Flagstone Patio Cost Per Square Foot
Installing a flagstone patio typically costs $15 to $21 per square foot for labor and materials. The price can climb to $30 per square foot in high cost of living areas, when using quartzite materials and for wet laid installs.
Dry-Laid Flagstone Patio Cost
Dry laid flagstone is the most affordable option at $1,900 to $4,400 on average. The install starts with excavating and leveling the area before laying down sand and gravel as a base. Once that’s done, installers cut and fit the stone blocks to create your ideal patio shape. Then, they put grout between the stones to secure them in place and create a beautiful finish.
Wet-Laid Flagstone Patio Prices
Wet laid flagstone patio prices are much higher at an average of $2,700 to $7,000. The wet install starts with excavation and leveling of the patio area. Then, they cut the flagstones to size and do a test fit. After that, the installer mixes and pours four inches of concrete to create the base. They must work fast to evenly place the stones in the concrete before it sets up. Grout goes in between the flagstones at the end to complete your desired look.

A flagstone patio offers many benefits over materials like concrete, wood and pavers, like:

To find the best one for your patio, you have to look beyond their appearance to the pros and cons.
