Best retaining wall installation pros near Dulles, VA

"The front yard of my townhouse was a mess. I had mostly weeds and dirt and a burning bush and tree that was out of control. Juilo and his crew came in and within two days, removed the burning bush, trimmed the remaining bushes, trimmed back the tree and installed a beautiful retaining wall, with river stone and perennials, and added new sod. My front lawn is now beautiful, thanks to ET. General Contractor, Inc. I highly recommend them for your landscaping project!"

"The contractor and crew did a fabulous job of installing a permeable paved driveway and retaining wall. They were respectful of me, my time and property. They kept me updated and explained each phase of the project. I’m very very pleased with the company and the completed project. I highly recommend this company and would definitely use them again."

"Great job putting in a concrete slab with retaining wall for our swimspa (complete with drainage). Very happy with Robert and team! Beautiful work and reliable services. Thanks again!!!"

"Great drawings and very professional. I’m putting this project on hold until the fall. It appears there’s other items on the foundation wall that needs to be taken care of before the landscaping company can do their job"

"We had a great experience working with Mike and his DC Patio crews. Relationships are important when entering into a big project, and we clicked right away with Mike. During his initial site visit, he listened to what we were looking for, provided suggestions for us to consider on details where we were undecided, and really took it all in as it was a large project wrapping around three sides of the house. He was flexible regarding our desire to source some of our own materials, and provided a detailed, comprehensive estimate that was very competitive relative to other proposals we received. Our project was delayed due to our preferred materials being unavailable as the factory shut down for two months during the initial COVID-19 lockdowns, but once we had a delivery date, DC Patio was able to get us on their schedule and get started. The crews were great: respectful, courteous, polite, tidy. Edgardo and Victor were here almost everyday, and Henry, Marvin, Donaldo, and others joined depending on nature and scope of the day's work. Mike usually came out in the morning to go over the plan for the next day or two and walk through any design decisions that were needed. In the course of about five weeks, the crews were able to remove two old walkways (including jackhammering out a set of concrete steps), add 4-10 inches of soil all the way around the house to create slope for drainage, divert 5 downspouts with underground pipes and pop-up emitters as well as two catch basins, build the crushed stone base for the new walkways and multi-level patio, install a small retaining/seating wall as well as two long, curved steps between the levels, build three small sets of bluestone steps into the house, and install two curving paver walkways, three pavers circles, a fire pit, and a large paver patio, totaling almost 2000 sq ft! And they moved a few large plants and installed some landscape lighting at each stair riser to boot. The last step was to seed the area around the patio for grass, but due to it being early July, we all expected that it may be too hot for the seed to take root even with daily watering. Mike anticipated this and planned to send a crew back in the early fall to overseed, which he did proactively without prompting. The grass seed took hold the second time and now we are all set to enjoy our new spaces this spring! We always like to support local business who take care of their customers AND their employees, and Mike's commitment to communicating with his crews in Spanish is clearly appreciated. The commitment goes both ways - we talked to several of his guys who have worked with him for many years. I would highly recommend considering DC Patio if you're in the market to transform your property with beautiful hardscaping."

"They were amazing. I mean it really looks good. I think that if I paid less, it might not have looked quite as good. They were really professionals that knew what they were doing. The way they did the retaining wall just looks really really nice. I would give them higher than an A in some way. They were so nice. There were so many of them, and they worked so fast. They were experts. The salesman was also excellent because he took into part what I was trying to convey, and he designed it. He kept showing me, and we kept sort of tweaking it. You want that. They were punctual. They were scheduled for a week or so later, and I called and asked if they could come earlier because they had an opening in their schedule. They like to keep their crews working constantly, and I had really wanted it done as soon as possible. So I agreed. They came and they were right on time. They worked very hard. They always cleaned up after themselves. I mean so many leave a mess or leave a part of it undone. Plus, it just exceeded my expectations of how it looked in the end."

"They did an excellent job repairing stone veneer on a retaining wall that had been damaged. They did a good job matching the repair work to the undamaged stone and it looks great and you can't tell it was damaged. After the job was complete they cleaned up the job area. They weren't the lowest price quote I received for this small job but they showed up and got the job done."

"Outstanding! The workers arrived in a timely manner and did an outstanding job. I would definitely hire this contractor again."

"They laid sod, built a stone wall, and implemented a drainage solution. They did an amazing job and very quickly. Other companies hadn’t even called back before they performed the work. Well done!!"

"I reached out to Cassella Landscaping to build a new retaining wall and patio in my back yard. I got estimates from six different companies before choosing Cassella. I will explain why I chose Cassella over the others, and why I am so glad I did. They were amazing! I did my research and read so many reviews. Cassella clearly had highly satisfied customers. Elijah, the owner, personally came out to talk to me about my project. From the start of my interaction with Elijah, I could tell this company was different. He listened to what I wanted done and my concerns about cost just like the other companies. But then what happened next was what made Elijah stand apart from the rest. I had made it clear that I was concerned about price and wanted options to consider how much of my project I could actually afford to do. He took the time to ask me questions to understand why I wanted this space, how I planned to use it, and which parts of the project were most important to me. And then he not only gave me options, he helped me refine my vision for the space to help me see what I could get done within my budget. He clearly cared enough to not just get the job, but to make sure I would be happy with the outcome. He was the only company who also told me that he would have one team working only on my project from start to finish. And he offered a warranty. The process of working with Elijah and his team was great all the way through. He answered all of my questions in a timely manner, and he communicated frequently. He had a team that was with my project from start to finish. They were hard workers, polite, and kept everything as clean as possible throughout. They cleaned up everything at the end, as well. They started when they said they would, and they completed the project right on schedule. The final project looks amazing. I couldn't be happier. I can't wait to get my new patio furniture so that we can start enjoying this new space when the weather is nice. My finished project is a retaining wall (3 feet tall by 40 feet wide) and a patio (12x24 feet) with beautiful pavers on both. The landscaping around the wall and patio was just what I wanted with river rock and plants. He transplanted the young trees that I wanted to keep and helped me pick out plants for the rest of the project. I had not imagined including lighting, but Elijah suggested it, and the lighting is beautiful. I also had a walkway installed that matches the paver patio style. It all looks so great, I am very happy with it. I highly recommend Cassella Landscaping. Elijah and his team were such a pleasure to work with and the finished project looks amazing."
