How DuraFlex Products Fail - and How We Fix Them

• DF Chase Covers rust through at the seam. DuraFlex chase covers are solid products, but on Alexandria’s older colonials near Seminary Road and Del Ray, we pull covers with rust holes forming exactly where the flange meets the side skirt. That’s a fabrication seam, and it’s where water pools after rain. We replace with a stainless cover sized to your chase and seal it with a proper bead, not caulk.
• DuraFlex multi-flue caps collect debris between flues. The DuraFlex multi-flue cap design leaves a span between the flue openings where leaves, twigs and squirrel nests accumulate. We see this most in Alexandria’s tree-heavy neighborhoods like Rosemont and Beverley Hills. The fix is a custom-cut cap with tighter screening or a single-flue cap set that keeps the span covered.
• Crown damage from spalling. DuraFlex crowns are factory-cast and hold up well, but freeze-thaw cycles on Alexandria brick chimneys cause spalling (the concrete surface flaking off in chunks) within eight to twelve years. If your crown looks like it’s shedding gravel, that’s spalling. We either coat the crown with a waterproof sealant rated for masonry or rebuild it entirely if the cracking goes deeper than the surface.
• Cap legs loosen on older DuraFlex installations. The clamp-style legs on older DuraFlex caps vibrate loose over time, especially on chimneys that see wind off the Potomac. A loose cap rattles, and in a storm it can lift right off. We re-set the legs with stainless hardware and add a bead of high-temp sealant under each clamp foot.
• DuraFlex liner tops sit below the crown line. On some DuraFlex liner installations, the liner terminates too low relative to the crown, which lets water run straight down the gap between liner and flue tile. That’s a slow leak that shows up as damp spots on the ceiling near the fireplace. Our fix is a top plate and cap combination that brings the termination up and seals the void.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and book. A live person answers. We schedule a visit and text you when the tech is on the way.
2. 2
   Camera inspection. We run a camera down the flue and photograph the cap, crown, chase cover, and liner top from the roof. You see every photo.
3. 3
   Written price. Before we touch anything, you get a written scope of work and a written price. No verbal estimates, no “we’ll see once we start.”
4. 4
   Parts decision. We tell you whether OEM DuraFlex parts make sense for your system or whether a quality aftermarket cap from Olympia or Famco gets you the same fit at a lower cost. We carry both.
5. 5
   Install and test. Cap and crown work gets done, then we run a draft test and a water check where it applies. The camera goes back down for a final look.
6. 6
   Documentation and guarantee. You leave with photos, a written record of what was done, and the 365-Day Done Right Promise. If it’s not done right, we make it right.
