Retaining Wall Cost Factors

While the material, height and length will contribute more than anything, there are other remote factors that can increase or decrease your retaining wall cost:


Sadly, some areas of the country see more extreme weather than others, ranging from tropical storms to earthquakes. If you live in such a location, your retaining wall may require greater structural reinforcement and extensive waterproofing, both of which increase the cost to build a retaining wall.


Certain landscapes and existing retaining walls require more excavation. For example, it’s much easier to remove dirt if no retaining wall is present versus replacing an existing wall with stone and boulders already in place. If you have a retaining wall and want to save some cash on a masonry pro, remove as much of the old wall as possible.

Type of Soil

All soils were not created equal. Some soils can hold more water, while others are only ideal for very short retaining walls. In addition, bedrock, used for taller walls, can drive up your total cost.

Some homeowners install steps for their retaining walls. Whether it’s a safety precaution or not, this project will require more materials and time and as such, raise your total retaining wall cost.


Retaining walls can be placed all over the front or backyard, however, the easier it is to access, the cheaper your project will be. Stone blocks and bags of soil are heavy. If a mason can drive the stones and bags to the exact location, the total installation time drastically reduces. If not, the job gets that much more difficult, increasing your total retaining wall price.

How Much Does a Retaining Wall Cost?

A retaining wall is more than just another decorative element or landscaping feature. These walls serve an important function: to prevent ground from slipping and sliding. Though decorative in nature, retaining walls are a must for some areas.

Nevertheless, the big decision revolves around cost. See the full cost breakdown below. If you need some assistance with your retaining wall installation, we can help you get in touch with masonry pros near you.

Cost Of Retaining Wall

  • Wood Retaining Walls: $15 per square foot
  • Interlocking Concrete Retaining Walls: $20 per square foot
  • Natural Stone Retaining Walls: $25 or more per square foot

The cost of a retaining wall depends on the material chosen, the overall height of the wall and the length of the wall. Wood retaining walls start at $15 per square foot, while concrete retaining walls start at $20 per square foot. Homeowners interested in using natural stone will find that those stones increase the cost to $25 or more per square foot.

In addition to the materials used, the job also requires excavating the ground and removing any dirt or surface materials from the space. This can add a few thousand dollars to the job, depending on the length of the wall. Though experts generally recommend that retaining walls sit no higher than four feet without any additional support, it’s possible to have a retaining wall of up to 10 feet high. These taller walls can cost nearly $20,000 while a six-foot-wall can cost around $13,000. Decorative retaining walls and those that serve no real purpose generally cost less.
