“We had a leak in the foundation and they did the inside and outside. An A rating.”
“They waterproofed for us. Probably an A-, probably an A. An A.”
“We didn't have any problems with that, we thought it was good. They did the water drain. They are good—A.”
“They did well. They redid my sump pump, the whole drainage. A's across the board. I would definitely recommend them.”
“It was waterproofing. I'd say an A.”
“Their care that they took with my home, the issue in general, and the promptness of the workers arriving, I appreciated that. They installed a drainage system sump pump in my basement—A.”
“They were responsive to my questions and concerns. They installed French drains sump pump system. A.”
“They completed the job quickly. They waterproofed my basement. I'd rate them as an A.”
“They did very good work, the work was completed in the time frame and everything was completed with no problems. They did some repair on an exterior wall for water proofing work. A grade.”
“They were easy to work with. They've actually done two jobs for us. They put in sub-floor pressure release system with a sump pump, and then they put in a yard drain system that tied into our gutters. I'd give them an A grade.”
“There's nothing wrong with them. My wife and I told them that they're the finest, most professional group of people—they're courteous and just the greatest contractors we've ever had in a day and age where contractors treat their customers like dirt. These guys treat you like a jewel. They get the job done, they get it done fast, and they are just about the nicest guys you'd ever want to meet. They do an unbelievable job. They're humble, but they're unbelievable. They did sump pump systems. Our house is on clay. I'm 57, and I've never dealt with a more professional team of people, ever. If there was an A++, I'd give it to them.”
“It was excellent service and excellent communication, and they did a great job. They did basement waterproofing. There were a couple of places in the basement that were leaking, and they also strengthened the wall. It involved excavating and repairing the outside in one place, drilling down in another for a drain, and then putting the Kevlar material on the back wall. I chose them because I liked their approach. I'd give them an A+.”
“The waterproofing, so far, is working. The person who talked with us was very eloquent and explained very well what they were going to do. We got estimates from different companies, and the guy who came over from AA Action was very good. It was great customer service; he followed up, and he was excellent. So far, I would say it was excellent—no complaints. So far, it's been working.”
“The experience I had was wonderful. They did a great job, and I haven't had any problems at all. They waterproofed the whole basement. I talked to a couple of other companies, but I just liked what I heard from AA Action. They were hard workers; they didn't mope around—they got in there and did the job. I'll give them an A.”
“We were trying to sell our house, and the basement showed signs of water penetration on the walls and coming up from the floor. They installed a system with a sump pump and a water drain system around the interior. They got it done, and we sold the house like a week later. They did a great job while they were there, so they get an A+.”
“They were very respectful and very courteous. They wanted to make sure that they did a proper job, and I would recommend them to anyone. I had to have a drain run around my house. I also had a cracked foundation, so they fixed that for me. Someone in the neighborhood told me to call them.”
“They came in and explained what was going on and what was happening. I had another waterproofing company come in, and they didn't drill the holes low enough. AA Action explained to me where the holes needed to be drilled, and it's working better than the last system I had in there. I can't argue about that. The crew was real good.”
“They did what they said they would do. They installed French drains and fixed our basement. A friend recommended them, and I would recommend them as well. They get an A.”
“They did what they said they were going to do, and everything seems fine. They waterproofed the basement; they put a French drain around the base of the whole house, came back in, put the piping in with the rocks, and then put the concrete back over top. They were very neat, and I was very satisfied. I would recommend them.”
“They were timely, and they explained their process well. It was a basement wall, so they did a French drain. I think they're probably an A.”
“They did basement waterproofing. They installed a sump pump and some kind of ditch. I'd rate them as an A.”
“Our basement no longer leaks. They were friendly. I would recommend them.”
“I liked the personnel and the way they performed the work. They were punctual, and I really liked the company. They put in a sump pump and a drain. I just liked his presentation.”
“It was a very positive experience. They were there when they were supposed to be. They were on budget and cleaned up after themselves, and the work they did actually works. They put a sump pump in the basement for me. They were the first ones to call back with any interest of doing my work. I would recommend them.”
“AA Action Waterproofing knew what the problem was, they were very professional, and they left the place really clean and nice. Water was coming in the basement when it rained a lot, and they told me they would solve the problem by digging a trench from the outside wall. They took care of that and replaced the sump pump, and everything is fine. They're very good—they know what they're doing. I'd recommend them. They're an A.”
“Everything was good. AA Action Waterproofing got there pretty quick, and they put in a French drain and a sump pump. I would recommend them. I'd rate them as an A.”
“The crew was efficient and did a great job. They put in a sump pump, and it was a good experience all the way around.”
“AA Action Waterproofing put in a new sump pump and new piping leading to the street. They get a good grade from me.”
“I liked that the guy from AA Action really took the time to explain everything to me. He told me the pros and cons of having my work done versus not having it done—I wasn't going to get a sump pump at first, and he said, 'No, this is why you should get one—why it would be beneficial to you.' As it turns out, it was best that I got it, because water runs down a hill toward my house. They were ready to start when they said they were, and they finished when they said they would. It was just a really positive experience. I would give them an A.”
“AA Action Waterproofing installed a French drain and a sump pump, and I never had to call them back. They were prompt. I would recommend them and give them an A+.”
“AA Action Waterproofing put in two sump pumps and redid my whole basement. They were on time, and they were in and out. Everything was good. I would give them a ten out of ten, an excellent rating, and an A grade.”
“They did a pretty extensive waterproofing job. They had good communication and professionalism, and they cleaned up their mess and answered all my questions. AA Action Waterproofing is an A+ company.”
“AA Action Waterproofing put in a French drain. I had some paneling on the wall, and they did the work in the basement without messing up my paneling, which was great. The guy was very honest about his opinions, and the crew showed up when they were supposed to and did an excellent job of cleaning up after themselves. When I bought the house, the inspector recommended them, and I'd definitely recommend giving them a call. They earned an A.”
“They did a sump pump, and it was good. The salesman was quite knowledgeable; he described exactly how the whole thing worked. They responded in a timely manner. I'd give them an A+.”
“They put my sump pump system in and did some waterproofing in my house. They did everything correctly—they came out and sized it up right, and they knew exactly what they were doing, so it was all a great experience. They told me exactly what I needed to know. I would give AA Action an A+ rating.”
“They put French drains in both my walls, and then they went down from the inside and put a sump pump in the corner of the two walls where water was coming in. I was very satisfied. It was just a good, fast job, and so far, it's held up good. They were very good—A+.”
“AA Action did some drainage work in the basement because I had some leaks from cracks. I liked their timing, they seemed to know what they were doing, and they knocked it out in the time frame they said they would—timing is always very important to me. They allowed me to come see the progress at one stage, and it was well explained. The sales guy did a great job of explaining what they would do step by step, so all I had to do was observe that they were actually doing what he said they would. We were one step away from signing off on the project with another company, but then we had AA Action come in, and we changed our minds. They're an A+ company.”
“We had some waterproofing done in the basement. We only had part of our basement done, so now we're having issues with water in other places, but because their warranty covers a certain area, they came back and did additional work to cover that as well. They had excellent customer service—they accommodated my schedule, and they were really receptive to any needs that I had. If I needed them to come back and fix things, they were very open to that. I'd definitely recommend them. I'd rate them as an A.”
“We had an indoor drain put in. They had to dig around the house, clean the downspouts and the gutters, use a drill to bust out the concrete lining around half the house's perimeter, and put in a drain to the sump pump they also put in. Then, they dug a trench to the side of the hill to get everything flowing away from the house. They were great. They addressed my needs, and they did it really quickly and very efficiently. It was customized to what I needed, even when I needed to make some last-minute changes. They were very easy to work with. They deserve an A+.”
“I hired them as a subcontractor. They put in a drain tile. They answered the phone on my first call, they responded to my request for an estimate very quickly, and they gave me a complete and professional response that included everything I needed. They set it up very near term, and they completed it on time. They did a neat job. I was very happy with my experience with them, so I would recommend them. They're an A+ business.”
“The service was quick, and they did a good job. I haven't had any problems with water coming into my basement.”
“They installed a pressure-release system in the basement, which included digging a trench underneath the walls to install some piping and a drainage system with a sump pump. Then, they put concrete back over it. They were honest—they gave me some pretty fair assessments of what kind of options I had, but they didn't pressure me to spend too much money. Also, they worked really hard and stayed focused. They got everything done in one day, even though they originally thought it was going to take two days. Altogether, it was a very positive experience. They get an A grade—they were excellent.”
“AA Action Waterproofing fixed two leaks in the basement. They were on time, and they did exactly what they said they were going to do. I have not had to call them back for anything. They get an A.”
“AA Action did waterproofing for me, and the quality of the work they did was OK. I would use their business again.”
“They came out promptly when I told them I needed to have an evaluation and an estimate. They delivered their service promptly, and they did a nice job doing what they were supposed to do. I basically did it because I was getting ready to sell the house, and I wanted to be able to sell the house with peace of mind that the basement wasn't going to leak again. They were nice people; they were easy to deal with and listened to my concerns. They should get an A.”
“AA Action Waterproofing put in a foundation drain on a single-family house, and they also installed some terrain to take the water away from the house. They did a really good job. I'd give them an A rating because it was great.”
“For the most part, the work they did for me was positive. The workers were good. There's been a little bit of water leakage, but that's because I didn't do the whole basement—I only did two walls. On very rare occasions like this last storm, I get a little bit of seepage from the wall that wasn't treated, but compared to what it was, I don't have any problems whatsoever from the treated walls; the fact that there's still a little bit of a problem is more my fault. I would use AA Action again, and I would recommend them. I'd grade it as an A.”
“AA Action Waterproofing had to put a new drainage pipe through the foundation. They did good work, and I would give them an A.”
“They did my floor tile and two sump pumps around the perimeter of the basement. Their work has held up fine. They get an A grade.”
“They put in a water drainage system underneath my basement's floor. They did a good job; I have no complaints so far. I would say AA Action deserves an A.”
“They fixed the puddle of water in my backyard. It was a job well done, and their customer service was very good. I'd give them an A rating.”
“I had waterproofing done, and I had the basement excavated—my basement is dry now. They did everything they said they'd do, and besides the fact that we had to wait on the city, they did it in a timely fashion. Everything was done accordingly, so I can't really complain. We needed to wait and and schedule them to come back out, but I think the company did a good job staying on schedule as much as possible, and the final product looked good. They get an A.”
“I definitely had a good experience with them. I called them out because of a typical basement leak. The water was coming from the bottom, and they had to figure out what to do. They installed a sump pump down there and went through everything with me just to make sure I understood what I was doing. The work has held up—they did some good things for me. I'd go with an A because it was just a pretty straightforward job.”
“I had an absolutely positive experience with them. They were fast and efficient, and they did what they were contracted to do. They were personable in the process. When I called and talked with them, I felt like they were the ones that could get it done. I'd rate them as an A.”
“They fixed some leaking in my basement. They were very timely—the time it took them to call, show up, give the estimate, and complete the work was all very fast. I haven't had any problems since, so the work was good quality as well. I would definitely recommend them. I thought the crew was good, and they cleaned up after themselves. They deserve an A.”
“AA Action did basement waterproofing. There was a problem, but they came out and fixed it in a timely manner. I would give them an A grade.”
“They installed a French drain in our basement, and they connected it to our sump pump, which they installed as well. It was pretty hassle free. They explained everything pretty well, and they cleaned up the place very nicely. I'd give them an A.”
“They put some French drains into the wall and into the floor. Whatever they did seemed to work. We had some storms, and we didn't have any problems, which was what I wanted. The experience was fine. They were very nice to work with. I'd give them top grades.”
“They did good work. I'd recommend them. They did what they said that they would do, and they stand behind their work—they gave me a dry basement certificate that I can pass on to the next person who owns my house. I would rate them as an A.”
“They did the drain tile on the foundation. They did good work, and they stand behind it. They were prompt and quick in getting the work done. I chose them because I had them do work in another part of my basement years ago. They get an A grade.”
“AA Action installed a perimeter drain inside my basement. Their solution to my problem was straightforward and explained very well, and they were prompt and very quick. Thus far, the solution seems to be working great, so right now, I would grade them an A based on everything I've seen.”
“They had to dig a trench along the base of the basement floor and install pipes that suction the water to a sump pump. Then, they put the exit from the sump pump outside. The job was done neatly and quickly. They earned an A for being on time and doing the work.”
“They dug out the perimeter of our house along the outside wall and installed a drainage system and a sump pump. They took their time, did a nice job, and didn't make a big mess. It seemed like they were proud of what they did. I'd rate them as an A.”
“AA Action waterproofed the basement. They came in, told me what they were going to do, and did what they said they would do in the time frame they said they would do it in. I would give them an A.”
“They put in a French drain, and as far as I know, it's working fine. We had a misunderstanding about how they were going to do the job and what the contract called for, but when I complained, they responded and fixed the problem—they strived to satisfy me. I'd say I would recommend them. They get an A-.”
“They repaired three leaks in the wall and put a new drainage system in a stairwell. They did a lot of work for me, and we're very satisfied with what they did. My daughter found their name, and she referred me. When the wall started leaking again, they were back out here working on it, and they didn't stop until the leak stopped. They were excellent; I have no complaints.”
“I had water leaking through my walls, and AA Action fixed that problem and put in a sump pump. I liked that they came out and did a good job, and they were professional. I haven't had to call them back since the work was done. They deserve an A grade.”
“AA Action Waterproofing created a system under the house to keep water away. They came when they said they were going to come, and they did the job they said they were going to do. They get an A.”
“We had to install a small special sump pump that would take water out of an area that they had to create because water was seeping under the wall. They were fine. The service representative went out of her way to try to help us out in a difficult situation.”
“AA Action Waterproofing sealed a wall to fix the crack in my foundation. They made sure that the work was done to perfection, and they addressed any questions or concerns I had. I've used them on numerous occasions—they're an A+.”
“AA Action Waterproofing was very professional. They installed a sump pump for me. They showed up on time and completed the work on time. They explained everything that they were doing, and they cleaned up afterward. They did an extremely efficient and professional job—A+.”
“I was very happy with my experience. Our basement has not leaked since. AA Action Waterproofing was very polite and clean. They actually dug a trench outside the house and repaired the wall inside and out. It looks great today. I'd give them an A.”
“They came within a couple hours from when I called them. They gave me a quote on the spot and had it repaired in no time. The footer was cracked, and it caused a crack in the foundation. They replaced the footer, reinforced it, and then filled in the crack. They definitely deserve an A.”
“They delivered on what they promised, and the system works. They put in a new drainage system and a sump pump in my basement. Their solution was the best alternate that was suggested to me. They deserve close to excellence. I'd give them an A.”
“They put a drain in for me. They came when they were scheduled to come, and they did the work that they were scheduled to do. They did everything neatly, and the crew was friendly and cooperative. Overall, it was just a pretty good experience working with them. I would give them an A, no question.”
“I liked their professionalism, and they were very efficient and explained everything very well. They put in a water heater. I haven't had to call them back. The work was fine. They get an A.”
“What made my experience with AA Action Waterproofing positive was the good job they did, and it was done pretty quickly. After the work was done, it's held up pretty well. They did not leave anything lying around. The cleanup was all good. If I had the need, I would use the company again. They installed a French drain and a sump pump for me. I would give them an A grade.”
“They were really fast about their work, and they did a really good job. They showed us everything that they were doing. When they dug out the foundation, they made sure to let my wife get pictures of everything so that we could have documents of the before and after. They were just really professional about the whole thing. They were repairing a crack in our foundation, and they waterproofed one corner of our house. They deserve an A+++.”
“They were very thorough. They made everything easy to understand. They explained every step, and they did exactly what they said they were going to do. The work was done in a timely manner as far as both the scheduling and the actual work they did. They cleaned up, and it almost looked better when they left than when they got here. They definitely deserve an A+.”
“I needed AA Action Waterproofing's services because I had water coming up from the ground. There wasn't a broken pipe; it was groundwater. They built a sump pump system in the room where I had the water damage. I did not have a sump pump before because it's on the ground level of my house. It's not a basement. Everything is good for me now. The company's professionalism and timeliness stands out. They got it done when they said they were going to get it done and for the price they said they were going to do it for. It was excellent with no complaints. I'd give them an A+ grade.”
“AA Action Waterproofing did work for me, and they did a wonderful job. The quality of the work was very wonderful. I would use the company again at any time, and I would give them an A+ grade.”
“The work AA Action Waterproofing did for me is fine. Everything is good and working. They were very nice, very helpful, and very good workers. They installed a pump system from one end of the house to the other. I don't know what it's called, but they broke into the cement, drilled holes into the cylinder blocks, and then it all goes down into my water pump. I didn't have a pump down there. The water was just gushing in. I spent hours down there trying to get this water out. So, they did a good job. I haven't had a problem since. That was the first time that I had them do work for me. They were an A+ grade. Everybody that was here was very nice and polite.”
