If you are planning more than one job in New Hampshire
Each project weights the trades differently, so New Hampshire's wage level does not push every price by the same amount. Compared with the US midpoint, asphalt driveway is +3% and stamped concrete −1%.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Concrete driveway | 600 sq ft | $3,650 – $9,150 | level |
| Concrete patio | 300 sq ft | $1,250 – $4,000 | level |
| Detached garage | 576 sq ft | $29,000 – $58,200 | level |
| Stamped concrete | 400 sq ft | $3,200 – $7,900 | −1% |
| Asphalt driveway | 600 sq ft | $3,100 – $7,650 | +3% |
| Gravel driveway | 1,000 sq ft | $2,550 – $10,400 | +2% |
Wages behind the New Hampshire number
New Hampshire's labor line is priced from 4 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 1.00 times the national level.
Cement masons and concrete finishers (47-2051), 50% of the weighting: a median of $26.06 an hour, 5% below the US median of $27.41. The middle half of them earn between $23.26 and $31.63 an hour. About 300 work in the state. That is 4.4 per 10,000 jobs, compared with 13.3 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 30%) the local median is $24.03 an hour, which is 6% above the national $22.66. The middle half of them earn between $21.61 and $28.32 an hour. BLS counts 4,330 of them working in the state, 63.4 for every 10,000 jobs (US: 70.5), so the local bench is about average.
Operating engineers and other construction equipment operators (47-2073), 10% of the weighting: a median of $29.91 an hour, 4% above the US median of $28.78. The middle half of them earn between $27.55 and $35.51 an hour. About 1,330 work in the state. That is 19.5 per 10,000 jobs, compared with 30.7 nationally, so expect fewer local crews to bid.
Carpenters (47-2031), 10% of the weighting: a median of $29.42 an hour, in line with the US median of $29.12. The middle half of them earn between $24.12 and $35.46 an hour. About 3,760 work in the state. That is 55.0 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
A crew paid at the 75th percentile for cement masons and concrete finishers ($31.63 an hour) would add about $160 to the statewide midpoint; one at the 25th percentile ($23.26) would take off about $80. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 683,290 jobs across New Hampshire (May 2025), which is 0.4% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

When New Hampshire weather lets you pour
Weather decides when pouring concrete can happen, and New Hampshire 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.
Manchester has 6 comfortable months (May through October), with about 40 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 |
|---|---|---|---|---|
| Manchester | 17 | 84 | 40 | 6: May through October |
Extras that change the New Hampshire total
Add-ons start from national price ranges and are scaled by 0.99 for New Hampshire, which is the average of the area's wage index (1.00) and goods price index (0.99). The estimator above can add them to your total.
| Add-on | Local range |
|---|---|
| Add rebar reinforcement | $400 – $1,200 |
| Remove old concrete first | $790 – $2,400 |
How New Hampshire compares with nearby states
New Hampshire ranks 25 of 51 (the 50 states plus DC) for concrete slab, where 1 is the most expensive. The costliest is Hawaii at $5,150 and the cheapest Arkansas at $3,350, both for 400 sq ft at the midpoint. New Hampshire sits at $3,800. The five states closest by workforce center are listed below.
| State | Distance | Range | Midpoint | vs. here |
|---|---|---|---|---|
| Massachusetts | 40 miles away | $2,700 – $5,600 | $4,150 | +9% |
| Rhode Island | 90 miles away | $2,550 – $5,400 | $3,950 | +4% |

Why two New Hampshire quotes can differ
Thickness and mix
A 4-inch slab uses about 1.23 cubic yards of concrete per 100 sq ft; a 6-inch slab uses about 1.85. Stepping up from a 3,000 PSI to a 4,000-4,500 PSI mix adds $10-$40 per cubic yard (Estimators.us).
Base and reinforcement
A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.
Truck and pump access
If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.
Small-job minimums
Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.
Finish
A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.
New Hampshire metro-by-metro prices
New Hampshire has one metro in our dataset, Manchester, so the statewide and metro figures are close. The state figure uses BLS statewide wages, which include rural areas. 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 (400 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Manchester, NH | $2,450 – $5,150 | $3,800 | level |
