Siding Repair in Redmond, WA
Siding repair and replacement with the house wrap and flashing done right behind it. When boards crack, swell or pull loose, water has usually been reaching the sheathing for a while. We open the wall, repair what is behind it, add the flashing that was missing and install siding matched to your house, so the repair blends in and the wall stays dry. We serve homeowners across Redmond and nearby Sammamish and Woodinville.

Why siding repair comes up so often in Redmond
Hardboard siding from the 1980s and 90s is common across Grass Lawn, Education Hill and the Sammamish Valley side of Redmond, and it swells and crumbles once water gets past the paint. Cedar lap siding on older homes splits and decays at the bottom courses. Failed boards come off, the sheathing and wrap underneath get checked, and new fiber cement or cedar in a matching profile goes back up. Where siding meets the roof, decks or windows, we add flashing that was often missing originally. Every cut end is sealed and primed so the new siding resists the same moisture.
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.
Siding materials compared
| Siding | Typical life here | Upkeep | Good to know |
|---|---|---|---|
| Fiber cement | 30–50 years | Repaint roughly every 10–15 years | Will not rot, fire-resistant, heavy to install |
| Cedar | 20–30 years with care | Paint or stain every 5–8 years | Beautiful, but needs regular care in our rain |
| Engineered wood | 25–30 years | Repaint roughly every 10 years | Lighter than fiber cement, treated against rot |
| Vinyl | 20–30 years | Wash once a year | Low cost, can crack in cold and fade in sun |

Siding repair in Redmond: cost and timing
Most common causes
Old or torn weather barrier
Felt paper and house wrap wear out, so water that gets past the siding reaches the sheathing.
Unsealed ends and joints
Cut ends and butt joints that were never sealed swell, crack and let water in.
Missing flashing at openings
Windows, doors and roof edges without flashing send water behind the siding.
What drives the price in Redmond
Siding repair in Redmond depends on the material, the size of the area, how much sheathing behind it is damaged, how high the wall is and how many windows and corners need flashing. A section repair is a fraction of the cost of re-siding a wall. You get a written price after the free inspection.
Typical timeline
A small patch is often finished in a day or two. Re-siding one elevation usually takes several days, and a whole house can run from about a week to three weeks.
