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 Miami, FL average $54,030 a year against a U.S. mean of $65,630 — a factor of 0.823 — 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 $11,917 quote into a $14,896 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.
a pressure-treated deck build in Miami, FL
$11,917 is the typical number, and three bids on the same scope normally land between $9,028 and $18,056.
That is $1,283 less than the same job priced at the national average.
Why the city changes the number
About 55% of this job is labor — $6,554 of the $11,917 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.
Carpenters near Miami average $54,030 a year, against a U.S. mean of $65,630. That is a factor of 0.823, 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 $11,917 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 $9,028 – $18,056, that is not automatically wrong — but it is the question worth asking out loud.
