The prices below reflect flagstone pricing versus other paver options.
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:
| Type | Cost per Ton | Description |
|---|---|---|
| Colorado Red Flagstone | $200–$400 | Popular choice for climates with extreme heat or cold |
| Arizona Flagstone | $200–$450 | Readily available, local to the Southwestern US |
| Sandstone | $200–$350 | Easy to find, more affordable than many other types |
| Bluestone | $375–$450 | Resistant to freezing temperatures, requires sealing in coastal locations |
| Quartzite | $400–$450 | Durable mix of sandstone and quartz well-suited to high-traffic areas |
| Limestone | $250–$400 | Commonly found, often left in its natural stone shape rather than squared off |
| Slate | $475–$700 | One of the priciest types, has a rich and textured appearance |
| Travertine | $800+ | Unique porous texture, rustic, and less common |
| Basalt | $500–700+ | Dark volcanic rock, highly resistant to stains and wear |
| Flagstone Rock | $400–$500 | Excellent choice for outdoor steps and natural walls |
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:
| Flagstone Project Type | Total Square Footage | Average Cost |
|---|---|---|
| Walkway | 300–500 sq. ft. | $4,500–$11,000 |
| Pathway | 125–250 sq. ft. | $1,900–$5,500 |
| Pool Deck | 600–900 sq. ft. | $9,000–$19,800 |
| Driveway | 300–600 sq. ft. | $4,500–$13,200 |
| Patio Installation | 50–400 sq. ft. | $750–$8,400 |
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.

Frequently Asked Questions
You can’t go wrong with locally sourced flagstone. If you're working with a landscaper near you, they'll likely be able to source local stone for you and offer insight into how your stone will age over time.
Yes, flagstone is more expensive than pavers, but natural stone lasts longer and has a unique aesthetic appeal that pavers can't match. It is important to make the distinction that flagstone can be different from flagstone pavers. Some pavers are flagstone pavers, and some are not. Flagstone can be uniformly cut and set like pavers or retain the stone’s original shape.
Sealing is essential to keep your flagstone looking new for as long as possible. If you don’t seal flagstone, the surface can wear and stain. It also helps protect the stone’s natural texture. Just make sure you choose a matte sealant to avoid making your stone slippery like a glossy sealant can.
