Siding Replacement Along the Guide Meridian
The Meridian district runs up Bellingham's north side along the Guide, past Bellis Fair and out toward the county line — a corridor that grew in distinct waves, and each wave wore a different skin. The ranches and split-levels of the 1960s and 70s took T1-11 plywood panels. The subdivisions of the 80s and 90s took early composite lap sidings, some from product lines whose failures later taught the whole Northwest an expensive lesson about pressed-board cladding in a forty-inch-rain climate. Walk these streets today and you can read the era of every house in how its walls are weathering.
T1-11 fails at its bottom edge, wicking water up from splash-back until the panel delaminates. The composite laps of the 80s and 90s swell at butt joints and nail heads, then crumble. Both failures share a root cause: wood-based products asked to sit in prolonged wet without a way to dry. Whatever we install in their place gets the detail those walls always lacked — a rainscreen gap that lets the cladding drain and breathe between storms.
