First Response Waterproofing did a wonderful job fixing our basement. Reza and his crew are very knowledgeable, professional, and do what they promise. We could always count on them. They were also very kind and patient, and willing to do what we asked of them. Reza was always accessible, always answering my calls, and always came out, or sent his crew as promised. I highly recommend them to anyone in need of a dry basement.
