How Gelco Products Fail - and How We Fix Them

• Gelco chimney caps (Model C and Multi-Flue series) - The stainless mesh on older Model C caps can separate at the weld points after 8-12 Cherry Hill winters, especially on south-facing exposures where freeze-thaw cycles hit hardest. We see this most often in the Kings Grant area where mature oak trees drop debris that accelerates corrosion at the weak welds. We replace with Gelco-compatible caps from Famco or source direct Gelco hardware when available, and we reseat the flue collar with high-temp sealant rather than relying on the original friction fit.
• Gelco pre-fab chimney chase covers - The galvanized steel versions installed in 1990s Cherry Hill townhomes (particularly the Crossings and Point of Woods developments) rust through at the drip edge first, not the field. Homeowners spot water stains on the ceiling below and assume it’s flashing. We diagnose with a Level-2 camera inspection, fabricate a replacement from heavier-gauge Copperfield galvanized or upgrade to stainless, and we extend the drip edge 2 inches past the chase wall to shed water away from the siding.
• Gelco chimney liners (Ultrapro and standard flexible alloy) - The Ultrapro’s corrugated walls can develop stress fractures at the offset where the liner turns from vertical to the appliance connector, especially in older Cherry Hill colonials with offset flues in the Barclay Farm and Woodcrest areas. The symptom is a faint chemical odor during shoulder-season burns when draft is weakest. We sleeve the fracture with a DuraFlex compatible section or replace the offset entirely, and we always run a draft test before we leave.
• Gelco top-sealing dampers (Lock-Top and Lyemance series) - The silicone rubber gasket on Lock-Top dampers hardens after 6-10 years and loses its seal, but the cast-aluminum frame is usually sound. Cherry Hill’s summer humidity followed by dry winter heat accelerates this. We replace the gasket with OEM Gelco parts when we can get them, or machine-fit a compatible seal from HeatShield’s gasket inventory. The frame gets inspected for hairline cracks that would make gasket replacement a waste of your money.
• Gelco chimney crown wash applications - Gelco’s crown-forming compounds, when applied too thin by original installers, crack at the flue penetration within 3-5 years. We’ve found this on ranch-style homes near the Cherry Hill Mall built in the 1970s. We grind back to sound concrete, apply a proper 2-inch minimum thickness, and slope it 1/4 inch per foot away from the flue. For badly deteriorated crowns, we pour a new Portland-based crown with embedded mesh rather than another patch.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule - A live person answers, day or night. We ask the model name or age if you know it, and we book a window that works for you.
2. 2
   Level-2 camera inspection - Our technician arrives in uniform, background-checked, and documents the condition with photos you can see on the spot. We give you a plain-English verdict: what’s wrong, why it happened, and what happens if you wait.
3. 3
   Parts decision - We check Gelco OEM availability against quality aftermarket options from DuraFlex, HeatShield, or Copperfield. We explain the trade-off in durability and price, and we never install a part we wouldn’t use on our own homes.
4. 4
   Repair with upfront pricing - The estimate you approve is the invoice you pay. No add-ons, no “while we’re up there” surprises. Most Gelco repairs finish in one visit.
5. 5
   Draft and function test - The chimney either draws the way it should, or it does not - and we will not leave until we know which. We run a smoke test or draft gauge check depending on the repair.
6. 6
   Written guarantee and cleanup - You get the 90-Day Done Right Promise in writing, photos of the completed work, and a jobsite left cleaner than we found it.
