"I highly recommend NV Waterproofing & Foundation Repair! The work crew, Alfredo, David, and Javier were excellent! Alfredo Hernandez, the Foreman, kept me updated every step of the process, thoroughly answered every question I had, and addressed all concerns with expert problem solving and skill. These three men were in my home for a couple weeks doing extensive foundation and waterproofing work. They were always professional, courteous, and kept the work space clean. I was able to leave home for appointments with full confidence and trust in this crew. The sales manger, Brendan Feehan, was incredibly knowledgeable as well, and was able to solve every problem with my complex foundation and waterproofing issues. He was accessible to answer any questions I had throughout the process, and available to stop by as needed. Brendan is professional, helpful, and an expert in this profession. He's not just selling products. He understands the complexities of old and new construction"

"I hired JES to install a trench and sump system into the basement of a new house I purchased. After the job was completed, I noticed the cellar stairwell was pooling water. They returned and said that they didn't think that the drain was run direct to the sump as it should have been but they needed to open the concrete to verify. I also asked why there was no water in the sumps. They ran tests with water for 2 hours and didn't see water and tried to explain to me that it was expected since the water was running out around the drainage under the foundation. They even had a supervisor try to explain to me over the phone when I questioned it. It took them several weeks to return to fix the cellar drain and sure enough, the pipe was just run to under the foundation and not directed into the trench/sump. A repair team came out and busted up the concrete to correct it. In doing so, they saw that their trench was also not connected to the sumps at all, which is why I never saw water in the sumps and not the mysterious theory they tried to convince me of weeks prior. This is terrible that there is no inspection of work prior to covering it totally with concrete. Or further, there was no physical test of running water in the system to verify the sump works. The repair team that came out were wonderful and did everything correct. After this, I called 3 times and asked for a manager to call me to discuss this and never received a response. The salesman stopped answering my calls. As a note, after spending $30K on this upgrade to my house, it was in worse risk than prior to JES so if you choose them, be careful."

JES Foundation Repair (JES), A Groundworks Company, specializes in helping homeowners with their foundation repair, basement waterproofing, crawl space encapsulation, and concrete needs. Our top priority is providing high-quality home repair solutions and personalized service across Virginia and Maryland. With fully trained technicians, industry-leading products, and nationally backed warranties, JES is here to restore your foundation or crawlspace.

"JES left my home in worse shape and will not return my calls to come repair the damage left. I reached out to them to install a joist support system under my kitchen so that I can renovate this year. There were floor joists under the back door that had been cut during a renovation about 30 years ago. JES installed a jack system but then left my foundation under the door where you can literally see daylight from the basement. I brought this up to the crew before they left late Friday night (they worked long hours just to ?finish? without even asking me if it was okay to trap me at home that late), and the lead just shrugged at me. Shortly after they left, it rained, and sure enough, water poured into my electrical room and all over the freshly poured concrete. I called Friday night, sent an email and text with videos, and called today 3 times. Each time the ?production manager? is ?busy.? Before this, they were perfectly capable of blowing up my phone to see if I could schedule sooner."
