Mercer Island Siding Questions, Answered

Siding in Mercer Island, WA: An Island in the Middle of the Lake

Mercer Island is a city of about 25,000 on an island in Lake Washington, with I-90 crossing the middle of it and water on every side. It built out mostly in the 1950s and 1960s, and it has been quietly rebuilding itself house by house ever since.

Things to Do in Mercer Island, Washington

  • Luther Burbank Park. 77 acres of shoreline on the northeast corner, with a swimming beach, a dog park, and an old dairy barn.
  • Aubrey Davis Park. The lid over I-90, with a trail running the width of the island and the tunnel murals along it.
  • Pioneer Park. 113 acres of second growth forest kept as trails, in three quadrants at the south end.
  • Mercerdale Park. The town center green, with the skate park and the summer concerts.
  • Groveland Beach Park. A quiet south end swimming beach with a dock and lifeguards through July and August.

Mercer Island Culture, Food, and Community

Summer Celebration fills the town center in July, the farmers market runs Sundays, and the island is small enough that most of it is a bike ride from most of the rest. Both Seattle and Bellevue are ten minutes off the island in either direction.

The Mercer Island Homes We Put Siding On

Heavily 1950s and 1960s midcentury, with a steady stream of teardowns and rebuilds mixed in. The older houses carry cedar bevel and plywood panel siding, often under wide low slope eaves that leave the walls exposed. Wind crosses open water from both sides here, so the lake facing elevations almost always fail first, and mature tree cover keeps the shaded walls damp.

Mercer Island Siding Weather in King County

Rain in Mercer Island is rarely heavy, but it is constant, and it arrives sideways when the wind comes off the water. That combination finds every unsealed butt joint, every missing piece of flashing, and every Mercer Island wall where the siding sits too close to grade. It is also why north facing walls in Mercer Island grow moss and stay damp for months. When we detail a wall in Mercer Island, the clearances and the flashing get as much attention as the boards themselves.
