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-.
