“I liked that the guy that came out and did the repair on my wall is a good guy and did a good job. The wall was included with some foundation repair. They get an A, and I’d recommend them to friends.”

“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 told me what the problem was, what it was going to cost to fix it, and delivered the solution in the time that they promised it. They did foundation repair and waterproofing for me. They get an A. I would highly recommend them to a friend.”

“I wasn’t there when they did service. They dealt more so with my realtor, but she reported back that everything went smoothly. There was—the work was done correctly. They were doing foundational repair. I would definitely recommend NV Waterproofing.”

“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 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 very good. They were fixing a crack. They did very well, so I'd give them an A overall. They're great. I would recommend them.”

“They did a little bit of both waterproofing and foundation repair. I'd give them an A overall. There's always room for improvement. I would recommend them.”

“There was a crack in the foundation of our basement, and they sealed it. They’re A-grade.”

Review by

“They did a thorough assessment of my home, and I think they made a practical recommendation for the issue I had and resolved that issue. I was pleased with them. They repaired minor cracks in the cement wall by forcing a sealant into them and sealed them shut. I’d give them an A+. I would highly recommend them.”

“Since the first one—I've worked with them since. I don't know if the guy that—they just brought him and dropped him off and nobody came back to check on him until he was finished. I don't know if he was new or what, but he was the only one there. I guess he did a good job. Everything's covered. I just had a feeling that he wasn't the technician who had a little bit of direction. In the beginning they said it would take him a longer time, and he was finished fairly early. We had some cracks in our foundation. I mean, they weren't big cracks, they were just little cracks coming down. It wasn't through the pillar bar. It was just around, following the cinder-block down. I am satisfied with them. I'd give them a B- overall. I just don't know if the guy that came down—I said ‘aAre you going to do that?’ And they didn’t cover anything. And when they left I went down and the grit was still—it was on the shelf next to it. Maybe I should go down a little bit because they didn't clean up where he sanded off. I had to take a vacuum and go around and take stuff off my shelves and take it off. As far as that goes, that was not very satisfactory. I didn't call them and say anything, I just did it. When I talked the guy at first, he said they would cover everything, and there wasn’t anything covered. The first guy we talked to was very good. They were very nice and very polite and all that.”

“They seemed to do a good job. They seemed to come out quickly. The guy who came had cracks in my parents' basement walls and was trying to repair the house for sale. The water leaking didn't stop. That's not necessarily their fault because the recommendation was to dig a trench, but I wasn't going to do that before we sold the house. I can't really speak to their expertise, but neither did I follow their advice. The guy who came out was very nice and very helpful. He did the estimate, and the guy who did the repair work, we talked a couple times on the phone, so they were good with communication. The lady in the office did a good job scheduling and taking payments over the phone. The area had been leaking for a very long time, and when I went to go sell it, I had to do mold remediation. When the mold company pulled up the wallboard and insulation, there were clearly a couple of cracks in the foundation, so I called the NV Waterproofing to come fill the cracks, hoping that would solve the problem. Their assessment of the situation was expensive, but what they really said needed to be done was trenching and sump pumps, and that was not in the cards because I was selling the house. They responded to all my calls, did what I asked them to do, and did it pretty quickly. I have no reason to give them anything besides an A.”

“They did a great job. I thought they were very clear in what they were going to do. They told me the options. They went for the less expensive option, which impressed me. They did everything they said they were going to do in the time they were going to do it, and they couldn't have been nicer. They did both foundation repair and waterproofing. It was a cracked foundation, so they used epoxy to fix the crack and stop the water from coming in. I'd give them an A. They were excellent across the board. Another thing I liked is they didn't dig up my front lawn. I felt they gave me a fair recommendation and good pricing, and I thought they were good people. They were prompt.”

“They were thorough and did a great job. They were just wonderful. I have absolutely no complaints whatsoever. They did a fabulous job. They fixed a crack in our retaining wall and waterproofed it. They're an A. We weren't there when the folks came out to do the work, but they did the job when they said they would. I'm giving them A's across the board.  ”

“I thought they knew what they were doing. Their workers were careful in what they did. They cleaned up after themselves. They did a few extra things that I asked, so I thought they did a good job. They fixed a crack in the wall and they dug a French drain. They did excellent work. The reason I hired them is their technician was the only guy who could figure out it was a crack in the wall. Everybody else wanted to install a whole new drain system for me, but he seemed to be the only honest guy of the bunch.  ”

Review by
08/16/2016

“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.”

“NV Waterproofing just finished up with the railing and everything. They did a good job, and thank goodness they did a good job because the house is still standing. The foundation repair they did is very good. They're excellent.  ”

“I liked their response and good timing. From the estimate, to the guy who did the work, they were very attentive and did a good job repairing our foundation. There was a crack in the foundation and they took care of it. 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.”

“My basement flooded and they jackhammered around the perimeter of the basement and installed drains and two sump pumps. They had good customer service and follow-through. I'd give them an A.”

“NV Waterproofing did foundation repair. They were very responsive, and the results have been good. I haven't had any issues since they came. It's been a while, but I would give them an A. I don't have any complaints.  ”

“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 did a great job. They did a foundation repair. There was a crack and they sealed it up. They were punctual. They didn't mess around or play around with numbers. They told me exactly what it would cost. There wasn't a lot of hemming and hawing and trying to jack the price up. They told me what it was, and that's what it cost. I'd give them an A.”

Review by

“I spent $10,000 with them, still had a problem, and it took me 3 weeks to get a receipt from them for what I had spent. I then had to spend another $4,000 to repair the job. It should have been foundation repair, but they decided to go ahead and do waterproofing. In the process I subsequently learned there were actually foundational issues they could not have helped but see but did not tell me about. That's how I came to have to spend an additional $4,000. Their customer service sucks. They wouldn't even answer phone calls. I happened not to be here when they left, and the job was obviously not done. My husband paid them, asked for a receipt, and they said 'This check is your receipt.' I don't go that way. So I called and asked them for a receipt. They said, 'We don't do that.' It took me a month, many phone calls and emails, just to get a receipt, and it wasn't until it rained hard that I realized they hadn't done the job. They didn't do the job. One, they used bad judgment. They used poor technique. They used inferior materials. They should never have done it. It was obvious to me later but to them immediately that it was a foundation issue and they should never have done the job. Their punctuality didn't go so well either. They were late. Then they didn't come on the day they were going to follow up. Imagine the nightmare scenario and you've probably got it. Don't use them.”

“They overcharged grossly and in the end. It was outrageous, and they didn't give us a detailed invoice either. They didn't give us any of the information that we were supposed to have received from them in order to show the next people what they did. It was just a listing but it was no—apparently they did this work underneath our house. It was a sinkhole so it was an emergency and we needed someone right away so that's how we ended up with them. So he came and did this emergency work and after doing all the structural work you're supposed to give a blueprint, a diagram of what was done. Then there was another piece of work in the house that needed to be done and that's where they completely overcharged us. They also didn't lay out what they were going to do. They were really pushy when we said we need to think about this and they kept pushing but they never gave any detail on what they were doing or how they were doing it or why they were going to tear down a whole stone facade because there was a hole in one very large stone facade.”

“They seemed to know what they were doing, we had a crack in the wall they came in and evaluated everything and found the crack that had to be repaired and the guy come and do the work. I chose them because our neighbor used them. Yes there was a crack in the basement wall. What is this a survey for NV Waterproofing? OK I see, I would have to say an A. They definitely knew what they were doing and they explained what they were doing and how they were going to fix this crack, it was very informative. They answered our questions they weren't adverse to us looking at what he was doing and all that stuff. He made recommendations for the other cracks that were on the basement floor it was a good experience.”

“I don't have anything particular to say except to say that the work was done and so far it's held up. They sealed the crack in the basement foundation. I would grade them a B+.”

Review by

“I believe they might have fixed a crack. It was a small crack and they fixed it. They did what they were suppose to and it hasn't leaked since. The crack was in the basement. I would grade them an A.”

“the guy came in did his job very quickly, I believe that day I had to work, very professional. He was very friendly showed me what he was doing it was a positive experience. What he did was some polyurethane injections in my foundation. I would grade them an A.”

“They did the work that we agreed upon and did it well and did it in a timely fashion. They built a new half wall in our sub basement and put a drain in and a new sump pump. I believe it was a referral from my brother, and I would refer them to family and friends. I would grade them an A.”

“It was the sealing of a crack in the foundation wall. I would use the company again. My communication with the technicians who came out was great. I would give them a B. I would recommend the company.”

“NV Waterproofing were able to help me with my project last year. It was an average experience. They had to dig down to the foundation and to the wall. The work they did solved the problem we were having. I would give them around a 5 because one of the things I wanted a different way and they didn't do it. I wouldn't give them an A but probably a B.”

Review by

“They were very, very good. The experience was positive, and I liked the follow-up—there were no problems. I had a trench dug after a small flood. The water still comes, but not as much—I guess there’s an issue with the foundation underneath, which is beyond their control. I would give them an A+.”

“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+.”

“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 the work quickly, and we haven’t had any trouble. There was a crack in the foundation that needed to be fixed. Other companies wanted to dig up our yard and do a lot of other work, but NV Waterproofing fixed what we needed fixed. They patched the crack and fixed the leak. I’d give them an A.”

“NV Waterproofing did great work. They were open and honest, and the work was done quickly and very well. We had a crack in the foundation of the basement, and they sealed it. We were very pleased. The work is still holding up well, and there have been no problems with the rain—no leakage. I’d give them an A.”

“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+.”

“The work was good. They filled a crack in the foundation. A friend told me about them. I would go back to them again. So far, so good—there's not a leak. They came when they said they were going to come. I would give them an A+. They were good, and the guy was friendly.”

Review by

“They did some waterproofing where we had a leak in the house. It was a foundation leak. We have referred them to friends who have used them also. The price was right, and the work was very good. We've had no leaks since that time. They have good customer support. We would give them an A+.”

“NV Waterproofing waterproofed my house in the spring. They did an excellent job, and I’m very happy with the work they did. I had a vertical crack in my basement foundation. They sealed it from the outside with a three-layer membrane, and they did a neat job. Everything has worked out well—A+.”

Review by
10/17/2013

“We had three or four vertical cracks in the basement foundation, and they came and waterproofed. Fairfax County has a publication that publishes contractors and various other agencies—I'm pretty sure it was a white book with blue letters, and that’s where we found them. The customer service and the workers were very good. They were professional. They did a good job for a reasonable price. Most importantly, it worked with all the flooding that we had in the basement; it stopped it. I would give them an A+. They did a good job.”

Review by

“They sealed a crack in the foundation. The work seems to be holding up fine today. I liked the customer service, and the workers did a great job. They did a great job all around. I would give them an A+.”

“NV Waterproofing is a good group. They repaired a crack in the foundation of our house, caused by an earthquake. The guy who assessed the problem was very professional and knowledgeable. He answered all my questions. I’d give them an A.”

Review by
10/17/2013

“NV Waterproofing did a good job. We haven't any problems since. We got three different quotes—not just quotes but ideas about how to fix the problem; theirs just seemed like the most reasonable. It was probably middle-of-the-road as far as expense. One of the other companies wanted to do something very drastic, and the other company had something on the other end of the spectrum. I think that's why my husband ended up picking NV Waterproofing. They just basically patched a crack we had in our foundation. They pretty much came here and gave us an estimate, and we haven't had any issues with it since. We'll give them an A+.”

Review by

“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+.”

“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.”

“I had a back yard drainage problem where water was coming in from the foundation of the house. I got three quotes, they were all very similar estimates on the work. NV Waterproofing was the cheapest of three and seemed to have as solid a plan as the other two and so I went with them and it was good experience. It was a 2 day project. The labors were early. They were sitting out in my driveway 15 minutes before they said they would be here. They went straight to work, went through the entire day and finished on day 2 and put the lawn back in order. I would give them an A-. They could've filled in some of the trenching a little bit more and tamped down some of the dirt a little bit more. They need just a little bit more neatness in the finish.”
