Deck Builders in Bellevue

Bellevue decks tend to be larger, and size changes which decisions matter. On a small deck the material choice is mostly aesthetic, because any surface is quick to clean and cheap to re-seal. On a large one it is a standing commitment: a cedar deck of real size needs cleaning and sealing on a cycle, and the honest question is not whether cedar looks better on the day it is finished — it does — but whether that maintenance will still be happening in year five. The second thing size brings is the railing. Railing is priced per linear foot, and on a big elevated deck the run around it can be a surprising share of the total, which makes it a specification decision rather than an afterthought.

What we get called about

Decks & Structures problems specific to Bellevue.

Bellevue lots are larger than Seattle's and the access is usually far better — a driveway a machine can work from changes the cost per square foot of everything. What varies enormously here is the ground. A Somerset hill lot needs walls and slope management; a property on the low land near Mercer Slough sits on peat and organic soils that behave nothing like till and need a foundation approach to match. Two Bellevue addresses ten minutes apart can require opposite answers, which is why we look at the ground before quoting rather than pricing by postcode.

  • A large cedar deck that has outgrown the maintenance anyone will actually do
  • A second-storey deck off a great room with no comfortable route to the garden
  • Railing runs on a big deck costing more than the owner expected
  • Joist spacing on an older frame that will not accept composite boards
  • A deck sized for the elevation drawing rather than for how it gets used

Worth knowing in Bellevue

Work out the perimeter before you settle the size. Doubling a deck's area does not double its railing, and a deeper deck of the same width costs far less per usable square foot than a wider shallow one. It is the cheapest design decision on the whole project.

The method

How we build decks & structures, wherever the job is.

The sequence does not change between neighbourhoods — what changes is the ground it is applied to. Full detail on the decks & structures service page.

  1. 01

    Work out what the deck is for

    A dining deck, a route between levels and a sun trap are different structures at different heights. Deciding that first is what stops a deck being the wrong size in the right place.

  2. 02

    Check the ground and the connection to the house

    Footing depth, how posts meet the ground, and how the frame ties into the building. That connection is the most common failure point on decks we are called out to replace.

  3. 03

    Frame it, then detail it

    Structure first, then the details that let it dry: spacing, flashing where the frame meets the house, and drainage below where the deck is over usable space.

  4. 04

    Lay the surface and set the edges

    Boards run to suit the sightline rather than the shortest cut list, with border and inlay detail where a large deck needs the joint hidden.

  5. 05

    Stairs, railings and lighting last

    Riser lights and rail detail go in once the levels are final, because both are fixed to the finished structure rather than the frame.

What it costs in Bellevue

$35–$90 per square foot installed

Bellevue decks run $35 to $90 per square foot. On the larger structures common here, two lines move disproportionately: the railing, which is priced by the linear foot and grows with the perimeter rather than the area, and anything covered, which is a separate structure sitting on the deck rather than an upgrade to it. Composite costs more per square foot than cedar and less across fifteen years, and on a deck of real size that crossover arrives sooner.

Local questions

Decks & Structures in Bellevue, answered.

General questions about this service are on the service page. These are the ones that only come up here.

Composite or cedar on a large deck?

On a large deck the argument for composite gets considerably stronger, and it is about labour rather than durability. Cedar is a good decking timber and it looks and feels better than any composite on day one, but keeping it that way means cleaning and re-sealing on a cycle — and the effort scales with the area, so a deck twice the size is twice the weekend. Composite costs more up front, needs no sealing, and sheds the algae film a wet climate produces far more easily. Where we would still argue for cedar on a big deck is where it has to match existing timber, or where somebody genuinely enjoys the maintenance and has said so out loud.

Can I put composite boards on my existing frame?

Sometimes, and the answer turns on joist spacing rather than on the frame's condition. Composite boards generally need closer support than older cedar framing was built to, so a frame laid out for timber may not accept composite without additional joists between the existing ones — which is real work, though considerably less than a full rebuild. The other checks are the posts and the ledger, because there is no sense putting a surface with decades in it onto a structure with a few years left. We open up and inspect rather than estimating from the surface, and we will say plainly when a frame is not worth building on.

How do you connect a second-storey deck to the garden?

With a stair run that is treated as part of the design rather than as an exit, which is the difference between a deck people use and one they stand on. A comfortable run has consistent risers, a tread depth you can walk down without concentrating, and a landing where the direction changes — and it lands somewhere that is actually a destination, not the side of the house. On a Bellevue lot with room, turning the run so it arrives facing the garden rather than the fence costs nothing at design stage and changes how often anyone goes down it. Riser lighting is worth including at build, because retro-fitting it means opening up finished work.

Is a covered structure worth it on a Bellevue deck?

It is the single change that most reliably increases how often a deck gets used, and the reason is the climate rather than the design. An uncovered deck in this region is a summer amenity; a covered one is somewhere you can sit in October with the rain coming down, which is most of the year here. Where budget is limited we would rather cover a smaller portion properly than leave a larger area open — a covered section with an open area beside it gives you both, and it costs less than covering everything. It is a separate structure on the deck rather than an upgrade to it, so it is priced separately and needs to be considered at framing.
