"Had a retaining wall done? Eric was great in keeping me informed of all steps up to the very end and was easy to work with. His team did an outstanding job and the wall looks great. It is nice to have a company that shows pride in its work and cares about the customer. I highly recommend them."

"I had a persistent drainage issue in one corner of my flower bed—flooding so bad I assumed a sprinkler pipe had burst. Dave and his crew came out, dug up the area at no charge, and confirmed that wasn’t the case. He took the time to properly investigate and diagnose the issue, then installed a French Drain that completely resolved the problem. As always, the work was done expertly, efficiently, and to the highest standard. This is exactly why I’ve trusted Dave with my landscaping for the past 7 years. He treats every project like it’s his own home—always recommending what’s actually needed, never upselling or cutting corners. In an industry where it’s easy to exploit customers’ lack of technical knowledge, Dave is the rare pro who builds trust by consistently doing the right thing. We’re long past the point of me asking for bids or details—he tells me what should be done, and I give the green light, knowing it will be done right. SIX STARS!"

"We hired Patrick Concrete to install a concrete patio around the front of our house with a connection to the two front doors. Patrick and his crew were very courteous and professional. We talked with him about some specific design considerations that we wanted. He helped us with some preliminary work, made some very practical suggestions, and gave us the end product we had asked for. His price was reasonable. He started the project right away and did the pour as soon as weather permitted. I would use Patrick Concrete again and recommend them to others."

"Big shout out to Alex, Gami, and the crew at Forest Landscape for our latest retaining wall and patio project. They were responsive and professional, and communicated with us throughout the project. They could not have been nicer or more hard working. We are very pleased with the work, and highly recommend Forest Landscape."

"Flintstone Hardscapes LLC removed an old rotten deck and framed and built a beautiful concrete patio in my back yard. The space was small and they had to remove part of a fence to get access. They were wonderful and even replaced the fence overnight so my dog could not run off. I highly suggest you give them a call at 503.837.9294 to get a quote for your next project."

"Israel and his team were great to work with and I am really happy with both of the projects they competed for me. They replaced an old, failing retaining wall with a beautiful stone retaining wall with a French drain behind it. I showed Israel pictures of what I wanted it to look like and his team did an amazing job making my vision a reality. They were careful with my existing plants and landscaping and went above and beyond by moving and repotting a shrub that I was unable to move by myself before the work began. They also replaced parts of my backyard that had been removed by neighbors and built a beautiful new fence and gate out of cedar. They did an amazing job matching the style of the existing fence and my yard looks so much better now. I am so happy with everything and I would work with GI Landscaping again anytime!"

"A crew of two came to help clean up the seriously insane amount of gravel and weed fabric strewn throughout our property. The team showed up on time, hauled and dug everything out, and made everything level and nice to start rebuilding good soil. Hard working, finished within projected project timeline, and kind folks - 10/10 would hire again!"

Retaining Wall Installers FAQs, answered by experts

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.

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. 

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.

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.
