Deck Builders in Redmond

The honest problem with a Redmond deck is not building it — it is that an uncovered one is usable for a fraction of the year. This region gives you a reliable stretch of dry evenings in mid-summer and very little either side of it, so a large open deck spends most of its life being looked at through a window. Covering some or all of it changes that arithmetic completely, and it is the single change that most reliably increases how often a deck actually gets used. It is also a structure in its own right rather than an upgrade to the deck beneath it, which means it has to be considered while the deck is being framed rather than added once the boards are down.

What we get called about

Decks & Structures problems specific to Redmond.

Redmond splits into two landscapes with different problems. On the valley floor near the Sammamish River the ground is flat and the water table is high, so drainage design is constrained by how much fall is available and where a system can legitimately discharge. Up on Education Hill, Union Hill and Novelty Hill the lots are large, the access is excellent and the work is design-led rather than remedial. The other Redmond factor is HOA density in the newer developments, where architectural review is a real scheduling item.

  • A large deck that only gets used for a few weeks each summer
  • A cover added later that reads as an addition because it is one
  • Deck framing not sized for the roof somebody wants to add to it
  • An outdoor kitchen or heater with no shelter over it
  • A covered area so enclosed it became a dark room rather than a deck

Worth knowing in Redmond

If a cover is even a possibility later, say so before the deck is framed. Sizing the footings and posts for a roof at build stage adds very little; retrofitting a structure onto framing that was never intended to carry one means opening up finished work.

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 Redmond

$35–$90 per square foot installed

Redmond decks run $35 to $90 per square foot, and a covered structure is priced separately on top of that because it is a separate structure. Posts, beams and a roof have to be carried by footings and framing designed for them, so covering an area is meaningfully more than roofing it. Covering part of a deck rather than all of it is usually the better value and frequently the better design.

Local questions

Decks & Structures in Redmond, answered.

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

Should I cover the whole deck or part of it?

Part of it, in nearly every case, and the reason is that the two areas do different jobs. A covered section gives you somewhere to sit in the rain, keep furniture dry and use a heater or a grill through the shoulder months. An open section gives you the sun when it appears, which in this climate people want more of rather than less. Covering everything also darkens the rooms behind it, because the structure sits directly outside the windows on that elevation. A covered zone at one end with open deck beside it costs less than a full cover and is the arrangement people report using most.

Can a cover be added to my existing deck?

Sometimes, and it depends on what is underneath rather than on the deck surface. A roof adds significant permanent load plus wind uplift, and that load has to travel through posts into footings sized to take it — so the question is whether the existing footings and framing were built with any of that in mind, which on a deck framed as a deck they usually were not. Where they were not, the practical answer is often independent posts for the cover carried on their own footings, passing through or beside the deck rather than bearing on it. That is a real job but a considerably smaller one than rebuilding.

What roof works best over a deck here?

Something that keeps the rain off without turning the space behind it dark, which usually means a solid or louvred roof rather than an open-slat pergola. An open pergola is designed for sun control and this region does not have a sun problem for most of the year — it will look good and buy you very little. A solid roof is the most effective and the most enclosing; a louvred system costs more and lets you have both, opening for the summer weeks and closing for everything else. Where a solid roof would darken a room behind it, translucent panels in part of the structure are a reasonable compromise.

Does my HOA have a say in a covered structure?

Frequently, and considerably more often than for the deck itself. A covered structure has height and a roofline, which is exactly what architectural committees on the newer Redmond plats tend to concern themselves with — where a low deck might pass without comment, a roofed structure visible above a fence line usually needs submission. Because a covered build is also the more expensive half of the project, finding out after design is a costly way to learn. We ask about association requirements at the first visit and, where they apply, put the submission together before anything is ordered.
