Decking in Mercer Island, WA

Decking for Mercer Island homes, from Builders Service Company.

Covered gray deck with white railings and wide stairs on a blue house

Decks are standard on Mercer Island. King County assessor records show 68% of single-family homes have one, with a median size of 410 square feet, so many projects begin with an existing deck that needs replacing.

We build with wood, vinyl and composite decking. The Eastside gets moderate rain, and boards that stay damp grow moss and can rot. Composite and vinyl don’t rot and don’t need staining, which keeps upkeep down. On any surface, plan for drainage and slip resistance. Wood still suits owners who want a natural look and are willing to seal it regularly.

Views shape a lot of deck designs here. Assessor records show 36% of homes have a view and 10% sit on the waterfront. Choose a railing that keeps your sightlines open, and on waterfront lots use corrosion-resistant fasteners and hardware so the structure holds up near the water.

A deck should work as usable outdoor space that fits how you live. Learn more about Mercer Island home exterior services.

Mercer Island decking FAQ

Should I replace my old wood deck with composite?

Composite is a strong option if you want to stop staining and fighting rot. King County assessor records show 68% of single-family homes on the island have a deck, with a median size of 410 square feet. The Eastside gets moderate rain, and damp wood boards grow moss and can rot. We build with wood, vinyl and composite; wood still suits a natural look if you seal it regularly.

What railing works for a Mercer Island view or waterfront deck?

Pick a railing design that keeps your sightlines open. Assessor records show 36% of homes on the island have a view and 10% are on the waterfront. On waterfront lots, use corrosion-resistant fasteners and hardware so the deck holds up near the water. We go over railing and decking choices in wood, vinyl and composite during a free in-home consultation.

Reviews From Our Customers in Mercer Island

  • Happy with it all! Mason left a sign out front though, not sure if he is supposed to come back to pick it up? But the siding and deck work look great so we’re happy!

  • I'm extremely satisfied with the work that was done. The crew who installed our siding was excellent, and it was a pleasure interacting with both Mason and Mr. Kim. I would definitely recommend their services!
