Flagstone Prices

As you’ll soon see, there are numerous types of flagstone and various cost considerations, making the average flagstone walkway cost pretty volatile. Nonetheless, the average flagstone prices are as follows:

  • The minimum cost of flagstone is $2 per square foot (or $150 per ton)
  • The maximum cost of flagstone is $5 per square foot (or $900 per ton)
  • One ton of flagstone covers between 100sf and 300sf, depending on the thickness

Bear in mind, this is just the cost of flagstone and does not include joint filler, such as gravel, or installation costs (if you hire a contractor).

Flagstone is generally purchased through a landscaping contractor or direct source in order to get the best options and price. Flagstone can be challenging to cut into small pieces, so it’s often sold only in large amounts (tons). One of the main costs of obtaining flagstone is delivery and installation because of its weight (both not included above).

Flagstone Walkway Installation Cost

All remodeling projects include other costs besides materials. After all, what good is that beautiful flagstone if you don’t install it anywhere? Therefore, to get a true flagstone walkway cost, you have to consider labor, delivery and related expenses.

All in, you should expect to pay between $15 and $20 per square foot for a finished walkway project. This includes everything from labor and delivery to materials and fillers.

On the other hand, if you’re installing your flagstone pathway yourself, you just need the flagstone and some type of joint to surround your walkway. For gravel-filled walkways, costs can average around $10 per square foot. Using hand-mortared custom joints can raise your flagstone path cost anywhere between $20 and $30 per square foot.

Flagstone Walkway Cost Factors

Given the $2/sf to $5/sf cost of flagstone, there are certainly a few elements that drastically affect your flagstone price. Keep all cost considerations below in mind to ensure you don’t overspend on your flagstone walkway project.

Type of Flagstone

Just like your counters, certain flagstones cost more than others. While Bluestone costs as little as $150 per ton, other types of flagstone can enlarge up to $900 per ton. These prices are largely determined by the durability.

Location of Flagstone

When considering cost estimates, it’s important to find stone companies nearby. If you live near a distributor or landscape nursery that has flagstone in stock, prices will be considerably lower as opposed to custom-cut stone that needs to be shipped across the country. Just like anything else, traveling longer distances costs more.

Shape of Flagstone

All flagstones were not created equal. In addition to durability, flagstone comes in all sorts of shapes and sizes. Believe it or not, those shapes do have an effect on your flagstone patio walkway cost.

Installation for factory cut edges is less expensive than irregular stones because irregulars require chipping and fitting. Put simply, less work goes into creating factory cut edge flagstone. That lower cost is passed onto you at the stone company.

Pattern of Flagstone

Some homeowners like a mosaic pattern. Others like a very consistent pattern across the entire pathway. Obviously, custom designs bring on longer installation times, which bring on custom prices. To keep your flagstone walkway price down, choose a simple pattern.

Extra Flagstone

To ensure a pristine flagstone design, many landscapers recommend buying extra flagstone. There are two reasons to purchase extra flagstone. First, to install a beautiful mosaic flagstone walkway, you need options in terms of shapes. Installation is more of an art than a science with any irregular-shaped flagstone pathway. As such, you need plenty of options towards the end of the process.

After all, you don’t want to get down to the last quarter of the project and have to order more flagstones because you didn’t purchase enough in the first place!


You can not install a flagstone walkway in the rain or snow. If it starts raining when your walkway contractor is on site, chances are, you’ll have to reschedule their visit. Any changes in schedule will raise your total cost of flagstone.

Types Of Flagstone & Their Prices

There are hundreds of different types of flagstone and each one varies with color and style. Some of the more popular flagstones and their prices are:

Basalt - $330/ton

Common internationally, Basalt is a softer flagstone that offers great insulation. While Basalt can get gloomy after years of use, it does limit sound unlike any other type of flagstone.

Bluestone - $330/ton

Bluestone is typically used in New York and Pennsylvania, which makes perfect sense because it can stand up against freezing temperatures. However, despite a very low price per square foot, Bluestone requires more maintenance and sealing to preserve its appearance.

Sandstone - $550/ton

Used primary in the Southwest, Sandstone, also known as Arizona flagstone, features various color pallets from beige and red to pink and gold. It does not do well in colder climates, but maintains a relatively cool surface in hotter climates.

Quartzite - $575/ton

Not all flagstones are common to designated regions. Quartzite is popular in Idaho, Oklahoma and Northern Utah. While the cost is more, Quartzite can stand up to stains much better than Sandstone. If your walkway sees or will see a lot of foot traffic, Quartzite is a terrific choice.

Slate - $575/ton

Much like Bluestone, Slate is common on the East Coast and needs sealing to reduce stains and other future repairs. Slate has an antique appearance and is relatively soft compared to other flagstones.

Limestone - $595/ton

Even though Limestone is good for humid climates, Limestone flagstone is very common in Indiana. Limestone colors range from gray and beige to black and yellow.

To make your decision easier, durable flagstones contain the following characteristics:

  • Flat texture
  • Scratch and stain resistance
  • Minimal surface pits
  • Weather resistance
  • Similar hues
  • Sound absorbency

Not all flagstone is treated the same. With countless types and styles, it’s important to consider how much wear and tear your walkway paver will get and if it will be exposed to chlorine or salt. Choosing varieties like Limestone or Bluestone are popular options for walkways that will see high traffic throughout the year.

Flagstone Path Designs & Cuts

Flagstone has been used as pavers since the early 1900s. It provides a natural look to any landscape, regardless of location.

While there are several different variations of flagstone, it also comes in different cuts to accommodate certain walkway projects. Some of these cuts have various terms that you should be aware of when speaking to a contractor or professional landscaping company.

  • Ledgestone: Cut strips of flagstone that are flat and made for stacking on steps or retaining walls.
  • Milled: Refers to cut flagstone that generates an edge on one or more sides.
  • Mosaic: A random pattern of flagstone.
  • Pavers: Flagstone cut into squares or rectangles.
  • Sawn Bed Veneer: Flagstone cut to a specific depth, leaving a natural surface on one side.
  • Slab: Large, irregular pieces of stone. This is how most pieces are sold.
  • Treads: Flagstone that is milled and machined to be used in stairs or risers.
  • Tumbled: The process of smoothing the stone and softening the edges.

Advantages Of Flagstone Walkways

Even though concrete is cheaper than flagstone, this unique walkway material brings an abundance of design benefits concrete or gravel simply do not offer.

  • Compliments landscape
  • Enhanced elegance
  • Unique appearance
  • Offers customization

Flagstone offers a natural beauty that highlights the walkway as well as the surrounding landscape. Homeowners who spend thousands on a new flagstone patio, pool area or landscaping do not want to skimp on the walkway or sidewalk leading to and from your home. Flagstone walkways offer elegance and a style that can only be matched by other natural or man-made materials.

One huge advantage is that flagstone creates a one-of-a-kind look that allows homeowners to design a walkway that is custom to your home and landscape. This is a great alternative to concrete or gravel walkways that really don't stand out or create the curb appeal most homeowners are looking for.

Types Of Flagstone & Their Prices

Disadvantages Of Flagstone Walkways

No walkway material is perfect and neither is flagstone. Beyond the cost, there are a few drawbacks all homeowners should know before purchasing any type of flagstone.

  • Very heavy
  • No standard shape
  • Difficult to deliver
  • Limited availability

The biggest disadvantage to working with flagstone is the weight and irregular design, both of which make installation and delivery a little bit difficult. Therefore, prior to purchase, you should visit the distributor or see exact photos of the flagstone. This will help assure that the pieces are a good fit for you and your walkway project.

Flagstone has a 1.5” to 2.5” thickness. While this is good for creating walkways, it can be challenging to level the surface out enough to accompany fluctuating thickness.

Flagstone averages about 85sf to 100sf per ton of material. This can make it challenging to move pieces around unless there is a special lift in place for assistance.

Finally, finding the right type of stone for your climate can be difficult. Many specialty stones are limited to certain areas. As we said earlier, transporting flagstone is not cheap and will surely add to your overall flagstone price. While many stone companies are willing to help homeowners find a qualified replacement, this can increase costs.

Flagstone Maintenance, Repair & Its costs

Since most flagstones are relatively durable, maintenance is minimal, just like gravel or concrete. Nonetheless, tree roots, shifting soils, improper installation, thin stones or a poor base material can all lead to repairs. Consequently, there are a few maintenance items to be aware of:

  • Weeds
  • Stains
  • Cracks

Unlike concrete walkways, you need to look out for weeds between your flagstone pavers. If you installed enough gravel or sand, weeds should not grow in between your pavers. If weeds do grow up between the stones later on, they can be pulled by hand or controlled using natural weed killer.

Most flagstone walkways will fight off stains, but if your walkway sees a lot of foot traffic, regular sweeping to keep dirt, leaves and other outdoor debris from collecting in cracks is a smart idea. Additionally, consider pressure washing your walkway once a month when the weather permits or as soon as a stain hits. For hard-to-remove stains, try bleach and water. If that does work, you can find an oil cleaner for $15 at your local department store.

If you stick to a regular cleaning schedule, beware of chemical cleaners. It's best to stick to regular, simple cleaning solutions to avoid stains or discoloration.

Finally, always be on the lookout for cracks. As said earlier, the easiest solution is to replace the flagstone with one of the extra stones you purchased before installation. If it’s a straight, even crack, you can try replacing it with some extra gravel or sand.
