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 Gillette, WY average $59,350 a year against a U.S. mean of $65,630 — a factor of 0.904 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for carpenters near Gillette, WY, so this is the Wyoming state average, SOC 47-2031.
  • This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Gillette, WY, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
  • 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 $12,505 quote into a $15,632 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 — $6,878 of the $12,505 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

Carpenters near Gillette average $59,350 a year, against a U.S. mean of $65,630. That is a factor of 0.904, so the labor half is scaled by it and the material half is not.

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 $12,505 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 $9,474 – $18,947, that is not automatically wrong — but it is the question worth asking out loud.
