Estimate Concrete Prices Across New Hampshire
Use this Concrete Cost in New Hampshire calculator to estimate 2026 concrete budgets for slabs, patios, driveways, garage floors and ready-mix orders. Calculate cubic yards from dimensions, add a waste allowance, enter your local NH ready-mix quote, compare installed price ranges and check contractor bids on a cost-per-square-foot basis. All figures are planning estimates—final New Hampshire concrete prices depend on supplier location, mix design, project access, site preparation, reinforcement, finish, labor, delivery distance, season and local permit requirements.
Estimate installed slab cost, model a ready-mix order, calculate material cost from dimensions and waste, or compare contractor quotes by total price and effective cost per square foot.

Compare scope as well as price: thickness, base preparation, reinforcement, finish, joints, sealer, demolition, pumping, cleanup, permit responsibility and warranty may differ.
There is no single official concrete price for the entire state. A garage slab in Manchester, a driveway in Nashua, a patio in Concord, a foundation pour in Keene and a rural project in the North Country may all have different costs. Ready-mix plants serve different delivery territories, contractors face different travel and equipment needs, and jobsite access can change the crew and equipment required even when the finished square footage is the same.
For a first-pass 2026 budget, current national guidance from Concrete Network places ready-mix concrete around $160 to $195 or more per cubic yard, with a reported 2025 ready-mix average near $179.95 per yard. HomeGuide's current slab guide places a standard installed concrete slab around $6 to $12 per square foot. Those ranges are useful as benchmarks, not New Hampshire price guarantees.
New Hampshire's major ready-mix companies reinforce why local quotes matter. Redimix Companies states that it is a leading concrete supplier in New Hampshire and operates multiple facilities across NH and southern Maine, while Carroll Concrete operates numerous ready-mix plants across New Hampshire and Vermont. Both emphasize quote-based service rather than one public statewide price. The calculator therefore uses editable price fields so you can replace the default with the quote that actually applies to your project.
Project type can matter as much as the concrete itself. A plain interior slab can have a simpler finish and access plan than an exterior driveway, while a stamped patio can require several additional finishing steps. The ranges below are broad 2026 budgeting values based on current national guides; actual New Hampshire bids can fall outside them.
| Concrete Project | 2026 Planning Range | Main Cost Drivers | New Hampshire Considerations |
|---|---|---|---|
| Ready-mix concrete | $160–$195+ per yd³ | PSI, additives, order size, distance | Use a current quote from a plant serving your delivery area. |
| Basic concrete slab | $6–$12 per ft² | Thickness, base, forms, finishing | Exterior work may need more preparation than a simple interior slab. |
| Plain concrete patio | $4–$12 per ft² | Excavation, base, access, finish | Drainage and freeze-thaw exposure matter for exterior flatwork. |
| Broom-finish patio | $6–$13 per ft² | Finish, edges, joints, prep | Broom finish is commonly selected for exterior traction. |
| Concrete driveway | $8–$20 per ft² | Thickness, steel, removal, grading | Vehicle loads and winter exposure can make scope more demanding. |
| Stamped concrete | $9–$22+ per ft² | Patterns, colors, borders, sealer | Complex multi-color work can exceed basic decorative ranges. |
| Exposed aggregate | $7–$18 per ft² | Aggregate, exposure process, labor | Decorative finish adds labor compared with plain flatwork. |
| Heavier reinforced slab | $8–$14+ per ft² | Thickness, reinforcement, preparation | Structural or vehicle-use slabs may require engineering or a more detailed scope. |
Do not treat the table as a contractor rate sheet. A project with simple machine access, no demolition and an easy stone base can price very differently from a project that requires hand excavation, pumping, retaining edges or restoration. The correct comparison is between complete written scopes.
Ready-mix is normally sold by volume, but the per-yard number is only the starting point. A supplier quote may also include delivery-zone charges, small-load or minimum-order fees, fuel adjustments, waiting time, winter-related charges, special admixtures, fiber reinforcement, color, accelerated set or pumping. The exact billing structure varies by supplier.
Redimix Companies and Carroll Concrete both operate extensive New Hampshire ready-mix networks, but their public home pages direct customers toward quote or service inquiries rather than presenting one price that applies statewide. This is useful for planning: supplier distance and plant coverage matter, so a quote for Manchester should not automatically be used for a project near Lebanon, Portsmouth or Berlin.
Enter the written supplier quote into the calculator above for the most useful result.
For a rectangular slab, calculate volume before estimating price. Multiply length by width to get square feet, convert thickness in inches to feet by dividing by 12, multiply to obtain cubic feet and divide by 27 because one cubic yard contains 27 cubic feet.
Example: 20 ft × 20 ft × 4 in ÷ 12 ÷ 27 ≈ 4.94 yd³ before waste.
The calculator lets you add a 0%, 5%, 10% or 15% allowance. The correct allowance depends on form accuracy, excavation, subgrade variation and jobsite conditions. A waste factor should not be used to hide bad measurements; it is simply a planning cushion for real-world uncertainty.
These examples use a 4-inch slab, a 10% volume allowance and a planning ready-mix price of $180 per cubic yard. They show the concrete-material portion only before delivery fees, base stone, reinforcement, forms, labor, finishing, pumping, demolition, permits or contractor overhead.
| Slab Size | Area | Base yd³ at 4 in | yd³ + 10% | Concrete at $180/yd³ |
|---|---|---|---|---|
| 10 × 10 ft | 100 ft² | 1.23 yd³ | 1.36 yd³ | About $244 |
| 12 × 12 ft | 144 ft² | 1.78 yd³ | 1.96 yd³ | About $352 |
| 12 × 20 ft | 240 ft² | 2.96 yd³ | 3.26 yd³ | About $587 |
| 16 × 20 ft | 320 ft² | 3.95 yd³ | 4.35 yd³ | About $782 |
| 20 × 20 ft | 400 ft² | 4.94 yd³ | 5.43 yd³ | About $978 |
| 20 × 24 ft | 480 ft² | 5.93 yd³ | 6.52 yd³ | About $1,174 |
| 24 × 24 ft | 576 ft² | 7.11 yd³ | 7.82 yd³ | About $1,408 |
| 24 × 30 ft | 720 ft² | 8.89 yd³ | 9.78 yd³ | About $1,760 |
| 30 × 30 ft | 900 ft² | 11.11 yd³ | 12.22 yd³ | About $2,200 |
| 30 × 40 ft | 1,200 ft² | 14.81 yd³ | 16.30 yd³ | About $2,933 |
Small pours can carry high effective per-yard costs when minimum delivery or short-load charges are added.
A 6-inch slab uses 50% more concrete than a 4-inch slab of the same length and width.
Rebar, mesh, fibers and thickened edges can materially change both material and labor cost.
Long placement distances, steep sites and limited truck access may require extra labor or a pump.
Broom, exposed aggregate, stamping, coloring and specialty sealers add different levels of labor.
New Hampshire exterior concrete is exposed to winter conditions, so mix selection, drainage, base preparation, curing and jointing deserve attention. A low quote that omits necessary preparation can be more expensive in the long run if the slab moves, scales or cracks prematurely. Ask how the contractor addresses the specific exposure and use conditions for the driveway, walkway, patio or slab.
Concrete price can change with compressive strength, air entrainment, fibers, accelerators, retarders, hot water, integral color and other mix adjustments. The correct mix should match the plans, engineer requirements, local code and exposure—not simply the lowest advertised price per cubic yard.
New Hampshire lots can range from compact suburban sites to sloped or rocky rural properties. Excavation depth, ledge or large stone, subgrade stability, drainage and haul-off can all affect the final price. Make sure a bid explains who is responsible for excavation, stone base, compaction and disposal.
The ready-mix truck is only one part of the finished project. Preparation, reinforcement, labor, access and seasonal conditions can all influence total cost.
New Hampshire is small geographically compared with many states, but concrete pricing still varies by delivery territory and project conditions. Plant proximity can matter because ready-mix is time-sensitive, and contractor travel can affect labor and equipment mobilization. A project close to a plant or contractor yard may have a different cost structure from a remote or difficult-to-access site.
Large local market with nearby ready-mix infrastructure. Compare supplier delivery terms and contractor scope rather than using a statewide average alone.
Southern NH access can be favorable, but demolition, driveway logistics and residential site constraints still affect installed cost.
Central location does not eliminate project-specific factors such as base work, access, reinforcement and finish.
Site access, traffic, tighter lots and coastal project conditions can change logistics and contractor pricing.
Travel distance and plant coverage may influence delivery cost. Use supplier quotes tied to the exact address.
Regional ready-mix networks serve the area, but rural access, pumping and winter scheduling can affect project budgets.
Seasonal access, terrain and restoration around finished properties can matter as much as the concrete material price.
Longer travel distances and fewer nearby alternatives can make delivery planning especially important.
Suburban driveway, patio and slab work should be compared on total scope, including removal, base and reinforcement.
Redimix Companies says it is a leading supplier in New Hampshire and southern Maine and identifies seven facilities across that service region. Carroll Concrete states that it operates numerous ready-mix plants across New Hampshire and Vermont. These networks improve coverage, but each job still needs a plant-specific quote because haul distance, order size, mix specification and delivery timing can affect the delivered price.
When requesting a quote, provide the job address, approximate yardage, required PSI or specified mix, preferred pour date, estimated discharge time and whether a pump will be used. Ask how the supplier handles short loads, waiting time, cancellations, returned concrete, winter materials and weekend deliveries.
Concrete pricing can be affected by code-required structural details, inspection requirements and permits. As of July 1, 2026, the New Hampshire Division of Fire Safety lists the updated state building code with the 2024 International Building Code among the adopted model codes. New Hampshire RSA 155-A also addresses permit and enforcement procedures and reserves permit issuance and fee collection to authorized local jurisdictions, with state enforcement mechanisms in certain situations.
For a homeowner, the practical point is simple: do not assume every patio, driveway, garage slab, foundation or structural concrete project follows the same permit process. Check the city or town where the work will occur. A local building official can tell you whether a permit is required, what drawings or inspections are needed and which code provisions apply to the project.
Driveways often cost more than the simplest slab because they carry vehicles and may require a thicker section, reinforcement, more substantial base preparation, grading and removal of an existing driveway. A broad 2026 national planning range of roughly $8–$20 per square foot is useful for screening a budget, but the final New Hampshire price depends on the written scope.
A 600-square-foot driveway at that broad range suggests approximately $4,800–$12,000 installed before unusually difficult site conditions or premium decorative options. Compare whether each quote includes demolition, haul-off, aggregate base, reinforcement, thickened edges, control joints, sealing and restoration.
Plain patios are often less expensive than driveways because they do not carry vehicle loads, but access and finish can still make a major difference. Current cost guides commonly place plain concrete patios around $4–$12 per square foot, broom-finish patios around $6–$13, exposed aggregate around $7–$18 and stamped concrete higher.
For New Hampshire exterior patios, ask about slope and drainage, subbase preparation, joint layout, curing and sealer. A patio beside a finished house with limited equipment access may require more hand labor than a similar-size slab on an open new-construction site.
Stamped concrete can include integral color, color hardener, release powder, patterned mats, borders, saw cuts, staining and sealer. Current national guides commonly place basic to mid-level stamped concrete in a broad range around $9–$22 or more per square foot, with elaborate multi-color work potentially above that level.
When comparing decorative bids, ask for the exact pattern, color system, border treatment and sealer. Two proposals both labeled “stamped concrete” may represent very different finish packages and labor requirements.
Foundation and garage work should not be priced only from a generic slab square-foot range. Footings, walls, frost-related details, reinforcement, waterproofing, drainage, excavation and structural requirements can dominate the cost. A detached garage slab may also have thickened edges, turned-down sections or other details that change concrete volume.
Use the slab calculator only for the flat slab portion when appropriate. If the project includes footings, frost walls, foundation walls, sonotubes, piers or other structural elements, calculate each component separately or use the structural drawings and contractor takeoff.
Cold-weather placement can require extra planning. The concrete supplier or contractor may use heated materials, accelerating admixtures, blankets, temporary heat or other methods depending on temperature and project requirements. These measures can increase cost, but they may be necessary to protect quality and achieve required performance.
If your project can be scheduled during favorable weather, ask whether that changes price or availability. If winter work is unavoidable, request a written explanation of cold-weather procedures and which winter-related charges are included.
A total price by itself does not tell you whether two quotes are equivalent. Normalize the cost with the quote-comparison calculator, then review scope. A bid that is $1,000 cheaper may omit demolition, reinforcement or base work that another contractor included.
Accurate dimensions and a clear scope are the best starting points. Measure carefully, decide on thickness and finish before requesting quotes, and make sure contractors are pricing the same preparation and reinforcement. For ready-mix, confirm the order quantity and ask about minimums before scheduling the truck.
Good jobsite preparation also reduces avoidable cost. Forms, access and reinforcement should be ready before delivery. If a truck is delayed while a crew corrects forms or clears an access route, waiting-time charges and labor inefficiency can erase any small savings in the concrete price.
Finally, avoid comparing only the lowest total. A complete, well-defined bid often produces a more predictable final cost than a low initial number with many exclusions.

This page is a planning tool, not a supplier quote or contractor bid. Ready-mix prices, delivery charges and contractor rates can change quickly. The calculator intentionally allows you to overwrite price inputs. Broad installed ranges are based on current national cost guidance, while New Hampshire-specific supplier and code information comes from current regional or official sources.
