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.

  • Rental equipment: $60-$80 per day

DIY vs. Hire a Flagstone Patio Pro

DIY cuts out a lot of the costs of building a flagstone patio but that's only if everything goes as expected. Unfortunately, it's quite hard to get the area level and flagstone cut and set just right. Hiring an experienced patio builder near you is the best way to get the perfect look and the biggest return on your investment.

Why should I build a flagstone patio?

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

  • Durability: Natural stone is sturdy, resists weathering and won’t crack and chip over time.

  • Unique look: No two flagstones are the same, so you’ll never find one that matches your own.

  • Increased value: Flagstone patios increase the value of your home and boost curb appeal.

  • Added space: It’s ideal for chilling, grilling and entertaining without the cost of an addition.

What types of flagstone are used for patios?

Flagstone is basically just flat stone used for hardscaping.

There are many types in this category, such as:

  • Bluestone: Flat, fine-grain sandstone in blue-gray to purple hues

  • Quartzite: Smooth, glossy stone that comes in green, silver, blue and gray

  • Sandstone: Contemporary, earthy stone usually boasting deep red hues

  • Slate: Soft silver, gray or green stone with a weathered look

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