"We contracted with Mottern about 10 years ago to have a retaining wall built to replace a poorly constructed wall holding up the driveway. The wall was block on footer and it has held beautifully. When we original had the wall built, we decided against covering it with decorative stone. Jeff told us at the time that they would come back and add it if we ever changed our mind. Here we are ten years later deciding to add the stone. We called Mottern because the wall they built has had no issues (previous iterations of the wall had plenty of issues). The stone covering job was done quickly and professionally and looks great. If you're looking for quality, Mottern is for you."

"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."

"I had a really good experience. Day 1 was demo, day 2 was forms installed and concrete pour with finishing, day 3 was dressing up grass area. I am pleased."

"CM replaced 70 linear fee of my block retaining wall that was in serious disrepair from previous owners here in South Arlington (wall built circa 1961). CM was able to start work right away.  CM and I agreed beforehand that I would have the stumps removed by my tree contractor, but that contractor wasn't able to get his machine right up to the stump because of how it was situated on the slope.  Although removing the stump was not included in my contract with CM, they were able to get them removed anyway so that they could do their retaining wall work.  And they didn't charge me any extra for this! Plus, since I was cited by Arlington County for the disrepair of my existing wall, I needed for the new wall to be less than 24" (to avoid a permit). When CM was building the wall, there were a few spots that were going over a bit.  I raised this concern with CM and they were extremely attentive to my concerns and remedied the situation right away.  CM started only 2 business days after I signed the contract, which was great.  They cleaned up well, were very careful of my neighbor's property (which was very close to my project), and completed the project within the estimated time frame.  But more than anything, my experience with them showed that I could trust them with getting it done right and addressing my concerns - they really seem to know that well. Also, their pricing was very competitive compared to the four other quotes I received.

"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 hired Diversified Contractors to install a new patio, walkway and retaining wall at our home during the summer of 2017. The job consisted of removing an existing concrete patio and then installing a new patio and a 60-foot walkway using Westchester pavers. In addition, a 25-foot retaining wall incorporating a new PVC drainage system was installed under an existing deck. The job required a significant amount of landscaping and regrading of our backyard. Diversified Contractors completed the work on schedule and the men who performed the installation were courteous, professional and excellent craftsmen. The manager/owner came by each day to review the progress of the work. He was always accessible to address our questions. We are extremely pleased with the service and could not have asked for a better contractor to perform the work. The quality and design of the resulting patio, walkway and retaining wall have exceeded our expectations. We highly recommend Diversified Contractors to anyone who is considering having masonry work done at their home."

"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."

"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!!!"

"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."

"Julio and his team did a phenomenal job brining my backyard dream come true. He was able to correct a substandard and incomplete job done by a previous contractor. He is very communicative and has a creative eye. I had a front yard retaining wall, large patio, fire pit patio, outdoor kitchen and walkway installed. It turned out more beautifully than I could imagine. I can't wait to use it next season. If I need any other work done in the future, Julio and his team will be the first I call."
