With 1,208 households in West Lake Hills, this isn't a high-volume call area the way some of the bigger suburbs are - Wells Branch or Pflugerville, for instance, sit at greater distances but larger household counts. That smaller base means less exposure to whatever's newest on the market and more houses still running the hardware they were built with in 1988.
The income figure ties back into this directly. At $211,471 median household income, replacing a door outright - rather than patching a 35-year-old torsion setup piece by piece - is a call more West Lake Hills homeowners are willing to make than the area-wide median of $121,750 would suggest. We'll tell you honestly which side of that line your door is on. A single broken spring on an otherwise sound door is a repair. A door with worn track, pitted rollers, and a spring that's already been replaced once is usually cheaper to replace than to keep patching, and we'll say so instead of running the meter on parts that won't outlast the next cycle count.
