Call (626) 657-5513

We’re an independent Gelco service provider in Pasadena – not a factory-authorized shop, but a chimney company that has pulled apart enough Gelco installations to know exactly what fails and why. If you’re hearing water drip into the firebox or seeing rust streaks down the chimney chase, call (626) 657-5513 and we’ll diagnose it in plain words.

How Gelco Products Fail – and How We Fix Them

• Gelco chimney caps with mesh screens clog and rust at the frame. We see this often on Gelco caps installed on Pasadena’s older Craftsman and Spanish Revival chimneys. The screen traps creosote and debris, moisture sits on the steel frame, and the corners rust through. When the cap fails, rain falls straight down the flue. We remove the old cap, confirm the flue tile is intact, and install a properly sized replacement – OEM Gelco when warranty matters, quality aftermarket stainless when the chase is standard.
• Gelco chase covers bow and leak at the corners. Chase covers on prefab chimney chases take direct sun and rain in Pasadena’s dry-wet cycles, and flat steel with no crown pitch will puddle. Gelco chase covers that were never pitched correctly will rust at the corners first. We fabricate or source a replacement with a proper center pitch so water runs off instead of sitting.
• Gelco top-sealing dampers lose their seal after a few seasons of creosote buildup. This is the most common Gelco-specific failure we diagnose in Pasadena. The damper’s silicone gasket gets coated with creosote on the underside, the seal degrades, and cold air pours into the house on winter nights. The fix is usually a thorough cleaning of the damper seat and either a gasket replacement or a full damper swap. Some Gelco damper models accept replacement gaskets; others need the full assembly.
• Loose Gelco cap legs on a crooked crown. Pasadena’s older masonry chimneys often have crowns that have settled or cracked, and a Gelco cap that was anchored to a bad crown will come loose. We re-secure the cap, but only after repairing the crown surface so the cap has something solid to sit on.
• Rust-through from unlined chimneys venting gas appliances. Gelco caps and dampers on chimneys that vent gas furnaces or water heaters in Pasadena get hit with acidic condensate. The condensate eats steel fast, far faster than on a wood-burning chimney. If your Gelco cap is rusting through in under five years, the real problem is likely the absence of a proper flue liner – not the cap itself. We’ll tell you that plainly rather than just selling a new cap.

What Gelco Chimney Repair Costs in Pasadena

A Gelco cap replacement in Pasadena typically runs $350 – $700 depending on flue size and whether the crown needs prep first. A top-sealing damper repair or replacement ranges $500 – $1,200. A chase cover rebuild runs $800 – $1,800 when fabrication is required. The spread comes down to material thickness, access to the roof, and whether the underlying crown or chase needs repair before the Gelco part goes on.

What moves the price? Flue size, roof pitch, whether the old part is still manufactured, and whether the crown or chase is sound. We don’t quote a damper repair if the real problem is a cracked flue tile. You’ll get a written price before we start. Call (626) 657-5513 for a free estimate.
