Composite deck: what moves the price in North Dakota
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.
Add-ons priced for North Dakota
Extras are quoted nationally and then scaled to North Dakota by the average of the local wage index (0.97) and goods index (0.96), 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 |
Related projects, priced for North Dakota
The table prices neighboring jobs at their usual sizes using statewide North Dakota wages and prices. Against national midpoints, paver patio comes out highest (+5%) and wood deck lowest (−4%), 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 | −2% |
| Paver patio | 300 sq ft | $3,150 – $5,700 | +5% |
| Gutters | 160 linear ft | $1,300 – $4,150 | −1% |
Composite deck cost by metro in North Dakota
1 of the 2 metros sit above the statewide midpoint of $17,500, and the top-to-bottom gap is 3%. 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 |
|---|---|---|---|
| Fargo, ND | $11,700 – $23,500 | $17,600 | +1% |
| Bismarck, ND | $11,400 – $22,800 | $17,100 | −2% |
North Dakota seasons and composite deck
Season matters for composite deck. For each North Dakota metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.
Every North Dakota metro on the list has 7 comfortable months, though rainfall ranges from 19 inches a year in Bismarck to 24 in Fargo.
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 |
|---|---|---|---|---|
| Fargo | 0 | 82 | 24 | 7: April through October |
| Bismarck | 2 | 85 | 19 | 7: April through October |
What carpenters and the other trades earn in North Dakota
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 North Dakota.
For carpenters (47-2031, weighted 80%) the local median is $27.83 an hour, which is 4% below the national $29.12. The middle half of them earn between $23.47 and $30.55 an hour. BLS counts 2,360 of them working in the state, 55.0 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 $23.59 an hour, 4% above the US median of $22.66. The middle half of them earn between $21.96 and $29.17 an hour. About 5,050 work in the state. That is 117.6 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 ($30.55 an hour) would add about $810 to the statewide midpoint; one at the 25th percentile ($23.47) would take off about $1,300. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 429,430 jobs across North Dakota (May 2025), which is 0.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $23.47 | $27.83 | $30.55 | $29.12 | 0.96 | state |
| Construction laborers (47-2061) | 20% | $21.96 | $23.59 | $29.17 | $22.66 | 1.04 | state |
