If you are planning more than one job in Arizona
The table prices neighboring jobs at their usual sizes using statewide Arizona wages and prices. Against national midpoints, concrete patio comes out highest (−1%) and gutters lowest (−7%), because each job leans on different trades.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Wood deck | 300 sq ft | $7,250 – $14,600 | −4% |
| Concrete patio | 300 sq ft | $1,200 – $3,950 | −1% |
| Paver patio | 300 sq ft | $2,900 – $5,300 | −3% |
| Gutters | 160 linear ft | $1,150 – $3,900 | −7% |
Extras that change the Arizona total
Extras are quoted nationally and then scaled to Arizona by the average of the local wage index (0.97) and goods index (0.95), a factor of 0.96. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.
| Add-on | Local range |
|---|---|
| Add a deck railing (approx. 0.3 ft per sq ft) | $1,750 – $5,200 |
Arizona against its neighbors
Arizona ranks 29 of 51 (the 50 states plus DC) for composite deck, where 1 is the most expensive. The costliest is Hawaii at $23,800 and the cheapest Oklahoma at $15,300, both for 300 sq ft at the midpoint. Arizona sits at $17,500. The five states closest by workforce center are listed below.
| State | Distance | Range | Midpoint | vs. here |
|---|---|---|---|---|
| Nevada | 340 miles away | $12,100 – $24,200 | $18,200 | +4% |
| New Mexico | 340 miles away | $11,500 – $23,100 | $17,300 | −1% |

When Arizona weather lets you build
Season matters for composite deck. For each Arizona metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.
Prescott Valley has the longest comfortable season of the metros we cover in Arizona at 11 months (August through June); Yuma has the shortest at 6 (November through April). Rainfall runs from 3 inches a year in Yuma to 21 inches in Flagstaff.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Phoenix | 44 | 104 | 9 | 7: October through April |
| Tucson | 41 | 100 | 11 | 7: October through April |
| Prescott Valley | 26 | 90 | 13 | 11: August through June |
| Yuma | 48 | 107 | 3 | 6: November through April |
| Flagstaff | 18 | 82 | 21 | 10: February through November |
| Lake Havasu City | 43 | 109 | 4 | 7: October through April |
Composite deck cost by metro in Arizona
1 of the 6 metros sit above the statewide midpoint of $17,500, and the top-to-bottom gap is 13%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (300 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Phoenix, AZ | $11,800 – $23,600 | $17,700 | +1% |
| Prescott Valley, AZ | $11,500 – $23,000 | $17,200 | −1% |
| Flagstaff, AZ | $11,400 – $22,900 | $17,100 | −2% |
| Tucson, AZ | $10,700 – $21,500 | $16,100 | −8% |
| Yuma, AZ | $10,500 – $21,100 | $15,800 | −9% |
| Lake Havasu City, AZ | $10,500 – $21,000 | $15,700 | −10% |
Composite deck: what moves the price in Arizona
Board grade
Composite materials run $16-$32 per sq ft and the installed price is $40-$80 per sq ft, including the substructure (HomeGuide).
Labor
Labor for composite is $24-$48 per sq ft, higher than wood because the boards need extra parts and more careful assembly.
Drainage
Ground-level decks over poorly draining yards may need $1,000-$4,000 of drainage work first.
Engineering
Large or complex decks may need a structural engineer at $100-$220 an hour to get a permit.
Quality levels and sizes in Arizona
The cited range is cut into three overlapping bands (basic, standard and premium) and scaled to statewide Arizona wages and prices. The grid prices the same bands at 4 common sizes.

Arizona labor market for composite deck
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 2 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.97 for Arizona.
For carpenters (47-2031, weighted 80%) the local median is $28.17 an hour, which is 3% below the national $29.12. The middle half of them earn between $23.02 and $33.57 an hour. BLS counts 16,230 of them working in the state, 50.1 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
Construction laborers (47-2061), 20% of the weighting: a median of $22.40 an hour, in line with the US median of $22.66. The middle half of them earn between $19.04 and $24.82 an hour. About 37,630 work in the state. That is 116.2 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
A crew paid at the 75th percentile for carpenters ($33.57 an hour) would add about $1,600 to the statewide midpoint; one at the 25th percentile ($23.02) would take off about $1,550. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 3,239,430 jobs across Arizona (May 2025), which is 2.1% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $23.02 | $28.17 | $33.57 | $29.12 | 0.97 | state |
| Construction laborers (47-2061) | 20% | $19.04 | $22.40 | $24.82 | $22.66 | 0.99 | state |
