There was a small crack in the basement. NV Waterproofing fixed it, and it hasn't leaked since. They get an A grade from me.
We had a crack in the basement wall, and they evaluated everything, found the crack, and did the work. They earned an A. They definitely knew what they were doing, and they explained how they were going to fix it and answered our questions. It was a very informative, good experience.
The guy from NV Waterproofing did his job very quickly, and he was very professional and very friendly. He also showed me what he was doing; he put some polyurethane injections in my foundation. I'd rate them as an A.
I think NV Waterproofing did a good job. They fixed a crack in the basement. They did the job very well; I had no complaints whatsoever. I would give them an A.
They were prompt, initially, and they resolved the issue with me in the end—that was really good. The pipe needed to be extended further away from the wall. This was my first time using the service. They were able to do everything in a timely way, and the cleanup was great. I would rate them as an A.
NV Waterproofing did a big job for us. They fixed a buckled basement wall, and they installed a French drain, took the wall down to the foundation, and rebuilt the wall. The work has been terrific so far. It has stayed dry—no problems. I would hire them again, absolutely. The customer service was very good. I would give them an A rating.
NV Waterproofing did a very good job, and I was satisfied with what they did. They did what they said they were going to do, they were very professional, they showed up on time, and they did the job straight through. I was pleased with their work—I would give them an A+ rating.
We had the house on the market, and the inspector found a foundation crack. NV Waterproofing went in and fixed it. We were super happy. They're an A+.
The guy from NV Waterproofing that did the work was probably one of the best contractors that there has ever been. He had to dig the dirt around the foundation, and he was such a hard worker—he really was. I would recommend them to friends and neighbors. That company was really wonderful. I would give them an A+. I think there were actually three different companies in the Best Pick Reports, and I chose NV Waterproofing from there. I had called up two of them, but I think NV responded first, and I think they had a lot of customer referrals that were really happy with their work. I was so happy with NV Waterproofing.
It looks good. I went and checked the other day, and it's holding very well. They did crack sealing in the foundation. I heard about them through the Best Picks magazine we get. The customer service was good. I called, and they were responsive. They came out, checked my stuff, fixed it, and left. They're an A+.
