How Gelco Products Fail – and How We Fix Them

Gelco makes solid, mid-to-premium chimney components, but San Antonio’s climate exposes specific weak points we see repeatedly. Here are the five failure modes we encounter most often on Gelco installations in this area.

• Gelco multi-flue cap mesh deterioration. The stainless steel mesh on Gelco’s larger multi-flue caps takes a beating from Texas sun and the near-constant spring winds. We routinely find the mesh separating from the frame at the corners on caps that are only five or six years old. The fix is usually mesh replacement rather than a full cap swap, and we’ll show you the damage on camera before quoting it.
• Damper cable fatigue in the Gelco top-seal damper line. Gelco’s top-seal dampers use a braided cable that runs down the flue to the firebox handle. In San Antonio homes, we see cable fraying at the pulley or at the handle crimp far more often than at the seal itself. It’s an easy miss on a quick visual inspection, which is why we run the damper through its full range of motion on every Gelco inspection, camera in the flue watching the seal seat.
• Liner-to-cap transition gaps. On Gelco installations where the cap mounts directly over a stainless liner, the transition is often sealed with a bead of silicone that hardens and cracks within a few Texas summers. We find small gaps there that let water track down the outside of the liner, which is exactly where corrosion starts. We reseal with high-temp, UV-rated sealant and verify with a water test on the spot.
• Cast aluminum base corrosion on the Gelco standard cap line. Gelco’s cast aluminum caps hold up well, but on homes near Loop 1604 or in the Hill Country’s higher humidity pockets, we see white oxidation at the bolt heads where the cap anchors to the crown. It’s cosmetic until it isn’t; once those anchors loosen, wind vibration starts cracking the crown concrete. We clean and re-anchor before that happens.
• Flue tile separation behind Gelco inserts. When a Gelco insert or stove was installed as a retrofit, the original clay flue tiles behind it were sometimes already in rough shape. San Antonio’s freeze-thaw cycles, mild as they are, still find those cracks. A camera inspection behind the Gelco unit tells us whether the old flue is still doing its job or whether it’s worth sleeving with a DuraFlex liner instead.

Our Gelco Chimney Inspection Process

1. 1
   Call and schedule. A live person answers, 24/7. We send you the technician’s name and photo before the visit, and that person shows you their photo ID badge at the door.
2. 2
   Arrival and setup. Drop cloths go down around the firebox, and we walk the roof access and flue path before anything else so you know what we’re checking and why.
3. 3
   Visual inspection, Gelco components first. We look at the cap, damper, and visible liner from both the roof and the firebox. Ruben Castellano and his crew have looked at enough Gelco products in San Antonio to spot mesh separation or cable wear before they become real problems.
4. 4
   Camera run. We send a camera down the flue and record the footage. You see stills from the video in your report; nothing gets recommended on our say-so alone.
5. 5
   Parts decision. If something needs repair, we tell you whether the correct fix is Gelco OEM, a professional aftermarket equivalent, or a different trade brand like DuraFlex or HeatShield, and we explain why in plain English. You get a written price before any work starts.
6. 6
   Report and guarantee. Written report with photos, same day. If you approved a repair, it carries our 365-Day Done Right Promise. If it fails within that year, the second visit is free.

What Gelco Chimney Inspection Costs in San Antonio

A straight Level 1 Gelco inspection without a camera runs $149 to $279. Level 2, which includes the camera run and is what we recommend for anyone buying or selling a home with a Gelco unit, runs $299 to $449. A Level 3, which involves partial demolition to access concealed chase areas, starts at $500 and only happens when the first two levels reveal a reason for it.

What moves the price: flue height, roof pitch and access, whether a Gelco insert is in place (which adds setup time), and whether you have a single flue or a multi-flue cap to inspect. Repairs are quoted separately, in writing, before we touch a wrench. Call (903) 515-5079 for an exact quote; estimates are free.

Why San Antonio Homeowners Call Alcott Chimney San Antonio for Gelco Work

Most chimney companies in San Antonio will inspect a Gelco product the same way they inspect anything else. We don’t. We know which Gelco caps fail at the mesh corners, which damper cables fray at the crimp, and which liner transitions leak in this climate. That’s the difference between a checkbox inspection and one that actually tells you what’s next.

We’ve been serving San Antonio homeowners since 2002 as part of the Threshold Group family. Every technician you meet has passed a background check and identity verification. You see their name and photo before they arrive, and they wear a photo ID badge at your door. Every repair comes with a written price before work begins and a written guarantee, free of charge, backed by our 365-Day Done Right Promise. We carry Gelco, DuraFlex, and HeatShield trade materials on the truck because sometimes the best fix isn’t the brand that’s already up there. When Ruben Castellano tells you a part can wait another season, you can take that to the bank – he would rather give you a straight answer today than a vague promise you have to call us back about tomorrow.
