How Gelco Products Fail - and How We Fix Them

• Gelco UltraPro chimney caps: The stainless mesh on UltraPro caps can separate at the weld points after 8-12 winters in Plainview’s freeze-thaw cycle, especially on south-facing exposures where daytime thawing refreezes overnight. We replace with Gelco OEM mesh or upgrade to a heavier-gauge aftermarket equivalent, depending on your budget and how much tree debris your roof collects.
• Gelco standard galvanized caps: The galvanized coating on entry-level Gelco caps fails first at the seams, not the top. We see this constantly on split-level homes near the Plainview-Old Bethpage border where roof runoff splashes back onto the cap base. We strip the failed cap, inspect the flue tile beneath for hidden spalling, and install a Gelco stainless replacement or a copper upgrade if the homeowner plans to stay put.
• Gelco chimney crowns (poured concrete style): Gelco’s poured crowns develop hairline cracks that widen every February when Plainview’s temperature swings 40 degrees in a weekend. Water gets in, freezes, and lifts the crown off the brick course below. We grind out the cracks, apply a flexible crown sealant rated for Gelco substrates, or pour a new crown with a proper drip edge if the damage has reached the brick.
• Gelco flashing systems: The step flashing on Gelco kits is adequate but thin - 26-gauge in most residential lines. After fifteen years of Nassau County wind-driven rain, the lower corners fatigue and lift. We don’t just caulk over them. We remove the course, install custom-bent 24-gauge step flashing laced into the mortar joints, and counterflash with a matching Gelco base piece or a fabricated copper cap if the wall is stucco.
• Gelco chase covers (prefab chimney applications): Gelco chase covers on factory-built fireplaces pool water at the center seam weld, particularly on the 36-inch and 48-inch widths common in 1980s Plainview colonials. The weld doesn’t fail - the metal beside it does, from galvanic corrosion where the factory coating wore thin. We fabricate a replacement chase cover with a cross-break to shed water, or source a Gelco OEM cover if the dimensions are stock and the homeowner prefers factory-matched parts.

   Call and schedule: A live person answers, asks what you’re seeing, and books a window. No app, no callback queue.

Why Plainview Homeowners Call Hearthstone Chimney Co. for Gelco Work

We’ve been sweeping and repairing chimneys across Long Island for over 42 years, and Russell Haines has spent the better part of two decades working the Old Country Road corridor in Plainview. He learned the trade at Los Angeles Trade-Technical College before deciding the East Coast had more fireplaces worth working on, and he’s built a reputation for finding what the last crew missed - a cracked flue tile hidden under a Gelco cap that looked fine from the ground, a damper that only appeared to seal.

Our Level-2 camera inspections end with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing with no arguing. Our technicians are background-checked, uniformed, and carry professional-grade materials from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. If the chimney is doing its job, you won’t think about it once all winter - that’s exactly the point.
