Notes

  • Where the number comes from. The national price for a pressure-treated deck build is $33 per ft² of deck — pressure-treated deck pricing published for 2026, $25–$50 per ft² installed. Labor is about 55% of that. Carpenters near Federal Way, WA average $84,060 a year against a U.S. mean of $65,630 — a factor of 1.281 — so the labor half is scaled by that and the material half is not.

  • Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
  • What is in the price: footings, framing, pressure-treated decking, fasteners, a code-compliant railing, and labor.
  • What is not: stairs beyond two steps, permits, ledger repair on the house, and any grading work. These are the lines that turn a $7,315 quote into a $9,143 invoice, so ask about each one before signing.
  • Use this as a bid check, not a quote. It prices an average job in 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.

Why the city changes the number

About 55% of this job is labor — $4,023 of the $7,315 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

What the quote should include

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $7,315 and something a quarter higher.

Use it as a bid check, not a quote

This prices an average job in average condition. 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 national average.

If a bid lands outside $5,541 – $11,083, that is not automatically wrong — but it is the question worth asking out loud.
