HOMEOWNER REVIEWS SELECTED FROM SURVEYS COLLECTED:

“I liked the gentleman that came out to oversee the work and followed through with the work from start to finish. He was available for any questions, was able to answer every questions that I had. I believe he was honest, truthful and integrity—just a wonderful guy. His workers that came out, he got them started, they worked diligently, very good, very clean, very clean effort, just a wonderful job. They did a waterproofing job for me. As far as customer service, the folks that I spoke to at their office, they were very, very helpful, extremely polite from start to finish, they were excellent. They earned an A+. I would highly recommend them to a friend, and I already have—they are wonderful.”

“I was real satisfied with these people. They did an excellent job. I think they did everything—I'm a general contractor, so I'm familiar with these things, and they did an excellent job on everything. They did waterproofing for me. I would give them an A+ overall. I'd recommend them very highly.”

“I've used them a few other times. They've done a lot of the work for the rental property we have. Working great, so far, so good. They did waterproofing jobs for the rental property. I give them an A+. I would highly recommend them.”

“NV Waterproofing did great work. They cleaned up well. They told us everything that needed to be done. They're very reliable. There was a leak in the foundation, and they did some other things. I'd rate them A+. They really were great.”

“I liked that they started on time, finished on time, and they did what they said they were going to do. They dug a trench and put some drainage pipes in. They get an A+.”

“It was great. They were really responsive, and their crew leader was really, really helpful. I had probably a thousand questions while they were working, and he was quick to answer them and gave good information and never seemed frustrated or anything that I was asking a thousand questions a day. They were quick and did a really good job. It was waterproofing, but they had to excavate our basement to do it. I'd give them an A+ overall.”

“NV Waterproofing took the time to make sure they did it right. They were attentive and told me all my options and let me pick. I had a leak in my basement. I would absolutely give them an A+ overall. I was very happy with them. Their customer service was great. I would absolutely recommend them. They did great work. I had four people out, they were great.”

“They did good work. They did a waterproofing job for me. They did A+ work.”

“They did waterproofing for us. They're A+.”

“They took care of what I needed. They did waterproofing. They installed a waterproofing membrane. I'd rate them A+. I would highly recommend them. I would use them again.”

“They've always given us great service. They've done waterproofing for us. I'd give them an A+ overall.”

“I liked that NV Waterproofing got the work done faster than initially estimated. They did waterproofing, interior drain tile for me. I'd grade them A. I would highly recommend them.”

“I liked that they came in when they said they were going to come, did what they said they were going to do, and cleaned up. They did waterproofing, put in tile. They did A work.”

“They were great. I liked that they have good service, did the job quickly, great, and it worked pretty well for us, very positive. They installed a water evacuation system for me. They get an A.”

“My husband seems quite satisfied. They put in a pump—I don't know exactly what they did, but it kept our basement from water. They did some outside work, as well as fixing in the inside. They're A+. We haven't had any problems since. I would very likely recommend them.”

“They sealed up the cracks in our basement. It was sorely needed. They came out, they looked at everything we identified, and identified a little bit more. The guy told us everything he was going to do. He went along and got the job done. Overall it was an A+ job. I would recommend them.”

“They were here, and they were good. They're very hardworking. They seem to really know what they're doing. They did waterproofing for me. I'd rate them A+ overall. I have no complaints. Some associate of my husband at work recommended them to us. We used them, and the basement is so much nicer now. Every time we get rain we don't have to worry about it any more. It's so nice.”

“Very meticulous work. It was just waterproofing—we had a crack in the wall. I'd rate them A+.”

“I guess I liked that they were responsive, communicative. They did waterproofing. They filled in some cracks so water couldn't get in. I'd grade them A.”

“They were on time. They did what they said they were going to do. They did waterproofing. Maybe it would go under foundation repair because they did seal some cracks. But they did a couple of things. They sealed some cracks in the foundation, but they also dug trenches and put down pipelines to divert water from the drainage spout away from the house. So it was two different things they did. I would give them an A overall. It's not leaking.”

“I liked that they seemed to know what they were doing, and they did it relatively quickly and efficiently, and so far, it seems to be working. They put in a sump pump for me. Overall I'd grade them A.”

“I liked the—when they first come in, they tell you where they think the water's coming in from. They completed the work, but then the next day rain and water had come in, so they came back and redid another area they saw the water coming in from. They put in the little footer. They dug up the hole and everything and put in a new sump pump and put a footer around the wall. The only thing they don't do is repairs to the wall. I would rate them A overall. I didn't have to do too much. Once he came out, then that was the only person I had to talk to. They cleaned up all their mess. I think I've already recommended them.”

“They were good, did a good job, and cleaned up everything real nicely. They did a waterproofing job for me. I'd rate them A. I would recommend them.”

“They did what they said they would do, and really I'm just very satisfied with their work. They did what they said they were going to do, which nowadays, I guess that's unique. They're very easy to work with. The crew lead was really good to work with. I'm very satisfied with the work. What they did was they put an internal French drain in and they put something else in. I'd give them an A overall.”

“They were fast and comprehensive. They did water mitigation. They did a lot of gutter work and a few other things. I'd give them an A-.”

“They've been great. I liked that the representative that came was knowledgeable about my situation. I didn't have to spend money where I didn't need to spend money. I felt very good, they explained the situation. I had them out several years ago when we had ten inches of rain, and I had a little wetness in the corner, and at the time they repaired it, and I never had it again. I had another area that needed to be fixed, and they fixed it. They did waterproofing work for me. They're A+. I would highly recommend them to a friend.”

“NV Waterproofing did the waterproofing for the basement, ran a drain out to a ditch, and did a sump pump installation. We had a couple of friends who'd used them, and they said they did good work.

“They put in a sump pump for us, and they did a good job. They finished the same day. I'll give them an A.”

“They did very good work. They did waterproofing. All the people involved were professional and courteous, and they responded pretty quickly.

“I had such a positive experience.”

“I'd say they're an A.”

“NV Waterproofing made it a completely positive experience. I'd give them an A rating.”

“It was well done, it was quick, and it's been looking great. They installed a sump pump for us. I'd give them an A overall.”

“They were responsive. They were professional. They were very thorough in terms of explaining everything. We even had a small issue with the measurement of one of the pipes—one guy told me one thing, and another guy told me something else—but they totally rectified it by giving us a credit and not charging us for the additional footage. They were good. It was a positive experience. We haven't had any water issues since. They installed our sump pump and did some outside drainage stuff for us. I'll give them an A.”

“They had good communication and expert opinions on what needed to take place to install a French drain in the basement. I'd give them an A.”

“NV Waterproofing did two French drains for me. I'd give them an A.”

“Everything was great, and they did a good job. It was waterproofing. They fixed the problem. I would say that they get an A grade.”

“They arrived when they said they would, and they got the job done in the time frame that they specified. They were polite and professional, and so far, it looks like what they did is working. They offer a 20-year warranty as part of their work, so I'm completely satisfied. They excavated about 34 feet of the exterior of the house, tarred it, put a water retardant material over that, and did the piping to collect water down at the bottom of it. They filled it in and put in a sump pump. They did it in five days, just as they said they would. I was totally satisfied based on what I now know, and I would grade them as an A.”

“NV Waterproofing did an excellent job. I was happy with their service, and I would use them again. They were very professional. We had a leak in the basement bedroom, and the water was coming through the basement wall. They get an A+ grade.”

“We're in pretty good shape. We recently had waterproofing from NV Waterproofing about a year ago, and it's held up pretty well. They were able to help us. We had a number of cracks in the basement that they were able to seal, and the water has since stayed out. It's holding up very well, and it's in good shape. The technician knew what he was doing, and they made very little mess. I would give them an A+.”

“I was very happy with them and very satisfied with their professionalism. The workers were very, very professional, timely, and communicative. I would use them again, if the need presents itself. They waterproofed part of the outside of the home. It took several days, and I was satisfied with their work. I would rate them as an A+.”

“It was, overall, a very good experience. They did a good job fixing the problem. There were no issues. There was water in the basement—it was coming from the outside into the home. The service they provided prevents the problem from occurring again, so I would give them an A+.”

“They were prompt and on time. The most important thing is their system actually worked. My basement water problem is no longer an issue. It all worked, and they did the work proudly. If there were any issues, they fixed them right away. They did the inside for me—they did a sump pump. They're an A+.”

“It was quick and pleasant. They waterproofed my basement. Water was coming from the outside, and everything is OK now. I would rate them as an A.”

“They did a good job, and it was a very positive experience. They were very prompt—as soon as we called them, they sent somebody. The gentleman was very good. He came in, and he did a good job. We had concrete in our basement, and there was a crack. Then he came in and fixed it very nicely, and afterward, we had no further leaks of water. I would rate them as an A+.”

“From the estimator to the finished job, they were a nine out of ten. They did a really hard job by chopping all the concrete out of the basement around the walls. They dug a ditch 12 to 18 inches from the wall, put in a plastic pipe, put in gravel, added cement to it, and cleaned it up. They also did sump pump work. They're an A+.”

“Their service worked. I had a crack in the basement wall that needed to be filled—it occasionally leaked. The services did work, and I would give them an A.”

“I liked their flexibility and promptness when resolving the issue. I have had several companies come in and give me estimates—it was like, 'We have to do this, and we have to do that,' and it was this huge fee. With NV Waterproofing, I remember them saying, 'We can do this, and we can do that. Do this, is what we recommend—it's a little cheaper. We would go with that, and we can do this later.' I thought they were very honest in their assessments and recommendations, so I felt more comfortable with them. I had a crack on my basement wall, and everything has turned out to my expectations. I had no complaints and no issues whatsoever—A+.”

“NV Waterproofing did waterproofing work for my walk-up basement, where I had a drain issue. They did great work. What stood out about the company was the quality of their work—it was done on time, and they were very polite. It was good, so I would give them an A rating.”

“I was kind of working on this all by myself, and NV Waterproofing was very responsive to my many questions once they started. I actually had a distant family member kind of consult with them while they were on the job, because of a question I had, and they were very gracious about doing that. They were great. They did waterproofing work. Overall, it took probably a week to complete the entire job. I found them through Best Pick Reports. I felt as though the technicians had a good attitude, and their cleanup was very good. I'd give them an A.”

“NV Waterproofing fixed a leak in our basement, and that was my first time using them. I chose them after a recommendation from another contractor. When that work was completed, I did not have to go and clean up behind them. They did not have to come back out and touch anything up, that I recall. I'd give them an A.”

“NV Waterproofing did a very good job. They installed an outside sump pump. The quality of the work was very good, and so far, the work's very good. An A is the grade I'd give them, and I would use the company again.”

“I think I got exactly what I needed. I think they were very good in describing what the fix would be, and they did it. They put in two sump pumps. The cleanup was very good. This was the first time I used that service, and I would give them an A.”

“They did work for a drain and sump pump. It was a very positive experience, and I would recommend them without hesitation.”

“What they did worked. They did waterproofing in my basement's interior. They were able to do it in a timely fashion. I would give them an A.”

“NV Waterproofing did an excellent job. They did waterproofing on one end of my house, and they did an absolutely wonderful job. They did the job the way I felt it should be done, and when they left, everything looked perfect. They're an A+, no doubt.”

“NV Waterproofing was very cooperative, and they did a great job. They waterproofed my basement in two different places. The first job was inside; the second job was outside. Everything worked when they were done, and they cleaned up after themselves. Their initial contact was wonderful; the crew was good—no complaints about them whatsoever—A+.”

“NV Waterproofing was great; they were on time; and everything was clean and, I would say, perfect. They installed a French drain and a sump pump. They were able to do everything in a positive fashion. I would grade them an A+.”

“They did waterproofing work for me in March. It was awesome work. They put in a sump pump system. I would recommend them 100 percent. Everyone that I dealt with—from the sales consultant to the workers as well as the office staff—was extremely patient and extremely accommodating. I would give them an A+.”

“I had a water leak, and they fixed it. I heard about them through friends of mine. I was very happy with NV. They were very professional. They knew their business and were willing to help. They got here in a timely manner, and they did an excellent job. I would give them an A+.”

“It was great. They were quick, they stuck with the estimate, and the guy was here for less than hour. I had a leak in the basement where water was seeping in from the outside, and they stopped up the leak. It was waterproofing with some kind of weird epoxy stuff. I don't know the mechanics; I just know that it works. It's been perfect ever since. I would recommend them. They definitely get an A.”

“They dried out our crawlspace and put in a sump pump. It was waterproofing work. Someone referred me to them. I felt the guy who came out, Jim McCabe, seemed like a very trustworthy person who seemed extremely knowledgeable about this sort of a process. He seemed very honest, too. I'd give them a solid A.”

“They installed a waterproofing system in the house. I heard about them from my daughter. I was very pleased with the service. I thought the customer service and workers were excellent. They were absolutely polite and respectful. I would give them an A.”

“NV Waterproofing was clean and neat. They were concise and precise about how they did it. It took the guy like three hours just to make the plan. They were measuring everything from this way to China. It was just an expert job. I have no water in my basement. I give NV Waterproofing an A+ grade.”

“I thought they did a very good job. They responded very quickly, scheduled the work, and showed up. They did it really well, I thought. They did some interior waterproofing on the foundation. I'd give them an A+.”

“My husband is the one who takes care of the house, so I don't really know all the details. I think they installed a sump pump. They might have been in some booklet that we got in the mail that was like DC's Best Picks for home repairs. My husband dealt with the customer service and workers. The work is holding up fine, and we haven't had any trouble. I would give them an A+.”

“NV Waterproofing did waterproofing for us last year, and we were very happy with them. It's held up just fine so far. We didn't have any communication problems with the company. The workers were very polite and helpful. I would give NV Waterproofing an A grade.”

“They did some flashing and waterproofing. The workers were great. They were definitely an A. As far as I know, the work has held up fine since it was done.”

“The work is fine. They did a great job. I used them years ago. Someone recommended them to me. They persisted until they solved the problem, and they were very good about coming back. They did waterproofing work for me, and it's still holding up well today. I would give them an A.”

“They did waterproofing. The work is holding up fine. We haven't had any problems. I would give them an A.”

“They waterproofed my basement. We moved out of the house, but while we were there it was fine. They did a nice job. I would give them an A.”

“NV Waterproofing did what they were supposed to do. Everything was according to the contract. They started and finished it on time. We haven't had a rain yet, but so far, it holds up. I would give NV Waterproofing an A grade.”

“They did the tank. I thought it was great. It looks very solid. They did the footing as well as the stuff on the wall. I haven't had any problems since then. I thought they did a great job of it. I'd give them an A.”

“They fixed a minor crack in the wall. Everything was first-rate. The work seems to be holding up well. I would recommend them. I feel very comfortable recommending them to somebody else. In fact, they did good work, and they did everything they promised at the price they promised. I would give them a solid A.”

“They did an excellent job. I thought that they clearly had expertise; they knew what they were doing. They recommended a sensible solution to my problem that was not necessarily the most expensive solution. We had a couple of glitches, but they always made it right. They were very responsive, and they always showed up on time. They waterproofed my basement, did some exterior excavation, and then waterproofed the side of the house. I heard about them in some sort of booklet I got in the mail. It was a white book with blue letters. It was excellent. I would definitely recommend them. I'd give them an A.”
