How Gelco Products Fail - and How We Fix Them

• Series A stainless caps: weld-seam corrosion at the lid joint. The Series A uses a spot-welded seam where the flat lid meets the vertical skirt. In Littleton’s freeze-thaw cycle - especially on south-facing exposures where daytime sun hits snow-covered metal - that seam opens from thermal flexing. We see this most in Ken Caryl and Columbine Knolls, where homes sit at slightly higher elevation and catch more wind-driven moisture. We replace with a Gelco Series A OEM or a quality aftermarket equivalent with a continuous rolled edge, then seal the base flange with high-temp silicone rated for the cap’s expansion range.
• Series B galvanized caps: base-rail rust-through. The Series B galvanized cap was common on builder-grade installs in Littleton homes built 2010-2018. The galvanized coating fails first at the base rail, where creosote condensation pools. Once the rail perforates, water runs straight down the flue tile. We don’t patch these - the rail is structural. We pull the cap, inspect the flue top for spalling, and install a stainless replacement. If the flue tile is chipped, we address that before the new cap goes on.
• Multi-flue Gelco caps: improper overhang causing crown saturation. The Multi-Flue line needs a minimum 5-inch overhang past the chimney edge to shed water onto the roof, not the crown. We’ve found caps in Littleton’s older Ranch View neighborhoods set flush or with 2-inch overhangs - usually from a previous installer measuring the flue cluster, not the chimney footprint. The crown soaks, freezes, and cracks. We measure the full chimney width, verify the overhang, and reset or replace the cap with correct geometry. If the crown is already cracked, we repair it first.
• Gelco crown coating: UV breakdown on south and west faces. Gelco’s brush-applied crown coating is a cementitious product with polymer additive. It works well when applied thick enough, but the Front Range UV at 5,400 feet degrades the polymer faster than at sea level. We see alligatoring and surface chalking on west faces after 3-4 years, not the 8-10 you’d expect at lower altitude. Our fix: grind back to sound substrate, apply a compatible bonding agent, then recoat with a product formulated for high-UV, low-humidity climates - or pour a new concrete crown if the structural cracks run deep.
• Chimney crown pour: Gelco forms with inadequate drip edge. When a Gelco crown form is used without a built-in drip edge, water sheets down the chimney face and into the masonry joint below the crown. In Littleton, that water freezes behind the brick face and spalls it off by spring. We cut a drip edge into existing pours with a masonry blade, or form a new crown with a 3/4-inch overhang and drip groove. The camera doesn’t have an opinion - it just shows you what’s there - and the photos we deliver under Haven Standard Clause 4 show exactly where the water was traveling.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers. We book a window, text you when the tech is en route, and send a named, background-checked technician in uniform.
2. 2
   NFPA 211 Level 2 inspection with camera. Corrine Halstead’s crew runs a camera down the flue and photographs the crown, cap, and flue top from the roof. You see the footage. We explain what the readings mean in plain terms before any paperwork.
3. 3
   Written price, written scope, written warranty. Haven Standard Clause 1: the price is delivered in writing before work starts. For Gelco jobs, we specify OEM versus quality aftermarket parts, with the trade-offs noted. No verbal quotes.
4. 4
   Parts procurement through Haven’s buying network. We source Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials specifically to keep customer prices honest. If Gelco OEM is back-ordered, we tell you and present the aftermarket equivalent with comparable specs.
5. 5
   Repair, test, document. Cap or crown work is completed, the flue is camera-checked for obstruction, and a photo record is archived under Haven Standard Clause 4. You’ve got documentation for your insurer or future sale.
6. 6
   365-Day Done Right Promise. If it’s not done right, we make it right. The promise is stamped on every job.
