"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."

"The men that did the work related to the prepping the yard for the retaining wall, placing the rock and pavers for the walkway did a very good job and it really looked nice. I've worked in construction and building maintenance for over 50 years, so I know what's good workmanship and what's poor. The worker who did the framing for the new sidewalk, steps and porch was poor workmanship. Nothing was level or straight and I had to have the other crew correct the forms before concrete was poured. The guys that finished the concrete did an excellent job. Never let D&D workers connect the lawn sprinkler piping to your house water piping. They seem to be handymen, not real plumbers. Beside not installing necessary valves and fittings to winterizing the sprinkler system, all the copper pipe was installed crooked, under stress and not supported correctly. Overall, half the crew did very good work, the other half needs training."

"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!"

"I highly recommend Armando and his team! Heâ s come out to do a variety of projects at our home (building a retaining wall, installing a flagstone patio, updating barriers for mature trees and building up the grading from our home following foundation repairs). Each time, he provides a thorough estimate, clearly communicates timelines and has provided high quality work. We are very pleased with our experiences working with Armando!"

"The whole experience was easy. Ivan and Yuliana stopped by to asses the project, promptly got me a quote, scheduled the service and even called earlier to see if they could get it done sooner. Above all, the work performed was stunning. Ivan and his crew of two spent 8 hours on a small piece of my basement wall and the time they put into shows. I d recommend them to anyone looking for masonry work."

"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."

"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

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

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

A retaining wall can only function as a fence if it’s high enough on all sides to prevent someone from accidentally falling into the pool. However, most retaining walls retain dirt, which means their purpose is not related to safety. There would need to be nothing on the other side of the wall for it to be considered a fence, but in that case, it wouldn’t retain anything and would cease to be a retaining wall.  

Through proper drainage solutions and compacting the foundation soil.

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.
