Concrete Patio costs $7.15 to $16.33 per sq ft in New Hampshire in 2026. For a 400 sq ft project, that puts the installed total at $2,858 – $6,533, with most projects landing near $4,696. New Hampshire is about 2% above the national average.
Why New Hampshire prices differ from the national average
Roughly 52% of the installed cost of concrete patio is labor, and labor is the part of the bill that actually moves between states. New Hampshire construction wages average $38.45 per hour against a national figure near $36.97 — a wage index of 1.04×.
Materials behave differently. Ready-mix concrete, rebar, mesh, and forming lumber are priced on national and regional commodity markets, so they barely move from one state to the next. That is why we apply the wage index only to the labor share and hold materials at national prices. Doing that puts New Hampshire at $7.15 to $16.33 per sq ft, against a national baseline of $7.00 to $16.00.
Two other forces sit on top of that. Metro areas inside New Hampshire price above the statewide figure because of wages, permitting, and site access. And the state’s deep frost line adds excavation and below-grade volume that southern states never pay for.
Concrete Patio cost by project size in New Hampshire
These figures apply the New Hampshire rate to common project sizes. They cover a standard specification with normal site access.
| Project size | New Hampshire cost range | Typical |
|---|---|---|
| 10×10 (100 sq ft) | $715 – $1,633 | $1,174 |
| 12×12 (144 sq ft) | $1,029 – $2,352 | $1,690 |
| 12×16 (192 sq ft) | $1,372 – $3,136 | $2,254 |
| 16×20 (320 sq ft) | $2,287 – $5,226 | $3,757 |
| 20×20 (400 sq ft) | $2,858 – $6,533 | $4,696 |
| 24×24 (576 sq ft) | $4,116 – $9,408 | $6,762 |
| 30×40 (1,200 sq ft) | $8,575 – $19,599 | $14,087 |
Where the money actually goes
For a 400 sq ft project in New Hampshire at roughly $4,696, a typical bill splits like this:
| Line item | Share | Cost |
|---|---|---|
| Labor | 52% | $2,442 |
| Materials | 36% | $1,690 |
| Site prep & equipment | 7% | $338 |
| Overhead, disposal & finishing | 5% | $225 |
The labor share is why identical projects diverge so sharply between states. It is also why a bid that comes in far below these numbers usually means a thinner specification or a crew cutting site prep, not a genuine bargain.
Concrete Patio cost by city in New Hampshire
Statewide averages hide a lot. Manchester, Nashua, Concord all price above the New Hampshire average, while rural counties run below it:
| Area | Cost per sq ft | A 400 sq ft project | vs state |
|---|---|---|---|
| Manchester | $7.65 – $17.48 | $5,024 | +7% |
| Nashua | $7.79 – $17.80 | $5,118 | +9% |
| Concord | $7.36 – $16.82 | $4,837 | +3% |
| Rural New Hampshire | $6.65 – $15.19 | $4,367 | −7% |
What is included in a New Hampshire quote — and what is not
A complete quote for this work should list dimensions, specification and grade, site preparation, materials, labor, cleanup, and disposal. Those are the items already reflected in the ranges above.
Costs that usually sit outside the headline number: permits (around $450 in New Hampshire), demolition or removal of existing work, unusual site access, drainage or grading corrections, and any upgrade to the standard specification. When two bids differ by thousands, the gap is nearly always one of these, not the labor rate.

Permits in New Hampshire
A residential permit for work of this type and value in New Hampshire typically runs around $450, though the figure varies by municipality and often scales with declared project value. Permit cost is rarely folded into a contractor’s per-sq ft quote, so add it separately when comparing bids. Confirm requirements with your local building department before work begins — unpermitted work can surface later during a sale or insurance claim.
Best time of year to schedule in New Hampshire
Weather closes the working window in New Hampshire. Concrete and exterior work generally run from late spring through early autumn, and crews book out well before then. Cold-weather work is possible with blankets, heated enclosures, or accelerating admixtures, but those add cost. Booking in late winter for spring work usually secures better pricing than calling in June.
DIY versus hiring a contractor in New Hampshire
Materials account for roughly 48% of the installed price, so a 400 sq ft project carries about $2,254 in materials against an installed cost near $4,696. The gap is labor, equipment, and the risk of getting it wrong.
Because New Hampshire labor runs at 1.04× the national rate, the DIY saving here is closer to the national norm. Weigh it against tool rental, waste disposal, permit responsibility, and the fact that remedial work almost always costs more than doing it right the first time.

Frequently asked questions
How much does concrete patio cost in New Hampshire?
In 2026, concrete patio costs $7.15 to $16.33 per sq ft in New Hampshire. For a 400 sq ft project, the installed total typically lands between $2,858 and $6,533, with most projects near $4,696.
Is concrete patio more expensive in New Hampshire than the national average?
New Hampshire is about 2% above the national average. The driver is a construction wage index of 1.04 times the national figure, applied to the roughly 52% of the project cost that is labor.
Which parts of New Hampshire are most expensive?
Manchester, Nashua, and Concord price above the statewide average because of higher wages, stricter permitting, and tighter site access. Rural counties typically run around 7% below the state figure.
Do I need a permit in New Hampshire?
Most municipalities in New Hampshire require a permit for work of this type and value. Budget around $450 and confirm with your local building department before work starts, since requirements vary between cities and counties.
How deep is the frost line in New Hampshire?
The frost line in New Hampshire is roughly 60 inches. Footings and posts must extend below that depth to avoid frost heave, which adds excavation and material to the job.
When is the cheapest time to book this work in New Hampshire?
Weather closes the working window in New Hampshire. Concrete and exterior work generally run from late spring through early autumn, and crews book out well before then. Cold-weather work is possible with blankets, heated enclosures, or accelerating admixtures, but those add cost. Booking in late winter for spring work usually secures better pricing than calling in June.
How much of the cost is labor versus materials?
Labor is about 52% of the installed price and materials about 48%. That split is why state wage differences move the total so much, and why material price swings move it less than people expect.
Why do contractor quotes in New Hampshire vary so much?
Three things move a quote most: metro versus rural location, site access and preparation, and the specification itself. Two bids are only comparable when both list the same dimensions, the same grade of material, and the same scope of prep work.
