Gelco Chimney Repair in Philadelphia, PA

Gelco Chimney Repair in Philadelphia: What to Know First

We provide independent Gelco chimney repair in Philadelphia, and most jobs are completed in a single visit with upfront pricing that matches the final invoice. Typical turnaround from call to repair is same-day or next-day during the burning season, and we stock common Gelco parts so you’re not waiting on a warehouse shipment. This page is for homeowners in Philadelphia who own a Gelco chimney component - whether it’s a liner, cap, or damper - and need a technician who knows the difference between a Gelco UltraPro and a Gelco ProSeries without reading the label twice. If your chimney is leaking smoke, shedding brick faces, or drafting poorly and you’ve got Gelco hardware in the stack, call us at (866) 580-4069. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them

• Gelco ProSeries stainless liners: We’ve pulled dozens of these from Philadelphia rowhouses where the 316Ti alloy has cracked at the flex points after fifteen to twenty winters of freeze-thaw cycling. The ProSeries carries a lifetime warranty, but the warranty doesn’t cover the labor to extract the failed section or the masonry damage from the leak. We remove the compromised run, inspect the surrounding flue tile with our camera, and install a new Gelco ProSeries section or transition to DuraFlex if the homeowner prefers a heavier-gauge alternative. Done right - and we stand behind it.
• Gelco UltraPro chimney caps: The mesh on these caps is 18-8 stainless, which holds up fine in dry climates but in Philadelphia’s humid summers and salted winter air, we’ve seen the spot-welded seams let go after eight to twelve years. The cap doesn’t fall off; it tilts just enough to funnel rainwater down the flue. We spot this during our Level-2 inspection, match the Gelco base dimensions, and either source an OEM replacement or fabricate a custom cap from Copperfield stock if the flue configuration has shifted.
• Gelco top-mount dampers: The cast-aluminum frame on early-generation Gelco dampers warps slightly after a decade of thermal cycling, and the silicone gasket loses compression. Homeowners in Chestnut Hill and Mount Airy call us when the damper “almost” seals - enough draft loss to spike their heating bill, not enough to notice at a glance. We measure the frame distortion, replace the gasket with OEM Gelco material or upgrade to a HeatShield-compatible damper if the flue needs resurfacing anyway.
• Gelco chimney crowns (poured concrete models): Gelco’s pre-formed crown systems save labor on new construction, but in Philadelphia’s climate the concrete mix is vulnerable to spalling when installers skip the expansion joint at the flue tile interface. We’ve rebuilt crowns in Bella Vista and Queen Village where the original Gelco crown cracked clean through in a five-year span. We remove the failed crown, pour a new concrete crown with proper drip edges and expansion relief, or install a Copperfield crown seal if the substrate is sound.
• Gelco flashing kits: The step flashing in Gelco’s standard kit is 26-gauge galvanized steel, which is adequate but not generous for Philadelphia’s driving rains and the freeze-thaw abuse on north-facing slopes. In neighborhoods like Fishtown and Kensington where the roof pitch is shallow and the exposure is raw, we see rust-through at the ten-year mark. We upgrade to custom-fabricated copper step flashing or match the existing with Famco components, and we always inspect the counterflashing reglets because that’s where the real leak usually lives.

Our Gelco Chimney Repair Process

1. 1
   Call intake: A live person answers, notes your Gelco model if you know it, and schedules a visit - same day if you’re drafting smoke into the house.
2. 2
   Level-2 camera inspection: Our technician runs a camera the full flue length, photographs every joint and surface defect, and explains what we’re seeing in plain English. You get the photos.
3. 3
   Parts decision: We check Gelco OEM availability against our stocked DuraFlex and HeatShield alternatives. If your liner is under warranty, we document the failure for your claim and source the replacement. If the warranty has aged out, we quote both OEM and professional-grade aftermarket with the honest trade-offs.
4. 4
   Repair execution: Background-checked, uniformed technicians complete the work with no-hassle upfront pricing. Most Gelco repairs finish in one visit.
5. 5
   Post-repair test: We run a smoke test or draft gauge check, verify all Gelco hardware is seated and sealed, and clean the work area.
6. 6
   Written guarantee: The 90-Day Done Right Promise goes in your hand before we leave - in writing, no arguing.
