A selection of 286 homeowner reviews:
“The work was extremely fast, and it was neat. They put in a sump pump. They were excellent. They get an A.”
“They were very professional in everything they did. It was a very courteous and professional way they did it, and I was pleased. We've had a lot of water since then, and I haven't had any in my basement; that's the important piece. I'd give them the highest score—an A+. I had no complaints at all. Every aspect of the work was done well, and their people were great.”
“They were very good. AquaGuard waterproofed my basement from the inside. Everything was good. I would say they were excellent.”
“He was very thorough, very cordial, nice, and good to work with. I'd give them an A. I did not have any issues, and I would recommend them very highly.”
“Overall, it was OK and it seems to be working. I'd give them the highest rating, A+. I think they're fine.”
“I cannot remember the name of the company that I used. I would give them an A. Everything was perfect, smooth, zero problems.”
“They were very efficient in their work. They cleaned up after themselves and they were well mannered and polite. So overall it was a good experience if you're going to have to have some waterproofing and stuff done to your house. I would give them an A. I would recommend them very highly.”
“Everything stood out, from the job to the clean up—you name it. I had a big leak. I'd say they were a 9, excellent, no complaints.”
“They did a nice job. It hasn't leaked. That's the main thing, it hasn't leaked. They were installing a new drain system. I'd give them an A. They were excellent, they did a nice job.”
“It was very good, they did a very good job. I was very happy. They fixed it, there was water coming inside my house. It was good, excellent, no complaints. They did a great job, how they're supposed to do it. They did good.”
“What stood out was their level of personal care and interest in solving the problem. They were great. They repaired a leak. I'd give them an A+.”
“Competent in what they did, efficient, professional. It was a very good experience all around. They were putting in a sump pump system. I'd grade them an A.”
“They got there a little bit late in the morning for my taste, they didn't show up until around 9. But all their guys were very courteous and they cleaned up after themselves. They did a good job. They did a basement drainage system. I'd rate them an A.”
“They were on time and they did the work when it was supposed to be done. Everything was fine. They did basement waterproofing. I would say they are an A.”
“Nothing in particular stands out to me. They did some waterproofing in our basement. I'd give them an A.”
“They were neat and quick, and everything worked as they said it would. They put in a whole water maintenance system. They dug out my entire basement and put in two new sump pumps. So far, they're still getting an A.”
“They were fine. It was a good job. They were installing a drainage system, repairing a leak, and all that stuff. I'd rate them an A.”
“They did fine. They took care of some stuff that I would think wouldn't be part of their job, like they moved some stuff out the way for me and helped me out. They were installing a drainage system. I'd give them an A, no problem. They didn't really do anything bad. They knocked everything out, kept the area clean, and moved some items for me. They did well.”
“They were very responsive. The project was a while ago so I'm trying to remember. The quality of the work was very good and they were very expeditious as well. They put in a drainage ditch in our backyard to move water away from our house. I'd give them an A.”
“It's still holding strong. They seemed really honest, it appears that they did pretty good work, and they actually showed up on time. They installed a bilco door. I'd give them an A. I didn't have any issues.”
“I mean they took care of everything in a pretty efficient manner, with no issues really. They were doing the sump pump. I'd grade them an A.”
“Nothing really stood out to me. They were courteous and they were prompt in delivering the product and installing it. It was like a humidifier. I'd give them an A.”
“Nothing stood out about them. I had a sump pump placed. I'd give them an A. So far I haven't had any issues.”
“It was a very positive experience. They were very responsive and proactive. They did a good job. They were working on the basement. They had to replace a slab that had sunk in the back field of dirt that had washed away, lay down a new slab, put in kind of the French drain pipe around the perimeter, and a couple of septic sump pumps and some long pipes to take the water out to the backyard. I'd give them an A. They were good, they were pretty professional. It's very likely that I'll recommend them.”
“They were quick and got it done. They did what they said they would do in the amount and in the time they said they would do it. They were waterproofing the basement. I'd give them an A.”
“Their timeliness stood out. They were waterproofing my basement and putting in a French drain. I'd give them an A across the board.”
“They were very responsive and they made sure that they did the job right. They came back and fixed the little things that they didn't do right. They expanded the lane, poured concrete underneath the stairwell, and fixed the basement. I'd give them an A-.”
“They were clean and they did the work as requested. They were doing a sump pump. I'd rate them an A.”
“Basically, they're very customer-focused and knowledgeable. They were basically waterproofing and stretching some cracks in a foundation. I would give them an A.”
“He explained everything that he was doing. He was very clear, precise, and made it understandable what was going to happen. It only took him less than a couple hours to do the job. They were repairing gutters. I'd give them an A overall. I already have them going to my mother's house.”
“They did some work on my father's house that I sold. I would give them an A across the board. They did a great job. I have actually recommended them already.”
“The house is dry, we just put the floor back, and got the wall back. Everything's fine and we're very pleased with everything. They went in and dug out the basement wall, and put a French drain in and put a sump pump in and drainage out the back. So yeah, that worked quite well, and of course replaced the floor and did the concrete work. They did that quite well. I'd give them an A across the board. Everything went according to Hoyle, everything was done on time, we had no issues, and we still have no issues.”
“It was a very good job. They weren't repairing a leak. The job was well done. I'd give them an A.”
“It was fine, everything was great. I don't usually do surveys. It was very nice and I have no problem with it. I'd give them an A. I wasn't there the whole time. I know when I was there they were very nice. They did everything, the basement was cleaned up and everything else was cleaned up. I would recommend them.”
“They did a good job. They were professional, on time. They did exactly what they said they were going to do. They were reliable and they came back for a second visit because they needed to with no problem. I would give them an A.”
“Their work was very fast and it was very professional. They were installing a sump pump and some waterproofing stuff, I can't remember. I'd give them an A.”
“They did waterproofing. I'd give them an A, absolutely. They had to put in a box drain which really took some time and expertise so that the water draining into the stairwell next to the basement would not leak into the basement. They connected that to the sump pump and I was very happy with that.”
“The consultation seemed to go really well. There seemed to be a lot of positive information. I'm not a fan of upsell tactics. And then the actual installation, the actual work was on schedule. They took pretty good care to keep the area clean and protect the rest of my home that they weren't working in. I think I'd give them an A-, and that would only be because some of the items that they had to remove they did not replace. And when I asked about it, they said, 'Oh we don't replace that.' So it was kind of, they were almost there. They were doing waterproofing in my basement, so they had to patch my sink and they didn't put it back. So it's kind of like, 'You took it off the wall, how come you're not putting it back on the wall?' They were very punctual. They were very clean. I feel like I can't answer expertise. So far we haven't had any water, but the water was spotty prior to hiring them so I don't know. I didn't sit and watch them actually deal with the channels.”
“They did good waterproofing work. They did exactly what they said they would do, and it was on budget. The best part was probably the sales representative. Will was a pretty cool guy, and he was really good. I chose them because he was a solid dude who was pretty funny and a straight shooter. They get an A.”
“AquaGuard got the job done. I'd gotten a couple of quotes, and AquaGuard was recommended by a real estate agent that lives in our neighborhood. They did the waterproofing in my basement, which took maybe two and a half days. They were very friendly and really nice, and even when it was raining outside, they were hauling out the trenches they'd drilled in my basement. The guy who came for the estimate was very nice too. I don't have any issues at all, so I would give them an A rating. It's been over a year, and everything still seems to be working.”
“They did the work, and we haven't had any problems with the basement at all since. They showed up on time and had good customer service, so I would definitely give them an A rating. They did a very good job.”
“They were great. They did waterproofing for the basement. They were professional and did what they said they were going to do in a timely manner, and I haven't had any issues since, so it's all good. They're an A company.”
“We did use them, and everything turned out well. They came out and installed a new drainage system in our basement. The only problem that we had was some cracks in the floor when they redid the concrete, but they came out and patched that up. If we have any other problems, we can just let them know, and they'll come out to do a bigger repair. Their customer service is good, so they get an A from me.”
“If I had something I wanted to do that was just a little bit different from what they had previously planned, they had no problems with that. They accommodated my requests. I chose them because they seemed to be the most knowledgeable about the work, and they were clearly qualified to do the work. Some of the other companies I had quotes from seemed like they were not being entirely honest, but I felt like I could trust AquaGuard. They waterproofed my basement, which means they put in an interior drain around the perimeter of my basement and a sump well with sump pumps and back up pumps.”
“We'd had a leak in our basement, so they came to try and figure out if it was related to some work they'd done previously. We chose them because of that previous work.”
“They were good. The guys worked efficiently while they were on the job, and they seemed to have done a good job waterproofing. I was helping my brother at his house, but I think he's been satisfied, because he hasn't had any complaints. I thought their salesman was the most frank of all of the companies we looked at, and I appreciated the directness and the honesty of the presentation. I'd give them an A.”
“They were straightforward, trustworthy, and timely. They did waterproofing. They were our first call.”
“They seemed very straightforward. They did waterproofing. Customer service was good. I'd give them an A.”
“They did the job quickly and neatly, and they were friendly doing it. They were recommended by a friend, so we took them, and they were just nice to work with. They get an A.”
“They repaired our foundation in the spring. The guy that came out was very thorough and explained everything to us, and the work crew that came out was very fast. It was estimated to be a three-day job, but they did it in two. They were in and out and cleaned up after themselves, which was nice. When the inspector came out, he was also very thorough. He went over some things, like our downspouts, that we could do ourselves to help improve the water situation with our home. He explained everything to us well, and he didn't just lecture us on stuff. He was interactive, so we were able to ask him things, and he asked us things. I'd give them an A.”
“They fixed my basement a year ago, and it hasn't leaked since then, so that's positive. They came out, looked it over, and then we signed a contract. They came when they said they were going to, and they did the work in less time than they said. I had a friend who helped me choose them. I'd rate them as an A.”
“Even when something didn't work, they worked with me afterward to get it working properly. I had them do drainage work in my basement. They put a French drain in and an egress window as well. Their customer service was good, so they were very helpful.”
“They were able to come in quickly and get the basement waterproofing job done. They were friendly.”
“I wasn't there when they did the construction, but I had an agent of mine reviewing it. My agent said that they did what they were supposed to do and left, and the house was sold two months later.”
“They were straightforward and up front in their pricing. They did an inside French drain for me. I think I got them out of Best Pick Reports.”
“They came out and did the work. They resolved the issue, which is positive considering that's what they were hired to do, so I'm relatively satisfied. I don't have any catastrophic complaints about them because they did what they said they were going to do. They put a sump pump in and did some waterproofing. They were the third company I had out to resolve the issue. They finally brought a sump pump in, and I think that resolved the issue.”
“AquaGuard did waterproofing for me, and so far, the basement is dry. Their customer service was wonderful—outstanding. I would give the company an A rating. I really don't have any complaints.”
“It was an excellent experience. They dug a trench and installed a sump pump, and they did what they said they were going to do. I was referred to them by a neighbor. Their customer service was very good. They were very professional.”
“AquaGuard did a very good job. They put in a French drain in my basement—that was very well done—and they put in a new sump pump as well. So far, everything has been wonderful. I would recommend them.”
“I had work done by AquaGuard, and I was perfectly satisfied in every area of their service. I'm perfectly happy with them.”
“They did some work for me, and they were very professional. The job ended up being much bigger than expected once they dug the house out, but they did a great job getting all that extra work done very quickly. We talked with another company that tried to sell us a one-size-fits-all solution, but the solution AquaGuard provided was more effective. I would rate them an A+.”
“Everything was fine. They were very courteous, and they cleaned up very well after themselves. I can't think of anything that they did wrong. I would give AquaGuard an A+.”
“AquaGuard put in a sump pump, and they had to dig a trench inside my basement—the work was quite extensive. They came when they said they were going to come, they cleaned up, and the work was done well. They did an A+ job.”
“They did a sump pump for me—so far, so good. I liked their neatness. AquaGuard is an A+ business, and I have no complaints.”
“I liked that they were up front. They put a sump pump in the basement. We had a deal, and they stuck to the time frame that they said that they would work within. AquaGuard gets an A+.”
“AquaGuard installed a sump pump. I had one at one corner of the basement; now, the entire basement has a pipe leading to a sump pump. I liked everything they did. They were efficient, they cleaned up, and they got in and got out. It was very good. They're A+.”
“I had AquaGuard do some work for me a while ago. They put in a sump pump and a vapor barrier. They were pretty responsive, and they got the work done in the time that they said they would get it done in. I was happy with them. I'd give them an A.”
“I called AquaGuard because I had a leak in my foundation. They were thorough and quick. They get an A from me.”
“They put in a sump pump, dug out a trench outside, and cemented some areas. The salesman was very professional, and the people that did the work came in and did what they said they were going to do. I'd say they get an A.”
“AquaGuard did waterproofing for us when we had a leak. They showed up when they were supposed to, and they did a good job. It's not leaking anymore, so we are happy. I would say they deserve an A.”
“We had our crawl space done by AquaGuard, and it was good. I liked everything about them—they're an A.”
“They installed a French drain and two sump pumps. I thought they were efficient problem solvers. They were solution oriented, and I thought they were value oriented, too. I'd give their work an A grade.”
“AquaGuard was fabulous. They were very clean and very quick and did a great job. They waterproofed my basement. I chose them because they seemed very thorough and organized, and they gave a good presentation. I'd give them an A+, all around.”
“We had a problem, and AquaGuard worked with us. The service was excellent, and it was very professional. As far as the work and service—how everyone performed, even from the guy that came out to give the estimate, to how they handled everything on the telephone—they're an A+.”
“We had water in our basement, and AquaGuard fixed the problem. The workers were efficient, and overall it was a good experience. We've had a bad rain since and haven't had any more issues, so we're happy. They installed a French drain and a sump pump. I would give them an A+.”
“I was pretty happy with AquaGuard. In particular, they replaced the existing drainage system in our basement. They were excellent at explaining what it is that they were doing. The whole basement waterproofing business is very technical stuff. I like to think that I have a pretty decent engineering background, but a lot of that stuff is way over my head. They were the only company that was giving us all the details, but giving it to us in a way that was easy to understand. Everyone else was either talking over our heads or oversimplifying things. As best as I can tell, it's working great. We haven't had any problems since. Everything seems to be working in top shape. I'd give them a straight A.”
“I'm in an office building, and we were having water come into our elevator pits. These guys came in and put in their system so that the water would be pumped out into the drainage. They were very professional, they were quick about it, and they explained everything that they had to do. I would recommend them to anybody. The workers that they had here were really professional. I'd give them an A++++.”
“They're in the top ten, and they're the best work crew I've ever had in my home. They dug up my basement, they put in a new drain, and they put it all back together. They graded the yard so that water ran away from my house instead of into my basement. They were on time and polite, and they worked hard and fast. They cleaned up after themselves. I had not a moment of worry. They get an A+.”
“AquaGuard was very good. The service was right. Everybody was good, and it was quick. It was very good, and it passed the inspection. It was one of the best I've dealt with. I would rate them an A+.”
“The overall experience was great. They patched a crack in the foundation. They were very responsive and professional. They cleaned up after themselves when they were done. The customer service when I called in the first time was terrific. I would use them again. I'd give them an A+.”
“It has worked wonderfully. They did one heck of a nice job. They sealed up a basement wall, and they did a good job. They put glue on the wall, and it sealed the wall. I would give them an A+—no complaints. My overall experience was wonderful.”
“It was great. I haven't had any problems since. They were really friendly, and they did a really good job. They did it really quick—they were in and out in two days. The cleanup was good. They put plastic all over the place. I had one room where they had to cover all my furniture in plastic. They took all that stuff out and hauled everything off. There were no cracks or anything lying around. If I had the need, I would use the company again. I would rate them the highest I could—A+.”
“AquaGuard did a fantastic job. I watched them step by step. The workers were very informative. They told me what some other companies do to get around doing everything. I have to give them an A. They did great. If I had to recommend someone for waterproofing, it would be AquaGuard. They were fantastic.”
“They did an extra excellent job. I would recommend them to anyone who has a water problem. I liked the way the workers respected the house and cleaned up and made sure nothing got damaged. I liked the quality of work and workmanship, and I liked the respect they showed me as a homeowner. They get a double A.”
“They installed a drainage system in our basement. The quality of service was excellent. I would recommend them to friends and colleagues. I'd give them an A.”
“They installed a pressure-release system. The workers that performed the work were excellent. They did a good job overall, and they cleaned up after themselves when they were done. The customer service was excellent when I called in to get a quote. I would rate them an A.”
“They cleaned up after themselves. They were on time and got everything done in a reasonable amount of time. The workers were knowledgeable, friendly, and informative if I had questions. So far, there are no leaks. They're excellent—they get an A.”
“The work they did for me was excellent. They cleaned up after themselves every day. They put drains in all around, which meant they had to break up the cement floor in the basement and install that, cover it with gravel, and take away all the stuff. They were here for quite a few days. They did an excellent job. The overall quality was really good. Their customer service was excellent. I had no problems. I just called one guy, and everything was taken care of. AquaGuard is an A.”
“They did crawl space encapsulation. They seemed pretty hardworking and got the job done. I interviewed about ten companies, and their salesperson was the most professional by far; a couple of the other companies insulted me. We had a couple of to-dos, and they were by far the best. I'd give them an A.”
“I guess they finished the job on time—it took them one day. I had a leak in the basement, so they waterproofed it. They included a sump pump as well. I would say they did a good job on cleaning. They were very informative when they talked to me. I would give them an A. The surprising thing was that after they finished the job, they even took care of the musty smell in the basement as well. I don't know how they did it, but it was a perfect end to our leak.”
“AquaGuard was able to help me with my waterproofing last fall. It was done perfect. They put in an egress window for me, and it came out perfect. Their customer service was fine. That work has held up for me. I'd grade them an A.”
“They were very professional. They cleaned up properly. It was done all in one day, and I had been told it might take two or three days. I had a sump pump put in. I would absolutely use them again if I needed to. They were an A+.”
“They were very efficient and got the job done very quickly. Their customer service was very good. They worked in a crawl space and put in a French drain and sump pump to get water out from underneath the house. It's working, and it's holding up well so far. I think it was an A+ experience.”
“I've dealt with AquaGuard several times, and I've been happy with their work. Any time I had a problem, they were willing to come back and take a look and do whatever they could to make it right. They honored the warranty on their contract—that was a big deal. They didn't try to wiggle out of it. The very first time I called them is when I bought the house. I live in an area that they built on top of a stream. The first problem I had was getting water in my basement. They came over and put in a French drain, and they did some work around my steps. The second, most recent time I called them, I needed a new top on the part leading down to my steps. They sent somebody out to do that. When they did that, they found another problem. They fixed that and did the top. One of the problems was something that had failed from when they did it before. They went ahead and fixed that part. I would give them an A+.”
“They came in, did a great job, and were out the next day. I had a crack in the concrete foundation in the rear of the house. They had to seal that up. It had to be inspected by the county inspector, and they covered it up the next day. There has been no need for any follow-up services. If something like that happened again, I would use them. I think they guarantee it for 24 months or something like that. I got two other estimates, but I didn't like that they couldn't give me a guaranteed time for the repair work to be done, and winter was approaching. So, I went with AquaGuard. They definitely cleaned up well after their services—it was one thing that I asked up front—and the hole was covered up right. Everything was fine. I would rate them an A+. They did a great job.”
“The service they did was quite good. The work was done to my standards. They were very respectful and polite, and I didn't have any issues with the people who came to sell us the product or with the people who installed the waterproofing stuff. They sealed one wall in my basement. They had to dig it up and drain the walls underneath. Then they resealed it, put down some little black stuff in the wall, and replaced two sump pumps. Everything's been holding up well through all this crazy weather. I'd give them an A+.”
“AquaGuard did basement work, and they did quality work. They were knowledgeable. They get an A.”
“They did a modified French drain for us. They did it quickly, cleanly, and apparently well. We haven't had issues yet.”
“AquaGuard was very good. They did a basement waterproofing project. They did what they said they were going to do, and they did it in a timely manner. They cleaned up as much as you can for that kind of a project. I picked them because they had been in business for a length of time. I would give them an A. There was a small problem, but when we called in reference to the problem, they responded quickly and corrected it.”
“It was great. They put in two sump pumps and waterproofed my basement. I thought the workers that actually did the work were great. They were knowledgeable and friendly. They cleaned up after themselves when they were done. I guess the overall quality is fine. We haven't had any floods yet, knock on wood. I would recommend them. They get an A.”
