How Gelco Products Fail - and How We Fix Them

Gelco makes a solid cap. But Long Island weather has a way of finding the weak points. Here’s what we actually see on roofs from Levittown out to the North Shore:

• Gelco stainless steel caps with rust at the screen crimp. Gelco’s standard stainless caps hold up well, but the screen attachment points are the first place salt air and winter road spray bite. We see pinholes there long before the lid gives out. Fix: replace with a new Gelco-compatible cap, or upgrade to a heavier-gauge aftermarket stainless that fits the same flue diameter. We’ll show you the rusted screen before we swap it.
• Gelco multi-flue caps with bent or torn corner brackets. On older colonials near the North Shore, high wind off the Sound flexes multi-flue caps at the corner brackets. Once a bracket bends, the cap sits crooked and rain starts driving under the lid. Fix: straighten and re-secure where the metal is sound; replace the whole cap when fatigue cracking has set in. We keep common Gelco footprint sizes on the truck.
• Crown spalling above Gelco flue tiles. This is the one we fix most often. The original mortar crown over a Gelco clay tile flue cracks from freeze-thaw cycles. Long Island winters do this faster than Gelco’s own documentation suggests. Chunks start flaking into the flue. Fix: remove loose material, re-form the crown with proper slope away from the flue, and coat with a breathable crown sealer. We won’t just slap patching compound over failing mortar.
• Gelco cap lids with stripped mounting screws. Gelco’s older factory screws are zinc-plated. After four or five winters, they seize and strip. Techs from some national outfits drill new holes and leave the old ones open, which just creates more leak paths. Fix: we extract the stripped screws, chase the threads, and install stainless hardware. Old holes get sealed, not ignored.
• Undersized caps on Gelco flue extensions. We regularly see homes where a previous sweep put a standard cap on a Gelco flue extension that needed a wider footprint. The cap sits too low and restricts draft. Your fire burns lazy, smoke rolls back into the house, and you wonder why. Fix: measure the actual flue outlet, not the tile interior, and fit the cap to match. Draft improves immediately.

Our Gelco Chimney Cap & Crown Process

Here’s how a Gelco job goes from the phone call to the final walkaround:

1. 1
   Call and tell us what you’re seeing. A live person answers, day or night. Describe the leak, the stain, the missing cap. Wendell may be the one picking up.
2. 2
   We arrive with a real window. Background-checked, uniformed, and on time. If the schedule slips, we call you before you call us.
3. 3
   Camera inspection of the flue and crown. We look at the Gelco cap, the crown surface, the flue tile, and the first section of liner. You see the footage. We explain what it shows in plain English.
4. 4
   Parts decision made with you. If Gelco OEM replacement is the right call and available, we use it. If a quality aftermarket stainless cap fits better or outlasts OEM for the same money, we’ll say so. You get the price before any tool comes off the truck.
5. 5
   The fix. Cap replacement, bracket repair, crown re-form and coat. We use proper slope, stainless hardware, and no shortcuts on the flashing interface.
6. 6
   Test and walkthrough. We check the draft, show you the finished work, and give you the 90-Day Done Right Promise in writing. One call brings us back if anything isn’t right.
