Gelco Chimney Liner & Rebuild in Los Angeles: What to Know First
We provide independent Gelco chimney liner and rebuild service across Los Angeles, with most Gelco liner replacements and partial rebuilds completed in a single visit. Our upfront pricing runs $1,800-$4,500 depending on whether we’re dropping a Gelco stainless liner into an intact flue or rebuilding a compromised chimney structure in a 1920s Craftsman. As an independent Gelco service provider, we stock common Gelco diameters and termination components, source OEM when it matters, and won’t sell you a full rebuild when a liner swap will do. This page is for Los Angeles homeowners who know they’ve got Gelco in their chimney and want a technician who can name the part before he opens the truck. Call (844) 803-1545 - a live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco Stainless 316L rigid liner sections crack at the seam welds after 15-20 years of Los Angeles thermal cycling, especially in hillside homes above 1,000 feet where overnight temperature drops are sharper. We see this in the Pacific Palisades and Laurel Canyon more than flatland neighborhoods. We cut out the failed section, match the gauge and alloy, and back-weld the joint rather than relying on a slip coupling alone.
- Gelco flexible liners in the ProFlex series delaminate internally when homeowners burn manufactured logs with higher chloride content than the liner was specced for. The inner wall separates from the corrugation, reducing draft and collecting acidic condensate. We pull a camera to confirm delamination depth, then replace with a heavier-wall flexible liner or switch to rigid if the flue run permits.
- Gelco top-mount dampers seize in the open position after a decade of Santa Monica marine-layer corrosion, particularly the cast-aluminum throat plates in coastal zip codes. The damper won’t seal, heat flies up the flue, and the homeowner gets a $400 gas bill surprise. We replace with a stainless damper assembly or, if the flue is being relined anyway, integrate a new Gelco lock-top damper into the termination.
- Gelco poured-in-place crown formulations shrink away from clay flue tiles in Los Angeles homes built during the 1970s stucco boom, creating a gap that funnels water directly onto the liner collar. We’ve rebuilt dozens of these crowns in the San Fernando Valley where the original mix was light on Portland. We form and pour a proper crown with adequate overhang, then reset the liner with a new storm collar.
- Gelco ovalizer adapters distort when previous installers forced them into offset chimneys without proper support, common in Mid-Century Modern homes with angled flue runs toward the ridge. The oval section collapses to round, constricting draft and creating a creosote trap. We pull the damaged adapter, re-support the flue with a Gelco-approved offset box, and reinstall with proper clearances.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, asks whether you’ve got a Gelco liner or you’re unsure, and books a Level-2 camera inspection. We arrive in a marked truck, uniformed, with photo ID.
- 2
Inspect and document. We run a camera the full flue length, photograph every joint, seam, and transition. You see the images on a tablet while we explain what we’re looking at. No jargon, no mystery.
- 3
Diagnose and price. We identify the Gelco series, gauge the failure, and present options: OEM Gelco replacement, compatible aftermarket from our DuraFlex or HeatShield inventory if the application allows, or partial rebuild if the masonry is compromised. The price we quote is the price on the invoice.
- 4
Repair with the right parts. Our trucks carry common Gelco diameters from 5″ to 8″, storm collars, top plates, and flex-to-rigid adapters. For uncommon sizes, we source from our Los Angeles warehouse with same-day or next-morning delivery.
- 5
Test and verify. We pressure-test liner joints where applicable, verify draft with a manometer, and run a final camera pass to confirm clean installation.
- 6
Clean up and guarantee. We haul away old material, leave the work area as we found it, and hand you the 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing.

FAQs
No, installing a Gelco liner or completing a rebuild with a qualified independent technician does not automatically void the product warranty, provided the installation follows Gelco’s clearance and connector specifications. We document every installation with photos and a written report so warranty claims, if ever needed, are supported. Call (844) 803-1545 if you’d like us to review your existing Gelco documentation before we start.
Most Gelco liner replacements in Los Angeles are completed in four to six hours, with the technician arriving between 8 and 9 a.m. and finishing by early afternoon. Full chimney rebuilds with integrated liner installation typically require two days, plus cure time for mortar and crown sealant. We schedule so you’re not sitting around waiting.
We stock common Gelco diameters, termination components, and adapters on our trucks and at our Los Angeles warehouse. For discontinued Gelco series or unusual sizes, we source through our distributor network with same-day or next-day availability. You don’t order parts - we handle sourcing, fit verification, and warranty documentation.
Repair is cheaper when the damage is isolated to a single joint, collar, or short section - typically $650-$1,400. Replacement becomes the better value when you have multiple seam failures, internal delamination, or a liner that’s been patched before. We’ll show you the camera footage and give you both numbers so you decide. Call (844) 803-1545 for a free estimate.
Yes, we offer a permanent 5% senior and veteran discount on all chimney services, including Gelco liner and rebuild jobs. We also run a standing $50 off any repair over $250. We’ll apply whichever saves you more.
