How Gelco Products Fail - and How We Fix Them

• Multi-Flue Caps (Series A-1 and A-2): The A-1 and A-2 multi-flue caps use a 24-gauge lid that holds up well in most climates, but Fredericksburg’s freeze-thaw cycles from late November through March stress the corner welds. We see hairline cracks at the seams that let water sheet down between flues, rotting out the smoke shelf below. Our fix: pull the cap, inspect the wash and flue walls with a camera, then reseat with a properly sized replacement or weld repair if the lid is salvageable.
• Single-Flue Caps with Mesh Sides (Series B and B-EL): The B-series mesh is 5/8-inch 18-gauge stainless, which is solid hardware, but the mounting brackets fatigue after a decade of thermal cycling. The symptom homeowners notice first is the cap sitting crooked or rattling in a wind gust. We replace the bracket set with OEM or matched aftermarket hardware and reset the cap with fresh masonry anchors - never the original expansion bolts, which have already failed once.
• Crown Coat Applications on Gelco-Protected Chimneys: Homeowners sometimes call us because water is still getting in despite a Gelco cap. The cap is doing its job, but the crown beneath it was never properly sealed. We’ve found this especially on homes near the Rappahannock Canal Historic District, where pre-1950s chimney crowns were poured without reinforcement and develop radial cracks that bypass the cap entirely. We apply a sloped CrownCoat or similar professional-grade sealant after camera verification, not before.
• Custom Width Caps (Series C Custom): The C-series custom caps are built to order, which means lead times can stretch to three weeks if you need a true OEM replacement. We keep common Fredericksburg flue dimensions in stock and can often fabricate a matched aftermarket cap in-house faster, with the same 304 stainless specs. The trade-off: no Gelco logo on the lid, identical function, lower downtime.
• Chase Cover Replacements (Gelco-Compatible): Gelco doesn’t manufacture chase covers for factory-built chimneys, but we regularly encounter homes where a previous installer paired a Gelco cap with a cheap galvanized chase cover. The galvanized steel rusts through at the drip edge in five to seven years in Fredericksburg’s humidity. We replace with a Copperfield or Famco 304 stainless or copper chase cover, properly cross-broken and caulked, and pair it with a Gelco cap that fits the new flue projection.

Our Gelco Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, 24/7. We book a window that works for you, not a four-hour guess.
2. 2
   Level-2 camera inspection on arrival. Our technician documents the flue, crown, and cap condition with photos you can see on the spot. Russell Haines trained every tech to read a flue the way a doctor reads an X-ray: quietly, carefully, without guessing.
3. 3
   Parts decision with options. If your cap is salvageable, we say so. If it needs replacement, we quote OEM Gelco and quality aftermarket side by side, with lead times for each. No preference unless there’s a functional difference.
4. 4
   Repair or replacement with masonry protection. We pull the old hardware, inspect the crown for hidden cracks, repair or coat as needed, and set the new cap with proper clearances and fasteners rated for your chimney’s brick or flue tile.
5. 5
   Post-repair burn test and photo report. We verify draft and document the finished work. You get the photos, a plain-English verdict, and the 90-Day Done Right Promise in writing.
6. 6
   Cleanup and upfront billing. The number on the estimate is the number on the invoice. We don’t leave until you’re satisfied with the work and the paperwork.
