This page is for homeowners in Los Angeles who already have Gelco chimney components installed and need honest maintenance from a crew that knows the difference between a Gelco Multi-Flue cap and a Gelco Single-Flue model without pulling out a catalog. We are not affiliated with or authorized by Gelco. We are an independent Gelco service provider with no ties to the manufacturer, which means we source parts based on what your chimney actually needs, not what a brand rep wants to move.

How Gelco Products Fail - and How We Fix Them

• Gelco Single-Flue chimney caps in coastal Los Angeles neighborhoods like Venice and San Pedro. The 18-8 stainless mesh on these caps holds up well inland, but within three miles of the Pacific the salt air pits the lower welds and the lid starts to tilt. Water gets in, mixes with creosote, and you get a sulfur-stained flue that looks worse than it is. We remove the cap, assess the flue tiles, and either reseat the original with marine-grade fasteners or replace with a Gelco Multi-Flue if the crown is too far gone for a single point of contact.
• Gelco Multi-Flue caps on pre-1980s Los Angeles chimneys in Highland Park or Eagle Rock. These caps are built for a flat, level crown, but many eastside chimneys were poured with a slight pitch or have settled unevenly over fifty years. The cap skirt gaps, and every Santa Ana wind blows ash back onto the roof. We shim with copper or stainless flashing, never aluminum, and document the crown condition with photos so you see why the extra step matters.
• Gelco Lyemance and Lock-Top top-sealing dampers. The silicone gasket on these energy-top dampers hardens faster in Los Angeles than the manufacturer rates for, because our UV index is higher and the temperature swing from 55-degree mornings to 90-degree afternoons cycles the rubber hard. After year six or seven the seal fails, and you lose conditioned air up the flue even when the fireplace is cold. We replace the gasket with OEM Gelco parts when available, or fit a HeatShield-compatible retrofit if Gelco has backordered the specific Lyemance size, which happened twice in 2023.
• Gelco stainless chimney liners paired with older oil-to-gas conversions. In neighborhoods like Mid-Wilshire and Koreatown, we see 1980s Gelco flexible liners that were sized for the original oil furnace BTU load. The new gas appliance runs cooler, exhaust velocity drops, and creosote builds in the corrugation valleys where the brush doesn’t reach on a standard sweep. We run a rotary polypropylene whip with controlled torque, not a wire brush, to clean without scoring the stainless. Then we verify with a Level 2 camera inspection before we sign off.
• Gelco chimney pots on Spanish Revival homes in Los Feliz and Pasadena. The pot itself doesn’t fail, but the mortar bed does, especially after Los Angeles winter rains follow a dry summer. The pot shifts, cracks the flue collar, and suddenly you’ve got a leak that shows up as a water stain on the plaster ten feet away from the fireplace. We reset the pot with a proper crown wash, use Gelco’s specified base flashing where the original design allows, and seal with a vapor-permeable product so the chimney can breathe.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, notes your Gelco components if you know them, and books a window. Most Los Angeles appointments are within 48 hours.
2. 2
   Arrival and protection. Our technician lays floor protection from the door to the hearth, inspects the visible Gelco cap or damper for model marks, and confirms the scope before touching a tool.
3. 3
   Level 1 or Level 2 inspection. We photograph the flue condition, the cap, the damper mechanism, and any crown or mortar concerns. You see the images on a tablet before we proceed.
4. 4
   Cleaning with the right method. Standard soot gets a wire brush and vacuum. Glazed creosote or a Gelco liner gets the rotary whip. We match the tool to the flue material, not the other way around.
5. 5
   Parts decision if needed. If your Gelco cap, damper, or liner component needs replacement, we explain OEM versus quality aftermarket options, including DuraFlex or HeatShield where they fit better or ship faster. You choose. We don’t push.
6. 6
   Test, document, and guarantee. We run a draft test, provide a written condition report with photos, and back the work with our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing.

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

We’ve been sweeping chimneys in Los Angeles since 1984. That’s long enough to remember when Gelco caps were sold through specialty dealers instead of big-box websites, and long enough to know which part numbers cross-reference to DuraFlex or HeatShield when Gelco has a warehouse gap.

Our 90-Day Done Right Promise means if we miss something, we fix it. In writing. No arguing. Our technicians are background-checked, uniformed, and trained to document every inspection like an engineer and explain it like a craftsman. Photos you can see, a plain-English verdict.

We also carry Olympia Chimney, Famco, and Copperfield lines, so if your Gelco component is discontinued or backordered, we have options that fit and perform. A square deal: no surprises on the bill. We’ll be there when we say.
