This page is for Chesterbrook homeowners who already know they have a DuraFlex liner, cap, or crown component and need someone who will name the problem, show the photo evidence, and put the repair price in writing before any work starts. Corrine Halstead and our crew have worked the Chesterbrook Corporate Center corridor and the surrounding Tredyffrin Township neighborhoods for years. We know which DuraFlex setups were spec’d into the 2015-2022 build wave and how those caps and crowns are holding up after a decade of freeze-thaw cycles. Call (484) 806-9176 when you’re ready to see what the camera shows.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wrap) multi-flue caps: lid separation at the seam weld. The SW series uses a lighter-gauge stainless lid that can fatigue at the corner seams after repeated expansion and contraction. In Chesterbrook, we see this most on homes within a mile of the Valley Forge corridor where wind exposure is higher. Water gets past the separated seam, drips onto the crown, and accelerates spalling. We replace with a heavier-gauge Gelco or Olympia lid matched to the DuraFlex flue profile, or source direct DuraFlex OEM when the flue spacing is proprietary.
• DuraFlex Pro liner top collars: galvanic corrosion where stainless meets aluminum cap base. The Pro series top assembly uses a stainless collar with an aluminum mounting plate. When the cap gasket fails and water pools, you get galvanic action at the interface. We find this during camera inspection when rust streaks appear on the upper flue tiles. Our fix is collar replacement with a dielectric barrier or full transition to a stainless base cap, depending on what the photo record shows.
• DuraFlex relined chimneys: crown cracking from liner vibration transfer. DuraFlex liners flex more than rigid alternatives, and on taller Chesterbrook flues (common in the 1970s colonials near Wilson Farm Park), that vibration transmits to the crown concrete. Hairline cracks widen each winter. We stabilize with crown coating using HeatShield CrownSeal when the structure is sound, or cut and pour a new crown when the rebar is exposed. The camera doesn’t soften the finding. Neither do I.
• DuraFlex factory cap mesh: clogging with box elder and silver maple debris. Chesterbrook’s mature tree canopy drops fine seed debris that mats in the standard DuraFlex 5/8-inch mesh. We’ve pulled caps where the mesh was 70% blocked and the flue was drafting backward. We clean or replace with 3/4-inch mesh where code allows, or add a raised lid design for properties near the Strafford Run watershed where humidity stays high and debris sticks.
• DuraFlex termination caps: wind-driven rain infiltration on low-slope installations. The standard DuraFlex cap skirt is 4 inches. On shallow-pitch roofs common in Chesterbrook’s 1980s construction, wind pushes rain under the skirt and into the flue. We see this as water staining on the smoke chamber walls during Level 2 inspection. Fix is a skirt extension or a custom-fabricated cap with a 6-inch minimum skirt and storm collar, fabricated through our Famco supply line.
