How Much Do Flagstones Cost?

Flagstone Cost Factors

Knowing the biggest cost factors can help you budget your flagstone project. You’ll want to factor in the following as you plan.

• Material type: Different types of flagstone can mean the difference between $200 to $550 per ton.

• Shape: Uniquely shaped flagstone will cost more than thinner, more abundant shapes.

• Shipping: Flagstone is heavy, and shipping it from a long distance will add to the price. Choose a local supplier to save on shipping costs.

Flagstone Installation Cost

Flagstone installation costs $15 to $22 per square foot, including materials. Since the average stone weighs 12 to 20 pounds per square foot, it’s a labor-intensive job.

Flagstone Walkway or Path

A flagstone walkway or path costs between $1,900 to $11,000 on average. You’ll pay more if you need to demolish an existing walkway or level an uneven surface.

A flagstone path gives a natural look without compromising walkability. A hard, more compact material is preferable for this purpose as it will hold up to foot traffic. If you choose stepping stones surrounded by crushed rock or gravel, you may pay less for the preparation and installation.

Pool Deck 

The price of a flagstone pool deck ranges from $9,000 to $19,800, assuming it’s 600 by 900 square feet in size. If you have a saltwater pool or hot tub, prepare to spend more on sealing.

Flagstone is a great choice for a pool deck. Certain types are naturally heat-resistant or slip-resistant, which helps to protect your family from burns or falls.

Pavers Driveway

A flagstone pavers driveway costs $4,500 to $13,200 for 300 by 600 square feet. Removal of the existing surface runs an additional $300 to $1,200.

Most flagstone driveways are custom-made. They call for a thicker cut, and installing them is both labor- and preparation-intensive. Many homeowners include curves, curbs and other features, which can increase the total by $1,000 to $3,000. You can hire a paver installer near you to handle this job.

Patios

The cost to install a flagstone patio is $750 to $8,400. This range assumes a typical 50-by-400-square-foot patio.

Flagstone patios are popular, and they can even help lower utility bills to a degree. Heat-absorbent Arizona flagstone doesn’t reflect the hot sun back toward your house, which takes some pressure off your air conditioner.

Flagstone Cost Per Square Foot

The national average cost of flagstone is $15 to $22 per square foot. This price includes the base material, mortar and labor. The average cost for the stone alone runs along $2 to $6 per square foot.

Flagstone Price Per Ton

A ton of flagstone costs between $200 and $500. One ton can cover 70 to 140 square feet, depending on the type of stone and the thickness of the stone.

A lower-priced flagstone, such as Oklahoma Brown, costs around $200 per ton. Your average flagstone material costs around $375 per ton, while high-end, scarce flagstone materials may cost up to $550 per ton. 

Flagstone Pallet Prices

Flagstone pallet prices range from $600 to $2,200, or $0.20 to $0.55 per pound. Pallets weigh around three to four tons. One covers 210 to 560 square feet, depending on the dimensions of the stone.

Flagstone Pricing By Type

Flagstone pricing ranges from $200 to $550 per ton. You can find dozens of varieties unique to each region, with a few common types available in most areas.

Arizona Flagstone Prices

Arizona flagstone prices are $200 to $450 per ton. Since it is one of the most common varieties, the price depends on location and color variations. As the name suggests, this flagstone is found in the Southwestern United States. It resists heat absorption, which makes it popular for poolside patios.

Bluestone Flagstone Prices

Bluestone flagstone costs $375 to $450 per ton. The non-slip surface and unusual color are perfect for pool decks. Bluestone comes primarily from New York and Pennsylvania. It is particularly suited to freezing climates, but it needs sealing in areas in which saltwater may affect it.

Quartzite Flagstone Prices

Quartzite flagstone prices range from $400 to $450 per ton. This natural material combines sandstone and quartz for a hard, long-lasting surface. Commonly found in Idaho, Oklahoma and Northern Utah, quartzite comes in a wide range of colors such as silver, gold, light tan, blue, grey and green. Its hardiness makes it suitable for high-traffic areas.

Sandstone Flagstone Prices

Sandstone flagstone prices are $250 to $350 per ton. Like Arizona flagstone, this variety costs less because it is easier to find. Sandstone is ideal for hot, dry climates with mild winters because it stays cooler. Colors range from pale cream to dark red.

Colorado Red Flagstone Prices

Colorado Red flagstone costs $200 to $400 per ton. The price depends on the size and color. This stone’s colors run from pink to reddish-purple. It’s a favorite for harsh climates with a blazing hot summer sun or icy winter wind.

Natural Flagstone Prices

Natural flagstone prices are $200 to $550 per ton. You can get hundreds of different colors and variations depending on your location. Flagstone costs more than concrete pavers, but it may be a better investment. If you choose a type harvested from a similar climate, you’ll have fewer problems with damage from cold or humidity.

Flagstone Rock Prices

Flagstone rock costs $400 to $500 per ton or $0.40 to $0.50 per pound. Although it mostly comes in sheets that are one to two inches thick, you can often find bigger sizes. Flagstone rock makes a great choice for garden steps and retaining walls. You can get sizes as large as 24 by 36 inches, and rocks up to several inches thick.

Crab Orchard Stone Prices

Crab Orchard stone prices are $350 to $450 per ton. If you live in the western half of the U.S., you can expect to pay the most. Native to Tennessee, Crab Orchard stone is best known for its striking color range from gray to orange-brown. It makes a great patio or walkway but will crack under a car.

Flagstone vs. Fieldstone Costs

Fieldstone costs $150 to $250 per ton, compared to $200 to $500 per ton for flagstone. It’s less expensive because it is harvested from the ground instead of a quarry.

Fieldstone is ideal for a fireplace, retaining wall or anywhere you don’t need a smooth, flat surface. For walkways or patios, you’ll probably want to use flagstone.
