"Very happy that we decided to work with Kyle and Hyper Flow. We had a water main leak that flooded our basement and our sump pump was not working. At 7 months pregnant, I could not go without running water to the house and needed this fixed fast. Kyle came out to provide an estimate on a Monday and the work was completed by Wednesday. He provided the most reasonable estimate for getting the work done in that quick time frame. Kyle was professional, on time, and responsive with communication."
