How Gelco Products Fail - and How We Fix Them

• Gelco Stainless Pro liners with seam separation at the flex joints. We’ve pulled these in Leominster’s older homes near Monument Square where freeze-thaw cycles work the flex sections harder than the manufacturer expected. The seam opens, creosote collects in the gap, and you smell smoke on windy days. We cut back to sound metal, source matching-grade 316Ti stainless from our Haven buying network, and weld the new section with a documented photo of the joint before we close it up.
• Gelco UltraPro smooth-wall liners with acid etching in oil-heat conversions. Leominster has plenty of 1980s capes that switched from oil to gas, then back to oil, and the condensate pattern changes each time. UltraPro’s smooth interior sheds creosote well but the weld bead at the collar can pit when sulfur-heavy oil exhaust sits in a low-drafting flue. We camera-map the etch depth; if it’s under 30 percent wall loss, we sleeve with a HeatShield cerfractory flue sealant system. If it’s deeper, we quote a full Gelco-compatible replacement in writing.
• Gelco rigid liner systems with offset collar fatigue at the thimble. Rigid liners don’t flex, so the thimble penetration takes all the thermal expansion. After fifteen or twenty years of Leominster winters, the collar cracks where it meets the masonry. We find this on camera because the crack faces the wall, not the room. Our fix is a fabricated offset plate from Famco or a Gelco OEM collar if the part is still in production - we show you both options with prices before ordering.
• Gelco top-mount dampers with frame distortion causing liner-top leakage. The cast-aluminum frame can sag if the chimney crown was never poured with a proper cricket to shed water. Water pools, freezes, and the frame twists just enough that the damper seal won’t seat. We rebuild or repour the crown, replace the damper with a current Gelco model or a Copperfield equivalent, and document the crown pitch with a level photo for your record.
• Gelco flex liners with premature corrosion in exterior chase chimneys. Leominster’s nor’easters drive rain into chase covers that were never properly counter-flashed. The liner sits in standing water at the bottom of the chase. Gelco’s 316 alloy resists this better than 304, but no alloy survives constant immersion. We replace the liner, install a proper chase cover with drip edge and storm collar from Olympia Chimney, and show you the old liner’s pitting pattern so you understand why the cover mattered.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   Camera-scan inspection. The camera goes up first. Everything else follows the footage. We run a full NFPA 211 Level 2 inspection with photo documentation of every joint, collar, and wall condition. You get the images same-day.
2. 2
   Written scope and price. Clause 1 of the Haven Standard: have it in writing. We deliver a line-item quote with OEM and quality aftermarket options where they exist. No work starts without your signature.
3. 3
   Parts procurement through Haven buying network. We source Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, or Copperfield materials based on what your system needs, not what we have in the van. Lead time is typically 2-3 business days for Gelco-specific components.
4. 4
   Installation or rebuild with assigned technician. Your tech is named in the paperwork, background-checked, uniformed, and texts when en route. We protect floors, contain dust, and run a combustion or draft test before we pack up.
5. 5
   Documented completion record. Clause 4 of the Haven Standard requires a photo record on every job. You get before-and-after images, test readings, and a written warranty card.
6. 6
   365-Day Done Right Promise activation. If it’s not done right, we make it right. The promise is stamped on your invoice and backed by the full Haven Standard.
