How Much Does a Flagstone Patio Cost? [2025 Data]

How Much Does a Flagstone Patio Cost Per Square Foot?

The cost to install a flagstone patio fluctuates between $15 to $30 per square foot, depending on the time of year you buy materials, where you live, and some other factors.

The bigger the patio, the more you’re going to pay. So, if you want an average flagstone patio that is 300 square feet, then you’re looking at paying $4,500 to $9,000.

Flagstone Patio Cost Breakdown

The bulk of the cost to install a flagstone patio comes from the materials, labor, and whether you need a permit.

Cost of Materials

The cost of the flagstone itself takes up a large part of your total, with prices ranging anywhere from $200 to $550 per ton on average. Some materials, like travertine or basalt, can cost upwards of $800 per ton, however. The color and type of flagstone will influence your material costs. There are ten main types of flagstone available, each with benefits and downsides, including:

• Arizona Flagstone: Comes in unique shades ranging from pink to red shade for a warm aesthetic, but best suits southwestern U.S. climates due to its water-absorbing properties and susceptibility to the freeze/thaw cycle

• Basalt: Extremely durable and heat-resistant, but hard to cut due to its durability

• Bluestone: Dense and durable, but the color fades easily

• Colorado Red Flagstone: Earthy red tone handles high heat well, but may be less available nationwide

• Flagstone Rock: Stays cool even in full sun and has good traction, but irregular pieces make it time-consuming and costly to install

• Limestone: Durable and withstands weathering well, but chemicals and other acids damage it

• Quartzite: Holds up against stains and weathering well, but costs more and is harder to install

• Sandstone: Keeps the stones cool but absorbs water, which may damage it 

• Slate: Easiest to mold, but easiest to break apart

• Travertine: Beautiful appearance and naturally slip-resistant, but has a higher cost and has a porous surface that makes it susceptible to stains and damage without proper maintenance

After you’ve picked out the type of flagstone you want, choose the color that goes hand-in-hand with your house or outdoor decor.

Cost of Labor

The cost of labor depends on the contractor you hire but will usually sit between $1,000 and $4,000. Keep in mind that certain contractors may have higher labor costs, but some may offer cheaper prices for materials. Include both of these numbers when picking between contractors, and get a quote from at least three pros before signing a contract.

Cost to Install a Flagstone Patio by Location

One of the biggest factors that will influence the cost to install a flagstone patio is where you live. Companies need to source these stones from where they form naturally, so the further away you are from that location, the more you’re likely to pay. That’s why states such as Florida will have a lower cost for limestone than New York.

Here are the average costs for a 200-square-foot flagstone patio:

Cost of Flagstone Patios By Installation Method

There are three main methods of laying a flagstone patio: Dry-laying the patio, which is the most affordable, wet-laying the patio, and using a mortar-set method, which is similar to wet-laying.

Dry-Laid

Dry-laying a flagstone patio costs around $1,900 to $4,400 on average. This is more affordable because the patio will sit on top of sand and gravel, rather than poured concrete.

First, local patio contractors cut and shape slabs of stone blocks to meet the concept you created. After they’ve been cut, the contractor will put grout between the stones. The grout keeps the stones in place and helps create the elegant finish that defines flagstone patios.

Wet-Laid

A wet-laid flagstone patio can range from $2,700 to $7,000. This extra cost comes from the contractor needing to create a concrete base, rather than a sand and gravel base.

Once the contractors pour the concrete, they need to work fast to place the stones, as the concrete has a time limit before it sets. After the concrete sets, there is little they can do to change the position of the stones. Finally, the contractor will put grout between the stones to give a stylish finish. Consider this the final piece of the puzzle.

Mortar-Set

If you already have a suitable concrete base, then you could pay between $2,000 and $5,000 for a mortar-set flagstone patio. Mortar-set patios are similar to wet-laid patios, but the difference is the contractor won’t need to lay down concrete beforehand. They will either install the mortar and stones over existing concrete or another hard structure.

Cost of Flagstone vs. Stamped Concrete Patios

The difference between flagstone patio cost vs. stamped concrete cost is minimal. A flagstone patio costs between $750 and $8,400, while a stamped concrete patio costs anywhere from $400 to $18,900, depending on the size and complexity of the design.

Because there may be only a few hundred dollars between projects, it comes down to your personal preference. Flagstone patios offer a more rustic look, while stamped concrete tends to look more like cracked marble floors. No matter what style of house you’re going for, there are plenty of different patio types that can help complement the rest of the home.

Other Cost Factors

After accounting for the size, materials, labor, location, and method type, you may encounter other parts of building a flagstone patio that can hike up costs. Here’s a quick rundown of how much these other cost factors could affect your total budget. 

Demolition and Prep

If you have an existing patio, you’ll first need to demolish it. Concrete removal costs range from between $550 and $1,700 on average. You can learn how to remove concrete yourself to save on costs, but you’ll also need to remove the concrete, which adds another $225 per ton to your costs. Since this is a labor-intensive project, it may be better left to a local concrete disposal company to handle it for you. 

Repairs

If your flagstone patio needs repairs down the line, anticipate spending between $3 to $30 per square foot on patio repair costs. Hiring a patio repair pro near you to fix your flagstone patio as soon as you notice a crack, chip, or uneven surface can help prevent larger upfront costs or worsening problems. 

Cleaning and Resealing

Resealing a patio costs between $300 and $550 on average. On average, you’ll want to reseal your patio every 18 to 36 months. Always clean your patio before sealing for a smooth application. Vinegar, soap, and water, along with a gentle scrub brush, are enough to clean your flagstone patio, which will only cost around $10 to $15 and last for several cleanings.  

Accessibility

Installing a wheelchair ramp costs between $1,100 and $3,400, or $2,200 on average. Flagstone patios aren’t the friendliest material for an accessible patio, but adding a ramp and ensuring the flagstone pavers are level and as even as possible can help make your patio more accessible. 

Permits

Certain cities or counties may require you to file for a permit to add a patio to your house. However, since flagstone patios and paver patios aren’t permanent structures—as a concrete patio would be considered—the majority of homeowners having one installed won’t need a permit. Still, you should check with your local building department to see if one is required.

You might need to pay for a permit if you’re installing other things in your outdoor area, like stone steps, which will need a permanent foundation. The cost of stone steps will also drive up your total by an average of $1,400 to $5,500.

How Much Does It Cost to Install a Flagstone Patio Yourself?

The cost to DIY a flagstone patio is between $855 to $1,385 on average for a 200-square-foot patio. Most people who tackle a DIY flagstone patio prefer the dry-laid method because it doesn’t require you to pour and mix concrete. Although you’ll still have to cut stone yourself, you aren’t on the clock when dry-laying a patio, so you can take your time without worrying about concrete setting before you’re done.

Most of this cost is the flagstone itself, which costs around $600 to $1,000 for 200 square feet. You’ll also need sand, grout, and gravel, which cost around $95 to $105. Because you’ll need to place a seal and cut stone, you might need to borrow specific equipment, which will cost around $60 to $80 for the equipment and around $100 to $200 for a gallon of sealer.

If you’re set on a wet-laid flagstone patio, you’ll want to leave that to the professionals. This kind of labor-intensive work with a time limit isn’t conducive to a DIY job unless you have experience laying patios. We recommend contacting a brick paver company near you for a professional installation.
