Silver Firs sits about 7 miles from our shop in Everett, and the houses out here don't match the rest of the service area. Across the wider territory, homes typically date from 1968 to 2000 with a median build year around 1990. Silver Firs skews newer - the median year built here is 1997, almost a decade past the area-wide midpoint. That matters because a door installed in 1997 is a different animal than one from the 1970s: steel sectional panels instead of single-piece wood or fiberglass, torsion springs mounted center-over-the-opener rather than side jambs, and openers that were already using circuit boards instead of mechanical relays. With 7,538 households in Silver Firs and a median household income of $153,026 - well above the $116,095 median across the broader area - a lot of these garages also carry heavier doors: insulated steel, sometimes with windows, sometimes double-wide for two-car bays built to a more generous 1990s footprint. We don't guess at what's behind your wall. We ask the build year, because it tells us which spring size and which drive system we're probably loading onto the truck before we even leave Everett.
