Common Flex Duct Failures We Fix
Flexible duct is built from a wire helix core wrapped in an inner liner, surrounded by insulation and an outer vapor barrier jacket, and every one of those layers can fail independently. The most common issue we find in Georgetown attics is sag between support points, where flex duct that was hung too loosely, or where the strapping has slipped over time, droops low enough to create a kink. A kinked section can cut airflow to that register by half or more even though the duct looks intact from a distance. The second most common failure is a torn or punctured outer jacket and inner liner, usually from someone crawling through the attic for another repair, or from rodent damage, which lets conditioned air escape directly into the attic space.
Our splicing and repair process depends on what has failed. For a sagging or kinked run, we re-support the duct at proper 4 foot intervals with wide nylon strapping rather than wire, since wire straps cut into the outer jacket over time and eventually cause the exact tear they were meant to prevent. For a torn section, we cut out the damaged length and splice in a new section of matching diameter, joining the inner liners with a sleeve connection sealed with mastic and UL 181 tape, then rebuilding the insulation layer and outer vapor jacket over the splice so there is no thermal or moisture gap at the repair point. A splice done without rebuilding the insulation layer will create a cold spot that can condense moisture in summer, so we treat that step as mandatory, not optional.
We also see a specific installation defect on some homes built during Georgetown's rapid growth years, flex duct connected to a metal collar with just a zip tie and no mastic or UL 181 tape underneath it, which loosens as the plastic tie degrades in attic heat over several years. Any splice or reconnection we perform includes mastic at the connection point before mechanical fastening, since the fastener holds the duct in place but does not seal it. Repairs typically run 150 to 450 dollars depending on how many sections need splicing and how far into the attic we need to work, and we always check the repaired run's airflow at the register afterward to confirm the fix restored full delivery.
