East Renton Highlands runs a median household income of $140,048, well above the $119,013 median across the rest of the service area. In practice that shows up as more requests for insulated steel doors, higher-end composite finishes, and openers with battery backup rather than the base builder-grade unit. We don't publish a flat price here because the range depends heavily on door size, insulation R-value, and whether the opener gets replaced alongside the door - and we're not going to quote a number we can't stand behind sight-unseen.
What we can say: on a home built around 1974, expect the estimate to include time for header and track work that a newer house wouldn't need, since the opening itself often has to be brought up to spec before a modern door will seat and seal correctly. That's not padding the job - it's the part of a 1974-era install that actually takes the time.
