Gelco Chimney Liner & Rebuild Nationwide

Gelco Chimney Liner & Rebuild in Pasadena: What to Know First

We provide independent Gelco chimney liner & rebuild service throughout Pasadena, with most Gelco liner replacements and partial rebuilds scheduled within a week of your call and completed in one to two days on site. A written price arrives before any work starts, and that price is based on a camera inspection you can watch with us, not a guess from the driveway. If you own a Gelco stainless or flexible liner system in a Pasadena home, especially one installed between 2005 and 2018, this page covers what fails, what it costs, and how we document every step.

How Gelco Products Fail - and How We Fix Them

• Gelco UltraPro flexible liner fatigue at the offset. The UltraPro’s corrugated wall thins at sharp offsets, especially where a Pasadena chimney has been relined through a 45-degree smoke chamber transition. We see circumferential cracking at the bend after 8-12 years. Our fix: cut back to sound metal, install a factory-radius Gelco elbow or transition piece, and pressure-test the joint. We only reuse the existing liner if the upstream section passes a 10-minute air test.
• Gelco stainless rigid liner weld-seam separation near the top plate. The rigid 316Ti series uses a longitudinal weld that can open where the top plate expansion joint binds against a poured crown. In Pasadena, thermal cycling between 90°F summer days and 40°F winter nights accelerates this. We pull the plate, inspect the full seam with a borescope, and either reweld in place or replace the section with a new Gelco rigid tube, matched to the existing diameter so the appliance connection stays correct.
• Gelco ProFlex connector corrosion at the appliance collar. ProFlex uses a lighter-gauge stainless for its appliance connector, and in Pasadena homes with propane conversion or high-sulfur fuel oil history, the lower flue section pits from condensate. We replace the connector with a heavier-gauge Gelco equivalent or, if the appliance venting allows, a DuraFlex SW connector with better acid resistance. The camera doesn’t negotiate - it just shows what’s there.
• Gelco liner-to-thimble gaps causing smoke spillage. Older Gelco installations, common in 1920s Pasadena craftsman homes where the original thimble was never properly enlarged, leave a 1-2 inch annular gap. Smoke finds this path during downdraft conditions, especially when Santa Ana winds hit the south-facing slopes near the Arroyo Seco. We rebuild the thimble with proper clearance to combustibles, install a Gelco termination plate, and verify draft with a digital manometer.
• Gelco liner support failure in tall Pasadena chimneys. The Gelco support plate and clamp system, rated for standard 25-foot runs, sometimes slips in Pasadena’s taller Victorian and Spanish Colonial stacks, especially where earthquake retrofitting has shifted the chimney course. The liner drops, the appliance connection separates, and CO risk follows. We reset with a Gelco heavy-duty support kit or, for runs over 35 feet, fabricate a custom support frame anchored to the chimney wall above the roofline.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   Camera inspection and documentation. We run a 360-degree camera from the appliance connection to the termination cap, recording the full flue condition under Haven Standard Clause 4. You see the footage before we quote anything.
2. 2
   Written scope and price. We deliver a written price, written scope, and written warranty before work begins - Haven Standard Clause 1, H.A.V.E.N. “Have it in writing.” No exceptions.
3. 3
   Parts decision: Gelco OEM or qualified equivalent. We source Gelco factory parts through our Haven buying network when they’re available and competitively priced. If Gelco lead times stretch past safe operation, we specify DuraFlex or HeatShield alternatives that meet or exceed the original spec, with your approval in writing.
4. 4
   Liner replacement or rebuild execution. Our background-checked, uniformed technician arrives with license number visible, performs the work, and pressure-tests or smoke-tests every joint. You get a text when we’re en route.
5. 5
   Photo record and final documentation. We photograph the completed work, the test results, and the warranty card. This record joins your file in our archive, continuous since 2009.
6. 6
   365-Day Done Right Promise activation. If anything’s not right, we make it right. Stamped on every job.

What Gelco Chimney Liner & Rebuild Costs in Pasadena

What moves the price: chimney height, accessibility (steep Pasadena roofs add rigging time), whether the existing liner can be extracted intact or must be demolished in place, and the condition of the crown and top courses. We never recommend a full rebuild without camera evidence you can see for yourself, and we’ll tell you plainly when a repair can safely wait a season.
