"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."

It is so refreshing to hire someone who possesses such high standards of professionalism and curtesy. I highly recommend Larry's Legacy Landworks. They consistently do the work that was agreed upon within the agreed timeline."

"Cyrus was able to help me right away when I called him at 6pm on a Tuesday evening. He charged more than other companies quoted, but he was the only one who was willing to come after hours, and with a blocked sewer main, that was the most important thing. Very grateful for this company."
