Hear From Our Satisfied Customers

“I just had O’Neill back out to replace a toilet. Jordan showed up on time and got the job done professionally and on budget. No surprises, which I appreciate!”

Jeff S.Seattle

“Ricky, Hunter, Tyler and the crew at O’Neill Plumbing are great. They worked on my kitchen and bathroom renovation and continue to come fix my plumbing issues. They’re responsive, communicative and I feel like they know my home well. I trust them! They just fixed a super stubborn toilet clog after I tried with my auger and they fixed it for me.”

Chihana S.Seattle

“Toilet and bathtub were backed up. Veteran plumber Nelson pulled our old, cracked toilet, snaked the line, cut out a tree root, rooted the line clear to at least 100 feet, then installed a new toilet – no time wasted. He also gave me advice on how to keep our kitchen drain clear. This man knows plumbing inside and out.”
