    Mauricio explained 3 options that would fix the water problem we were having in our basement. He gave me details about the materials and process NV watering proofing would be using in my home. He never tried to sale me something I didn’t really need. Rich arrived on time. He walked me through what he was doing. He put everything back so well, you can’t tell any work was done on that wall. I would definitely recommend this company and their crews!

    Brian Flores, the service technician, was very friendly and professional. He cleaned out out the sump well in the basement and the sump pump itself. He had no problem with me watching the process to better understand how the unit operates. He kept the service area very clean. He deserves the 5 Star rating.

    Following up on our phone call I just wanted to say again how amazing Glen is and how pleased we are with the waterproofing work that you do for us here at Afnan & Co.! If everyone who worked on our job took as much pride and did work the way that Glen does it, then we would be the better for it! We love having you and the entire NVWaterproofing team work on our homes and we look forward to continued success with you all!

    The workmen showed up right on time. They were courteous and pleasant – and they told us EXACTLY what they were going to do. Once they dug down to the sewer pipe, Jim was proven correct as the pipe was broken completely in half. Originally, Jim thought the job would take 2-3 days. It was finished in one day – way beyond my expectations. This experience is one of the most satisfying I’ve ever had while having work done on my house. I can’t thank you enough for the courtesy, speed and quality your company provided. The team was fast and accurate. I am forever a customer, and if anyone asks, I will recommend your company as being the best in the business. The experience has been phenomenal, from the first day that Jim showed up to give the estimate right through having all the work done. Kudos to everyone in your company for doing a great job.

    The reason for this high review is because of the high quality character of Jim. NV came to my home to investigate water infiltrating my basement from a front foundation wall. Jim assessed the problem as best he could, but because I had left the dry wall up he was unable to immediately access the area inside the drywall. Being at work at the time, I asked my wife to cut back some of the drywall to take a better look. Jim stayed and not only helped my wife cut away the drywall and remove sopping wet insulation, but helped her find that the problem had originated with a leaking pipe in the wall that we did not know was there. Although the company policy against removing the drywall themselves seemed odd to me, nevertheless it was their policy. Jim went above and beyond to help my wife remove the drywall and insulation, which with two small kids was going to be very difficult for her to do by herself. He helped clean up and was polite and respectful. While I am grateful I do not have a foundation leak, should I ever have one, I will call NV Waterproofing and ask for Jim. Quality people are hard to find, thanks man.

    We used NV Waterproofing (NV) to fix a basement water leak in an addition to our house. NV provided the clearest estimate (we received estimates from multiple companies), with clear pricing and identification of issues. NV completed the work promptly. While the initial work did fix the primary problem, we had a small leak remain. NV was great about coming back out to figure the issue out, and found a surprising construction anomaly causing the second small leak. NV fixed the problem (all as part of the initial estimate) and our basement has been dry since. We were very pleased with NV's persistence and ultimate solution to our problems. We strongly recommend NV.

    We have used NV Waterproofing several times now for different issues that have arisen in our basement. We have found them to be very professional, courteous, and knowledgeable. Unlike many other waterproofing companies which try to sell you very expensive one-size-fits-all whole-house solutions (which are a rip-off with no guarantees), NV Waterproofing takes the time to target your specific problem and provides the most economical and effective approach to the problem. We appreciated their honesty and creativity in designing a plan for our flooding issues. So far, all of their work has held up great! I would highly recommend them.

    I wanted to take a moment to thank you and NV Waterproofing for a job well done. From your visit to our home, to the reasonable estimate, to my communications with Jayne, working with NV Waterproofing has been an excellent experience. The work crew showed up on time, finished in one day and left the basement very clean. My wife commented on how friendly the crew was, and they answered all of her questions. We look forward to rainy days now, without the fear of our basement leaking. Thanks again to all!

    Your crew worked hard all day, only taking a short time for a quick lunch. The men were neat, completely covering all areas that they used to remove concrete, dirt and debris. They were on task the entire time. We were very impressed. We have had a lot of work completed in our home over the last 38 years, and I am pleased to say that your employees are the most conscientious we have ever worked with.

    Oswaldo did a great job in walking us through the steps . He was very experienced and clear about the job. The crew started on time , completed much earlier than I had thought ( less than 1 day) and left the space very clean. Oswaldo was good to talk to and answered all out questions. Great work. Thank you Oswaldo. Brian Bui Brian was very good . He was so focused in really trying to understand our problem and providing us a solution . He did not seem to be busy trying to sell products but instead paid all attention to solving our issue . Very customer focused . He always responded to our questions and calls . He even came to check how the job was going on the day of work. Very much appreciated. Thank you Brian. Keep up the good work!!
