This page is for Yonkers homeowners with a Gelco chimney liner, cap, or crown that needs eyes on it. Corrine Halstead runs our Yonkers operation, and she’s spent two decades under chimney caps across Westchester County. As an independent Gelco service provider, we’re not a Gelco factory shop. We’re the crew that sees what their products do after ten years of Yonkers winters.

How Gelco Products Fail - and How We Fix Them

• Gelco factory liner seams opening at the first flue offset. Gelco’s liner kits ship with excellent alloy, but the seam crimps at the first offset above the smoke chamber are where we see split metal. A 30-degree turn creates enough thermal expansion stress to open a seam. We repair with welded seams where the liner diameter allows, or replace with a DuraFlex or HeatShield equivalent if the metal’s gone too thin.
• Gelco chimney caps with warped mounting flanges. The original Gelco cap on many Yonkers homes uses a lighter-gauge mounting collar than their current production. After years of Yonkers weather cycles, the flange warps and pulls the cap off square. Water pours down the flue face. We re-flange and reseal, or swap to an Olympia Chimney cap if the original’s beyond saving.
• Gelco multi-flue covers with rusted screen mesh. The factory mesh on older Gelco multi-flue lids rusts out in under a decade, especially near the Hudson River corridor, where we do plenty of work. Embers make it past the gaps. We re-screen with stainless, not galvanized, and factor the upgrade into the written price.
• Crown cracks where the Gelco cap was installed too tight. We’ve seen plenty of Gelco jobs in Yonkers where the installer torqued the cap’s anchor bolts until the crown fractured. The crown is what fails; the cap just sat there. We grind out the cracks, repoint the crown, and when we reinstall the cap, we use proper torque and seal.
• Mortar joint spalling around Gelco liner entry points. Water intrusion at the liner-to-crown transition is a slow, avoidable death for the mortar around the entry. We repoint, waterproof, and flash that transition zone so the Gelco liner isn’t just sitting in standing moisture after every rain.

Our Gelco Chimney Repair Process

1. 1
   Scope the flue with a camera. Before any Gelco repair is quoted, we run a camera down the stack and record everything. You get that footage, not a sales pitch. Clause 4 of the Haven Standard requires a photo record on every job, and we’ve done it that way since 2009.
2. 2
   Write the price and the scope on paper. A written price, written scope, and written warranty are delivered before anyone starts, not after a tech is already in your home. That’s Haven Standard Clause 1: have it in writing.
3. 3
   Choose parts that match the failure. Sometimes the Gelco OEM part is right. Sometimes a HeatShield or DuraFlex equivalent is the better call because the original part’s design weakness caused the problem. We source through Haven’s buying network to keep the price honest.
4. 4
   Do the repair and show you the proof. We fix the seam, repoint the crown, re-flash the transition, whatever the job calls for. Then we run the camera again so you see the before and after side by side. The camera doesn’t lie, and neither does the quote.
5. 5
   Water test where it matters. If the job involved waterproofing or a cap reseal, we check for moisture ingress before we pack up.
6. 6
   Leave you with the documented record. Written warranty, photo records, completed scope. If it’s not done right, we make it right under the 365-Day Done Right Promise.
