This page is for homeowners in Westchester County who have a Gelco cap or crown already installed, or who are considering one and want to know what actually holds up around here. We’re Top Hat Chimney, locally owned and operated since 1999, and as an independent Gelco service provider we work on these products without any manufacturer tie, which means we tell you the truth about what lasts and what doesn’t.

Key Takeaways

• Gelco caps and crowns are solid mid-range products, but the mounting hardware and sealant are where they fail first in Westchester County winters.
• Most Gelco cap problems we see are repairable without replacing the whole unit.
• We’re an independent service provider, not a Gelco dealer, so we’ll recommend a different brand if that’s what your chimney actually needs.
• Every job comes with our 90-Day Done Right Promise in writing, and we answer the phone around the clock at (914) 537-6479.
• Free estimates, no trip charge inside the county, and $40 off any repair over $200.

How Gelco Products Fail - and How We Fix Them

Gelco caps and crowns are built well enough for most of the country, but Westchester County gives them a workout. We get freeze-thaw cycles from November through March, and a cap that survived ten mild winters in Maryland won’t necessarily survive five up here. These are the specific failure patterns we see on Gelco work in this area.

• Gelco’s stamped steel caps pull loose at the mounting legs. The cap itself is fine. The legs are pop-riveted to the body, and once road salt and chimney moisture work into those rivet points, you’ll see the cap start to lean or rattle in a windstorm. We fix this by drilling out the old rivets and through-bolting with stainless hardware. Half the cost of a new cap and it’ll outlast the original mounting.
• The crown coating on older Gelco units was a single-coat sealant. Crowns that look smooth and black but were installed before roughly 2012 tend to be a single-coat application. Once that coat develops hairline cracks, water gets under it and the crown spalls from the top down. We strip the old coating, repair the crown surface, and apply a two-coat crown sealant that actually soaks into the concrete instead of sitting on top.
• Multi-flue Gelco caps with the center support channels collect debris. On multi-flue installations, the center support channels run just above the flue tiles, and they catch leaves, pine needles, and the occasional bird before it reaches the mesh. In heavily treed areas of Westchester County, like around Bedford or Pound Ridge, we see these channels completely clogged within two years. A clogged channel blocks draft and sends smoke back into the house. We clear them and install a finer mesh overlay if needed.
• The Gelco crown-to-flue-tile joint is the real weak point. The cap gets most of the attention, but the crown is what actually keeps water out of the chimney. On Gelco installations where the original contractor used a cheap silicone instead of a proper crown sealer, that joint opens up within a few seasons. We see this constantly in Westchester County, especially on chimneys with clay flue tiles. The fix is removing the old caulk, prepping the joint, and sealing it with a urethane-based crown sealer that moves with the chimney.
• Gelco’s mesh screens oxidize faster near the coast. If you’re in Mamaroneck, Rye, or anywhere along the Sound, salt air ages galvanized mesh quickly. We swap out the standard mesh for stainless steel screening on coastal Westchester County homes. It costs a little more up front, but you won’t be calling us back in three years to replace rusted-out mesh.

Our Gelco Chimney Cap & Crown Process

1. 1
   You call (914) 537-6479. A live person answers, maybe Wendell himself. You describe the problem. We give you a straight answer on whether it sounds urgent or can wait for a scheduled visit.
2. 2
   We show up and look at the whole chimney. We don’t just look at the Gelco cap. We check the flue, the crown, the brickwork, and the flashing. A loose cap is often a symptom of something else going on underneath.
3. 3
   You see what we see. We run a camera if the chimney merits it, and we show you the footage before recommending anything. If the cap is fine and the crown needs work, that’s what we tell you. If both are fine, we’ll say that too. Wendell’s rule: if it doesn’t need doing, we’ll tell you that too.
4. 4
   You get a flat price before any work starts. The number we quote is the number on the invoice. We decide together whether a repair or a replacement makes sense, and we’ll use OEM Gelco parts or a quality aftermarket equivalent depending on what’s actually better for your situation, not what has a bigger margin.
5. 5
   We do the work and clean up the roof. No debris left behind. The cap is secure, the crown is sealed, and we torque-check the hardware before we come down. On repairs, we test the draft and confirm the flue is breathing correctly.
6. 6
   You get the 90-Day Done Right Promise in writing. If anything we touched isn’t right within 90 days, one call brings us back. No receipts needed, no argument.

What Gelco Chimney Cap & Crown Costs in Westchester County

Here’s what you can expect for common Gelco work in Westchester County. These are flat-price ranges based on what we see, not vague estimates.

What moves the price: roof pitch, chimney height, whether we need a second person on the roof, and the condition of the existing crown. A cracked crown on a steep roof in Yorktown will cost more than a cap replacement on a low ranch in White Plains. Standing offers apply too: $40 off any repair over $200, 10% off for seniors and veterans, and no trip charge anywhere inside Westchester County. Call (914) 537-6479 for an exact quote. The estimate is free, and we’ll tell you if you don’t need the work.

Why Westchester County Homeowners Call Top Hat Chimney for Gelco Work

Because Wendell Pike has been doing this since 1999 and still answers the phone. He grew up in San Diego, which gave him a fine appreciation for why chimneys here need more attention than they do out there. He trained in HVAC and building systems at Palomar College in San Marcos before spending the better part of two decades working chimneys across Westchester County, including plenty of older stone-and-brick homes up near the Teatown Lake Reservation where the fireplaces see real use every winter.

We install and service Gelco, DuraFlex, HeatShield, and Olympia Chimney products, which means we’re not married to any one brand. If a Gelco cap is the right fit, we’ll use one. If a different brand suits your chimney better, we’ll tell you that and quote you accordingly. Every job comes with the 90-Day Done Right Promise, and every estimate is free. We publish our address and license number, and the sweep who shows up at your door is the same person you’ll run into at the hardware store on Saturday.
