My house underwent foundation repair. Everyone in the process was professional. I want to especially acknowledge the team who performed most of the work on a daily basis: Jose Lopez, Daniel Yacila, and Jesus Baires. These three gentlemen knew the work. They communicated the scope and promptly alerted me to issues. They left the work area in a clean and organized condition. Moises did a good job managing the crew. Grateful to work with these men.

JES Foundation Repair is best in customer service, knowledge – they know what they're doing and need to do and got the beam in my foundation replaced to my satisfaction with photos. Lee, the person I interacted with was excellent with service, inspection, quote and all around always called me back asap, worked on weekends, did everything he could to make this repair a 5 star experience. The crew, led by Seth, was polite, explained everything to me and got the job done. Highly recommend.

JES did wonderful work for our home. The team we had for the outside work was Agustin Morales, Eduardo Morales, and Jorge Duron. They were very professional in every aspect of the job. I was impressed how they took the time to lay plastic down in our flower beds to keep from disturbing the mulch. This seems small but means so much, especially since we just put it down recently. They let us know when they were arriving via text which was great. Agustin explained everything that was being done and did a walk around with us after the work was complete. He even took the excess dirt and filled some low lying areas in our back yard. We truly appreciate the professionalism and care you took of our home.

Extremely professional company. Followed through on every detail—told us when they would be here, what they were doing, and arrived on time.

We had our outside walkway lifted today as it had sunk to a dangerous angle. JES gave us a thorough inspect and estimate. They arrived early and did an excellent job being very respectful of the lawn and gardens. Bryan Rutherford and Austin Hicks were the technicians on the job. Very pleasant to deal with and explained everything. Thanks JES.

I moved into my home just over a year ago and have had three basement floodings. After trying to figure out the solution on my own, I gave JES a call. Best decision I ever made. The three young men who performed the basement waterproofing did an standing job for me. They were professional and courteous.

The entire JES team needs to be commended — Rafael Garcia, Jose Lovato, and Wilton Mendoza — the very fine crew — arrived on time and ready to do the work; they worked efficiently, effectively, and knowledgeably as a well-oiled team and "machine." They informed us of each step along the way and explained everything thoroughly and completely. They used pictures from their phones to help explain the process and what they were doing. After they finished their work, they cleaned up the work area, gave us all the written information we needed, explained everything — they were so informative, helpful, knowledgeable, kind, WARM and FRIENDLY! It's so nice to work with friendly, happy, smiling people! What an amazing staff — Ally at the office — thank you for answering our questions, being so efficient, providing assistance, and being so warm and friendly, too. The JES crew gave us the invaluable peace of mind that our basement will stay dry. No more worries about rain or mold or mildew or critters getting in! We give you 100 stars! All As, 100%! Thank you so very much!

This five star review is for Ethan Mooney, the JES repair person who recently helped us with our JES project. Over 6 months after having JES complete installing a liner, dehumidifier and pump under our family room addition, we still noticed water. The service repair person, Ethan Mooney, recently came and found that the pump was never plugged in! Ethan was professional and not only fixed that easy problem but installed new equipment and inspected the liner. He was wonderful.

Had JES come out and install a box drain. Darrell M. The job supervisor called me early that morning to let me know what time he was coming. He greeted me and introduced himself and his crew, Ricky J. And Allen B. He told me what he was going to do and asked if I was ok with what he was going to do. They got right to work. When they were finished, he knocked on the door and showed me what he'd done. The job was done beautifully, and the clean-up was too. I'm very pleased with the work. And would use them again

Joel from JES provided top-notch, speedy service to repair a broken pump in my basement and run a new pipe through a tight crawlspace and out of the side of the house. Was a really tricky job, but he got it done right and took the time to communicate with me what the plan was at every step of the process. Very professional approach and results.
