"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Their service is expensive, but they are very responsive, efficient, and thorough. The plumber who came also taught me a great deal about how to prevent future problems. Overall, I was very pleased with their service."

"They kept me appraised of their schedule. They did some troubleshooting over the phone and were able to get my water on before they arrived. When they discovered the problem, they walked me through it step by step so I knew what was going on and what needed to be done. I really appreciated that."
