How Gelco Products Fail - and How We Fix Them

Gelco makes a solid liner system. But every liner brand has its own failure patterns, and after years inside Reading chimneys, we’ve learned which ones show up on Gelco jobs.

• Flexible liner kinking at the smoke-shelf offset. We see this most often with the Gelco Flex SS series in older Reading rowhouse chimneys where flues jog at the smoke shelf. The liner gets pulled too tight through the bend, kinks, and restricts draft. Homeowners notice the fireplace suddenly smokes back into the room after never having that problem before. The fix is pulling the liner, correcting the bend geometry, and re-running it with proper standoffs. Kinked liners can’t be un-kinked in place, no matter what you read online.
• Stainless liner corrosion from acid condensation. Reading’s cold winters mean long, slow burns in older stoves and inserts. That produces low flue gas temperatures and acidic condensation that sits inside the liner. Gelco’s stainless holds up as well as any brand, but after 12 to 15 years of those conditions, pinholes develop in the inner wall. The symptom is a faint metallic smell around the fireplace in damp weather or tiny rust streaks on the liner cap. We scope it, show you the footage, and replace the liner with the right alloy for your appliance. No tear-out, no upselling downspout fixes that won’t matter.
• Liner-cap seam separation on exposed chimney tops. Gelco’s caps are fine equipment, but on Reading chimneys that take the full brunt of nor’easter rain and freeze-thaw cycles, the riveted seam between cap and liner can work loose. Water then tracks down the outside of the liner inside the old flue, and you never see it until the damper rusts or the firebox gets damp. We re-rivet and seal the seam, inspect the chase or flue interior, and tell you honestly if the cap just needs replacing instead of rebuilding.
• Improper liner sizing from the original install. This isn’t a Gelco manufacturing problem. It’s a reason we get called after another company did the work. A 6-inch liner jammed onto a stove that drafts properly with an 8-inch flue starves the appliance, builds creosote fast, and shortens liner life. We see it in Reading homes where inserts were added in the early 2000s. We recalculate based on appliance BTU and flue height, then install the correctly sized Gelco liner. The old one goes to the scrap pile.
• Masonry failure above the liner crown. The liner itself may be fine, but the brick above it sags or the crown cracks wide. That lets water behind the brick, which freezes, expands, and pops the mortar joints open every winter. We rebuild from the roofline up or do a partial rebuild where needed, bed the new liner crown properly, and cap it. Reading chimneys, especially those facing west toward the river, take this punishment every year.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   You call (484) 209-0837. A live person answers. You describe what you’re seeing, and we give you a rough price range and honest expectations before we ever roll a truck.
2. 2
   We inspect and camera-scope the flue. Every Gelco liner job starts with a camera. You see the footage. If the liner doesn’t need work, Wendell or his crew will tell you that plainly and shake your hand.
3. 3
   We decide the parts. For Gelco liners under warranty, we use proper Gelco components and follow their install specs so you don’t void coverage. For out-of-warranty work, we may recommend quality aftermarket stainless that costs less and carries the same practical lifespan. We’ll show you both numbers and let you choose.
4. 4
   The liner or rebuild goes in. We remove the old liner or demo the bad masonry, install the new liner with proper clearance and insulation where needed, rebuild what needs rebuilding, and seal every joint correctly.
5. 5
   We test draft and smoke behavior. The liner doesn’t pass until the draft is right and the smoke path is clean. Camera footage again, so you can see what we see.
6. 6
   You get the 90-Day Done Right Promise in writing. If something’s not right, one call brings us back at no additional cost. That’s the whole point.
