Notes

  • Where the number comes from. The national price for a siding replacement is $800 per square — installed siding pricing published for 2026, $4–$16 per ft² depending on material. Labor is about 55% of that. Carpenters in Washington average $79,170 a year against a U.S. mean of $65,630 — a factor of 1.206 — so the labor half is scaled by that and the material half is not.
  • What is in the price: tear-off of one layer, house wrap, the siding, J-channel and corner posts, fasteners, disposal and labor.
  • What is not: sheathing replacement found once the old siding is off, insulation added behind the new siding, window and door trim replacement, and permits. These are the lines that turn a $26,723 quote into a $33,404 invoice, so ask about each one before signing.
  • Why state matters more than people expect. Materials ship at national prices; crews do not move. Washington sits above the national mean by 20.6%, which lands on 55% of the job and moves the total by $2,723.
  • Use this as a bid check, not a quote. It prices an average job in an average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

Re-siding 30 squares in Washington

$26,723 is the typical figure, and bids on the same scope normally land between $13,362 and $53,447. That is 30 squares at $891 each.

Why this is not the national number

The same job at the U.S. average comes to $24,000 — this one is $2,723 more.

Carpenters in Washington average $79,170 a year against a U.S. mean of $65,630, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 47-2031. That is about $38 an hour of trade pay, a factor of 1.206.

Labour is 55% of this job; material is the other 45% and it costs the same everywhere. Only the labour half is scaled.

$14,698 of labour, $12,025 of material.

Material is most of the spread

Vinyl sits near the bottom of the range and fibre cement near the top — it costs more per square and it is heavier, slower and harder to cut, so the labour rises with it. Engineered wood sits between them. Any of the three can be a sound choice; what is not sound is comparing a vinyl quote against a fibre cement one as though they were the same job.

The line found after the tear-off

Rotten sheathing. It is invisible until the old siding is off, it is priced per sheet, and on any wall that has been leaking it is the item most likely to move the total. Get the per-sheet price in writing before work starts.

Do the insulation while the walls are open

Adding rigid foam or a rainscreen behind new siding costs a fraction of what it would cost as its own project, and this is the one moment in the building's life when the wall is open. Skipping it is a decision worth making deliberately rather than by default.

Using this against a real bid

Three quotes on identical scope should cluster. One well under $13,362 usually means something was left out rather than found cheaper; one well over $53,447 is a harder job than average, or a crew that does not want the work.
