Watertown's housing skews older than the service area as a whole. The median build year here is 1976, about six years ahead of the 1982 median across the wider coverage area. That gap matters on a garage door - doors and openers installed in the mid-1970s were built to a different standard than anything sold in the last fifteen years, with different spring tension setups, different track widths, and openers (if there's an opener at all) that predate modern safety-reversal sensors. If your house in Watertown still has its original door, you're likely dealing with hardware that was never designed to pair with a newer opener, which is a common reason replacement jobs here turn into more than just swapping a motor. Homes built after a 1990s remodel or addition are the exception, not the rule, in this particular stretch.
