“Excellent work with no complaints.”
“They did my dining room faucet. They did a good job. I'd say the best grade. And they asked for no money up front, until they finished. I will recommend them.”

“All of a sudden, we had a lot of mold and water damage discovered in our basement area. They took care of it quickly enough and it looks like it's working too. So they did waterproofing. They had to put in a sump pump and dig a trench along the front of the whole basement and it works. They had to tear up a lot, but they left it in good shape. I'd give them an A.”
“AA Action Waterproofing was great.”
“They did a fine job, and I'd recommend their company.”
“They did good work, and they were timely. They fixed water coming in the basement, and they took some mold out as well. I would recommend them.”
“I had a positive experience. They just did good work and were in and out. They were efficient. It has rained since, and water hasn't come into the basement—that's pretty much all you could ask for. I think there was some mold remediation, too. I would recommend them; I already have. An A is fine for them.”
“AA Action Waterproofing was quite professional, and the work they did held up. We had a flash flood, and there was water all over my basement. We've had several flash floods since then and not a single drop, so I'm very happy that the problem is solved. The old water system was filled with mud, so they replaced that and put in a new sump pump as well. I would give them an A+.”
“They knew what they were doing. I had a little bit of water leaking in the basement, which had gone undetected because it was hidden by a bunch of furniture. The guy from AA Action had a very good idea of what it could be, and they came up with a solution for a cracked foundation. I was happy, and they gave me a guarantee. I'd rate them as excellent.”
“They were very efficient. They did waterproofing in the basement, and they did mold remediation as well. They get an A.”
“I would give AA Action Waterproofing an A+++.”
“The technicians from AA Action Waterproofing were punctual, clean, and professional. I think they deserve an A.”
“They did a good job. There was a slight problem with a pipe not being connected, but they came back out and fixed it, and they did that promptly. I would give them an A-.”
“After an earthquake, the belowground front wall started buckling a little bit, and we started getting water in the basement. They did a trench and put steel beams up to reinforce the wall. It would've been an emergency if we'd had more heavy rains, because the rain was saturating it and the weight kept pushing the wall in. Their work has held up, so we don't have any complaints. They had to replace the sump pump battery and do some other things—they took care of that. My wife did some research, made some calls, and got some recommendations; we called AA Action, and they brought in some photos of work they'd done around the area. They're A+.”
“There was some water in our basement, so they excavated and put in a drain to run the water out of the foundation. Then, they put some rock and other stuff down there and recemented it. So far, we have had no problems with the work; it's working out fine, so they did a very good job. They were very nice, and they were timely, so I would rate them as an A.”
“AA Action was terrific. They got the work done right away, and they were very efficient, very thorough, and very polite. They cleaned up everything, and I'd highly recommend them.”
“We had a series of problems, and AA Action addressed all of them in a timely and effective way. They had to gut the house and also remove the black mold that was developing pretty rapidly downstairs. They were very thorough and responsive.”
“We were very, very satisfied with the work AA Action did for us. They did a great job—A+.”
“AA Action did a great job on my house. I was very worried, and every time I called and asked for their advice, they were there to help answer my question. I would give them an A.”
“They came out at the right time and did the work fast. They were efficient. When I made a call to get service, it was easy, and they were very professional, especially the person working at the office. She was very good. I would give them an A.”
“They got straight to the point, and they seemed to know what they were doing. I was really happy with them. We had a basement with a leak, so they waterproofed the outside of the rental property that we have, and a little bit of remediation was done. I'm very happy. I would say they earned an A.”
“AA Action did what they said they were going to do, and there were no issues. I'd give them an A-.”
“The person from AA Action was very professional. They did a good job, and I was happy with it. I'd give them an A.”
“They put a French drain system in a portion of our basement. They were pretty prompt about coming out to look at the basement issues and give us an estimate, and they were able to fit us in pretty quickly for the repairs. I had to call them back for an indirect problem that wasn't to do with the drain; it was for another area of the basement that they'd done a little work on. Overall, my experience there was positive. They were fine when I called them back—they came out again, looked at it, and gave us an estimate for more work, but we elected not to do any more at the time. They did a good job. We haven't had a problem with flooding where they installed the drain. I'd recommend them, and I would give them an A-.”
