How Gelco Products Fail - and How We Fix Them

• Gelco UltraPro stainless caps corrode at the mesh weld points. The 304-grade mesh on UltraPro caps holds up well inland, but Smithtown’s salt air off the Sound accelerates weld-point failure after seven to ten years. We spot this during our Level 2 camera inspection and can source a direct Gelco replacement or upgrade to a heavier-gauge equivalent from Copperfield if the homeowner wants longer service life.
• Gelco Pre-Fab chimney chase covers pool water at the corners. The factory pitch on some Pre-Fab chase covers is insufficient for the heavy, wind-driven rain we get in Suffolk County. Water sits, freezes, and splits the corner seams. Our fix: remove the cover, document the rust pattern with photos, and either reset a properly pitched Gelco replacement or fabricate a custom Copperfield chase cover with a steeper drain angle.
• Gelco Multi-Flue caps gap on offset flue tiles. When Smithtown’s older colonials settle, the flue tiles shift slightly out of plumb. Gelco’s Multi-Flue caps, sized to standard specs, no longer seat square. We measure the actual offset in the field and either modify the mounting skirt or spec a custom-fabricated cap from Famco that follows the real geometry of your chimney.
• Gelco liner collars loosen from thermal cycling. The connection collar on Gelco’s standard flexible liners can back off after repeated heating and cooling, especially if the homeowner burns green or unseasoned wood common in this area. During a sweep, we check collar torque with a proper tool, not by hand, and re-secure with OEM Gelco hardware. If the collar is stripped, we replace it rather than silicone it and hope.
• Gelco top-sealing dampers bind with creosote glaze. The cast-aluminum frame on Gelco’s top-sealing dampers is reliable, but the knife-edge seal collects glazed creosote during shoulder-season burns when flue temps stay in the 250-400°F range. We remove the damper assembly during cleaning, clean the seal face with non-abrasive methods that won’t score the aluminum, and test the seal with a smoke pencil before we leave.

Our Gelco Chimney Cleaning & Sweep Process

1. 1
   Call intake. A live person answers, notes your Gelco model if you know it, and schedules a visit. We ask about burn habits because that shapes what we inspect first.
2. 2
   Arrival and setup. Our technician arrives in uniform, lays protective floor and hearth coverings, and runs a Level 1 or Level 2 inspection per NFPA 211. For Gelco liners and caps, we pay particular attention to connection points and weld seams.
3. 3
   Camera inspection and documentation. We send the camera up the flue and photograph every joint, offset, and termination. You see the images on our tablet as we go. Russell’s approach: “Tell me what you see, and I will tell you what it means.”
4. 4
   Verdict and pricing. We explain what we found in plain English, show you the photos, and give you a written estimate with one number. If the flue is sound, we say so. If a Gelco part needs replacement, we discuss OEM versus quality aftermarket options from DuraFlex or HeatShield.
5. 5
   The work. We complete the sweep, repair, or replacement. Most Gelco jobs finish in one visit because we stock common Gelco hardware and compatible alternatives.
6. 6
   Test and guarantee. We pressure-test or smoke-test the repair, clean our work area, and leave you with the 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork, no arguing.

What Gelco Chimney Cleaning & Sweep Costs in Smithtown

Three things move the price: accessibility of your chimney on the roof, the condition of existing Gelco parts, and whether we find code issues that need addressing before we sign off. We do not upsell. If your Gelco liner has five good years left, we will tell you and schedule next year’s inspection. Call (631) 814-2057 for an exact quote - estimates are free.
