Flagstone brings natural color and texture to patios, walkways, and pool decks, and most homeowners spend about $15 to $22 per square foot—or roughly $200 to $550 per ton—for material and installation. Your final price depends on where you live, how much stone you need, and how often the space needs upkeep, so build a detailed budget and plan to work with a pro for long-lasting results.
Flagstone Cost Factors
A few key variables drive the overall price of flagstone. Keep these in mind as you map out your project:
Material type: Different types of flagstone can mean the difference between $200 and $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.
Project Type
Installing flagstone in your outdoor space not only adds natural beauty but also increases the functionality and value of your property. On average, flagstone installation costs $15 to $22 per square foot, including materials. Here are the average costs for common flagstone projects.
| Project Type | Average Cost Range |
|---|---|
| Walkway | $4,500–$11,000 |
| Path | $1,900–$5,500 |
| Pool deck | $9,000–$19,800 |
| Driveway | $4,500–$13,200 |
| Patio | $750–$8,400 |
Walkway or Path
A flagstone walkway or path typically costs $1,900 to $11,000 and provides a durable route through your yard that blends with the surrounding landscape. Expect higher prices if crews must remove an existing walkway or level uneven ground before installation.
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
A flagstone pool deck runs $9,000 to $19,800 for 600 to 900 square feet and offers natural slip resistance and cooler surface temperatures around the pool. Budget extra for sealing if you use a saltwater system or hot tub.
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.
Paver Driveway
Installing a flagstone paver driveway costs $4,500 to $13,200 for 300 to 600 square feet. Removing an existing surface typically adds $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
A flagstone patio costs $750 to $8,400 for a typical 50- to 400-square-foot space.
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.
If you're ready to elevate your outdoor space with the timeless appeal of flagstone, connecting with a local professional can make your vision a reality.
Cost by Quantity
The national average cost of flagstone is $15 to $22 per square foot. This price includes the base material, mortar, and labor. Flagstone costs $2 to $6 per square foot for the stone itself. However, some flagstone types cost between $10 and $15 per square foot.
Per Ton
A ton of flagstone costs between $200 and $550. 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 costs an average of $200 per ton. Your average flagstone material costs $350 per ton, while high-end, scarce flagstone materials may cost up to $550 per ton.
Per Pallet
Flagstone pallet prices range from $600 to $2,200, or $0.20 to $0.55 per pound. Pallets weigh three to four tons. One covers 210 to 560 square feet, depending on the dimensions of the stone.
Flagstone Cost by Type
Discovering the right type of flagstone for your project opens up a world of natural colors, textures, and regional variations. With prices ranging from $200 to $550 per ton, you have the flexibility to choose from a diverse selection that complements your design aesthetic. Exploring different types allows you to find a stone that's not only beautiful but also suited to your local climate and landscape.
| Type | Average Cost Range |

| Travertine | $800+ |
| Basalt | $500–$700+ |
Arizona Flagstone
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
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 where saltwater may affect it.
Quartzite Flagstone
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, gray, and green. Its hardiness makes it suitable for high-traffic areas.
Sandstone Flagstone
Sandstone flagstone prices are $200 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.
DIY vs. Hiring a Flagstone Installation Pro
If you’re tempted to handle the work yourself, remember that each stone weighs 12 to 20 pounds per square foot and demands precise cuts and a solid base. A professional installer has the tools and experience to lay the stone correctly, giving you a surface that lasts. Connect with a local flagstone specialist to get your project moving.

Flagstone is a naturally split, sedimentary stone sold in flat, irregular slabs. Homeowners often use it for walkways, patios, pool decks, and even driveways because the coarse surface adds traction and withstands weather swings. Common varieties include sandstone, slate, and quartzite, each offering its own color palette. You can leave the pieces irregular for a rustic look or cut them into uniform shapes for a cleaner design, giving flagstone plenty of flexibility without sacrificing durability.
Regular upkeep is simple. Sweep away leaves and grit each week, pull any weeds that sprout between stones, and hose down the surface when dust builds up. For oily spills, apply an oil-absorbing product immediately to avoid stains. Re-seal the patio every three to four years with a breathable, matte sealant to guard against weather damage and keep traction high.
Flagstone usually costs more than concrete or brick pavers because it’s a quarried, natural stone that requires extra handling and transport. The higher price buys you distinctive color variations, a non-slip texture, and exceptional longevity—advantages many homeowners find worth the extra expense for high-visibility areas like patios, pool decks, and front walkways.
Sealing is the simplest way to protect flagstone from stains, freeze–thaw cycles, and daily wear. Choose a breathable, matte product that preserves the stone’s texture and keeps the surface from becoming slippery. Plan to clean the patio thoroughly, let it dry, and re-seal every three to four years—or more often around saltwater pools—to keep the color consistent and extend the stone’s life.
