"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"

"Reported Kayan LLC/R. Lala to Consumer Protection. No respect for the elderly of parent of a disabled child. His masonry work was poor. Had to hire another company to repair the incomplete work. Did not glue on the caps that lay on the wall blocks, trim blocks to appropriate size and did not reinforce open gaps between the side walls and the floor pavers. Carpentry work was extremely poor job. He put up a ceiling under a deck, but did not make any provisions for installing a gutter or slanting the roof and the water accumulated between plywood and the outer panels. I had to hire a different contractor to remove these panels as they would have fallen on someone. Panels removed with one hand, leading to a downpour of accumulated water. He charged a miter saw and roofing nailer to my credit card and refused to return the tools and unused supplies. Quoted $3750 to powerwash and paint my handicap ramp in freezing temp and yelled at me when I refused. No remorse for his actions. "
