"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"

"We are first time home owners with no clue about anything to do with home repairs. When we had a flooded basement we panicked and called several companies. While other companies used all kinds of tricks to scare us, give us high estimates and then a discount etc., we had the best experience with JES Basement systems. The sales associate Rich Thomas was a really nice guy who explained to us all our options without using any kind of pressure tactics. We signed a contract and later had to cancel it due to personal reasons. Even after that the office staff Susan Harris was really pleasant and agreed to refund our deposit without any hassle. It was definitely a refreshing experience to deal with such pleasant and helpful staff through out the company which is a rare thing these days when most companies are out to just get your money. This is definitely an indication of the good character and integrity of the company, its owner, and its staff. I would recommend this company to anyone who ever needs to deal with wet basement or foundation issues."
