" Josh 's communication skills were impressive especially when most contractors don't find the time to keep their clients aware of delays , schedule changes or simply retuning calls. The work was completed on schedule and there were no surprise fees. We will definitely hire Josh again- he's intelligent, personable and a hard worker."

Retaining Wall Installers questions, answered by experts

DIY is possible for small projects. Professional installation ensures structural integrity and durability for larger walls.

Most retaining wall installations can be finished in one to three weeks, but the timeline varies based on factors like wall size and material. The local climate and major weather events, such as storms or flooding, can also extend the project's timeline, as can any holds ups in the permitting process.

Yes, to build a retaining wall, a permit is required. Similarly, any repairs or modifications to an existing retaining wall require permits. If the planned wall measures higher than 4 feet, most municipalities require designs and permits come through a licensed engineer. In some locations, if the wall is shorter than 4 feet, a permit may not be required. For the requirements in your area, contact your local government.

Installation typically takes 1-2 weeks, depending on the wall’s size and site conditions.

Poured concrete is likely the cheapest way to build a retaining wall, as this material costs anywhere from $6 to $8 per square foot. The next best budget-friendly option is to use landscaping timbers. These timbers are great for DIY projects, as they don’t require tools to successfully build a retaining wall. Landscape timber costs around $10 to $14 per square foot. Depending on your chosen garden style, you can also go with natural stones or concrete blocks. Natural stones can be expensive if you buy them, but they’re a lot less costly if you can source them from your property.
