Hear From Our Satisfied Customers

“O’Neill is excellent! This is the second time we’ve used their services and they are top notch. Bobby coordinated a fix for a leak in our front yard while we were out of town. Mike, Cody and Jesus completed the work quickly so that we had water again when we returned from our trip. All around friendly team and they did a spectacular job with the repair and cleanup.”

Alexander P.Seattle

“We are in the process of building a DADU on our property and were worried about our sewer line as it connects with our neighbor’s line so we had O’Neills come out to do a full scope. Bobby came out today-was right on time, and so friendly and pleasant to work with. He pulled a full sewer map, and was able to explain to me exactly what was happening with our line.”

Heather S.Seattle

“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.”
