Foreman David Gaskins came to our house after our basement was waterproofed. Some water came in from a heavy rain and and a repair we were promised was not done. David inspected the waterproofing work and found what needed to be done to be sure water would not come in again. This has been a very stressful time for us but David has been wonderful and gone above and beyond to keep in constant touch with us and coming up with a plan on how to make the corrections. We are just so thankful that he is the one that came to our house to look at what the problem was. Your company is lucky to have him.

My entire experience with JES has left me completely satisfied. My project was a two day job scheduled by the Inspecter Ryan at the time of his initial visit and the signing of the contract. The foreman, Gregory Shock showed up on time on the days scheduled, April 21st and 22nd, 2025. His attention to detail was incredible and his willingness to answer questions and explain all of the process was so much more than I could have expected. Both during the project and upon completion, he showed himself to be personable, professional, knowledgeable, and able to go above and beyond to make sure that both my wife and I were fully satisfied with the work he performed. His clean-up was thorough. making sure that anything that he disturbed was left as he had found it originally. he even took the time to answer questions before he left related to the warranty on the work that he had performed. Thank you JES, Ryan, and most of all the guy that really did the hard work, Greg

Mr. Rudy Gonzale, Superintendant at the JES in Bristow, VA, came to our rescue when my husband and I called about a foundation water problem. Rudy showed up in a very timely manner. He was very polite, professional, and very knowledgeable. He explained things in a way in which we could understand what was going on with the issue we were experiencing. Rudy listened to and understood our concerns and in a very professional manner he demonstrated empathy and assurance that everything will be alright. Even though my husband and I had never met Rudy before we felt he treated us like he would a family member. Rudy was a blessing to us. He was true to his word that "Everything would be alright". I highly recommend Rudy and his team who assisted us in resolving our problem. We could go on and on about Rudy with the highest accolades because the words Thank You to Rudy doesn't seem adequate.

Had a problem with our hot water tank not producing hot water. Our technician, Mike H., was straight forward and gave us our options. He even said if we wanted to find other prices that they'd price match (from certified companies). We decided with getting a new tank and thankfully we did because it started leaking while they were working on it. They came Tuesday to do their initial inspection, then came Wednesday to install out new hot water tank! Very happy with the service and friendliness. He also kept shoe covers on and made sure to keep doors closed since we have pets. Highly recommend

To be honest, I have been having issues with JES since we moved into our house. I always felt like we were trying to be scared into buying a service. However, Ethan came out today and he was the first technician that made me feel like I was actually heard and did exactly what I wanted him to. Plus, he was seriously so happy and a big ball of sunshine! Ethan actually changed my perception about my past service calls with JES. If I had to recommend a technician from JES, it would definitely be Ethan!

The inspector came out two times and was professional and thorough. He didn't a great deal of time walking me through options and modifications and discussing the process and timeline for doing the work. Follow up scheduling was very easy and convenient.

The crew that worked with us on our project was respectful, cordial, professional, and courteous. A big thank you to Steven Marshall, Deron Kelso, and Micheal Burrel for a job well done! They kept us informed every step of the way on their work. These guys went above and beyond to aid us in moving a few things that we were unable to move on our own. They worked quickly and effectively, to earn our business again.

Time will tell for longevity, but we're happy. Engineer, Sean Wang, communicated everything quite clear and we understood what was going on. We needed more posts an the center beam of our house jacked up due to sagging. The three workers who came out, Mike Baines, Bryan Covell, and Brandon Pritt were all great. Very respectful of our property, really tried to keep everything neat and tidy. Answered all our questions along the way. Good job cleaning up. I love that they brought their own buckets (step up from other companies.) Again, all three installers of our new support posts were great and very polite. They did a great job from what we can tell.

Austin was incredible! Professional and courteous, knows his stuff and was able to answer all of my questions thoroughly. The thing I appreciate the MOST: he was NOT a pushy sales person – when we are ready to get the basement crack done, he’s my first call!
