If that describes your chimney, call us at (855) 950-3861. A live person answers, day or night.

How Gelco Products Fail - and How We Fix Them

• Multi-Flue Gelco caps with 304 stainless hoods - The hood itself holds up, but the spot-welded corners on pre-2015 units fatigue faster than you’d expect, especially where wind tunnels between buildings accelerate metal vibration. We see this regularly on Park Slope and Upper West Side brownstones. Our fix: remove the hood, assess whether the corner seam can be re-welded and sealed, or source a current-generation Gelco replacement hood with reinforced corners. We never band-aid a failing seam.
• Gelco single-flue caps with mesh sides - The 5/8-inch mesh clogs with creosote in New York City at roughly 1.5 times the rate of wider-mesh competitors because so many city homeowners burn compressed logs and lower-grade cordwood. The symptom is a smoky fireplace on windy days, which owners often misdiagnose as a draft problem. We pull the cap, inspect the mesh, and either clean and reset it or replace it with a Gelco cap sized to the flue with proper mesh spacing for your burn habits.
• Gelco crown sealant failures on flat-top crowns - Gelco’s crown coating products, when applied over an improperly prepared surface or in temperatures below 50 degrees, develop micro-cracking within 18 to 30 months. In New York City, we see this most often on DIY applications from the previous fall, when owners rushed to beat the first freeze. We grind the old coating back to sound concrete, apply a bonding agent, and re-coat only when the forecast holds above 55 for 48 hours. Done right, it lasts.
• Gelco band-around-brick cap mounts - The stainless band loosens as freeze-thaw cycles shift the top course of brick, which happens aggressively in exposed Brooklyn and Queens neighborhoods where facades take direct sun then evening shade. The cap tilts, gaps open, and squirrels move in. We remove the band, re-bed the top course if needed, and reinstall with a Gelco mount sized to the actual outside dimensions, not the original spec sheet.
• Gelco custom caps with copper finials - The finial attachment point is a known water trap; on north-facing chimneys in the Bronx and Staten Island, we see galvanic corrosion where the copper meets the stainless base, accelerated by acidic rain and salt air. We replace the finial with a Gelco-matched component or, if the owner prefers, fabricate a solid-cap alternative that eliminates the joint entirely.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your Gelco model if you know it, and books a window. We ask about water intrusion, animal entry, and when you last had a Level-2 inspection.
2. 2
   Level-2 camera inspection on arrival. Our technician photographs the cap, crown, flue interior, and top course of brick. You see the images on a tablet. Frank Calucci trained our senior techs to read a flue the way a doctor reads a chart - methodical, quiet, and honest about what they find.
3. 3
   Parts decision. If your Gelco component is still in production, we quote OEM. If it’s discontinued, we source quality aftermarket from our inventory or, when appropriate, recommend a compatible upgrade from DuraFlex or HeatShield. We explain the trade-off and let you decide.
4. 4
   Written estimate, upfront. The number on the page is the number on the invoice. No surprises.
5. 5
   Repair or replacement. Most Gelco cap and crown jobs finish in two to four hours. We clean the work area, run a final draft test, and document the completed job with photos.
6. 6
   The 90-Day Done Right Promise. In writing, no arguing. If it’s not right, we come back.

Frank Calucci founded this company in 1984 after growing up in Bensonhurst, Brooklyn, where the row houses and old prewar buildings made chimney work a fact of daily life. He learned the trade at New York City College of Technology in Downtown Brooklyn, then spent the better part of three decades working chimneys across the five boroughs before opening Hearthstone. The flue doesn’t care how old the house is. It either draws clean or it doesn’t.
