Maine seasons and wood deck
Season matters for wood deck. For each Maine metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.
Every Maine metro on the list has 8 comfortable months, though rainfall ranges from 42 inches a year in Bangor to 48 in Portland.
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 |
|---|---|---|---|---|
| Portland | 16 | 80 | 48 | 8: April through November |
| Bangor | 9 | 80 | 42 | 8: April through November |
Maine against its neighbors

Wood deck: what moves the price in Maine
Wood species
Pressure-treated pine is the cheapest at $25-$50 per sq ft installed. Ipe runs $50-$70 and bamboo $27-$52 (HomeGuide).
Height and stairs
A second-story deck needs more structure. New stairs run $1,400-$2,600 installed.
Railing
A wood or vinyl railing adds $20-$60 per linear foot.
Replacement versus new
Deck replacement costs $30-$55 per sq ft because of demolition and haul-away.
Permit
Deck permits average $50-$150. Many cities skip the permit for small, low, freestanding decks.
Maine labor market for wood 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 1.02 for Maine.
For carpenters (47-2031, weighted 80%) the local median is $29.88 an hour, which is in line with the national $29.12. The middle half of them earn between $25.46 and $35.00 an hour. BLS counts 5,170 of them working in the state, 80.7 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 $22.32 an hour, in line with the US median of $22.66. The middle half of them earn between $19.51 and $25.51 an hour. About 3,960 work in the state. That is 61.8 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 ($35.00 an hour) would add about $700 to the statewide midpoint; one at the 25th percentile ($25.46) would take off about $600. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 640,610 jobs across Maine (May 2025), which is 0.4% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $25.46 | $29.88 | $35.00 | $29.12 | 1.03 | state |
| Construction laborers (47-2061) | 20% | $19.51 | $22.32 | $25.51 | $22.66 | 0.98 | state |
| Blended | 100% | 1.02 | |||||
Maine metro-by-metro prices
1 of the 2 metros sit above the statewide midpoint of $11,300, and the top-to-bottom gap is 5%. 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 |
|---|---|---|---|
| Portland, ME | $7,600 – $15,300 | $11,400 | +2% |
| Bangor, ME | $7,250 – $14,500 | $10,900 | −3% |
Extras that change the Maine total
Extras are quoted nationally and then scaled to Maine by the average of the local wage index (1.02) and goods index (0.97), 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-on | Local range |
|---|---|
| Add stairs (flat) | $1,400 – $2,600 |
Other Maine jobs that often go with wood deck
The table prices neighboring jobs at their usual sizes using statewide Maine wages and prices. Against national midpoints, composite deck comes out highest (level) and paver patio lowest (−5%), because each job leans on different trades.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Composite deck | 300 sq ft | $12,000 – $24,100 | level |
| Concrete patio | 300 sq ft | $1,200 – $3,900 | −2% |
| Paver patio | 300 sq ft | $2,850 – $5,150 | −5% |
| Detached garage | 576 sq ft | $28,800 – $57,700 | −1% |
