Maple Valley's housing runs newer than most of what we see closer to Kent. The median build year here lands around 2000, well past the 1962-2005 range that covers the wider service area and noticeably later than the service-area median of 1983. That's a real gap - houses built here were mostly framed after garage door standards, opener designs, and spring configurations had already moved past the older one-piece and side-mount setups common in the 1960s-80s stock elsewhere. With about 9,300 households in Maple Valley and a median income of $147,546, well above the broader area's $115,750, this is also a market where owners tend to replace rather than nurse along a door that's falling behind on insulation or noise. Builders working here in the late 90s and early 2000s were already installing sectional steel doors on extension or torsion spring systems with standard-width torsion tubes, not the odd-ball hardware you find in older stock.
