"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Lorenzo and his team did an excellent job of building a replacement concrete footing wall to support our stairs going down to the water. They did an excellent job under tough conditions. They were both on time and very neat."

"Work performed on designer block berm wall was outstanding. Ran into an issue where they started installing the wrong type of designer block then what was originally requested. I did not notice until after the installation started. I brought it up to the owner/supervisor and he made the correction with no resistance and no additional cost to me. The project came out great and I am looking to have them perform more landscape design projects for us in the near future. FEI has been our general landscape maintenance contractor for 15 straight years. The edge, in my opinion, FEI has over any other landscaper that I could bring in is their personable and organized office manager. Her responsiveness to any needs, or concerns, which I may have regarding my lawn care service is handled professionally and efficiently."

Retaining Wall Installers FAQs, answered by experts

Each design is different, so we can’t say definitively if you’ll need a dedicated drainage system in place for a two-foot retaining wall. However, you can likely skip the drainage, as this project is typically served for walls that are 4 feet tall or more. Even with a relatively low wall, consider drainage if you are building on top of clay or poor-draining soil types or if there are buried water sources nearby, like a well used for other outdoor garden projects.

Costs range from $5,000 to $15,000, depending on size, material, and design complexity.

Railroad ties can be good for retaining walls, but it depends on the area. They have a desirable rustic look and are durable. The problem is they’re treated with creosote, a preservative the EPA says poses a risk to humans and wildlife. Over time, the preservative seeps out of the wood and into the ground. Many areas have banned the use of creosote-treated wood on residential properties. If your area does allow it, never use railroad ties near an edible garden or drinking water source. Instead, use wood that’s treated with an EPA-approved preservative or a wood-alternative composite material.

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.

Proper design and construction prevent erosion and add structural stability to landscapes.
