How Much Does Flagstone Cost? [2025 Data]

Flagstone is naturally beautiful, with colors ranging from sand or gray to red or purple. It has a rustic charm, mainly if rough cut, and is incredibly durable. It's more affordable than many other types of stone, ranging from $2 to $6 per square foot for the stone itself. However, some flagstone types cost between $10 and $15 per square foot. You'll also need to account for $13 to $16 per square foot for labor.

Flagstone Cost Factors

A few factors influence the cost of flagstone, including the unit of measurement and type of flagstone.

Flagstone Cost by Unit of Measurement

Flagstone pricing is usually given in one of three measurements:

• Per ton

• Per pallet

• Per square foot

When talking to your local paving installers, clarify the size or unit of measurement so you know precisely how much paving you're getting for your money.

Flagstone Cost per Ton

Flagstone costs between $200 and $550 per ton, just for the stone. For a mid-range type of flagstone, expect to pay around $350 per ton. 

A ton of flagstone covers up to 140 square feet, but coverage depends on your flagstone’s type, fit (the space between stones), and thickness. A ton of thicker, denser flagstone could cover as little as 70 square feet. This is a critical pricing factor, so discuss coverage with your contractor.

Flagstone Cost per Pallet

Expect to pay anywhere from $600 to $2,200 for a whole pallet of flagstone. Pallet weights vary but usually fall between three and four tons, which equates to a cost of $0.20 to $0.55 per pound. An average pallet covers between 210 and 560 square feet, but, just as with flagstone coverage priced by the ton, how much square footage you get depends on thickness and density.

Flagstone Cost per Square Foot

Flagstone costs per square foot range from $2 to $6 per square foot for the stone itself and between $15 and $22 per square foot with labor. Expect the price to fall at the higher end of this range for thicker stone and rarer flagstone colors.

Flagstone Cost by Type

Flagstone prices range from $200 to $550 per ton without labor. Prices depend on the type of stone, its quality, and rarity. Colorado red flagstone has the lowest cost, while travertine costs the most. Here’s how each flagstone type compares:

Flagstone Installation Costs 

Many variables impact the cost of flagstone, from the thickness of the stone to its rarity. Delivery, complexity, and accessibility also affect the price of any flagstone installation project.

Project Type

Remember, flagstone costs $15 to $22 per square foot, meaning the cost of your flagstones will depend on the type of project. Here are the average costs to complete flagstone installations:

Weight of Flagstone

The flagstone's weight directly impacts cost, particularly if priced by the ton. Remember, flagstone comes in different thicknesses, with some pavers or flagstone rocks being 2 inches thick or more. Plus, different types of sandstone have different densities, so you get less square footage per ton for heavier stones.

Type of Flagstone

The type of flagstone you choose influences how much you'll pay for the stone itself, and some types, such as those that need sealing, require extra labor. Standard flagstone, such as sandstone, is comparatively inexpensive, costing as little as $200 per ton, whereas scarcer types like bluestone or quartzite with unique patterns and colors can cost up to $550 per ton.

Delivery Distance

Flagstone is heavy, so the more you pay, the further it travels. Stone quarried locally doesn't have far to travel, so you'll get a better price (and have fewer problems with the stone's reaction to your climate). But if you simply must have the rare pink-purple quartzite flecked with gold that has to travel from the other side of the country, you'll quickly rack up extra fees in transport costs.

Site Accessibility

Your contractor will assess how accessible the job site is and figure that into their quote. Labor costs will increase if the contractors manually move the stone a long distance because they can't get the right vehicle or equipment into your yard to do the lifting.

Breakage

Since flagstone is a natural stone, you will want to compensate for variability. For example, contractors often order 25% more stone than they anticipate needing for a project because the stone can vary so much in color, texture, and shape, even when it comes from the same quarry. 

DIY Flagstone Installation vs. Hiring a Pro

If you’re an avid DIYer and want to cut labor costs by doing the installation yourself, you’ll spend between $200 and $550 per ton on materials alone. This means you’ll save somewhere around $13 to $16 per square foot. However, the price of physical labor can quickly outweigh the cost of sheer materials.

The high labor cost compared to the price of the flagstone is because the stone is heavy. So heavy, in fact, you might be better off saving this work for a local paver installation company. Each stone weighs 12 to 20 pounds per square foot, making the installation time-consuming and labor-intensive. Work with a pro to safely and correctly install your flagstone pavers so that they have the longest lifespan possible.

Cost of Common Flagstone Add-Ons

If you want to amplify your outdoor space, be sure to leave space for these popular flagstone add-ons while you budget:

• Fire pit: $200–$3,000

• Outdoor kitchen: $6,300–$26,900

• Outdoor sound system: $250–$1,300

• Patio roof: $14,000–$31,000

• Railing/fencing: $10–$90 per linear foot

• Solar shades: $200–$1,300

7 Ways You Can Save Money While Installing Flagstones 

Flagstone is a heavy material that can quickly add up in material, shipping, and labor costs. Fortunately, there are several things you can do to lower the cost of flagstones for your project, including: 

• Choose a budget-friendly flagstone type, like Colorado red flagstone or Arizona flagstone, over more costly options, like slate, travertine, or basalt.

• Reduce the total square footage to lower material and labor costs. 

• Select a thinner thickness level.

• Choose a material with less density so that the cost by weight is lower.

• Go for flagstone sourced locally to reduce shipping costs.

• Make your site accessible for the delivery and installation.

• Avoid any unnecessary add-ons and stick with the essentials.
