Retaining walls have a greater purpose than just serving as a decorative feature of your landscape. The main function of a retaining wall is to hold the soil in place, preventing erosion and providing stability to sloped yards. Pittsburgh and most of Western PA has an abundance of yards and properties with uneven terrain, making retaining walls a necessity in many cases.

When it comes to building a retaining wall, a there are a variety of factors that go into determining the cost. Three of the main contributors to the overall cost of a retaining wall are the materials used, the height of the wall, and the length of the wall. However, there are a few other factors, depending on your property’s landscape, that can influence the price:

Location of the retaining wall

If the area in which you are building a retaining wall requires extensive waterproofing or more structural reinforcement than normal, it will add to the cost of your retaining wall.


The accessibility of the area

Areas that are more difficult to get to will make moving the materials necessary to construct the wall more difficult, thus increasing the cost. Areas that are easily accessible will reduce the total installation time, which will directly affect the overall cost.

Extra features

If you are looking to add special features to your landscape by incorporating them into your retaining wall, such as steps or columns, the additional materials and labor will raise the total retaining wall cost

Excavation requirements 

The amount of excavation required varies with each job and can significantly contribute to your retaining wall’s final cost. Replacing an existing retaining wallinvolves removing the materials that are already there, as well as reinstalling the new wall. The excavation required for a new retaining wall installation will depend on the location of the wall as well as the type of soil.

As a finished product, retaining walls are not only an attractive feature, but a necessity to the health and stability of your property.
