What drives fence cost in Washington
Western Washington's problem isn't frost — the 12-inch frost line barely registers — it's moisture. Posts fail at grade from rot long before the panels wear out, so gravel-backfilled or steel-sleeved posts are money well spent. The upside is cedar: Western red cedar is a local product, so the region's default wood costs less relative to other markets. Seattle-area labor runs well above the national average, and wet-season scheduling is a real constraint on install dates.
