How Gelco Products Fail - and How We Fix Them

• Multi-flue cap frame fatigue on the Gelco Series C. The C-series uses a lighter-gauge stainless frame that flexes more than single-flue designs. After five to seven Los Angeles winters, the crossbars fatigue at the weld points, especially on south-facing chimneys in Pasadena and Altadena where thermal cycling is sharpest. We spot the hairline cracks during our level-2 camera inspection, then either re-weld with 304 stainless rod or source a Series C replacement frame from our Gelco supplier in Burbank.
• Mesh corrosion in coastal zones. The standard 5/8-inch spark arrestor mesh on Gelco caps is 304 stainless, but within three miles of the Pacific in Santa Monica or San Pedro, salt air pits the mesh from the inside out. Homeowners smell smoke on mild days because the clogged mesh chokes draft. We swap to 316 marine-grade mesh, which Gelco offers but rarely stocks locally. Costs a bit more. Lasts twice as long.
• Crown separation on Gelco top-mount installations. When a Gelco cap is mounted to a deteriorated crown rather than the flue tile itself, the crown’s own cracks telegraph upward and loosen the cap. We see this constantly in 1960s ranch houses in the San Fernando Valley where original crowns were poured thin. Our fix: crown repair or pour first, cap second. No exceptions. A cap on a bad crown is a band-aid.
• Storm collar gasket hardening. Gelco’s factory EPDM gasket on adjustable storm collars turns brittle after eight to ten years in Los Angeles sun. The gap opens, water runs the flue, and you get efflorescence in the firebox. It’s a $12 part and twenty minutes to replace, but most sweeps miss it because they’re looking at soot, not rubber. We check it every time.
• Custom cap anchor pull-out on stucco chimneys. The Gelco custom line uses expansion anchors that grip poorly in soft, decades-old stucco common in Los Angeles hillside homes. We’ve found caps held by two of six anchors, the rest spun free. We switch to toggle bolts with stainless sleeves, set into the masonry behind the stucco. Done right, and we stand behind it.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your Gelco model if you know it, and books a window that works. No app, no callback tag.
2. 2
   Level-2 camera inspection. Our technician photographs the cap, crown, flue condition, and any water damage. You see the images. We give you a plain-English verdict on what’s actually failed and why.
3. 3
   Parts decision. If your Gelco part is available OEM and the price makes sense, we order it. If lead time is three weeks or the OEM price is out of line, we source a quality aftermarket equivalent that matches spec. You decide. No pressure.
4. 4
   The repair. Background-checked, uniformed tech, most jobs done in one visit. Crown work cures overnight when needed; we schedule the cap mount for day two and show up when we say.
5. 5
   Post-repair test. We run a draft test and water-simulate with a controlled spray. No leaks, no draft drop, no departure.
6. 6
   Documentation and guarantee. Photos, invoice, and the 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing.
