How Gelco Products Fail - and How We Fix Them

Gelco makes a solid product, but every liner brand has its weak points. Here’s what we actually see in Sterling chimneys.

• Gelco stainless steel flexible liners develop pinhole leaks at the corrugation valleys. This is the most common Gelco failure we find in Sterling. The thin-walled 316Ti alloy handles heat well but flexes with thermal cycling, and over years the low points between corrugations can thin and perforate. You’ll notice a faint sulfur smell in the house or white staining on the chimney exterior. The fix is a full liner replacement, not a patch. We pull the old Gelco liner, inspect the flue cavity, and install a new liner sized to your appliance, not just whatever fits.
• Gelco pre-insulated liners lose their insulation wrap where the liner passes through the smoke shelf. The wrap gets snagged during installation or degrades from years of expansion and contraction. Once the insulation is compromised, flue gases cool too quickly, creosote condenses faster, and you get a drafting problem that worsens each season. We strip the old insulation, assess whether the liner itself is still sound, and either re-wrap or replace depending on liner wall thickness.
• Gelco’s connection bands and top plates are often the first thing to go, not the liner itself. We see this constantly. The liner can be fine, but the stainless connection band at the appliance outlet has corroded or loosened, letting flue gas seep into the chase or house. This is a repair we can often do without pulling the whole liner. If the band is Gelco-specific, we match it; if the original was undersized or improvised, we correct that too.
• Gelco rigid liners in masonry chimneys shift at the joints when the surrounding brick moves. Sterling’s freeze-thaw cycles are hard on older brick, and when the chimney settles or spalls, rigid Gelco sections can separate at the seams. You’ll see soot streaks on the exterior wall near the roofline or smell smoke when the fireplace isn’t in use. We inspect the liner joints with a camera, and if the liner has separated, we either re-seat the sections or go to a flexible liner that tolerates the movement better.
• Gelco liners installed by the previous owner sometimes weren’t sized for the actual appliance. This isn’t a Gelco defect, it’s an installation error, but it’s one we correct regularly. An oversized liner lets flue gas linger and condense; an undersized one chokes the draft. We measure the appliance BTU output and the flue dimensions and tell homeowners if the liner was wrong from day one. Then we fix it with the right size.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   We put eyes on it. Wendell or one of his crew comes out, runs a camera up the flue, and looks at the liner, the connection points, the crown, and the brickwork. You see the footage. No guessing, no vague verdicts.
2. 2
   Plain-English diagnosis. We tell you what’s failing, what caused it, and whether it’s a repair or a replacement. If the liner is fine and the problem is elsewhere, we say so. We don’t sell liner jobs that don’t need doing.
3. 3
   Parts decision. If Gelco OEM parts are available and make sense, we use them. If a quality aftermarket liner from DuraFlex or HeatShield fits your chimney better for less money, we tell you that too. You decide with the facts in front of you.
4. 4
   The work. We remove the old liner, prep the flue, and install the new liner properly sized, properly insulated, properly connected. For partial rebuilds, we replace only the damaged brick and mortar, not the whole chimney just because it’s easier to quote.
5. 5
   Test and verify. We run the appliance, check the draft, and camera the finished job. You see the result before we leave.
6. 6
   90-Day Done Right Promise, in writing. If something isn’t right, one call brings us back. That’s the whole guarantee, and every job gets it on paper.
