This page is for Bethesda homeowners who already own a Gelco cap or have one spec’d for their chimney. We’re an independent Gelco service provider, not a factory-authorized shop, and we’re not going to pretend otherwise. What we are is familiar with how Gelco caps age on Bethesda roofs, and we will tell you straight if the cap can be saved or if it’s time to replace it.

How Gelco Products Fail - and How We Fix Them

• Gelco stainless steel caps losing their mesh to rust-through. We see this most on the Gelco GCS and Gelco Legacy series, especially where the mesh meets the frame. The screen itself rusts first because it’s the thinnest metal on the cap, and once the mesh goes, you’ve got birds and squirrels setting up house in the flue. The fix is usually a mesh-only replacement when the frame is still solid, which costs a lot less than a whole new cap. If the frame has rust-through too, then it’s a full cap replacement.
• Gelco multi-flue caps with sagged cross-bracing. On wider chimneys, the Gelco MF series gets heavy with snow and ice, and the internal bracing will start to bow over four or five Bethesda winters. A bowed brace lets the cap sit uneven, which collects water instead of shedding it. We can often rebuild the bracing, but if the warp is bad enough, we will tell you honestly that a new cap is cheaper in the long run than nursing an old one.
• Crowns under Gelco caps cracking from freeze-thaw. Bethesda gets enough freeze-thaw cycles that a plain mortar crown will start spalling within ten years, and the Gelco cap just sits on top while the damage happens underneath. By the time you can see the cracks from the ground, water has been working its way into the brick for a while. We repair with crown coat or a full crown rebuild, depending on how far the damage has gone.
• Gelco cap screws backing out on older installs. We have run into more than a few Gelco caps in Bethesda where the original installer used the wrong fastener length and the screws worked loose over time. You’ll hear the cap rattle on windy days. That’s a quick fix: we re-secure it with the right stainless hardware and check the flue tile while we’re up there.
• Aftermarket “Gelco-compatible” caps that don’t seal right. Some homeowners have had a cheaper generic cap thrown on a Gelco flue, and the fit is never quite right. The cap sits loose, water sneaks in around the base, and you get a rust ring on the flue tile. We always check the fit against the actual Gelco dimensions and recommend a proper Gelco cap or a genuinely equivalent option rather than whatever was on the truck.

Our Gelco Chimney Cap & Crown Process

1. 1
   You call, we answer. A live person picks up, which is usually Wendell or a member of his crew. We’ll ask a few questions about what you’re seeing, then set a real arrival window.
2. 2
   We inspect from the roof, not the ground. On a Gelco job in Bethesda, we get on the roof and pull the cap if needed to check the flue and crown underneath. We run a camera down the flue when the situation calls for it.
3. 3
   You see everything. We bring the camera footage and photos down to you, explain what we found, and give you a flat price before any repair starts. “If it doesn’t need doing, I’ll tell you,” Wendell says, and he means it.
4. 4
   We make the decision with you: OEM Gelco parts or quality equivalent. If the cap needs replacing, we can source a Gelco cap or a comparable cap that will actually fit your flue sizing. You’ll know what you’re paying for either way.
5. 5
   The repair happens on the spot most of the time. We carry common Gelco cap sizes and crown repair materials on the truck, so one trip usually gets it done.
6. 6
   We test, clean up, and guarantee the work. Every job gets our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back, no charge.
