How DuraFlex Products Fail – and How We Fix Them

• DuraFlex 316L liner cracking at the chimney offset. In Santa Clarita, the temperature swings between cold canyon nights and hot valley days cause the liner to expand and contract unevenly at the offset, which is the bend where the liner angles to connect with the appliance. Over time, the stainless develops stress cracks at that flex point. We inspect the offset with a camera, and if the cracking is localized, we can often replace just that section rather than the entire liner run.
• Mortar crown separation above a DuraFlex liner. The liner itself may be sound, but the concrete crown that closes off the top of the chimney can crack and let water run down between the liner and the original flue. That water migrates into the brickwork and shows up as spalling below. We repoint the brick, rebuild the crown with a proper overhang and drip edge, and seal the liner top plate to stop the intrusion.
• DuraFlex liner tears at the bottom connection to the appliance. Where the liner connects to a fireplace insert, wood stove, or furnace flue, the stainless can tear from years of heat cycles and slight movement. This is more common in Santa Clarita homes where the fireplace gets hard use through November to February. We remove the damaged section, inspect the host pipe or vent, and install a manufacturer-equivalent replacement section or an aftermarket piece that matches the alloy and wall thickness of the original.
• Flashing failure at the chimney base on tile roofs. Santa Clarita has a lot of concrete tile roofs, and flashing that wasn’t cut into the tile properly will eventually leak. When that happens, water tracks down the exterior of a DuraFlex liner and puddles at the bottom, which corrodes the liner from the outside. We cut proper step flashing into the tile, seal the counter-flashing, and inspect the liner for any corrosion at the base before we call it done.
• Top plate and rain cap corrosion on older DuraFlex installations. The liner might have years of life left, but a rusted top plate lets rain directly into the chimney and accelerates creosote buildup. We replace top plates and caps with DuraFlex or aftermarket equivalents, and we check the spark arrestor screen so it still vents correctly and doesn’t clog with creosote or nesting material. A clogged screen is also a carbon monoxide risk with gas appliances.

Our DuraFlex Chimney Repair Process

1. 1
   Call and dispatch. You call (661) 430-6125. A live person answers, schedules the visit, and tells you exactly what to expect including the inspection fee if one applies. No forms, no callbacks.
2. 2
   Camera inspection. A background-checked, uniformed technician arrives, sets up the camera rig, and runs the flue from top to bottom. You see the images in real time. If the liner is cracked, torn, or corroded, you’ll see it with your own eyes.
3. 3
   Written scope and price. We write down what we found, what it takes to fix it, and the exact dollar amount. That number doesn’t change after the work starts. You approve it on paper before a single tool comes off the truck.
4. 4
   Parts decision. If the liner needs a section replaced, we specify DuraFlex or an aftermarket equivalent that matches the alloy and diameter. If the surrounding masonry needs repair, we handle that in the same visit where possible. If it’s a HeatShield or Gelco application instead, we will tell you what that means in plain terms and why we think one or the other fits the job.
5. 5
   The repair. We do the work, clean the work area as we go, and run a final camera pass to document what was done.
6. 6
   The guarantee. Before we leave, you get the written 365-Day Done Right Promise. If a covered repair fails within one year, we return at no charge. No argument, no prorating.
