“I had groundwater coming up into my house, and they did the job in the time frame they said they were going to do it in. They gave me a professional estimate, and I felt confident that they were going to do the work the right way. I'd give them an A.”
“They did a good job. It was excellent work, and I would recommend them.”
“They did a very nice job, and I'm very satisfied. I would give AA Action Waterproofing an A+.”
“AA Action was good, very communicative, and fast. We had an emergency situation, and the work was done well. We had a basement flood and severe leakage issues, so they installed a French drain, installed a sump pump, and worked on the walls. I would give them an A rating.”
“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.”
