How Gelco Products Fail - and How We Fix Them

• Galvanized cap rust-through on the Gelco Economizer series. The Economizer line uses a galvanized base that holds up for about 7 to 10 years in our humidity, then rusts through at the corners where the screen attaches to the lid. We see this most often on exposed chimneys in neighborhoods like Dorsey’s Search and Font Hill where wind-driven rain sits on the cap. The fix is a replacement cap and, if the flue tile is intact, a stainless base instead of galvanized.
• Undersized crown from the original Gelco multi-flue installation. On multi-flue Gelco setups, the factory crown was sometimes poured with less than the 2-inch overhang the masonry code wants. Water runs down the brick face instead of dripping clear. We rebuild the crown with a proper drip edge and a flexible sealant that moves with freeze-thaw cycles, which matters in Ellicott City where we get 20-plus freeze-thaw nights a winter.
• Gelco stainless steel caps with failed screen welds. On some Gelco stainless models, the mesh screen is spot-welded rather than fully seamed. Once a weld pops, birds get in, nests block the flue, and draft drops. We replace the cap with a full-seam screen, either Gelco OEM or a quality aftermarket equivalent that carries the same wind rating.
• Crown deterioration from trapped snowmelt on low-slope Gelco caps. Certain Gelco caps have a nearly flat top profile. Snow sits, melts, refreezes, and the crown underneath absorbs the runoff. In Ellicott City’s January-to-March freeze-thaw cycle, that’s a recurring problem. We address it with a sloped cap replacement or crown coating, depending on the remaining crown depth.
• Gelco single-flue caps that loosen in high wind. We get calls after Ellicott City’s line of spring storms and the remnants of coastal systems that come up the Patapsco valley. The cap’s tension clamps back off. We re-seat the cap, replace the clamp hardware, and check the flue tile for cracks from vibration before buttoning it up.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and book. You reach a live person, not a voicemail. We get your address, the chimney type, and whether you have a Gelco cap or crown already in place.
2. 2
   Level 2 camera inspection. Corrine Halstead or a crew tech runs the camera down the flue to document the liner, smoke chamber, and crown condition from the roof. You see the footage before we quote anything.
3. 3
   Written price and scope. We write down exactly what gets replaced or sealed, which parts are OEM Gelco versus aftermarket, and the full dollar figure. This is Clause 1 of the Haven Standard: a written price before any work starts.
4. 4
   The repair or replacement. We remove the old cap, prepare the crown surface, and install or seal per the written scope. Flashings and chase covers get checked while we’re up there.
5. 5
   Photo record and testing. We run the camera once more after the work, take stills from the roof and from the interior, and hand you the images with the job file.
6. 6
   The 365-Day Done Right Promise. If anything we touched fails within a year, we make it right. No call-tag runaround, no “that’s not covered.”
