"From the beginning Colorado Wall and Daniel, the manager made the project easy for me and the project. He explained the process. The materials are top quality and the price was reasonable. The retaining wall put in my backyard is beautiful and functional. I have to say I am impressed with the results and will hire Colorado Wall for future projects."

"I first hired Daniel and his team to scrape my front yard to get it ready for spring planting, and to plant four new trees. They did such a good job, I was thrilled to hire them right away to build a new retaining wall in my 100-year old house basement. They worked within the timeframe I needed them to, as I also was working with another company to replace my furnace. The wall came out better than I could have imagined! When I had some leakage problems with my sprinkler system, they came and worked on that, as well as replaced an old valve. They went above and beyond on my multiple projects. Daniel and his team are pros! I highly recommend them and look forward to using their services again! Thank you D&D!"

"Incredible job with our backyard masterpiece! Lots of retaining walls, a putting green, pavers, boulders, lighting, and textures that all work incredible together. I am very impressed with how the 3d rendering looks just like the finished product! For any similar project, I would highly recommend them!"

"Armando does great work and is fantastic to work with. He and his team cleared out our back and front yards and installed a retaining wall out front. The wall matches the house great and looks like it has always been there. Can not recommend highly enough!"

"Great looking variegated-colored block wall. They worked well with me and my ideas on the process of how to build the wall that I wanted. I was satisfied with the wall work that I am having them do a second project."

"Henry and team completely renovated our backyard. They installed a retaining wall, concrete patio, rock, sod and a portion of fence with a gate . They also trimmed up the trees and planted new perennials. Henry was very communicative throughout the process and we absolutely loved his designs and ideas. His team was very hardworking and fast without compromising quality. We even had a couple of neighbors comment on what a great job they were doing. We couldn't be happier with our new backyard. It's gorgeous!"

"Timberline Gardens Landscaping did a major construction of a three-tier retaining wall in our back yard area. We were specific on how we wanted the retaining wall be installed including using geogrid to tie back the wall system. We included two sets of steps to two tiers. The result was an exceptional retaining wall. The steps look terrific and provide easy access to two tiers. The crew was helpful in guiding us on the location of the wall installation and did an exceptional work during the installation. The crew was knowledgeableand professional, and their insight was invaluable. Shelly and Judy were patient with our numerous questions prior to and during construction and helped us with many decisions are the project progressed. Great work."

"As Fernando said to me, We are a well oiled machine and indeed they are. I'm very happy with the results. The crew worked fast but efficiently. Our project was a frontyard short retaining wall and a replacement backyard patio using BELGARD pavers."

Retaining Wall Installers FAQs, answered by experts

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

Options include concrete, stone, brick, and wood, tailored for specific design needs.

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.

While vinyl is the least costly material for building a retaining wall, the most cost-effective method is to use wood or concrete blocks for a DIY retaining wall under 2 feet tall. Wood is inexpensive but lasts 20 years or more with care. Concrete can cost a little more but is stronger and will last longer with less maintenance.

Regular inspection for issues like cracks or leaning and ensuring drainage stays clear.
