How much do retaining walls cost?

This will always be one of the first questions a retaining wall shopper will ask when starting their retaining wall installation journey, and for good reason.

We understand that price matters!  

Why does price matter?

Price often dictates what material your retaining wall is going to be made out of, what the wall will look like, if there are any add on’s (plants and lighting) and what the remediation of the project looks like.  

As a consumer, you need to know what your initial budget is and plan for any problems that may occur with the retaining wall build along the way. This is true for any size and type of retaining wall you are thinking of installing.

It is tough to answer this question right off the bat because retaining walls have so many options on how they are built, and variables like access to your space affect the price of the build.

It’s tough to know the price of a retaining wall project unless you as the homeowner have figured out exactly what you want. (Think of what you want the final project to look like).

Throughout our years in the retaining wall industry we have provided answers to this question multiple times.

Our goal is to educate homeowners on all things related to retaining walls, even if this means that they end up choosing to go a different route with their build.

Please keep in mind that these prices are estimates based on a certain scope of work. Your yard may come with challenges that obviously cannot be included in the price of the build, or you may want add on’s that change the scope of work, therefore, changing the price of your retaining wall.

Remember, prices can vary drastically based on who installs your wall, and what product you choose for your wall build.

Now, let’s get into the good stuff!
