by a previous owner or a non-licensed contractor. We diagnose underperforming systems — wrong fan size, undersealed slabs, missing manometers, illegal venting into attics — and bring them to current Ohio code. If your existing system is failing a re-test before resale, this is usually the fastest fix.

Every Radon Eliminator install ends with a continuous radon monitor (CRM) test that documents the result in writing. If the reading isn't under 4.0 pCi/L, we adjust the system until it is. That document is what lenders, buyers, and school boards want to see — and it's the deliverable competitors most often skip.

Our process is engineered for two things: an accurate result and a tight timeline. Here's exactly how a Grafton job runs from first call to verified result.

Step 1 — Phone Diagnostic and Quote (Same Day)

We ask about your test result, foundation type, square footage, and timeline. You get a firm price range and a scheduled install window on that call — not a vague "we'll get back to you."

Step 2 — On-Site Assessment

A licensed RC202 mitigator walks the property, identifies the optimal suction point, plans the pipe route to minimize visual impact, and confirms electrical and venting paths that meet Ohio code.

Step 3 — System Installation (Typically One Day)

We core the slab, seal the foundation, route Schedule 40 PVC, install the radon fan above the conditioned space (per EPA protocol), and mount the U-tube manometer in a visible location. Clean install, clean job site.

Step 4 — Activation and 48-Hour Post-Mitigation Test

We start the fan, then place a continuous radon monitor for a minimum 48-hour test. The result is delivered as a signed PDF — the document buyers, sellers, lenders, and inspectors actually need.

Step 5 — Warranty and Long-Term Monitoring

Systems come with a written workmanship warranty and a fan warranty (typically 5 years). We recommend a re-test every 2 years per EPA guidance, and we keep your file on hand for future closings.

Grafton's geology is the reason radon shows up here. The village sits over the Columbus Limestone formation, which fractures naturally and channels radon gas upward into basements and crawlspaces. Add Ohio's cold-weather "stack effect" — heated homes drawing soil gas in through every slab crack — and you have the exact conditions the EPA calls Zone 1.

We've installed mitigation systems throughout Grafton and the surrounding communities: Eaton Township, LaGrange, Carlisle Township, North Eaton, and into Elyria and Oberlin. We know which neighborhoods sit on shallow bedrock, where the older balloon-frame homes near downtown Grafton tend to leak air, and how the newer subdivisions off Erie Avenue handle radon differently from 1970s ranches on Avon Belden Road.

If you're a Grafton home inspector or real-estate agent looking for a reliable referral partner, ask about our Inspector Partner Program — a published referral structure with priority scheduling for your clients. It's the only program of its kind we're aware of in the Grafton market.

We also serve neighboring Ohio markets including Cleveland, Canton, and Columbus, with the same RC202 license and the same closing-date discipline.

We publish ranges because real-estate clients are sick of vague answers. Final price depends on foundation type, slab condition, and pipe routing, but here's what Grafton homeowners typically pay:

• Standard residential mitigation (basement or slab): $1,295 – $1,895
• Crawlspace encapsulation + mitigation: $1,895 – $2,995
• Multi-suction-point systems (large or complex homes): $2,295 – $3,495
• Existing system upgrade or fan replacement: $395 – $895
• Post-mitigation testing (included with install): $0
• Commercial / multifamily / school systems: Custom-quoted

Financing is available for qualifying projects. We accept all major cards, and we can invoice through a title company at closing for real-estate transactions.
