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.
