Interlocking Brick Patio Prices

There are many advantages of installing an interlocking brick patio. Other than the traditional look so many love, interlocking bricks withstand extreme weather such as freeze and thaw cycles better than poured concrete or bricks laid with mortar. Perhaps the biggest pro of an interlocking brick patio is that it will last 40 years or longer with only minimal maintenance required. Now see what it costs.

The Costs 

  • The minimum cost of an interlocking brick patio is $6.62 per square foot.

  • The maximum cost for an interlocking brick patio is $11.23 per square foot.

Interlocking bricks come in different grades. The basic grade of bricks is less able to withstand weathering while the highest grade of exterior bricks can withstand severe weather conditions. Having an interlocking brick patio laid by a landscaper or general handyman will cost less than hiring an experienced mason to do the job. A landscaper or handyman's labor averages $20 per hour while a mason may charge $70 or more per hour. A mason may be able to create a better looking end result; however, including intricate patterns and complex designs that require extensive cutting and shaping of bricks. A landscaper or handyman's services are sufficient for a basic interlocking brick patio design. If the area where the patio is to be built requires leveling, this will add to the project cost.

Additional substrate materials such as soil, crushed stone or sand may add an additional $1 to $3 per square foot for the overall project cost. Trees, cables, pipes or concrete that are in the way of the desired patio location will need to be rerouted, removed or demolished, which will also increase the cost of an interlocking brick patio. Once the patio is laid, it will need to be sealed to prevent damage to the bricks. Application of sealant to the brick patio adds another $1 to $2 per square foot to the project cost.


Modern standard bricks are controlled in size by the American Society for Testing and Materials and measure about 8 × 3 5⁄8 × 2 1⁄4 inches (203 × 92 × 57 mm). Interlocking bricks may be made of materials including clay, calcium silicate or concrete.

Clay bricks are the most common type. These bricks are created through one of three process types: soft mud, dry press or extruded. The soft mud method is least expensive, uses 25% to 30% sand in the mixture and is fired at a temperature of 900 to 1000 degrees Celsius. Dry press bricks use less sand, more clay and a longer firing time than soft mud. Extruded bricks are created with voids or holes in the center and are used primarily as a structural brick. The color of the finished brick varies based upon the location where the clay was sourced as well as the firing temperature. As firing temperature increases, the finished brick progresses through dark red at 1000 degrees Celsius, purple at around 1150 degrees Celsius and then brown at a temperature of 1300 degrees Celsius. Calcium silicate bricks are created with a mixture of lime mixed with natural quartz, crushed flint or sand along with minerals that leach color into the mixture. They come in shades of red, brown and pastel colors. Concrete bricks are uniformly gray in color and are the least common type used for interlocking brick patios.

Advantages of Interlocking Brick Patios

If one brick chips or cracks, it is easy and inexpensive to remove the damaged piece and replace it. Clay bricks are often made of locally sourced materials. In the winter, an interlocking brick patio can be shoveled the same way as a concrete sidewalk. In the summer, the bricks can be washed off with a garden hose. Interlocking bricks can be arranged in many different configurations to create a patio. The various color options also add to the visual interest of the finished project.

Disadvantages of Interlocking Brick Patios

While many home and property owners prefer interlocking brick patios, there are some disadvantages to the interlocking bricks. If clay bricks aren't sealed, frost can seep into the brick and cause it to crack or chip. Unless the soil beneath the patio area has been properly prepared, some settling may occur. This can cause unevenness and safety hazards. In earthquake-prone areas, the weight of an interlocking brick patio may require structural reinforcement underneath the patio and along its borders. An interlocking brick patio may be more costly to install than patios built of other materials such as stamped concrete.

Other Uses of Interlocking Brick Patios

Interlocking brick patios have many uses for residential and commercial properties. Walkways and paths may be created out of interlocking bricks and connected to the patio. The interlocking bricks can also be used to build a driveway, steps or a porch that coordinates with the patio. In commercial buildings, interlocking bricks may be used in vestibules, unheated enclosed areas and along walkways to create indoor patios that withstand heavy foot traffic yet look attractive and traditional.

Considerations for Interlocking Brick Patios

When clay bricks are used on a patio that will be exposed to grease and oil, the bricks will need to be sealed every two years to resist discoloration. To clean any type of interlocking brick patio, a mixture of 10 parts water to one part dish washing soap can be used to remove dirt and other grime. Home and business owners should avoid putting calcium chloride on brick patios. This type of deicer can cause efflorescence of the bricks.
