Factors in Calculating Flagstone Patio Cost

The cost of a flagstone patio is typically calculated based on the size of the patio, the type of flagstone used, and the complexity of the job. The average cost of a flagstone patio across the United States is $3,600, though this can differ from local averages due to factors such as labor costs and availability of flagstone materials. Homeowners will want to consider the following factors when estimating the cost of a flagstone patio.

Patio Size

The cost of installing a flagstone patio varies from $15 to $30 per square foot, depending on the season and location. Generally, the larger the space, the more expensive a flagstone patio cost will be. This is because larger patios require more flagstone, mortar, and installation labor hours. Additionally, larger patios may require more specialized tools and equipment to complete the job, which can add to the overall cost of flagstone installation.

But a larger patio may not always cost more than a smaller space. The complexity of the design and the type of stone are also influential factors for homeowners to keep in mind.

Patio SizeSquare FootageInstallation Cost Range
7- by 7-feet49$735 to $1,470
10- by 12-feet120$1,800 to $3,600
16-by-18 feet288$4,320 to $8,640
20- by 20-feet400$6,000 to $12,000

Stone Type

The cost of a patio is heavily influenced by the type of flagstone selected. Flagstone is available in several varieties, each with its own unique appearance and features as well as drawbacks.

Bluestone is a dense and durable material that can withstand tough weather conditions, making it ideally suited for homes in areas with harsh winters or extremely hot temperatures. Quartzite is another great option for outdoor use, since it is resistant to staining and weathering and can remain looking good for many years after installation. Sandstone is a great option for keeping stones cool and is also known for absorbing water, which can cause damage—these features make it an ideal material for patios in dry and hot regions, such as Arizona or New Mexico.

The following table shows pricing per ton for three common stone types. When homeowners are shopping for a pallet of flagstone, or 2 tons’ worth of materials, the prices are double.

Stone TypeCost Range (Per Ton)
Bluestone$375 to $450
Quartzite$400 to $450
Sandstone$250 to $350

Installation Method

There are three main installation methods when it comes to flagstone patios, and each one has its own price range according to complexity.

Dry-laid flagstone patios are constructed by laying the flagstone over a bed of sand and gravel. This type of patio requires little to no mortar and is quick and easy to install. The stones are held together and stabilized by the weight of the stones and the friction of the sand and gravel.

Mortar-set flagstone patios are constructed by laying the stones on a bed of mortar. This type of patio requires more time and effort to construct, as each stone needs to be carefully placed and leveled in the mortar. Although mortar-set patios require more work, they are less likely to shift or sink over time due to the extra support and stability provided by the mortar.

Concrete-set flagstone patios are constructed by pouring a concrete slab and then laying the stones on top. This type of patio provides the most stability, as the stones are locked into the concrete and are highly unlikely to shift or settle over time.

Design Complexity

When homeowners are considering flagstone pricing, it is important to take into account the complexity of the design. Intricate designs may require more materials, tools, and labor, as well as more expensive types of flagstone. Incorporating curves, circles, steps, water features, and fire pits can also significantly increase the cost of the project.

However, there are many benefits for those willing to invest in a more complex design. An intricately designed flagstone patio can add value to a home, create a more aesthetically pleasing outdoor living space, and provide a great area for entertaining guests. On the other hand, a straightforward design will likely be more economical for homeowners looking to minimize costs on their flagstone patio installation.

Labor

The typical flagstone cost per square foot for labor is between $11 and $15. The final price will depend on the complexity of the installation as well as local labor rates. For example, the labor cost of installing a 50-square-foot patio could be between $550 and $750, while a 400-square-foot patio could cost as much as $4,400 and $6,000 for labor alone.

When searching for “flagstone installers near me,” homeowners will want to consider both the cost of labor and the cost of materials. Homeowners are generally advised to obtain quotes from at least three contractors before making a decision, while being aware that some contractors may charge higher rates for labor but offer lower prices for materials.

Geographic Location

The cost to install a flagstone patio is largely influenced by the location of the job. Companies must source stones from where they naturally form. Transportation costs increase with distance from the source of the stone because of the fuel and labor costs associated with long-distance hauling. Depending on the flagstone’s size and weight, the shipping cost can be significant.

For example, if the flagstone is being shipped from a quarry on the other side of the country, the cost of transportation will likely be much higher than if it is being shipped from a quarry that is closer to the installation site. The following table lists some average costs for a 200-square-foot flagstone patio in different locations across the country, including materials and installation.

Geographic LocationAverage Flagstone Patio Cost
Richmond, Virginia$3,000
Bozeman, Montana$3,302
Columbus, Ohio$3,600
Los Angeles$3,930
New York City$5,245

Additional Costs and Considerations

When homeowners are installing a flagstone patio, it’s recommended that they take into account factors like permits, seasonal effects, and any related projects to get an accurate cost estimation. Keeping the following potential considerations in mind can help ensure that the total cost of the project is calculated as accurately as possible.

Flagstone Patio vs. Stamped Concrete

Stamped concrete is a style of poured concrete designed to mimic the look and texture of brick, flagstone, tile, slate, and other common patio materials. It can be dyed and sealed to achieve the desired appearance, often at a much lower expense than for the real thing.

On average, a 200-square-foot flagstone patio costs between $3,000 and $4,200, while a stamped concrete patio of the same size costs between $1,600 and $5,600. Concrete patio costs for stamped concrete are typically determined by the square foot, with a basic single-color design costing around $8 per square foot and a more complex design costing up to $28 per square foot. Ultimately, the decision between flagstone patio pavers versus stamped concrete comes down to the homeowner’s personal preference, since the prices are so close.

Permits

A building permit is a legal document granting permission to begin construction on a residential structure. In many cases, a permit may be required for a patio installation. Permits are necessary to ensure that the patio is constructed to local codes and regulations and to ensure that the patio is safe. When homeowners are applying for a permit, all necessary information must be included. This typically includes details about the patio’s design, size, materials, and location.

If required, a patio construction permit can be obtained for as little as $150. Generally, contractors will pull the necessary permits for a job and roll the costs into the installation cost. Homeowners will want to confirm this before assuming a permit has been pulled and paid for.

Seasonality

Seasonality can significantly impact the cost of installing a flagstone patio. During the summer months when demand is high, contractors may charge more for their services. On the other hand, during the winter months when demand is low, contractors may offer discounts on the cost of labor and materials.

Flagstone patios can be installed any time of year, but the best time to install one is in the late spring or early summer when the ground is warm and the weather is dry. This will help to ensure that the patio is installed in time for homeowners to enjoy it while the weather is pleasant. Conversely, a late-fall patio project may be a money-saving option for the homeowner who isn’t in a hurry or wants to save on installation costs.

Related Projects

A homeowner might consider completing additional projects when having a flagstone patio installed. This can help their dream outdoor space become a reality in less time and for less money. Common related projects might include some of the following:

  • installing outdoor lighting
  • landscaping the space around the patio
  • installing a fire pit
  • installing a pergola
  • adding a water feature such as a fountain
  • building a seating area
  • installing an outdoor kitchen

If a homeowner wishes to add additional projects to their flagstone patio installation, they will need to be aware that doing so will likely result in increased costs. Homeowners will want to take into consideration any associated expenses when planning a patio building project, such as fees related to hiring one of the best landscaping companies to create an enviable backyard space.

Flagstone Patio Cost by Type of Installation Method

There are several different methods for installing a flagstone patio, including dry-laid, mortar-set, and concrete-set. Each of these methods has its own advantages and disadvantages, and the cost of the project can be impacted by the chosen option.

Installation MethodCost (Per Square Feet)Average Cost for 50 to 400 Square Feet
Dry-laid$15 to $17$750 to $6,800
Mortar-set$16 to $18$800 to $7,200
Concrete-set$19 to $21$950 to $8,400

Dry-Laid

The cost of a dry-laid flagstone patio can range from $750 to $6,800, depending on size and labor costs. Flagstone itself typically costs between $4 and $6 per square foot, and labor costs average an additional $11 per square foot. This makes dry-laid flagstone one of the most cost-effective options for a patio, with a price range of $15 to $17 per square foot.

A dry-laid flagstone patio is an affordable outdoor living solution that provides an attractive, natural look. The stones are placed without the use of mortar, creating a rustic, organic feel that is designed to settle with the ground. This type of patio is easy to install and requires only minimal maintenance. However, over time, the stones in a dry-laid patio may move and become a hazard.

Mortar-Set

The cost to install a mortar-set flagstone patio ranges from $800 to $7,200 for a 50- to 400-square-foot space. On average, contractors charge about $12 per square foot for labor, and the stone itself costs between $4 and $6 per square foot. The total cost of the project comes to $16 to $18 per square foot, which is slightly more than the cost of installing dry-laid flagstone.

A mortar-laid patio is much more durable and permanent than a dry-laid patio. Mortar provides a strong bond between the stones, keeping them in place and preventing shifting or cracking. It also helps to prevent weeds from growing in between the stones. In addition, mortar helps keep the patio surface even and level and provides a more professional, finished look.

Concrete-Set

Installing a concrete-set flagstone patio (otherwise known as a wet-laid flagstone patio) comes with a hefty price tag, ranging from $950 to $8,400 for an area of 50 to 400 square feet. Labor costs can go as high as $15 per square foot, while stone materials are approximately $4 to $6 per square foot. Altogether, this is the most costly and labor-intensive flagstone patio installation option at approximately $19 to $21 per square foot.

The pros of a concrete-set flagstone patio are that it is stronger and more durable than a mortar-set or dry-laid patio, lasts longer, and requires less maintenance. However, the process of setting the stones with concrete can be time-consuming and labor-intensive, and concrete-set is not as flexible as mortar-set or dry-laid, making it difficult to make changes or repairs.

Benefits of Flagstone Patios

From durability and low maintenance to aesthetic appeal and versatility, flagstone patios have a lot to offer. Homeowners can learn more about why flagstone patios are a great choice for an outdoor space by reading the benefits listed below.

Durability

Flagstone patios are an ideal choice for outdoor living spaces due to their extreme durability. Not only is flagstone a natural stone that has been used for centuries, but it is also incredibly strong. It can withstand harsh weather conditions, UV rays, and general wear and tear, and it’s resistant to cracking, chipping, and fading. All of this ensures that a flagstone patio will retain its beauty for years to come.

While wood patios can warp, rot, and decay due to moisture, extreme temperatures, and insects, making them much more susceptible to damage, flagstone patios offer long-term durability and dependability.

Availability

Flagstone is an abundant material that can be found in many areas around the world. It’s easily sourced from quarries or riverbeds and is simple to shape, making it ideal for a variety of building and landscaping projects, including outdoor patios.

Thanks to its abundance, homeowners looking to install a flagstone patio on a tight deadline can get started with their project quickly, without having to wait for materials to be sourced and shipped. In addition, the abundance of available materials helps keep flagstone prices competitive, so homeowners can stay within their budget.

Long-Term Affordability

Flagstone may be more expensive up front than other materials for outdoor patios, but its low maintenance requirements and long lifespan make it a more cost-effective option in the long run. Compared to wood and concrete, flagstone requires less upkeep, which can save homeowners money over time. Additionally, its durability means fewer repairs or replacements, providing further savings in the long term.

Many homeowners choose flagstone for its affordability. Compared to brick, for example, flagstone is the more economical choice for homeowners focused solely on cost. Flagstone can also increase the value of a home more than other types of outdoor living space materials, making it a great investment that absorbs some of its initial costs.

Customization Options

Flagstone bricks and pavers are available in a variety of shapes, sizes, colors, and textures, so it is possible to create a wide range of designs and patterns. Additionally, flagstone patios can be enhanced with additional customizations such as fire pits, water features, and seating areas to further personalize the outdoor space.

Customizations are a benefit of flagstone patios because they allow homeowners to create a unique design that reflects their individual style and preferences. A customized patio can also increase the overall aesthetic appeal of a property, which can be attractive to potential buyers and add significant value to a home.

Ease of Installation and Maintenance

Flagstone patios can be installed quickly and easily without the use of mortar or grout, making the process much simpler than with other patio materials. Maintenance is also straightforward and requires only occasional sweeping or spraying down with a hose. An extra layer of protection can be provided every few years with a sealant, to guard against water damage, staining, and weathering.

Furthermore, flagstone is highly durable and won’t warp or rot, so it requires minimal repairs. Plus, it doesn’t need painting or staining like wood patios. All in all, flagstone patios are a low-maintenance and long-lasting solution for outdoor living.

Flagstone Patio Installation: DIY vs. Hiring a Professional

When it comes to installing a flagstone patio, homeowners can choose to do it themselves or hire a professional. DIY projects are often rewarding, but it’s important for a homeowner to understand the complexity of laying flagstone and consider if it’s something they’re prepared to tackle on their own.

Flagstone patio DIY projects can be a great way to save money, but they can also come with some risks. Flagstone patio installation requires a certain level of skill and knowledge, including knowledge about how to lay the stones properly and how to ensure that the patio is level and secure. If the homeowner lacks sufficient experience, the project can quickly become more difficult than expected, and the risk of costly mistakes increases. It’s typically recommended that homeowners take on a DIY flagstone patio only with the dry-laid-method, as it offers more room for error.

The table below shows what a homeowner can expect to pay in materials and equipment for a 200-square-foot flagstone patio DIY installation.

MaterialAverage Cost 
Flagstone$600 to $1,000
Sand and gravel$95 to $105
Equipment$60 to $80
Sealer$100 to $200

Based on these numbers, a DIY flagstone patio costs between $855 and $1,385, compared to the average professional installation cost of $3,600. A DIY patio can certainly offer savings, but there’s no guarantee the final product will meet a homeowner’s expectations. It’s recommended that homeowners always hire a professional for a concrete-set flagstone patio, as the installation of wet-laid material requires experience, knowledge, and specialized equipment that most homeowners simply don’t have.

Ultimately, the decision to DIY or hire a professional comes down to a homeowner’s knowledge, experience, and comfort level. If a homeowner is confident in their abilities and has the time to dedicate to a flagstone patio installation, DIY is an option. However, if there is uncertainty about the project, hiring a professional is the best way to ensure the job is done right.

How to Save Money on Flagstone Patio Cost

Flagstone patios can be a great addition to any backyard, but they can also come with a hefty price tag. Fortunately, there are several ways to save money on flagstone patio costs without sacrificing quality or aesthetic appeal.

  • Look for deals. Search for “cheap flagstone near me” and shop around to find the best prices on materials.
  • Maximize your budget. If possible, limit the size of the project and adjust the design to make the best use of your budget.
  • Consider some DIY work. Whether tackling an entire DIY patio installation or just removing an existing patio, taking on some of the work yourself can decrease labor costs.
  • Reuse or recycle. Reuse flagstone from another project or buy it from a salvage yard, where quality materials can often be purchased at a fraction of the cost.
  • Ask about discounts. For upscale or larger designs, seek out contractors who offer discounts for larger projects.
  • Search for discounted materials. Ask local stone suppliers and masonry contractors if they have any leftover flagstone from previous jobs that they will sell for a discount.
