Deck Contractor in Redmond, WA
From soft boards to a full rebuild, we make your deck safe and good-looking again. Soft boards, wobbly railings and a dark line where the deck meets the house usually mean water has reached the joists or the ledger. We check the whole structure first, repair what can be saved and rebuild what cannot, with flashed ledgers, taped joists and posts that stay dry. We serve homeowners across Redmond and nearby Sammamish and Woodinville.

Why deck repair comes up so often in Redmond
Attached wood decks are standard on Redmond homes from the 1970s through 90s, and many are now old enough that the framing is failing even if the surface was replaced. On Education Hill and in Bear Creek, decks under trees grow moss and stay slick and wet. We commonly find rotted ledgers, joist hangers rusted through, and posts decaying at grade. We replace damaged framing, add ledger flashing and new hardware, and rebuild stairs and railings for safety. For a full replacement, we build with cedar or composite and design the frame for Redmond’s damp, shaded conditions.
Redmond grew quickly from the 1970s onward, and its housing reflects that. Education Hill and Grass Lawn are full of 1970s and 80s two-story homes and split-levels, many with cedar or hardboard lap siding and attached wood decks. Idylwood and the slopes toward Lake Sammamish have a mix of older cabins converted to year-round homes and newer view houses. Bear Creek and the hills to the east have larger 1980s through 2000s homes on wooded lots. Downtown and Overlake have added many townhomes and apartments in the last two decades, often with small balconies and mixed siding materials.
The Sammamish River valley runs through the middle of Redmond, and cool air and fog settle there on winter mornings, keeping lower walls and decks wet longer. The surrounding hills, especially Education Hill and the Bear Creek area, are heavily wooded, so many homes sit in shade for most of the day. Rain comes in long, steady stretches rather than short bursts. Wood that never fully dries between storms is the pattern behind much of the rot we find, along with moss on roof edges and decks.
Our crew comes out from our Woodinville office, and we also work in nearby Sammamish, Woodinville, Kirkland and Bellevue.

Neighborhoods and permits in Redmond
Education Hill homes stay shaded under big trees, and the damage concentrates at north walls, fascia and decks. Grass Lawn and Overlake have more sun but older flashing details, so window sills and roof-to-wall joints fail first. Idylwood, close to Lake Sammamish, sees moisture at lower siding and docks or stairs near the water. Out toward Bear Creek, larger homes with tall walls and big decks carry the most exposed surface.
Swapping out a few rotted siding boards or a small section of trim like-for-like often doesn’t need a permit. Replacing joists, posts or wall framing, building a new deck, or residing a large wall is a different story. Our office contacts the City of Redmond ahead of time, files what is required, and lines up inspections so the homeowner isn’t stuck chasing paperwork.

Deck contractor in Redmond: cost and timing
Most common causes
Old hardware
Rusted nails, hangers and bolts lose their hold, which makes railings and stairs loose and unsafe.
Posts sitting in water
Posts buried in soil or set flat on concrete wick water up and rot from the base.
Tops of joists staying wet
Water sits on top of joists under each board. Without joist tape, the framing rots long before the decking looks bad.
What drives the price in Redmond
Deck work in Redmond is priced by size, height, the condition of the framing and the materials you choose. Replacing boards and railings on solid framing costs much less than a full rebuild, and composite costs more up front than wood but saves on upkeep. After the free inspection you get a written price with options.
Typical timeline
Board and railing repairs usually take a few days. A full rebuild or new deck typically takes one to three weeks, plus any permit time.
