How DuraFlex Products Fail, and What We Find During Inspection

DuraFlex makes a solid product, but no liner lasts forever. Here are the failure patterns we see most often on Fort Worth chimneys, along with what we do about them.

• DuraFlex Pro stainless liner seam separation at the tee connection. The Pro series uses a corrugated single-wall design that handles heat well, but the tee where the liner turns to meet the appliance is the first place we see gaps open up. Fort Worth’s clay-heavy soil shifts with wet-dry cycles, and that settling pulls on the tee connection over time. When the seam opens, flue gases can leak into the chimney cavity. Our fix is a documented inspection finding with photos, then either re-securing the connection or replacing the tee section. We tell you which one the camera supports and show you the footage before a single part gets ordered.
• DuraFlex 316L alloy liner pitting from condensate on gas appliances. The 316L liner is often specified for gas inserts and direct-vent units, but Fort Worth’s humidity plus the acidic condensate a gas appliance produces causes pitting on the inner wall. The pitting is usually visible in the first 5 feet above the appliance. We don’t tell you the liner is shot because we see one pit. We measure the depth of the pitting against the wall thickness and make a call based on whether the liner can still hold flue gases safely. If it can, we say so and schedule a recheck in 12 months. If it cannot, we give you a written quote for replacement before we leave.
• DuraFlex Smooth Wall liner ovaling at the top plate. The Smooth Wall line bends under heat cycling. When the top plate was cut slightly undersized, the liner gets compressed into an oval shape where it passes through the plate. An ovaled liner creates turbulence that slows draft and can cause smoke rollout on cold starts. We see this most often on 1950s and 1960s Fort Worth homes where original clay tile liners were retrofitted. The fix is resizing the top plate opening, not replacing the whole liner, which saves owners a thousand dollars or more in unnecessary work.
• Improper aftermarket connectors used on DuraFlex installs. DuraFlex specifies its own coupling bands and appliance connectors for a reason: the tolerances are tight. When a previous contractor used generic sheet-metal screws or the wrong gauge band, the connection loosens and leaks. During inspection we check every connector against the DuraFlex specification and note any mismatch in the report. If the liner itself is sound, replacing three or four connector bands is a $200 to $400 repair, not a full reline.
• Flex liner kinking from a bad pull through an offset flue. DuraFlex liners are flexible by design, but a hard bend creates a stress point that eventually cracks. Fort Worth chimneys built before 1960 often have slight offsets in the flue that a careless installer tried to muscle through. The kink shows up on camera as a sharp bend with visible creasing at the corrugation peaks. We mark the location, measure the draft loss, and tell you plainly if the liner needs sectioned replacement or if the draft loss is acceptable for your appliance.

Our DuraFlex Chimney Inspection Process

When Hank Delano or one of our techs handles a DuraFlex inspection in Fort Worth, here is exactly what happens, start to finish.

1. 1
   You call, a live person answers. No phone tree, no callback form. We collect the basic details: type of appliance, age of the liner if you know it, and any symptoms you’ve noticed, like smoke smell or animals in the chimney.
2. 2
   We arrive inside the window we gave you. Uniformed, background-checked, and driving a marked truck. We put on shoe covers and lay drop cloths before anything else.
3. 3
   Camera inspection of the full liner run. We run a high-resolution camera from the top of the chimney down through the DuraFlex liner to the appliance connector, recording the whole run. We’re looking specifically for the failure modes listed above, plus creosote buildup, animal nests, and water entry points.
4. 4
   Diagnostic photos and measurements. We document every finding with still images pulled from the footage, plus measurements: wall thickness at pitting sites, draft reading at the appliance, and gap width at any failed connection.
5. 5
   Written findings and a plain-language recommendation. We sit down with you and walk through what the camera shows. If the liner is sound, you get a clean bill and a recommendation for when to re-inspect. If work is needed, you get a written quote with the exact scope before any repair begins. No verbal estimates, no moving targets.
6. 6
   Repair or re-inspection scheduled, guaranteed. If we do the repair, it carries the 365-Day Done Right Promise: a written guarantee good for a full year, with a free return visit if something we fixed fails during that period. If no repair is needed, we note the re-inspection interval and call you when it’s due.

What DuraFlex Chimney Inspection Costs in Fort Worth

Here are the real numbers for the DuraFlex inspection scenarios we handle most often in Fort Worth.

• Level 1 inspection (visual check, no camera): $189 to $249. Appropriate when the liner was installed recently and you just want a trained eye on it before burning season.
• Level 2 inspection with camera: $289 to $349. This is what we recommend for most DuraFlex owners, especially if the liner is more than 5 years old or you bought the house with the liner already installed.
• Real estate inspection (Level 2 with written report for closing): $329 to $389. We deliver the report within 24 hours so your closing isn’t held up.
• Level 3 inspection (partial teardown of chimney structure): $800 to $2,500 depending on access. We only recommend this when the camera shows damage behind masonry that a Level 2 can’t fully diagnose.

What moves the price: roof pitch, chimney height, whether we need a lift or can work from a ladder, and the age of the liner affecting how long the camera run takes. Every inspection gets a written price before we start. Call (682) 255-2144 for an exact quote, and if you mention this page, the estimate is free.
