How much will new siding cost?
Pick your project, home size and material to see a 2026 price range for the Seattle area, from a small section repair to re-siding the whole house.
What changes the cost of siding around Seattle
Wall area
Square footage of wall drives most of the price. Gables, bump-outs and many corners add trim and labor.
Material
LP SmartSide and Hardie lap are the most common. Hardie panel and cedar cost more, and cedar needs more upkeep.
Windows and doors
Each opening gets new trim, a sill pan and flashing tape. Homes with many windows cost more per square foot.
Height and access
Two- and three-story walls need ladders, staging or scaffolding, and more time per square foot.
Finish
Factory-finished ColorPlus skips the painting step. Primed boards cost less now but need painting soon after.
What is behind it
Wet sheathing, rotted studs and missing flashing are common on older Northwest homes and add cost once the wall is open.
Do you need new siding or just a repair?
A section repair is enough
- Damage is limited to one area or a few boards
- The house wrap behind it is intact
- Your siding profile is still available or can be matched
- Other walls show no swelling, stains or soft spots
Time to re-side
- Several walls swell, crack or feel soft
- There is no house wrap or flashing behind the siding
- Paint fails on most walls every few years
- Your siding is discontinued or you want a new look

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 |
