How Gelco Products Fail - and How We Fix Them

• Multi-Flue Caps (Model 13245 series): The expanded metal mesh on these wide-span caps fatigues at the weld points after seven to ten years of Carroll County freeze-thaw cycles. We’ve replaced dozens on Westminster homes near Main Street where the mesh has separated from the frame, letting squirrels and starlings nest directly on the flue tile. We fit a new Gelco-spec cap with heavier-gauge mesh or a stainless aftermarket equivalent, depending on your flue configuration.
• Single-Flue Stainless Caps (Model 17502 and 17504): The set-screw collar loosens as the flue liner expands and contracts through burning season. In Westminster’s older homes with unlined clay flues, this collar slips entirely, tilting the cap and creating a gap that funnels rain onto the crown. We reseat with a proper Gelco-compatible base plate or upsize to a slip-fit model that accounts for thermal movement.
• Crown Coat failures on Gelco-protected chimneys: Homeowners sometimes assume the cap protects the crown completely. It doesn’t. Water still tracks down the flue wall, and Gelco’s standard cap overhang isn’t wide enough to shed driving rain on chimneys shorter than three feet above the ridge. We see this on ranch-style homes in the Westminster watershed. We repair the crown with a proper cementitious slurry, then verify cap overhang is adequate or recommend a wider model.
• Galvanized Cap Rust-through (Pre-2015 Models 13240 and 13242): Gelco switched to stainless as standard around 2015, but plenty of galvanized caps are still up on Westminster chimneys. The salt in our winter road runoff accelerates corrosion at the drip edge. We replace with 304 stainless or copper Gelco equivalents, never reinstalling galvanized on any chimney we touch.
• Custom Cap Wind Uplift (Model C-200 series): These larger custom jobs use lighter-gauge skirt metal to keep shipping cost down. On exposed Westminster lots, especially north of town toward Manchester, we’ve seen skirt tabs fatigue and rattle. We reinforce with stainless strapping or spec a heavier custom build from Copperfield if the flue arrangement demands it.

4. 4
   The repair. Cap jobs: remove old unit, inspect flue tile, install new cap with proper clearances, secure against wind uplift. Crown jobs: grind out loose material, apply bonding agent, trowel new crown mix to proper slope and overhang, seal with vapor-permeable coating.
