This page is for homeowners who already have a Gelco product on their chimney and need it fixed right - or replaced with something that fits properly without cobbling. If you’re seeing rust streaks, water in the firebox, or a cap that’s come loose after a Santa Ana wind event, call (844) 803-1545. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them

• Gelco Multi-Flue caps (Model M series): The expanded mesh on these can sag where it bridges two flue tiles, especially in Los Angeles homes with clay flue liners that have settled unevenly over decades. We see this in Mid-Century builds from Sherman Oaks to Pasadena. Our fix is a custom-fabricated sub-flange that levels the mounting surface before the cap goes on, rather than forcing the cap to conform to a crooked chimney top.
• Gelco stainless single-flue caps (S-series with wind band): The wind band - that extra rim around the edge - catches debris and traps moisture against the crown edge. In coastal Los Angeles neighborhoods like Venice and San Pedro, the salt air accelerates the corrosion where the band meets the mesh. We remove the failed band, assess the crown beneath, and either reseat the cap on a repaired crown or move the homeowner to a Gelco cap without the band if wind isn’t the primary concern.
• Gelco copper caps (C-series): These develop pinhole leaks at the solder joints after 12-15 years due to thermal cycling - Los Angeles sees 40-degree temperature swings some days, which flexes the metal. The patina hides early corrosion. We pressure-test the cap on the truck before reinstalling, and we keep copper solder and flux rated for chimney temperatures, not standard plumbing grade.
• Gelco crown sealant failures: When a Gelco cap is installed on a crown that was previously coated with a flexible sealant, the sealant outgasses and leaves a oily film that prevents the cap’s base flange from bedding properly. We’ve pulled caps in Los Feliz that were “sealed” three times and still leaked because nobody cleaned the substrate. We grind to sound concrete, apply a bonding primer, then set the cap in fresh mortar.
• Gelco outside-mount caps (OM series for deteriorated flue tiles): These rely on a tension band that grips the chimney exterior. In Los Angeles, stucco chimneys from the 1960s-80s often have hollow spots or wire lath corrosion behind the surface. The band crushes the stucco instead of gripping. We sound the chimney exterior first, sister in blocking where needed, and mount to solid substrate - not to a facade that’s going to crumble.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing, and books a window. We don’t do “sometime Tuesday” - we give you a two-hour window and call when we’re en route.
2. 2
   Level-2 camera inspection. Our tech runs a camera down the flue before touching the cap or crown. We document water staining, liner condition, and any blockage. You see the photos; we give you a plain-English verdict on whether the problem is the cap, the crown, or both.
3. 3
   Parts decision. If your Gelco cap is under ten years old and the model hasn’t been discontinued, we’ll quote OEM. For older units or discontinued lines, we source quality aftermarket that matches Gelco’s 304 stainless or copper specs - never builder-grade galvanized that’ll rust through in three years.
4. 4
   The repair. Crown work gets ground to sound material, formed, and poured with high-early-strength mortar rated for chimney exposure. Cap installation gets a mortar bed, not just screws into crumbly crown. We check draft and spark arrestor clearance before we descend.
5. 5
   Test and document. Water test on the crown, smoke test for draft, photos of the finished work uploaded to your job record. You get a written invoice with the 90-Day Done Right Promise printed on it.
6. 6
   Cleanup and close. We haul off the old cap and debris. Most Gelco cap and crown jobs in Los Angeles take three to five hours from arrival to departure.

What Gelco Chimney Cap & Crown Costs in Los Angeles

These are real numbers for Los Angeles - not national averages, not bait-and-switch ranges.

Steep roofs, tile roofs that require walk pads, or chimneys over 25 feet add labor time. We tell you before we start. Estimates are free - call (844) 803-1545 for an exact quote on your Gelco chimney cap or crown.

Why Los Angeles Homeowners Call Hearthstone Chimney Co. for Gelco Work

We’ve been sweeping and repairing chimneys in Los Angeles since 1984. That’s long enough to have installed Gelco caps when they were still branded under earlier company names, and to know which Los Angeles neighborhoods have the chimney construction that fights back.

Our 90-Day Done Right Promise means if the crown crack reopens or the cap seal fails, we come back. In writing, no arguing. Our technicians are background-checked, uniformed, and carry Gelco-compatible hardware plus backup brands - DuraFlex for liner work, HeatShield for resurfacing - so we’re not stopping the job because one part is backordered.

Russell Haines started this company with the idea that a chimney sweep should explain what he found well enough that the homeowner could repeat it to their neighbor. Find what’s wrong, say it plainly, fix it right. That’s still how we operate.
