What we see with siding repair in Bothell
Across Bothell, where you find 1980s–2000s subdivisions with fiber cement or hardboard siding and attached decks, siding fails first where hillside lots and tight side yards keep some walls shaded and wet, and builder-grade flashing from the 80s and 90s is reaching the end of its life. The bottom courses and the boards around windows and decks take the most water.
Bothell sits in two counties; we cover both sides. We regularly work in Canyon Park, North Creek, Thrasher’s Corner, Maywood, Westhill and Queensborough.
Bothell straddles King and Snohomish counties along North Creek and the Sammamish River, with many homes on hillside lots. 1980s–2000s subdivisions in Canyon Park, North Creek and Thrasher’s Corner, and older homes near downtown.

Siding options for Bothell homes
Fiber cement (James Hardie)
HardiePlank lap, shingle and panel siding. Will not rot, resists fire and pests, and holds paint well. The most common choice for our climate.
Western red cedar
Natural wood lap, bevel or shingles. Beautiful and traditional, but needs regular paint or stain to last.
Engineered wood (LP SmartSide)
Treated wood-strand siding that is lighter than fiber cement and comes in long lengths.
Board and batten
Vertical panels with battens over the seams, in fiber cement or wood, popular on modern farmhouse and accent walls.
Siding in Bothell
Bothell straddles King and Snohomish counties along North Creek and the Sammamish River, with many homes on hillside lots.
Typical homes: 1980s–2000s subdivisions in Canyon Park, North Creek and Thrasher’s Corner, and older homes near downtown.
Many Bothell homes have hardboard siding from the 80s and 90s that is now swelling and is a good candidate for fiber cement.
We regularly work near Canyon Park, the Sammamish River Trail, downtown Main Street and North Creek.
Repair or full replacement?
Section repair
Damage is local, the barrier behind it is sound, and the siding can be matched. Common at roof lines, windows and the bottom courses.
Full wall
One wall takes most of the weather or has failed throughout. We strip and re-side the wall so it all matches.
Whole house
Siding has reached the end of its life, is a discontinued product like old hardboard, or you want a new look and full new barrier.
We open a small area first to check the barrier and sheathing, then tell you which option fits.
Fiber cement installed the way it should be
- About 6 inches of clearance above soil and mulch, and 1–2 inches above roofs and decks
- Kick-out flashing wherever a roof edge meets a wall
- Flashing behind every butt joint
- Primed and sealed cut ends
- Head flashing over windows and doors, sill pans under them
- Weather barrier lapped shingle-style, with taped seams around openings
- Correct nailing, never face-nailed too tight
Most fiber cement failures we see are installation problems, not product problems. Getting these details right is what makes a siding job last.
Paint and color
Fiber cement can come factory-painted (James Hardie ColorPlus) or primed and painted on site. Factory finish is very durable; field paint lets you match any color exactly and touch up easily. For repairs we match your existing color so the new section blends in.
Siding Repair & Replacement in Bothell: what you should know
Siding is the outer shell that sheds most of the rain, but it is not the only waterproofing. Behind it are the weather barrier and flashing that catch the water that gets past. In Bothell, we see siding fail where those layers were skipped or have worn out, and where boards sit too close to the ground, decks or roofs. A good siding repair fixes the surface and the details behind it.
What causes it in Bothell
No clearance at grade
Fiber cement needs about 6 inches above soil and mulch, and around 2 inches above roofs and decks. Buried edges swell, flake and rot the wall behind them.
Unsealed cut ends and butt joints
Fiber cement cut edges must be primed and joints flashed. Without that, water wicks in and the planks swell.
Worn-out weather barrier
Older felt or torn house wrap lets water reach the sheathing, especially at seams and around openings.
Paint failure
Once paint cracks and peels, wood siding takes on water and fiber cement edges start to break down.
What our siding repair includes
- Inspection of the siding, barrier and sheathing behind it
- Removal of damaged siding and trim
- Sheathing repair where the wall is soft
- New weather barrier lapped into the existing barrier
- Flashing at windows, doors, roof lines and penetrations
- New siding matched to profile, exposure and texture
- Primer and paint matched to your house, or factory-finished siding
How to prevent it
- Keep landscaping and mulch below the bottom course
- Repaint before paint fails, and touch up chips at cut edges
- Clean siding gently once a year to remove moss and mildew
- Fix gutter overflow so water does not sheet down the wall
- Have flashing checked whenever you replace a roof or add a deck
What affects the cost in Bothell
Siding cost depends on the material (fiber cement, cedar or engineered wood), the size of the area, how many windows and corners it includes, and whether the sheathing behind it is sound. A section repair costs far less than a full wall, and a full wall far less than a whole house. We tell you which one you need after opening the area and checking the barrier.
How long it takes
A section repair usually takes one to two days. A full wall takes two to four days, and a whole-house re-side typically takes one to three weeks depending on size, trim details and weather.
