Flagstone Patio Prices

Flagstone is a popular choice for outdoor landscaping. Creating a flagstone patio adds to the living space of a home and improves the look of the yard. Working with flagstone is a job that is best undertaken by professionals, but aspiring DIY builders can design and lay patio areas as well. Knowing the costs, benefits and potential layout ideas before beginning a project helps ensure a beautiful finished patio.

Cost of Installing a Flagstone Patio

  • Average Cost of Materials: $400-$600
  • Cost of Labor: as much as $2000
  • Cost per Square Foot: $10-$30

Cost will vary depending on the size of the patio, complexity of design, location of the home and whether or not the patio is installed by professionals.

Designing a Flagstone Patio

Homeowners can work on their own or with a professional to design a plan for their outdoor patio area. The organic nature of flagstone lends itself well to nontraditional, flowing designs and interesting visual patterns. Classic square and rectangle shapes can be used as well, but flagstone will differ in appearance from concrete or brick patios due to the various shapes of the stones.

Once the layout has been designed, it's easier to determine the final budget necessary to complete the project. Square footage can be calculated, and a general plan can be made for how long the job will take. Any materials needed in addition to the flagstones such as mortar or decorative plants can be considered as part of the total price. 

The spaces between flagstones may be filled with:

  • Mortar
  • Herb plants
  • Moss
  • Other decorative greenery

Mortar creates a smooth, modern look while plants result in a more whimsical, garden-like appearance. Crushed stone or pebbles are sometimes used to fill in spaces between stones as well. The material chosen depends on the individual tastes of the homeowner and how much maintenance each requires.

Those looking to lay their own flagstone patios will need to do some preparation before getting started. Measuring and outlining the finished area is essential to ensuring an attractive finished project. Irrigation may also be a concern if groundcover is going to be planted in or around the flagstone area. Finally, a secure base must be in place before any flagstones can be laid. Homeowners who are uncomfortable with handling these steps themselves should look into professional services to install the patio.

Benefits of Flagstone

Choosing flagstone for a patio offers many benefits to homeowners. These positive aspects make investing in flagstone a smart choice when looking to create a long-lasting outdoor area.


As the name suggests, flagstones are made of natural stone. They are rugged, sturdy and reliable, making them an ideal choice for any area that sees a lot of use. Flagstone patios can also be sealed against the elements and to protect the surface from heavy foot traffic. Sealing helps to ensure that the stones retain their integrity and beauty over time. When properly maintained, flagstones shouldn't chip, crack or fade even in changing weather conditions.

Expands Living Space

Many people use their flagstone patio areas as outdoor "rooms," taking advantage of the space to enjoy warm summer weather and the sunny afternoons of spring and fall. A patio is also an ideal place for outdoor entertaining. With a good set of furniture and a grill or fire pit, this open-air space becomes an area where friends, family and neighbors can get together and share good food and good company.

Adds Value to the Home

This expanded living space adds to home value as well. By creating a usable outdoor area with an attractive appearance, flagstone patios make properties more desirable. Prospective buyers will appreciate the extra space and the care that went into designing it.

Unique Appearance

Every flagstone has its own individual appearance. In addition to variations in color, flagstones also come in different sizes and shapes. This means that two homes could use the exact same patio layout and yet still wind up with two completely different designs. Homeowners can take advantage of this individuality to create a patio that is unique to their property.

Materials for Flexible Design

Stone comes in many beautiful natural colors ranging from simple neutral gray to brown, red and even shades of blue. This allows homeowners to choose flagstones that reflect the designs of their homes and create a cohesive look between indoors and out. The stones can be laid in any pattern and used to surround a variety of other landscaping details.

Designers may choose to add other featurs such as:

  • Fountains
  • Fire pits
  • Raised garden beds
  • Ponds
  • Pools
  • Walkways and paths
  • Low walls

These decorative elements may be made of other materials such as brick or stone blocks and can easily be incorporated into flagstone patio areas.

Flagstone Patio Maintenance

Before laying a flagstone patio, homeowners should consider installing a mesh weed screen to guard against excessive weed growth. If weeds do grow up between the stones later on, they can be pulled by hand or controlled using natural weed killer.

Other cleaning methods include:

  • Regular sweeping to keep dirt, leaves and other outdoor debris from collecting in cracks or corners of the patio.
  • Washing with a pressure washer or garden hose if something potentially damaging gets on the stones.
  • For tough stains, a mixture of one part bleach to three parts water may be mixed and applied with a tank sprayer. The mixture should be rinsed off a few minutes after application.

Routine use of chemical cleaners can strip the color from the stones. It's best to stick with regular, simple cleaning to avoid stains or ingrained dirt. 

A flagstone patio is a worthwhile investment for any homeowner looking to add space and boost home value. The unique and versatile nature of flagstones makes the material a good choice for many different styles of landscaping. From simple seating areas to expansive gardens that incorporate accents such as fountains and fire pits, flagstones can create a multitude of beautiful looks that can be enjoyed for a lifetime.
