"What can I say about American Dry Basement Systems? A few years ago, our area experienced an extraordinary amount of rainfall. My backyard looked like a pond, and water was rising all the way to the back of my house. At the time, there was already some water in the basement, but I believed I had a solid plan in place to manage it—completely unaware of the damage that was about to unfold. The next day, I went downstairs to check the situation and was devastated to find nearly four feet of water filling my basement. Storage totes were floating, along with irreplaceable family artifacts that meant the world to me—pieces of history from loved ones who are no longer here. I immediately tried contacting the fire department, but I wasn’t alone in this situation; many others were dealing with flooding as well. With no other option, I had to purchase another water pump. After a grueling 10-hour ordeal, the water was finally removed. Unfortunately, the damage was already done. I lost cherishe"

"CT Basement systems did a wonderful job on the walls that were flood damaged. Their overall system is great. We didn't need the total renovation but if we did, we would certainly have had them do it. After researching others, this was the best."

"My review of the work I have had done by Thomas Gianni & Sons Inc.. They really did a great job of working on my property. I call their office and asked to get some excavation of removing a couple of tree stumps in my yard and to put down approx. 20 yds. of gravel in an area near my shed. It was just about three or four days and they call me back to confirm to come out the next day, June 22. Their employee came by early in the morning and went over all the project. Figured out what equipment he needed and measured up for the materials and started the work about an hour later. He was very cautious and caring about minimal damaging to the yard. After removing the stumps he graded the surrounding area with the machine to the point where I only needed to rake it out to plant new grass. The gravel was put down flat and clean; not a mess. I would definitely hire them again."
