Best retaining wall installation pros near Rosslyn, VA

"Great service from start to finish. We needed a large and tricky retaining wall building. Lazaro came in and advised on the best approach, and worked within our budgetary constraints. The work was completed on time and as agreed, and the crew were very careful and considerate in protecting the neighbor’s garden. We are very happy and will definitely be using Horizon for part 2 later this year !!!"

"We are beyond thrilled with the incredible work Patrick and his team did on our patio and retaining wall. From start to finish, the entire experience was outstanding. Our project faced some real challenges, including severe weather and even a snowstorm, but Patrick handled everything with strategic planning and constant communication. He always had a clear plan for when work could safely resume and how to stay on track. His professionalism and organization truly set him apart. Patrick and his crew were patient, hardworking, and genuinely kind throughout the entire process. They took the time to answer our questions and made sure we were completely happy with every detail before wrapping up. Their attention to quality and craftsmanship shows in the final result — our patio is absolutely beautiful, and we couldn’t be happier with how it turned out. We especially appreciate that Patrick offers a seven-year warranty and requires no upfront deposit. That level of confidence and integrity s"

"very well and I have actually retained the company for monthly maintenance"

"Garcia Landscaping Inc recently built two retaining walls and provided a slate overlay on our sidewalk. The company exceeded our expectations in every way - we could not be more pleased! The quote for the work was reasonable and the resulting products are of very high workmanship. The Garcia Landscaping team was polite and provided extra care in their work - for example, they dug up and saved a tree that I expected would be cut down. When the work was finished, they left my property immaculate. We would recommend them to anyone and would use their service again."

"We had onyx install a concrete sidewalk way and an asphalt driveway. They were fast, neat, and did quality work. Communication was great. We like that they stand behind their work with long warranty. They use much more materials to aid in longevity and durability of pavings and price was very competitive."

"replace patio and retaining walls"

"Shiraz and Abdul from Atlas GC were a pleasure to work with. Project Scope: Demo & rebuild 4' x 25' timber retaining wall w/ drainage stone, piping, etc. Rebuild wood fence on top of retaining wall Demo wood patio, install paver system & border river rock *They also worked with my HOA to install a walkway with stone pavers and an 8x8 timber staircase adjacent to the retaining wall Background: Our project started with the desire to demo and rebuild a failing ~4' timber retaining wall in our rear patio which extended beyond our property line into public space. Our HOA opted to build a stair instead of their section of the retaining wall. As you can imagine, this got a little complicated as it required a number of different reviews and permits from the city. I opted to manage the permitting myself, which involved a number of revisions to drawings and schedule delays. AtlasGC was very patient and accommodating during this process and also helped me work with the city to get the drawings approved. The city-driven changes to the design introduced added cost after their initial quote, but in order to keep the project from falling further behind schedule, they moved forward and absorbed the added cost. Communication/Professionalism: Shiraz and Abdul were very communicative and professional during the entire process. During the design evolution, Shiraz assembled a number of revised quotes which were very clear, timely and professionally assembled. We discussed a number of different options for the construction of the wall and he was very transparent regarding price, time, etc. During construction Abdul, Melvin and his crew were very respectful of the area and kept a clean construction site. Once started, the project progressed quickly and completed within the established timeframe. AtlasGC was also very patient and obliged to a couple of requests I made to make adjustments to their completed work per my personal preferences. They did this free of charge, without hesitation. Pricing: We had a number of contractors provide quotes on the project and AtlasGC was by far the most competitive. So competitive, in fact, that we decided to also have them hardscape our entire patio with a beautiful stone paving system. I highly recommend AtlasGC for their work, professionalism, collaborative spirit, and competitive pricing."

"Fast working, good quality, and easy to work with was our experience, the brickwork they did to fill in an old doorway was seamless - we could not have asked for better quality than what his crew did. They even came back the next day after the mortar set to powerwash the wall - everything looked great! We were very happy with their work and likely to use them for additional work in the future."

"Alpha Home Services was such a big help! I had a water leak incident that damaged the floor and ceiling of my home and Alpha Home Services was able to come quickly and open the ceiling and take out the dry wall. The first day they came they laid out all the plastic and closed off the damaged area and took out the dry wall to let air dry the foundation of the home. The next day they let it dry and came to check and spray to ensure there would be no mold. After they came again to install new dry wall and paint. They also were able to give me an estimate for all the damages and talk to my insurance company for the claim. I was able to get my claim and my home repaired in no time. Thank you again!"
