How DuraFlex Products Fail - and How We Fix Them

• DuraFlex 316Ti stainless liners: creosote bridging in shoulder seasons. The 316Ti alloy resists corrosion, but its smooth interior can form glazed creosote deposits when Shelton homeowners burn damp hardwood in March and October shoulder seasons. We use polypropylene brushes sized to the exact liner diameter, never steel on stainless, and follow with a camera pass to confirm the wall is clean. If glazing is present, we apply a magnesium-based modifier during the sweep and schedule a recheck.
• DuraFlex Pro oval liners: ovalization stress at thimble connections. The Pro series oval liners, common in Shelton’s pre-1980 brick chimneys with tight flue passages, develop creosote accumulation at the oval-to-round transition near the thimble. This restricts draft and accelerates soot fallback into the firebox. We remove the thimble plate, hand-clean the transition with non-metallic scrapers, and reseat with a fresh DuraFlex-compatible clamp - not a generic hose clamp that will loosen in two heating seasons.
• DuraFlex 304 alloy liners: premature corrosion from wet wood + Shelton freeze-thaw. The 304 series is rated for dry wood only, but Shelton’s humid summers and freeze-thaw cycles trap moisture in chimneys with poor crown drainage. We see this on homes near the Housatonic River basin where ambient moisture runs high. During cleaning we inspect for pinholing with a borescope; if found, we document it and discuss upgrade to 316Ti rather than sell you another 304 replacement.
• DuraFlex chimney caps: mesh screen clogging from cottonwood and oak catkins. The standard DuraFlex cap with 5/8-inch mesh traps spring debris from Shelton’s mature oak canopy, restricting airflow and causing smoky fires. We remove the cap, clean mesh with a wire brush and compressed air, and check the spark arrestor integrity. If the mesh is corroded through, we source a DuraFlex OEM replacement or a Gelco equivalent with stainless construction - never a big-box cap that voids the liner warranty by creating a reverse draft.
• DuraLiner relining systems: joint separation in offset chimneys. DuraLiner’s telescoping sections can separate at the joint in chimneys with offsets, common in the older homes near downtown Shelton where flues were built around stairwells. Creosote leaks into the cavity, creating a fire hazard you cannot see from below. Our Level 2 inspection checks every joint with a camera; if separation is found, we reseat with DuraFlex’s factory coupling and stainless rivets, not silicone sealant that cooks off in the first hot fire.

Our DuraFlex Chimney Cleaning & Sweep Process

1. 1
   Call and schedule. A live person answers, confirms your DuraFlex product if you know it, and books a window. We ask about burning habits - seasoned hardwood, pellets, or occasional fires - so our technician arrives with the right brushes and expectations.
2. 2
   Arrival and protection. Our technician lays floor and hearth protection, inspects the firebox and damper for obvious damage, and confirms the DuraFlex liner type from any tags or prior documentation.
3. 3
   Level 1 or Level 2 inspection. Every sweep includes a Level 1 visual inspection. If you have not had a camera inspection in three years, or if we find indicators of liner distress, we recommend the Level 2 - photos you can see, a plain-English verdict, no pressure.
4. 4
   Cleaning with brand-appropriate tools. We match brush material to liner alloy: polypropylene for 316Ti and 304 stainless, soft-bristle for DuraLiner’s aluminized surface. No steel brushes on stainless. No shortcuts.
5. 5
   Parts decision if needed. If a cap, clamp, or coupling needs replacement, we show you the worn part and explain OEM versus quality aftermarket options. DuraFlex OEM for warranty-critical components; Gelco or HeatShield equivalents where the specification matches and the price serves you better.
6. 6
   Final test and documentation. We run a draft test, provide a written condition report with photos, and back the work with our 90-Day Done Right Promise - in writing, no arguing.
