Hear From Our Satisfied Customers

“Ricky to the rescue when our sewer pipe backed up! He’s knowledgeable, a nice person, and was persistent and expert with everything involved. He got our line snaked and stopped the immediate crisis. We will also look at O’Neill for our long-term solution. We value their good service and expertise.”

“I called O’Neill at 5:30p Thursday, and Ricky and his assistant Hunter arrived 8:30a in Friday. Our sewer was clogged (5th time since 2001), the were very efficient at diagnosing and unclogging. It took three hours, but our sewer line has never been cleaner. Awesome quality and attention.”

Ben S.Seattle

“We had our main sewer line replaced. The O’Neill team was the most professional and conscientious group I have ever had the pleasure of hiring, and also a great group of people. They were like surgeons operating in my small yard. When they finished, the garden looked better than before they started! I highly recommend O’Neill Plumbing.”
