How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SS (stainless steel chimney liner) - thermal fatigue at the tee body. In Shelton’s freeze-thaw climate, the SS tee body sees constant expansion and contraction. The weld seam at the snout cracks after 8-12 years, not from bad material but from thermal cycling. We cut back to sound metal, fit a DuraFlex OEM replacement tee, and back it with a custom-fabbed support plate so the new joint doesn’t carry the same load.
• DuraFlex Pro (smooth-wall liner) - creosote bridging in the corrugation valleys. The Pro’s smooth interior wall still has micro-corrugations that trap glazed creosote when homeowners burn wet hardwood, which is common here with the oak and maple stockpiled from local tree work. We run a rotary poly brush sized to the exact Pro diameter, then verify clearance with a camera before signing off. Skip the camera and you’re guessing.
• DuraFlex SW (single-wall connector) - draft hood spillage on gas conversions. Shelton’s older colonials up near Huntington Center often have shallow fireboxes where a direct-vent gas insert gets crammed into a DuraFlex SW run that’s too short to develop proper draft. The spillage isn’t a gas valve problem; it’s a venting geometry problem. We extend the SW run with an adjustable elbow kit or recommend a DuraFlex DV (direct-vent) liner if the appliance allows.
• DuraFlex PelletVent Pro - auger feed area corrosion from condensation. Pellet appliances in Shelton basements run into 45°F masonry in shoulder season. The PelletVent Pro tee collects acidic condensate that eats the 304 stainless from the inside out. We replace with 316L upgrade where the code allows, or reroute the tee to a warmer wall chase with proper slope for drainage.
• DuraFlex DV (direct-vent) - co-linear termination blockage from cottonwood fuzz. The co-linear cap on DV systems sits low-profile and clogs with seed fluff from the cottonwoods along the Housatonic River properties in spring. The pressure switch trips, the unit shuts down, and a homeowner gets a “failed gas valve” diagnosis from someone who didn’t look outside. We pull the cap, document the blockage with photos, and swap to a high-rise termination if the location allows.

Our DuraFlex Fireplace Services Process

1. 1
   You call, we answer. A live person at (475) 265-6822, any hour. We ask for the DuraFlex model or series if you know it, the symptom, and the appliance age.
2. 2
   We show up when we say. Background-checked, uniformed technician, truck stocked with DuraFlex fittings, OEM tees, and quality aftermarket alternatives from Olympia Chimney and Famco where the job allows.
3. 3
   Camera inspection first. Level-2 inspection with photos you can see on the spot. We name the problem, show you the evidence, and give a plain-English verdict - no jargon, no theater.
4. 4
   Upfront pricing, your choice on parts. OEM DuraFlex part with full warranty, or quality aftermarket if the application fits and you want to save. The number on the estimate is the number on the invoice.
5. 5
   The repair, the test, the cleanup. We fix it, pressure-test or draft-test per the appliance type, run it through a full cycle while you watch if you want, and leave the hearth cleaner than we found it.
6. 6
   The 90-Day Done Right Promise. In writing. If it’s not right, we come back. No paperwork to find, no arguing.
