They were able to lift and level my concrete slab back to exactly where it was originally! This saved me a big chunk of money.

It was a pleasure to work with DMV Foundation Solutions & they truly provided high-quality customer…read moreservice. From the initial phone call with Logan, to the consultation with Yos, they listened to our concerns/requests & communicated things clearly. Yos was punctual, friendly, and efficient in his evaluation. He generated a detailed report outlining his professional opinion regarding minor cracks in our poured concrete foundation wall & even provided recommendations for preventative maintenance. Five stars!

Late in the summer of '24, we started to see a few cracks developing in our home. No big deal -…read moreit's 70+ years old, cracks happen. And then they kept happening, getting larger and spreading throughout the entirety of the house, and we could no longer open the doors in the basement and 1st floor on the south side of the house. Alarmed, I called a civil engineer and had an assessment done. They ascertained our house was sinking, particularly in one corner, and recommended ~30 push piers around the perimeter and up the centerline of the house... for over $100k. I literally laughed at him and asked him who he thought I was that he thought I could afford that. I called a few other places and got questionable assessments, and then I spoke with Yos from DMV. What a breath of fresh air. He was personable and honest. He recommended we get a 3rd party civil engineer to produce a report with drawings that I could use for any foundation company - even if I didn't go with DMV. We (finally, after a loooong delay on the civil engineer's part) got the report and drawings, and Yos and his team began work in early January to install ~10 helical piers on the sinking corner of the house. It was a pretty invasive project, but his team was fantastic. Fast forward 5 months and the cracks have stopped appearing, with a number of them even closing. We are very satisfied with the work DMV did for us, and are particularly pleased with their honesty. Where one company tried to sell us an overkill solution for six figures, Yos was upfront and told us what we really need - to address that affected area and revisit others if they end up being an issue - for roughly a quarter of the other company's price. That sort of honesty and pricing earns a permanent spot in my trusted contractor list.

I give Basement Masters Waterproofing a gold star ++ . I wanted one side of our house…read morewaterproofed. That side gets a lot of rain and I did not have gutters there. I contacted 4 companies and only 2 responded. I did my research and found Basement Masters to be a very reliable company. Their quote was a fair price for the work that had to be done. The quote included a written summary and pictures of what to expect. The company is easy to communicate with and is responsive in answering questions. The crew came out one day and finished the next day. (They did a LOT of work). All of them were hard workers, courteous, efficient in their job and answered all the questions that we had. Walter was our point of contact but all the workers were excellent. I am happy, my house is happy, and I would recommend Basement Masters Waterproofing to anyone because I think they are top notch.

after much searching, I found Basement Masters. So happy I did. Long story, short...I have a…read more French drain in my basement that appears to have a leak. System has lifetime warranty, but the company who installed it many years ago suggested I have a plumber and a foundation specialist check it out before they come. If not there their issue under the warranty, there's a hefty charge. I contacted Randall, the owner of Basement Masters, who came out promptly, looked at old system, discussed concerns with warranty coverage I might encounter, and found no foundation cracks. He kindly offered to have me call him after the old company comes out to assess the issue. All done for no charge. You'll not do business with a more honest, reliable company. I highly recommend Basement Masters and Randall ,

Marty and his partner went the extra distance, the void beneath the slab was so bad that it took two visits but they got it done and in this sweltering heat both times. Got two estimates and they were the best value and quality. Thank you for sending a great crew, I feel bad that I didnt catch the young guys name he was a wonderful partner to Marty. Trust your homes repair to JES and they came up from Ashland VA to Stafford.

My experience with JES Repair was frustrating and ultimately disappointing…read more The project itself was completed on schedule, but the quality and planning of the work left a lot to be desired. The beam repairs appear to have been completed in the easiest way possible, with little consideration for the work that would need to happen afterward. The crew cut the subfloor approximately three inches away from the walls and left it unsupported. As a result, my flooring contractor had to tear out two sections of flooring and replace the entire subfloor in those areas because the necessary repairs were never addressed during the original project. Even more frustrating, JES only opened a limited section of the floor instead of exposing the entire affected area. Once the flooring contractor had everything opened up, additional damaged wood was discovered that now requires even more repairs. Since JES was already working in that area, it is difficult to understand how these issues weren't identified or why the floor wasn't opened far enough to properly inspect the entire section. Addressing everything while the area was already exposed would have saved significant time, cost, and disruption. The inspection process was another major disappointment. The county inspection failed and was rescheduled without anyone from JES informing me ahead of time. I was then told that no one from JES would attend the reinspection and that it was between me and the county. As a homeowner, I'm not a contractor and shouldn't be expected to answer technical questions or represent the company's work to the building inspector. I hired JES expecting professional workmanship, thorough planning, and support through the entire process. Instead, I've been left coordinating additional repairs, paying for work that could have been avoided, and handling inspection issues that should have been managed by the contractor. Based on my experience, I cannot recommend JES Repair. UPDATE (07/08/2026): I connected with the resolution team and are working through the issues in a positive and constructive manner.

Working with GLM was hands-down the best experience I have ever had with a contractor. I'm forever…read moregrateful that a neighbor recommended them. We had some drainage/waterproofing issues that needed addressed, and when I found out the scope of their skills, we also hired them for a laundry list of things I had on my wish list since moving in a few years ago. These folks did it all for us! For starters, they repaired a brick wall in our front yard, installed a new sump pump drain pipe and exit, re-worked some existing exterior waterproofing that had been done sloppily in the past, and added a new concrete pad and drain by our back door. They even helped us track down an underground gutter leak and replaced the broken pipe. The showpiece job, however, is the stunning stone retaining wall, that they meticulously built by hand, across the back yard along with the new cement parking pad and stamped concrete border tapering it to our existing drive. The pictures don't do it justice (attached is a "before" photo for reference). Everything was done with great care and precision, using high-quality materials. The owner of the company, Deborah, was a gem to work with. She is super-passionate about the environment and the quality of work her company does. We worked with Gerardo and he was also fantastic. He had great ideas and suggestions in terms of practicality and design. He was also flexible with a few adjustments along the way. You can tell that these folks are truly experts in their field and take great pride in their work. I would hire this company again in a heartbeat!

Deborah is really inspiring and great professional! We called her for a quote and she was…read moreresponsive, communicative, and really informative. I really liked that she sent calendar invites for her appointments and was really organized. We didn't end up working with her since our scope of work changed but I really admire the way she does business.
