JS Custom Builds  ·  Eastside Washington

You notice the room.
You never find the seam.

Premium finish carpentry, custom millwork, and full-scope remodeling for the Eastside's most considered homes.

Why JS

Built right, built clean, built to last.

Most of what separates a good room from an unforgettable one happens in the last five percent of the build — the reveal lines, the scribe against stone, the miter you can't find with your fingernail. That five percent is our whole business.

JS Custom Builds is a licensed general contractor specializing in finish carpentry and custom features: cedar saunas, statement bars, furniture-grade built-ins, wrapped beams, and the millwork that ties a high-end home together. The same exacting standard carries every project from first walkthrough to final punch list — no handoffs, no drop in quality at the finish line.

What we do

Three ways to bring us in.

The Craft

Finish Carpentry & Millwork

Trim packages, wall paneling, wrapped and burned-finish beams, door and window systems, and precision scribe work against stone, steel, and everything that isn't square. The detail layer that makes a custom home read as custom.

The Statement

Custom Features

Cedar saunas, home bars, built-in bunk suites, libraries, closets, and one-off furniture-grade pieces — designed around your space and built on site. The rooms guests ask about first.

The Full Scope

Remodeling & General Contracting

Licensed GC services for bathroom, basement, and whole-room transformations. One point of contact managing trades, schedule, and budget — with a finish carpenter's eye on every decision.

Selected work

Proof, not promises.

Photographed on real jobsites, not staged. A few favorites — the full collection lives on the work page.

How it works

A clean process. No surprises.

No. 1

Walkthrough

We meet on site, talk through what you're imagining, and look at the real conditions — because every house lies a little.

No. 2

Scope & Quote

You get a clear, itemized proposal. Materials, timeline, and price in writing before a single board is cut.

No. 3

The Build

Protected floors, clean jobsites, and steady communication — with the same exacting eye on every detail from the first cut to the last.

No. 4

Punch List & Beyond

We walk the finished work together and stand behind it after we leave. The last five percent gets the same care as the first.

Service area

The Eastside & beyond.

Based in Kirkland and serving the greater Eastside, with select destination projects in the mountains and Eastern Washington.
