Second-story wood deck with gable roof cover, railings and stairs

Deck Builder in Snohomish & King County, WA

NW Structures builds wood and composite decks for homeowners across Snohomish and King County, from a simple backyard deck to a second-story deck with stairs and a cover overhead. Deck looking tired? We resurface it with new decking, railings and stairs. With 25 years of building behind us, you get one licensed and insured builder from the first site visit to the finished deck.

How it works

  1. Tell us about the deck. Send the form below or call (425) 209-6553: size, height, wood or composite, new deck or resurfacing.
  2. Site visit. Dan looks at the spot (or your existing deck), the access and the ground before quoting.
  3. Written quote and permits. A clear price for the deck you talked about. If it needs a permit, we take care of it.
  4. The build. We show up when we say we will and keep you posted on each step.

What our customers say

Questions we hear a lot

Wood or composite?

Wood costs less up front and has the classic look. Composite costs more but needs far less upkeep. We’re happy to price both so you can compare.

Can you resurface my deck instead of replacing it?

Often, yes. If the framing is in good shape, we replace the decking, railings and stairs. If it isn’t, we’ll tell you before we quote.

Do I need a permit for a deck?

Many decks do, depending on height and whether the deck attaches to the house. We’ll tell you what yours needs and take care of it.

Can you build a cover over my deck?

Yes. Attached or freestanding, with shingle or clear roofing. See our patio covers.

How much will it cost?

It depends on size, height, materials and stairs. We give you a written quote after seeing the site.
