What Siding Replacement Costs in the Seattle Area
Real 2026 siding costs around Seattle: fiber cement, engineered wood and cedar per square foot, what rot repair adds, and why the flashing behind it matters more than the product.
Siding is the least glamorous large expense in homeownership and one of the most consequential. In a region that delivers rain eight months a year, it is not decoration — it is the system keeping water out of your framing. Here is what replacing it actually costs around Seattle, and where the money goes.
The per-square-foot numbers
- Repair and partial replacement: $3,000–$15,000. Targeted rot repair, failed sections, flashing correction. Worth doing when the rest of the cladding has real life left.
- Fiber cement or engineered wood: $12–$22/sq ft. Full tear-off, weather-resistive barrier, flashing, rain screen where appropriate, new cladding and trim. The regional default.
- Cedar and specialty: $18–$30+/sq ft. Cedar lap or shingle, custom profiles, multi-material elevations.
A typical 2,000 sq ft house therefore lands around $25,000–$50,000. Larger or more complex elevations — multiple gables, tall two-story faces, mixed materials — push higher simply because there is more wall and more trim.
Why siding actually fails here
Almost every failure we tear off traces to water management, not the cladding. Missing or reversed flashing at windows and decks, no drainage plane behind the siding, housewrap lapped the wrong way, penetrations sealed with caulk instead of flashed. The siding gets blamed; the details were the problem.
That is why a quote should describe a system, not a product. Weather barrier, flashing at every opening and penetration, and on most homes a rain screen gap so the wall can dry outward. Our siding page walks through how we build it.
What the tear-off reveals
Removing siding is the only time anyone sees your sheathing. On older homes we routinely find rot at deck ledgers, beneath windows and along the base of walls where grade has crept up. Finding it with the wall open is the cheap version — the same damage discovered later, from the inside, costs far more.
Budget for it the way you would any older-home project: the 10–15% contingency exists precisely for what walls hide.
What it costs by neighborhood stock
The housing tells you what to expect. Everett and Lynnwood are full of 1970s–80s T1-11 and hardboard that is simply finished — straightforward tear-offs, frequent rot at the sill plate. Bellevue’s larger 1980s elevations cost more because there is more wall. Seattle adds character-matching to the equation, and exposed Edmonds and Mukilteo homes weather faster on the water-facing side.
Pair it with the roof if both are due
Roof-to-wall flashing is a shared detail. Doing roofing and siding together means one crew owns that intersection instead of two trades pointing at each other — and it saves a second mobilization and a second round of disruption.

Frequently asked questions
- How much does siding replacement cost in the Seattle area?
- Fiber cement and engineered wood typically run $12–$22 per square foot installed in 2026, including tear-off, weather barrier and flashing. Cedar and specialty profiles run $18–$30+. A typical 2,000 sq ft house lands roughly $25,000–$50,000 depending on cladding, trim complexity and how much rot the tear-off finds.
- What is the best siding for Washington's climate?
- Fiber cement is the regional default — dimensionally stable, fire-resistant and it holds paint through our wet-dry cycling. Engineered wood gives a warmer look with easier handling. What matters more than the product is what sits behind it: weather barrier, flashing at every penetration, and a drainage gap.
- How much does rot repair add to a siding job?
- It varies with what the tear-off reveals. Isolated repair around a window or deck ledger might add $1,000–$4,000; widespread sill-plate or sheathing rot can add $10,000 or more. An honest contractor quotes the visible scope and carries a contingency rather than quoting low and issuing change orders.
- Is a rain screen worth the extra cost?
- In this climate, on most homes, yes. The drainage gap lets the wall assembly dry outward instead of holding moisture against the sheathing, and it is the single biggest factor in whether siding lasts decades or fails early. It adds modestly to the job and materially to its life.
