NV Waterproofing was thorough and did a great job—just wonderful. They did a fabulous job. They fixed a crack in our retaining wall and waterproofed it. A's across the board.
I liked their response and good timing from the estimate to the guy who did the work. They were very attentive, and they did a good job. It was foundation repair. There was a crack in the foundation, and they took care of it. I've give them an A.
They knew what they were doing, and their workers were careful. They fixed a crack in the wall, and they dug a French drain. They did excellent work.
They did foundation repair. They were very responsive, and the results have been good. I haven't had any issues—A.
They did a good job. The repair is very good. They're excellent.
They did foundation repair for me. We had a leak in the basement that another company had attempted to repair and fill in, but a year later we had wet drywall again. NV Waterproofing came in. It's been almost a year and a half, or two years, and there have been a ton of storms without a leak. It's been great. I'd give them an A overall.
They were really good. I'd used them before, and that's why I used them again. They were good. I had a major leak in the basement. They also did some foundation work.
They did work related to waterproofing a foundation. I'd give them an A.
I liked their timeliness for the appointments, the quality of the work done, and the professionalism while on-site. They did both foundation repair and waterproofing for a crack in the foundation that was leaking water. I'd give them an A.
It seemed like they communicated well amongst themselves and through the leadership chain. There were two foundation cracks. I explained to them where I thought one of them was when they did the initial digging, and they listened to me very carefully. Sure enough, they went ahead and dug a little bit further to the side and found the actual problem. They had no problems doing that. They had good customer service. Their folks were very friendly and professional. I'd give them an A overall.
