How Gelco Products Fail - and How We Fix Them

• Gelco stainless steel rigid liners (Model 316Ti series) develop seam separation at the elbow joints after 15 to 20 years of Fredericksburg’s freeze-thaw cycles. The 316Ti alloy holds up well against creosote, but the factory weld at the 30- and 45-degree elbows fatigues faster than the straight sections. We cut back to sound metal and install a custom-fabricated replacement elbow with a heavier gauge and reinforced collar, then pressure-test the joint before we leave.
• Gelco flexible liners (ProFlex and MultiFlex series) collapse or ovalize where they pass through chimney shoulders in older Fredericksburg homes, especially the pre-1940s brickwork near the Rappahannock Canal Historic District. The shoulder offset is often sharper than the flex rating allows, and decades of sagging make it worse. We pull a new Gelco-compatible flex liner sized to the appliance, or switch to a rigid sectional where the offset permits, with a camera inspection to confirm full roundness before we sign off.
• Gelco top-sealing dampers integrated with liner tops seize in the open position after the stainless cable frays where it exits the flue. The damper body is usually sound; it’s the 1/8-inch aircraft cable that fails. We replace with a marine-grade 316 stainless cable and a reinforced exit gland, not the standard kit, because Fredericksburg’s humidity and pollen load chew through the OEM cable in half the rated life.
• Gelco liner collars and top plates leak at the masonry interface when the original silicone sealant ages out, typically 8 to 12 years. Water tracks down the flue and pools behind the fireplace, staining drywall in homes from Falmouth to Spotsylvania. We pull the top plate, grind to clean masonry, and bed a new Gelco-compatible plate in high-temp silicone with mechanical fasteners - no more sealant-only installations.
• Gelco smooth-wall liners (Model 304 and 316 variants) pit from the inside when homeowners burn unseasoned oak or pine, which is common in Fredericksburg County where firewood seasoning gets rushed before the first cold snap. The pitting starts at the waterline of condensed creosote and progresses to pinhole leaks. We borescope the full length, map the damage, and replace the affected section or the full liner depending on wall thickness remaining - never a patch where the integrity is compromised.

Our Gelco Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers, asks about your appliance type and symptoms, and books a Level-2 camera inspection. We don’t guess over the phone.
2. 2
   Camera inspection and documentation. Our technician runs a high-res borescope the full length of your Gelco liner, photographs every joint, seam, and transition, and gives you a plain-English verdict on the spot. You see what we see.
3. 3
   Parts decision. If the job needs a replacement section, we source OEM Gelco where it matters for fit and warranty compatibility, or use a quality aftermarket equivalent from our DuraFlex or Olympia Chimney inventory when the specification matches and the price saves you money without compromise. We explain the choice before we order.
4. 4
   The repair. Background-checked, uniformed technicians complete most Gelco liner replacements and rebuilds in a single visit. We protect your floors, work from the roof and hearth as needed, and don’t leave until the liner is seated, sealed, and tested.
5. 5
   Pressure test and final camera run. Every liner gets a smoke or air-pressure test to confirm zero leakage at joints and collars, followed by a final camera pass you can watch on the tablet.
6. 6
   Written guarantee and cleanup. We leave you with the 90-Day Done Right Promise in writing, photos of the completed work, and a workspace cleaner than we found it. Clean flue, clear conscience - everything else is just paperwork.
