We do not publish an Anchorage price list. What we can give you honestly is the national range for each kind of job, and an explanation of what pushes an Alaska price around: how much frost-prone soil has to be dug out, how much gravel goes back in, how far the truck travels and how late in the season it is.
The price ranges on this page are national figures published by HomeGuide for 2026. They are not our quotes. Alaska labor and material costs, a short building season, access and the ground under your slab all move the real number. Last checked October 2026.
How much does a concrete driveway cost?
By national figures, a concrete driveway runs $6 to $15 per square foot, which is $2,400 to $8,600 for a two-car driveway. Plain concrete is $6 to $10 per square foot and basic decorative work is $10 to $15. In Anchorage the excavation and gravel base are a bigger share of the job than in warm states, because the base is what stops frost heave.
| Driveway | National installed cost |
|---|---|
| Plain, per sq ft | $6 to $10 |
| Basic decorative, per sq ft | $10 to $15 |
| 20x20 (400 sq ft) | $2,400 to $6,000 |
| 24x24 (576 sq ft) | $3,500 to $8,600 |
How much does concrete cost per square foot?
The national figure for an installed slab is $6 to $12 per square foot. A 4-inch slab is $6 to $8 and a 6-inch slab is $8 to $10. That covers forms, base, concrete, finishing and labor on a simple site. Digging out peat or silt, hauling in extra gravel, insulation and a pump truck are added when the site calls for them.
How much does a concrete patio cost? Is my quote for a 20x20 patio fair?
A plain patio is $4 to $12 per square foot nationally, and a stained or stamped one is $8 to $30. For a 20x20 patio the published range is $1,600 to $4,800 plain and $3,200 to $12,000 stained or stamped. A plain 12x12 is $600 to $1,700. For a 12x20 or 16x20, multiply the square feet by the per-foot range. A quote inside the range that also lists the base depth and the mix is a reasonable one.
How much does it cost to pour a slab for a 24x24 garage or a 30x40 shop?
Published national slab prices are $600 to $1,200 for a 10x10, $860 to $1,700 for a 12x12, $2,400 to $4,800 for a 20x20 and $5,400 to $10,800 for a 30x30. There is no published row for 24x24 or 30x40. Simple arithmetic from the $6 to $12 per square foot figure gives $3,460 to $6,900 for 576 square feet and $7,200 to $14,400 for 1,200 square feet. Those numbers are for the flat slab only. Frost footings, insulation, radiant tubing and a thickened edge for a building are priced from the plans.
How much is concrete per yard?
Ready-mix is $119 to $147 per cubic yard nationally, with delivery up to 20 miles. That is the material alone, and it is a national number. Cement is shipped to Alaska, so ask the supplier for the current local rate. On most jobs the concrete is the smaller part of the bill. Excavation, gravel, forms, steel and finishing make up the rest.
How much does it cost to remove and replace an old driveway?
Take the removal figure and add the new driveway figure. Removal is $3 to $8 per square foot nationally with disposal, or $1,200 to $4,500 for a whole driveway. The new pour is then $6 to $15 per square foot. Here, replacement often includes digging deeper than the old slab to get the frost-prone soil out, and that shows as a separate line.
How much does it cost to have old concrete broken up and hauled away?
The national range for removal with disposal is $3 to $8 per square foot. Thick slabs, slabs with heavy steel, and yards where a machine cannot reach cost more. Having the old slab hauled away is part of our written quote whenever a job needs it.
How much more does stamped concrete cost than plain? What about color or stain?
Stamped concrete cost is $8 to $19 per square foot nationally, against $4 to $12 for a plain patio. Published examples are $3,200 to $7,600 for a 20x20 stamped patio, $6,900 to $10,400 for a two-car stamped driveway and $800 to $1,700 for a 4x20 stamped walkway. No separate figure is published for color or stain alone, so we give none. That is priced once you have picked a look and we have seen the slab.
How much does a concrete walkway cost?
The national walkway cost is $7 to $17 per square foot installed. For a walk four feet wide that is $28 to $68 per linear foot, with a typical job at $1,400 to $3,400.
How much does a concrete retaining wall cost?
The national retaining wall cost averages $3,000 to $10,000, or $45 to $270 per linear foot, or $15 to $45 per square foot of wall face. Anchorage walls tend toward the upper part of any range for a plain reason: the footing has to deal with frost, the backfill has to be drain gravel, and taller walls are engineered for earthquake loads.
What does a parking pad or sidewalk cost for a small business?
There is no published figure for commercial parking pads, so we give no number. A small business job is priced after a visit, because truck weights, snow storage, drainage, the accessible route and any work in the street right of way all change the design. For a plain sidewalk the walkway range above is a starting point.
I got three quotes for the same patio and they are far apart. Which one do I trust?
Trust the one that tells you what is under the concrete. When three quotes are far apart in Anchorage, the difference is nearly always the dig and the base. One bidder plans to remove a foot or more of silt and bring in gravel. Another plans to pour on what is there. Ask each for the excavation depth, the gravel thickness, the slab thickness, whether the mix is air-entrained and what steel goes in. The low quote often leaves out the part that prevents heaving.
After tear-out the contractor wants extra for a gravel base. Is that fair?
It can be, if the quote allowed for it. Nobody sees the soil until the old slab is out, and finding peat or wet silt under a 1970s driveway is common here. A good quote states the base depth it assumes and a unit price if more is needed. If you are asked to pay extra for gravel with nothing in writing, look at the excavation yourself, ask how many inches and how many yards, and get the change on paper first.
How do I know if a concrete quote is fair?
A concrete quote is fair when it falls in a sensible range and you can see what you are buying. It should give the area, the thickness, the excavation and gravel depth, the mix strength and air entrainment, the reinforcement, the joint plan, the finish, tear-out and haul-away, any permit and the payment schedule. A one-line number cannot be judged at all.
