Siding Repair in Bothell, 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 Bothell and nearby Kenmore and Woodinville.

Why siding repair comes up so often in Bothell
Hardboard lap siding was common in Bothell subdivisions built in the 80s and 90s, and by now many homes show swollen bottom edges, flaking paint and soft spots around windows. Fiber cement on newer homes fails mostly at flashing and trim joints. We replace damaged hardboard with matching material or upgrade to fiber cement, install house wrap and flashing behind it, and correct clearances at grade and roof lines so the new siding lasts in Bothell’s wet climate.
Bothell has a small historic core around Main Street with older homes from the early 1900s, but most houses here date from the 1970s through the 2000s. North of I-405, Canyon Park, North Creek, Thrasher’s Corner and the Queensborough area are full of two-story subdivision homes with hardboard or fiber cement siding, attached decks and builder-grade trim. Westhill and Maywood have more 60s and 70s split-levels and ramblers on wooded lots. Many homes have tight side yards and backyards that slope toward greenbelts. Newer townhomes and apartments are concentrated near downtown, Canyon Park and the North Creek business parks.
Bothell sits in the Sammamish River and North Creek valleys, with hills rising on both sides. The valleys hold fog and damp air on winter mornings, while the hillsides have heavy tree cover and greenbelts that keep walls and decks shaded. Tight lot spacing in many subdivisions means side walls rarely dry out. Long, wet winters soften hardboard siding and trim, and builder-grade flashing from the 80s and 90s is reaching the end of its useful life.
Our crew comes out from our Woodinville office, and we also work in nearby Kenmore, Woodinville, Mill Creek and Lynnwood.

Neighborhoods and permits in Bothell
Canyon Park and North Creek on the Snohomish County side have big 80s and 90s subdivisions where hardboard siding and nailed decks are aging out. Westhill and Maywood, south of downtown, are hillier and older, with mature trees and shaded lots. Homes near the Sammamish River and in the valley get more fog and dampness. Thrasher’s Corner and Queensborough have newer homes on tighter lots, often backing onto greenbelts with heavy shade.
Small like-for-like repairs often don’t need a permit, but structural work, new decks and larger replacements usually do. Permits come from the City of Bothell for homes in both the King County and Snohomish County parts of the city. We check with the City of Bothell before starting so your project is handled correctly.

| 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 Bothell: cost and timing
Most common causes
No clearance at the bottom
Siding that touches soil, mulch, roofs or decks soaks up water at the bottom edge.
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.
What drives the price in Bothell
Siding repair in Bothell 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.
