How Gelco Products Fail - and How We Fix Them

• Model A-1 and A-2 stainless caps: weld-seam corrosion at the lid joint. These single-flue caps use a folded seam where the flat lid meets the vertical skirt. In Bellevue’s marine climate, that seam traps condensation from Pacific air masses eight months of the year. We see the seam rust through before the mesh fails. Our fix: cut off the lid, re-weld with 304 stainless filler, or replace with a Gelco-replacement cap from our Haven buying network if the mesh is also fatigued.
• Multi-flue Model C caps: corner-post settling on older Bellevue chimneys. The C-series sits on four corner posts with adjustable base brackets. On 1960s and 1970s chimneys in neighborhoods like Lake Hills and Factoria, the original crowns have minor slope settlement that tilts the cap frame. Water then pools at the low corner and accelerates crown spalling underneath. We shim with stainless wedges, re-seal the base with CrownCoat or a full crown rebuild if the concrete has lost structural integrity.
• Model B wind-directional caps: bearing seizure after pollen season. The B-series rotating hood uses a simple bronze bushing that seizes when pine pollen and urban particulate pack the race. In Bellevue, the Douglas fir and cedar pollen load peaks late April through May. A seized B-cap stops drafting and forces smoke into the room. We disassemble, clean the race with solvent and brass brush, repack with high-temp bearing grease, or replace the rotating assembly if the hood has warped from overheating.
• Gelco copper caps: electrolytic pitting where dissimilar metals contact the flue tile. Gelco’s copper line is beautiful but galvanically active against aluminum or steel flue extensions some Bellevue homeowners added during 1980s insert installations. The pitting starts at the cap base and works upward. We isolate with a stainless transition collar, or if the copper is too thin, we source a replacement through our Olympia Chimney supply line and match the patina age as close as possible.
• Crown wash failure beneath Gelco caps: the hidden problem. Gelco caps are well-built, but no cap saves a crown that was poured without proper slope or reinforcement. We pull the cap, sound the crown with a hammer, and camera the flue. If the crown is cracked through to the flue liner, we quote a CrownSeal coating or a formed concrete rebuild before resetting your existing Gelco cap. Clause 4 of the Haven Standard requires we photograph the crown condition and show it to you before any cap goes back on.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers. We ask for the Gelco model if you know it, the chimney age, and what you’re seeing. We book a two-hour arrival window.
2. 2
   On-site Level 2 inspection. Corrine or a uniformed tech arrives with license visible, texts when en route. We camera the flue, inspect the crown and cap from the roof, and document everything. The camera doesn’t guess. Neither do I.
3. 3
   Written price, written scope. Before any tool comes out, you get a single-page quote: parts, labor, warranty term, and what happens if we find additional damage. No verbal estimates. No surprises.
4. 4
   Parts decision. If your Gelco cap is repairable, we repair it. If replacement is smarter, we source OEM-equivalent Gelco or a compatible cap from our DuraFlex or Famco lines, whichever fits your flue configuration and budget. We explain the trade-off and let you decide.
5. 5
   Repair and test. Cap off or crown repaired, we run a draft test with a manometer, check for proper clearance to combustibles, and re-camera if the flue was disturbed.
6. 6
   Photo record and warranty. You get the inspection photos, the repair photos, and a written warranty under the 365-Day Done Right Promise. Clause 4 of the Haven Standard: documented record on every job, no exceptions.

What Gelco Chimney Cap & Crown Costs in Bellevue

Price moves with roof pitch, chimney height, and whether we need scaffolding rather than ladder access. Bellevue’s hillside lots in Somerset and Cougar Mountain add time and equipment. Every estimate is free, written, and valid for 30 days. Call (425) 696-0387 for your exact number.

Why Bellevue Homeowners Call Emberly Chimney Cleaners Bellevue for Gelco Work

We’ve inspected over 38,000 chimneys since 2009, and a healthy share of those were Gelco caps in Bellevue homes where the owner wanted the part fixed, not upsold. Corrine Halstead and our crew know the Gelco line well enough to spot the difference between a cap that needs replacement and one that needs a $40 bearing cleaning. If your Gelco product is discontinued or the lead time stretches, we have DuraFlex and HeatShield alternatives in our Haven buying network, priced honestly because we buy at scale.

The 365-Day Done Right Promise means if the cap leaks, the crown cracks, or the draft drops, we come back and make it right. Background-checked techs, license on the page, text alerts, and a live person on the phone 24/7. That’s the Haven Standard.
