How DuraFlex Products Fail - and How We Fix Them

• DFW series multi-flue caps with cross-break seams - The stamped seam where the lid meets the skirt collects standing water during Sherman Oaks’ brief but intense winter rains. We’ve replaced dozens of these lids on homes south of Ventura Boulevard where the seam rusts through in 6-8 years, not the 15 the homeowner expected. We fit a replacement cap with a welded skirt and drip edge, or move to a Gelco or Famco equivalent if the flue spacing demands it.
• DFC chimney caps with undersized mesh - The factory 5/8-inch mesh on early DFC caps clogs with jacaranda bloom debris each May and June, backing up combustion gases. In Sherman Oaks, where jacaranda lines half the residential streets, we see this every spring. We swap to a 3/4-inch stainless mesh or a custom cap with elevated screen clearance.
• DFL flexible liner top plates with corroded storm collars - The storm collar on DFL top plates is 430 stainless, not 304, and it pits where it meets the plate weld. Water tracks down the liner and pools behind the fireplace damper. We replace the collar with 304 stainless and reseal with a high-temp silicone rated to 600°F, not the generic caulk some crews use.
• DuraFlex Pro crown wash failure on flat-top chimneys - The Pro line’s thin factory crown wash cracks in the first heat cycle if the underlying concrete wasn’t sloped for drainage. Sherman Oaks has hundreds of 1950s-70s chimneys built dead flat. We grind back to sound concrete, pour a new crown with minimum 2-inch overhang and proper drip edge, then coat with HeatShield CrownCoat.
• DFW stainless caps with galvanic corrosion at copper flashing junctions - When a DFW cap sits above original copper step flashing, the dissimilar metals set up a battery effect that rots the cap skirt from the inside out. We see this on the older homes near Dixie Canyon Park. We isolate with a dielectric barrier or specify a copper cap from Copperfield if the homeowner wants matched metals.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, 24/7. We book a window, send a text when the tech is en route, and name the assigned technician.
2. 2
   Camera-scan inspection. NFPA 211 Level 2 inspection with full flue camera run, crown integrity check, and cap fitment measurements. Corrine Halstead and her crew have been reading DuraFlex systems across Sherman Oaks for years - the camera doesn’t lie, and neither does the written quote.
3. 3
   Written price and scope. Before any tool touches the chimney, you get a written price, written scope, and written warranty. Haven Standard Clause 1: have it in writing. No exceptions.
4. 4
   Parts decision. We stock common DuraFlex caps and crowns, but we’re not married to OEM if a HeatShield, Gelco, or Famco part fits better or lasts longer. We explain the trade-off and let you choose.
5. 5
   Repair and test. Cap or crown work completed, water test with hose spray at multiple angles, combustion draft reading if the fireplace is active, and final photo documentation.
6. 6
   Cleanup and record. Job site cleaned, photo record uploaded to your file, and 365-Day Done Right Promise stamped on the invoice. Clause 4 of the Haven Standard requires that documented record - we’ve done it on every job since 2009.
