"TJ, Joe, and the crew at Bob Oates were awesome in helping restore water service to our home when the water main between street + crawl space burst underground, flooding our garage. They acted quickly, thoroughly, and left our home in arguably better condition than before the pipe burst."

"Bob Oates team provided a sewer scope, a liner and pulled permits for me. Our house was in need of this service following an inspection that roots were getting into our pipes. We compared to another company and found Bob Oates to be more reasonably priced than others. The team communicated well and was quick to help."
