“I thought NV Waterproofing was great. The salesperson was very thorough, gave me all the information I could have ever wanted, and then the person who came to do the work was so enthusiastic. He loves what he does.”
“NV Waterproofing put in a sump pump, and they lined all the walls, and they did what they needed to do to waterproof our basement. We haven’t had any problems. We were very happy with what we had done.”
“They repaired a fissure in my foundation and put in a little bit of a retaining barrier, as well as a conduit, to move water away from where the fissure occurred. I feel it was very good-quality work. There haven’t been any problems since. If I had a friend that needed a referral, I wouldn’t hesitate.”
“They did a marvelous job. I am 100 percent satisfied. This was probably two and a half years ago. There was standing water in the basement. We have had some horrendous rain since then. A couple of hurricanes came through and dumped tons of water, and my basement has been dry.”
“They did a great job. I was having water coming through my townhome basement, and I guess its drainage system was eroded. They actually ran a new drainage system for me and put in a sump pump. I’ve had no issues whatsoever at that townhouse since they’ve done it. They did a great job.”
“They were very knowledgeable. I had a major wet basement problem, and there was some cracking in the foundation. So they did the excavation around the outside, dug up the old drainage system, and put in some new drainage. I would use them again in a heartbeat.”
"I had a sump pump installed by NV Waterproofing. They did a very good job, and I would refer them to my friends."
"The gentleman came out, and I thought he was great. The situation didn't really need remedying yet, but he gave me some good advice. I was very impressed that he didn't just try and sell me. He said, 'I don't really think you're there yet with the problem you have.' He was great. He thinks it can be a while before I have to do anything."
"It was outstanding; I already have recommended them. They just did the front, but they completed the job in a very timely fashion. They cleaned up wonderfully, and it was a very good experience."
"They did an entire basement with five sump pumps. They did a good job—no complaints. The workers were all neat, orderly, and hardworking."
"They did work for me. They put in a French drain for us. That worked out fine; I had no issues with the company."
"I use NV Waterproofing. They did a really good job of the foundation repair. The quality of the work was fantastic, and I haven't had a problem with it. The technicians that came out were knowledgeable, friendly, and hardworking. They cleaned up after themselves and didn't leave a mess. I absolutely would recommend them to others."
"They actually did a small job of installing a drain outside of the house. The crew was easy to work with. I had no issues with customer service; they were wonderful. I would use them again or recommend them to someone else."
"I would say it was a small job. They buried a drain line and connected our downspouts to it, to try and mitigate some leaking we had in the basement. I believe they were thorough with their work; I was satisfied with their services."
"They did a good job. Everything went pretty smoothly, so if I needed to, I would use them again."
"I remember having NV Waterproofing out for service. They were pretty responsive, and they did well. I had a crack in my basement wall, and some water was seeping, so I called them in to seal that crack. Then after we had the little earthquake, I think some of the crack was opened back up, so since it was under warranty, they came back and fixed it again. I would say they do quality work. I thought they did well."
