"Dan and his team of Clinton and Julie worked very hard installing a stone step to exit a room on the South side of my house. Julie also pruned a large and unwieldy Rhododendron in my front yard. Dan kept me informed as to when they would arrive and they were very polite and considerate. I am happy with the results. The new step is a wedge-shaped stone that will drain rain water and it provides a comfortable distance for stepping to the outside of the house."

"Dan and Julie did an amazing job. Not only is our new granite wall beautiful, Julie added a unique and personal touch that makes the wall even more special. They also added drainage to move rainwater away from the house and leveled and seeded the lawn. We are very pleased and plan to hire Tree Pirates again for a flower garden near the new granite wall and, perhaps, to build a stone patio near our deck. I recommend this company highly."

Retaining Wall Installers FAQs, answered by experts

Depending on who you hire to build a retaining wall, the average cost, including demolition and reconstruction, for a 50-foot wall that's 4 feet in height is between $7,000 and $24,000.

Sand and gravel are two suitable options for filling behind a retaining wall. If you’re building your own retaining wall, you’ll complete this part of the process—known as backfilling—after you finish laying the blocks. Make sure not to skip it—otherwise, you could wind up with drainage issues, which can cause your retaining wall to collapse.

The longevity of flood walls depends on how they were constructed, but most wood, gravel, and cement flood walls last 10 years. While aluminum flood walls may cost far more initially, they can be a good investment as they can last decades and will not be damaged by exposure to the elements.

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.

Small retaining walls still require a foundation of some kind, typically a concrete footing. This helps to ensure the wall is structurally sound and prevents the ground from shifting over time, especially during those winter freeze/thaw cycles. The footing helps spread the weight of the wall and the load it carries over a larger area of the ground, thus assisting with stability. This is true of small retaining walls, larger rock garden walls, and the like.
