How Gelco Products Fail – and How We Fix Them

• Gelco cast-in-place liner spalling at the flue crown: When Atlanta’s heavy spring rains and freeze-thaw cycles in winter hit the crown of a chimney with a Gelco liner, moisture seeps into the concrete crown and breaks it apart from the inside. Spalling (that’s the brick or concrete surface flaking off in chunks) around the flue opening is the first sign. We rebuild the crown with a proper overhang and drip edge, then seal the crown with a breathable waterproofing compound so the Gelco liner isn’t fighting water intrusion.
• Gelco liner joint separation at elbow transitions: On braced and offset chimneys around Midtown and Decatur, older Gelco installations sometimes show joint separation where the liner bends through the smoke chamber. The symptom is usually a smell of smoke in an upstairs room, even when you don’t have a fire going. The liner shifts due to thermal expansion and contraction, and the connection points pull apart. We open the thimble, inspect that transition with a camera, and re-secure those joints with high-temp refractory cement rated for Gelco’s tolerances.
• Gelco top plate and cap failure from corrosion: The top plate isn’t the cap. The top plate is the stainless steel plate that sits on top of the flue tile, and the cap sits above it. On older Gelco installs in homes around Grant Park and East Atlanta, we see top plates rusted through from all that airborne moisture, which lets water run straight down the outside of the liner. The fix is a correctly-sized stainless steel top plate and a properly bracketed cap, not a bucket of silicone.
• Creosote adhesion inside Gelco liners from low-temp burns: Cast-in-place liners tend to hold heat differently than rigid stainless liners, and in Atlanta’s damp shoulder season (October to November), a homeowner burning slightly green wood doesn’t get the high flue temps needed to burn off the residue. The result is a glaze of creosote building up faster than it should on the liner wall. We remove it with aggressive brushing and dry chemical treatment, then teach you exactly what to burn to keep that flue clear.
• Mortar joint deterioration around Gelco throat connections: The throat of a chimney is where the liner transitions through the smoke chamber. Because Gelco systems rely on that cast-in-place bonding material to create a smooth path, any cracking in the throat area creates eddies of flue gas that cool and deposit creosote unevenly. We see this a lot in homes built in the 80s and 90s around Sandy Springs and Roswell. We refill those throat joints with temperature-rated mortar and then verify the draft with a smoke test before we call it done.

Our Gelco Chimney Repair Process

When you call (762) 320-6525, here’s what a Gelco repair with us actually looks like:

1. 1
   Book the visit. A real person answers, gets your address, and tells you exactly who’s coming, in what tracked window, not a four-hour guess.
2. 2
   Camera inspection first. Your technician runs a camera through the flue and shows you the images on-site. I’d rather show you a photo of the problem than talk around it. If your Gelco liner is fine and the issue is elsewhere, we’ll tell you that.
3. 3
   Written diagnostic and price. You get a written price before any tool touches your chimney. No “found something else once we were up there.”
4. 4
   The repair. OEM Gelco parts when available, but we’re honest when a quality aftermarket component like a DuraFlex cap or HeatShield compound is equally durable and faster to source in Atlanta.
5. 5
   After-photos and testing. We document everything with before-and-after photos and run a draft or moisture check before we leave.
6. 6
   Written guarantee. Every repair comes with a 365-Day Done Right Promise. If the repair fails within that time, we come back and make it right, free.

Why Atlanta Homeowners Call Hadley Chimney Atlanta for Gelco Work

We’ve inspected and repaired chimneys across Atlanta for years, from older Craftsman bungalows in Grant Park to newer builds up toward Marietta, and Gelco systems come up often because they were so widely installed in the 80s and 90s. Cory Mitchell, our owner, trained in construction and HVAC at Los Angeles Trade-Technical College, and he and the crew know exactly where Gelco installs tend to fail in Atlanta’s specific climate. We also work with DuraFlex and HeatShield components on a regular basis, which means when a Gelco part isn’t the right choice anymore, we can recommend and install a proven alternative. Every job includes live arrival tracking, before-and-after photos, and digital invoicing through the Relay Visibility Guarantee. Background-checked, uniformed technicians. A written price before any work starts. And a 365-Day Done Right Promise on every repair, with a free second visit if it fails. That’s the deal, plain and simple.
