How Gelco Products Fail - and How We Fix Them

• Gelco chimney caps in the Multi-Flue series - The 304 stainless steel mesh on older Multi-Flue caps installed across Queens in the early 2000s tends to separate at the weld points after 15 to 18 winters of freeze-thaw cycling. We’ve replaced dozens in Forest Hills and Kew Gardens where the mesh sagged into the flue opening and blocked draft. We fit a new Gelco cap or, if the flue configuration has changed, a custom-fabricated cap from Copperfield with the same gauge stainless and a better cross-weld pattern.
• Gelco Pre-Cast concrete crowns - These were popular on Queens two-family homes built in the 1980s and 1990s, and the concrete mix Gelco used in that era is prone to spalling when saturated by driving rains off Jamaica Bay, then hit with freeze-thaw. The surface flakes, water gets to the brick below, and the crown cracks through. We remove the failed crown, pour a new concrete crown with proper drip edge and slope, or install a Gelco stainless steel crown cover if the underlying brick is still sound.
• Gelco top-sealing dampers - The cast-aluminum throat on Gelco’s top-sealing damper can corrode where creosote accumulates, especially in Queens chimneys that vent oil-fired boilers with high sulfur content. The damper seizes half-open, bleeding heat all winter. We free the mechanism when possible, replace the throat assembly with OEM Gelco parts when it’s not, and always check the lower stainless flue for creosote glazing while we’re up there.
• Gelco chimney liner sections - The original Gelco flexible liner, the pre-2010 version with the smoother wall corrugation, can develop circumferential cracks at the elbows where Queens chimneys offset around breast walls in pre-war construction. We camera every offset, and if we find a crack we sleeve with DuraFlex or replace the section with current-spec Gelco liner that has the heavier corrugation profile.
• Gelco wall-thimble assemblies - On exterior chimney runs common in Astoria and Sunnyside row houses, the Gelco thimble can pull away from the masonry as the wall settles, breaking the seal and allowing CO to track into wall cavities. We reseat with firestop-rated packing and a new Gelco thimble, or switch to a HeatShield cerfractory seal if the gap is irregular from decades of settling.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing - water stains, draft problems, visible brick damage - and books a Level-2 camera inspection. We serve Queens with background-checked, uniformed technicians.
2. 2
   Camera inspection and photos. We run a chimney camera and photograph every Gelco component we can access. You see the footage on site. Russell Haines or one of our senior techs gives you a plain-English verdict: what’s wrong, what caused it, and what happens if you leave it.
3. 3
   Parts decision. If your repair needs a Gelco part, we source OEM when it’s available and cost-effective. When Gelco lead times stretch past two weeks or the part is discontinued, we specify quality aftermarket from DuraFlex, HeatShield, or Copperfield that matches or exceeds the original spec. We tell you which we’re using and why.
4. 4
   The repair. Most Gelco chimney repairs in Queens are completed in a single visit. Mortar repointing, cap replacement, damper repair, small crown pours - our trucks carry the materials. Larger rebuilds get scheduled with a fixed start date.
5. 5
   Post-repair test and documentation. We run another camera pass or draft test to confirm the fix holds. You get photos, a written summary, and our 90-Day Done Right Promise. If it’s wrong, we’ll say so. If we fix it, it stays fixed.
6. 6
   Cleanup and final walkthrough. We tarp the work area, haul debris, and walk you through what was done. The number on the estimate is the number on the invoice.

Why Queens Homeowners Call Hearthstone Chimney Co. for Gelco Work

We’ve been sweeping and repairing chimneys across Queens for over 42 years. In that time we’ve worked on Gelco products installed by roofers who are long retired, in neighborhoods from Bayside to the Rockaways, and we’ve learned what fails and what doesn’t.

Our 90-Day Done Right Promise means if a Gelco cap we installed leaks or a repointing job opens up, we come back. No paperwork to find, no argument. Our technicians are background-checked and uniformed, and most Gelco repairs are done in one visit because our trucks carry DuraFlex, HeatShield, and Gelco inventory. When Gelco parts are back-ordered, we don’t leave you hanging - we have relationships with Olympia Chimney, Famco, and Copperfield to keep the job moving.
