Field notes from Duvall installs
Duvall is three jobs wearing one name. The old town on the ridge is 1910s farm-town cottages: plaster-and-lath interiors over shiplap sheathing, Douglas fir framing, narrow brick chimneys. The ridge behind it is 1990s through 2010s craftsman tract, drywall over wood stud with fiber-cement siding, the quickest walls in the area. And the Snoqualmie Valley floor below carries houses built around a river that comes up most winters.
Hardware follows the wall. Plaster gets taped, stepped pilots, low drill speed, and a magnet pass to find lath nails and the fir behind them. Ridge drywall gets cobalt pilots, lag bolts, and a torque driver dialed back for softer modern lumber. Brick chimney breasts get concrete screws set into the brick body rather than the soft old mortar. Valley-floor houses get their equipment planned high instead of low.
Two habits run through every Duvall address. Seismic discipline, because the Puget Sound region moves: anchors land in framing or masonry, big panels get four points, and no large screen hangs on drywall anchors alone. And weather sense. Rain and valley moisture mean exterior penetrations get sealed the day they are drilled, covered-porch runs use outdoor-rated cable, and siding never carries a fastener that should be in a stud.
