Gelco Chimney Liner & Rebuild in Jacksonville, FL

Gelco Chimney Liner & Rebuild in Jacksonville: What to Know First

As an independent Gelco service provider, Hearthstone Chimney Co. of Jacksonville repairs and replaces Gelco chimney liners and performs partial and full rebuilds, with most jobs completed in a single visit and upfront pricing that matches the final invoice. Gelco’s stainless steel and flexible liner systems are common in Jacksonville homes built between the mid-1980s and early 2000s, especially in Ortega, San Marco, and Riverside, where salt air and clay soil movement create conditions the original installers didn’t always anticipate. If you’re seeing water in the firebox, hearing debris fall, or smelling smoke where you shouldn’t, the fix is usually straightforward once we diagnose it properly.

How Gelco Products Fail - and How We Fix Them

• Gelco Stainless Steel Liner (3003 and 304 series): In Jacksonville’s coastal climate, the 3003 alloy liners installed in the 1990s develop pinhole corrosion at the seam welds faster than inland specs suggest. Salt-laden air drawn down the flue during our humid off-season accelerates this. We replace with 316Ti stainless or, if the chase allows, a properly sized DuraFlex equivalent that handles the salt load better.
• Gelco Flexible Liner (pre-2005 corrugated): The early corrugated flex liners flatten at elbows where installers shortcuted the bend radius, especially in the tight chase configurations common in Avondale bungalows. This creates creosote traps and drafting problems. We pull the old liner, inspect the full run with a camera, and reinstall with proper support spacing and a smooth-wall flex if the application allows.
• Gelco rigid-to-flex transitions: The factory collar where rigid meets flex is a known leak point, and Gelco’s original clamp-and-seal method degrades after 15-20 years of thermal cycling. We’ve found this in at least a dozen Arlington homes where the homeowner was told the “whole chimney needs rebuilding” when only the transition and top plate needed replacement. Photos show the difference.
• Gelco top-mount termination caps: The stamped-steel caps from the 1980s and 90s rot through at the mesh weld in five to seven years near the river, not the fifteen the catalog claims. Water gets in, freezes on the rare cold morning, and spalls the crown. We replace with a Copperfield or Famco stainless cap and rebuild the crown with proper drip edges and expansion joints.
• Gelco liner surround insulation: Original installations often skipped mixed-density wrap or used fiberglass that settles in vertical runs, leaving the top third of the liner uninsulated. In Jacksonville, this matters less for freeze protection than for keeping flue gases hot enough to prevent condensation, which is what actually destroys liners here. We reinsulate with proper vermiculite mix or foil-faced wrap depending on clearance.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   Call and schedule: A live person answers, asks the right questions about your chimney’s age and symptoms, and books a Level-2 camera inspection. We show up when we say we will.
2. 2
   Inspect and document: Our technician runs a camera the full length of the flue, photographs every joint, seam, and transition. You see the images on a tablet. We explain what’s wrong, what caused it, and what happens if you leave it.
3. 3
   Diagnose and quote: We identify your Gelco series, check parts availability, and present options - OEM Gelco replacement, compatible professional-grade aftermarket from our DuraFlex or Olympia Chimney inventory, or in some liner-repair cases, a HeatShield cerfractory application if the damage is localized and the existing liner is otherwise sound. The price we quote is the price on the invoice.
4. 4
   Repair or rebuild: For liner replacement, we pull the old, clean the chase, install the new with proper supports and insulation, and seal the top. For rebuilds, we work course by course, matching existing brick where possible, with a poured or precast crown tied to the liner with a proper storm collar.
5. 5
   Test and verify: We run a smoke test or draft gauge check, verify clearances to combustibles, and take after photos. You get a written report with images, the 90-Day Done Right Promise, and our permanent 5% senior and veteran discount applied if it applies.
6. 6
   Clean up and follow up: We haul away debris, sweep the hearth area, and Dale Brinson reviews every job photo within 48 hours. If something’s not right, we already know and we’re calling you.
