When Rhode Island weather lets you build
Weather decides when digging and ground work can happen, and Rhode Island is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.
Providence has 8 comfortable months (April through November), with about 48 inches of precipitation a year.
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 |
|---|---|---|---|---|
| Providence | 22 | 84 | 48 | 8: April through November |
Related projects, priced for Rhode Island
Each project weights the trades differently, so Rhode Island's wage level does not push every price by the same amount. Compared with the US midpoint, roof replacement is +7% and kitchen remodel −2%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Kitchen remodel | 120 sq ft | $18,200 – $31,000 | −2% |
| Bathroom remodel | 45 sq ft | $4,650 – $23,100 | −1% |
| Detached garage | 576 sq ft | $29,800 – $59,900 | +3% |
| Roof replacement | 2,000 sq ft of roof | $6,600 – $13,300 | +7% |
Rhode Island labor market for home addition
Rhode Island's labor line is priced from 6 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 1.04 times the national level.
Carpenters (47-2031), 50% of the weighting: a median of $29.25 an hour, in line with the US median of $29.12. The middle half of them earn between $25.14 and $36.42 an hour. About 2,580 work in the state. That is 51.5 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $30.26 an hour, 10% above the US median of $27.41. The middle half of them earn between $28.69 and $35.39 an hour. About 250 work in the state. That is 5.0 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $35.62 an hour, which is 17% above the national $30.38. The middle half of them earn between $28.08 and $46.01 an hour. BLS counts 2,420 of them working in the state, 48.3 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $36.77 an hour, 20% above the US median of $30.67. The middle half of them earn between $28.24 and $51.61 an hour. About 1,820 work in the state. That is 36.3 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $22.65 an hour, which is 20% below the national $28.33. The middle half of them earn between $20.01 and $35.13 an hour. BLS counts 440 of them working in the state, 8.8 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $29.63 an hour, 11% above the US median of $26.65. The middle half of them earn between $23.72 and $36.81 an hour. About 360 work in the state. That is 7.2 per 10,000 jobs, compared with 8.7 nationally, so expect fewer local crews to bid.
A crew paid at the 75th percentile for carpenters ($36.42 an hour) would add about $4,700 to the statewide midpoint; one at the 25th percentile ($25.14) would take off about $2,700. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 501,340 jobs across Rhode Island (May 2025), which is 0.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
