Add-ons priced for Michigan
Extras are quoted nationally and then scaled to Michigan by the average of the local wage index (1.03) and goods index (0.96), a factor of 0.99. 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 a deck railing (approx. 0.3 ft per sq ft) | $1,800 – $5,350 |
Which Michigan city is cheapest for composite deck?
4 of the 10 metros sit above the statewide midpoint of $18,100, and the top-to-bottom gap is 21%. 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.

|---|---|---|---|
| Detroit, MI | $12,800 – $25,700 | $19,200 | +6% |

Composite deck: what moves the price in Michigan
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.
How Michigan compares with nearby states
Michigan ranks 24 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. Michigan sits at $18,100. The five states closest by workforce center are listed below.

What carpenters and the other trades earn in Michigan
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 1.03 for Michigan.
For carpenters (47-2031, weighted 80%) the local median is $29.66 an hour, which is in line with the national $29.12. The middle half of them earn between $23.80 and $35.09 an hour. BLS counts 18,590 of them working in the state, 42.2 for every 10,000 jobs (US: 43.1), so the local bench is about average.
Construction laborers (47-2061), 20% of the weighting: a median of $23.84 an hour, 5% above the US median of $22.66. The middle half of them earn between $21.52 and $29.68 an hour. About 28,490 work in the state. That is 64.7 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
A crew paid at the 75th percentile for carpenters ($35.09 an hour) would add about $1,600 to the statewide midpoint; one at the 25th percentile ($23.80) would take off about $1,750. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 4,403,730 jobs across Michigan (May 2025), which is 2.8% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $23.80 | $29.66 | $35.09 | $29.12 | 1.02 | state |
| Construction laborers (47-2061) | 20% | $21.52 | $23.84 | $29.68 | $22.66 | 1.05 | state |

Weather windows across Michigan
Season matters for composite deck. For each Michigan metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.
Detroit has the longest comfortable season of the metros we cover in Michigan at 9 months (March through November); Muskegon has the shortest at 8 (April through November). Rainfall runs from 29 inches a year in Traverse City to 42 inches in Niles.
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.
