How Gelco Products Fail - and How We Fix Them

• Gelco Ultra-Pro stainless caps clog with creosote in Mount Vernon’s freeze-thaw cycles. The mesh on earlier Ultra-Pro series sits tighter than competing designs, which traps glazed creosote faster when temperature swings hit hard in January and February. We remove the cap, burn off light deposits with controlled heat, and reset it with proper clearance. Heavy buildup means the cap comes back to our shop for ultrasonic cleaning.
• Gelco Lyemance top-sealing dampers lose their seal after seasons of heavy soot. The silicone rubber gasket on pre-2015 Lyemance units hardens when creosote sits against it through summer humidity. During sweep visits we inspect gasket pliability, and if it’s cracked we source the correct Gelco OEM gasket rather than generic substitutes that void the damper’s thermal break function.
• Gelco Multi-Flue caps on Mount Vernon’s two-family homes corrode at the corners. The spot-welded joints on original Multi-Flue caps from the 2000s trap moisture where the cap overhang meets the flue wall. We catch this during camera inspection, clean the affected flue thoroughly, and if the cap is salvageable we seal with HeatShield Cerfractory Foam rather than replace a whole cap for one weak corner.
• Gelco Pre-Fab chimney chase covers pool water when sweep debris blocks weep holes. After a heavy cleaning, fine soot can pack into the factory drain channels on Pre-Fab chase covers. Our techs blow these clear with compressed air and verify drainage before we leave, because a gallon of trapped water above a prefab firebox is a problem no homeowner should discover from inside the house.
• Gelco stainless flex liners sag at the collar in long vertical runs common to Mount Vernon’s taller colonials. The 316Ti alloy holds up fine, but the connection collar at the appliance adapter collects creosote that adds weight over time. We support the liner properly during sweep service, check collar torque to factory spec, and if there’s ovalization we document it with photos so you know before it becomes a draft failure.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, asks what Gelco product you have if you know it, and books a window. We confirm our $89 Seasonal Tune-Up rate or discuss repair pricing if you’ve mentioned symptoms.
2. 2
   Arrival and protection. Our technician lays floor protection, inspects the Gelco cap or damper for visible damage, and sets up the camera rig before touching a brush.
3. 3
   Level 1 or Level 2 inspection with photo documentation. We run a camera through every accessible flue. You see the screen in real time. We note creosote stage, any Gelco part wear, and whether the flue meets NFPA 211 clearance.
4. 4
   Sweep and component service. We brush to bare flue, vacuum all debris, and service Gelco dampers, caps, or collars as needed using OEM or proven aftermarket parts from our DuraFlex, HeatShield, and Gelco inventory.
5. 5
   Final test and written report. We verify draft, confirm damper operation, and leave you with photos, a plain-English verdict, and our 90-Day Done Right Promise in writing.
6. 6
   Cleanup and pricing review. The number on the estimate is the number on the invoice. No add-ons without your okay, which we get in person or by phone before proceeding.
