How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue chimney caps: The 304 stainless mesh on these caps holds up well to salt air near the coast, but in the San Fernando Valley and Pasadena foothills, we see the welded corner seams crack from thermal cycling - 90-degree days dropping to 50-degree nights, repeated thousands of times. We re-weld with 316L filler rod or source a matching Gelco replacement cap rather than forcing a generic fit.
• Gelco Single-Flue caps with screw-in legs: The leg brackets fatigue where they meet the flue tile, especially on older Los Angeles homes with 9×13 or 13×13 flues from the 1960s. We find stripped threads or cracked flue corners in about one of every three inspections. Our fix: either a Gelco leg-replacement kit with deeper-set anchors, or a custom base plate if the flue itself is compromised.
• Gelco Lyemance and Lock-Top top-sealing dampers: The silicone rubber gasket hardens after 8-12 years in L.A.’s UV exposure, losing its seal and letting conditioned air escape. The cast-aluminum frame can also warp if the chimney ever had a chimney fire the owner didn’t know about. We carry replacement gaskets and spring assemblies, but if the frame is warped, we replace the whole damper with a new Gelco unit - aftermarket dampers rarely match the throat dimensions of these older systems.
• Gelco stainless steel chimney liners: The 316Ti alloy resists creosote corrosion, but we’ve seen premature failure where the liner was sized wrong for a converted fireplace - too large a diameter creates lazy draft, condensation pools at the low spots, and the liner corrodes from the inside out. We verify the NFPA 211 sizing chart against the appliance BTU rating, then install a correctly sized Gelco liner or, if the appliance has changed, a DuraFlex or HeatShield alternative that matches the new load.
• Gelco chase covers on prefab chimneys: The galvanized steel versions rust at the drip edge first, particularly where L.A.’s rare but heavy winter rains sit against the chimney shoulder. We replace with Gelco’s stainless chase cover or, if the chase itself has settled from foundation movement common in the Mid-Wilshire and Silver Lake areas, we rebuild the chase framing and install a new cover with an expanded drip edge.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, day or night. We ask for the Gelco model name or series if you know it, and we book a two-hour arrival window.
2. 2
   Level-2 camera inspection. Our technician runs a camera the full length of the flue and photographs every Gelco component - cap, damper, liner connection, crown condition. You see the images on a tablet while we explain what we’re looking at.
3. 3
   Plain-English verdict and parts decision. We identify whether your repair needs genuine Gelco parts, a quality aftermarket equivalent, or a compatible component from our DuraFlex or HeatShield inventory. We explain the trade-off for each - warranty coverage, longevity, cost - and you decide.
4. 4
   Upfront pricing and signature. The estimate is the invoice. No add-ons discovered mid-job unless we both agree to a change order.
5. 5
   The repair and live test. We complete most Gelco repairs in one visit. For dampers, we cycle the mechanism 20 times and verify seal with a smoke pencil. For liners, we run a draft test at operating temperature. For masonry, we mist-test the repointed joints.
6. 6
   Documentation and guarantee. You get photos, the written verdict, and our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
