How Much Does a Flagstone Walkway Cost?

Flagstone is a type of sedimentary rock that can be used indoors or outdoors as an accent piece or to create highlights when landscaping. If a homeowner plans to use flagstone as a material for a new walkway, there are several costs and options to consider. Flagstone is generally purchased through a landscaping contractor or direct source in order to get the best options and price. Because flagstone is a natural earth element, pieces are often irregular and jagged. Flagstone can be challenging to cut into small pieces, so it is often sold only in large amounts. One of the main costs of obtaining flagstone is delivery and installation because of its weight. Examining the overall cost of a flagstone walkway should be considered before the homeowner decides to make the final purchase. Here are a few things the homeowner should consider.

The Costs

  • The minimum cost of flagstone pavers to use in a walkway is about $3.90 per square foot.
  • The maximum cost is about $9.00 per square foot.

Types of Flagstone

There are hundreds of varieties of different types of flagstone and each one varies with color and style. Some of the most popular types for walkways are Tennessee Blue, Choctaw Regular, Choctaw Slab and Oklahoma Red Slab. Most colors are a natural tan, but there are countless varieties in blue, gray, beige, purple, red, gold and green. Many have light pastel colors that blend in nicely for walkways surrounding flower gardens. 

In some cases, flagstone is technically just a generic term for all sedimentary rock that is split into layers for landscaping and home improvement purposes. Sometimes, flagstone falls under other categories of stone such as sandstone, quartzite, limestone, bluestone, basalt, slate and travertine. 

When shopping for the perfect flagstone for an outdoor walkway, homeowners should look for certain qualities such as:

  • 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 is important to consider how much wear and tear the walkway 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 be high traffic throughout the seasons.

Cost Considerations

It is important for homeowners to understand that more durable flagstone pieces may cost more and increase the overall walkway or landscaping budget. Costs can also fluctuate depending on the type of open joints that are installed.

For gravel-filled walkways, costs can average around $10 per square foot. Using hand-mortared custom joints can cause the price to increase anywhere between $20 and $30 per square foot.

When considering cost estimates, it is important to think about if there are stone companies nearby. If the homeowner lives 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.

Including installation, the average homeowner should expect to pay around $15 to $20 per square foot for a finished walkway project. Prices can vary per location but contractors are very competitive with their work. The homeowner can also negotiate prices directly with stone manufactures if they are willing to do the work themselves.

Uses of Flagstone Pavers for Walkways

Flagstone has been used as paver since the early 1900s. It provides a natural look to the homeowner's patio area, making a top selection for walkways and paths both in the front and the back yard.

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 the homeowner should be aware of when speaking to a contractor or professional landscaping company.

  • Milled: Refers to cut flagstone that generates an edge on one or more sides.
  • Pavers: Flagstone cut into squares or rectangles.
  • Sawn bed veneer: Cut to a specific depth, leaving a natural surface on one side.
  • Ledgestone: Cut strips of flagstone that are flat and made for stacking on stairs or retaining walls.
  • 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.


Flagstone offers a natural beauty that highlights the walkway as well as the surrounding landscape. Homeowners who spend thousands on a new patio, pool area or landscaping do not want to skimp on the walkway or sidewalk leading to and from their home. Flagstone walkways offer elegance and a style that can 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 their home and landscape. This is a great alternative to concrete or gravel walkways that really don't stand out or create the curb appeal that many homeowners are looking for.


The biggest disadvantage to working with flagstone is the weight and irregular design. Prior to purchase, the homeowner may want to visit the distributor or see exact photos of the flagstone. This will help assure that the pieces are a good fit for the walkway project.

Flagstone has a 1 1/2-inch to 2 1/2 inch-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 85 to 100 square feet per ton of material. This can make it challenging to move pieces around unless there is a special lift in place for assistance.

Another factor that could be a disadvantage for homeowners is finding the right kind of stone for the project. Many specialty stones are limited in overall availability and shipping can be costly. Many stone companies are willing to help homeowners find a satisfactory replacement, but this can be costly.
