Decks Built & Restored
We know these lots
Decks built for Issaquah hillsides
Issaquah lots climb the mountains, so slope and drainage are the first things we design for. Highlands homes come with active HOAs, and older neighborhoods have their own quirks.
We’ve built across the Eastside for over a decade, so steep grades and HOA rules don’t slow us down.
- Experienced with steep & mountain-backed lots
- Familiar with Issaquah Highlands HOA rules
- Crews based minutes away in Redmond

Permits, handled
We speak fluent City of Issaquah permitting

- Permit drawings prepared and filed for you
- Built to current Issaquah & WA code
- Setback & critical-area aware on slopes
- Inspection-ready the first time

Go behind the finish. We open up one complete Seattle project—drawings, materials, quality checks, and the hidden work most builders never show you.
Two decks, rebuilt from the footings up
Bellevue, WA
Two elevated decks on a sloped lot, taken down to the footings and rebuilt — new pressure-treated frames, composite tops, and railings brought back to life, all within the original footprint.

A small deck, rebuilt bigger — then a patio to match
Redmond, WA
A cramped 8×10 deck torn down and reimagined as a larger 12×14 — new frame, composite decking and railings, and a composite privacy screen for a corner that finally feels private. Six months later, they brought us back for a 1,000 sq ft tile patio.

James Blair
Magnolia, Seattle May 2026
Craft Boys rebuilt our two-tier deck on a sloped backyard that three other contractors refused to touch. Engineered drawings, permits, hidden fasteners — everything done right, on schedule, and the crew cleaned up every single evening.
Rachel Kim
Bellevue April 2026
We got quotes from five companies and Craft Boys was the only one that explained WHY the old deck failed. New composite deck with cable railings is stunning, and the price matched the written estimate to the dollar.
Michael Torres
Kirkland March 2026
Our 20-year-old cedar deck looked done for. They restored it — sanded, re-stained, replaced the bad boards — for a third of what a rebuild would cost. Honest advice instead of an upsell. Rare these days.
Elena Petrov
Sammamish February 2026
Pergola + deck extension finished ahead of schedule despite the February rain. The crew tarped everything daily and the site was spotless. The 3D visualization beforehand made every decision easy.
David Chen
Mercer Island January 2026
Second project with Craft Boys — deck repair after a winter leak, then full waterproofing with an under-deck drainage system. Their 10-year warranty is real: they came back for the free follow-up inspection unprompted.
Sarah Mitchell
Redmond May 2026
Found them on Thumbtack, best decision of our remodel. They replaced rotten joists other companies missed and finished the new decking so cleanly you can't find a visible screw. Communication was instant.
To guarantee the highest quality, we accept only 3 projects per month.
