"Eric and his crew are absolutely outstanding in every possible way. They tore down a very old rock wall and installed a beautiful new retaining wall. They also installed a new fence and three gates for me. All this in only one week, and beautifully done. The pricing was reasonable, the work careful and precise. In the future I will definitely be recommending them again and again (in fact, I already have)."

"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's Masonry and Concrete to remove our old driveway and install a new driveway. The entire experience was excellent from start to finish. The crew was professional, showed up on time and communicated clearly throughout the project. The owner was present each day giving us added confidence in the quality of the work. The project took 4 days and also included masonry work on a brick pathway which turned out beautifully. I'm very careful about work done on our house since it's on the National Registry for Historic Homes and they exceeded expectations. The finished driveway looks fantastic-smooth, properly graded and built to last. You can really see the quality in their workmanship. The pricing was fair and clearly explained and the finished work was absolutely worth every dollar. It's not always easy to find contractors that follow through like this. I would definitely hire them again and recommend highly for any concrete or masonry work."

"Job took two weeks end to end. The job was complex and involved tree removal, demolition, and then construction. Alex let us know what to expect and raised issues and decisions in an efficient manner. Noe and Gildardo were punctual, hard working, and took great pride in their work They worked through some wet and nasty weather and it didnt slow them down. The precision stone cutting they performed to build the wall properly really made a difference. The end result is amazing and we are very happy with the result."

"The Crew did a great job. They were timely, finished on schedule and were very professional. They installed turf at our preschool and the kids enjoyed watching them work. They went above and beyond to clean up after the job was complete. When we noticed something seemed off with part of the turf they fixed it right away without question and didn't stop until the job was completed and we were 100% satisfied."

"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!"

"G.M.G Landscaping and Maintenance was great to work with, upon 1st visit they brought samples of different turfs related to my project and got me a bid really quickly. Provided me with things I needed to submit to the HOA for approval and the work was completed on time and looks fantastic. Thank you Rosie and Team!"

"George and his crew work very hard and do an excellent job. We made changes mid-project and they accommodated us without complaint. The crew showed up early and stayed late. George is a great communicator and his crew is respectful. We got a two car driveway install done in two days. I highly recommend them."

Retaining Wall Installers FAQs, answered by experts

Failure to compact the soil during construction is the most common cause of leaning retaining walls. In addition, poor drainage can lead to excessive water pressure behind a retaining wall, pushing against it until it begins to move forward away from the soil it is holding back.

Rebar is a steel support that goes inside concrete to prevent structural damage over time. Concrete is susceptible to impact, weight, and tension. By inserting rebar into the concrete during the installation, you can help extend its lifespan and avoid hazardous situations where the foundation of your home gives way to tensile forces.

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

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.  

Costs depend on material type, labor rates, and additional features like decorative finishes or reinforcement.
