Hear From Our Satisfied Customers

“Working with O’Neill Plumbing was great. We had a leak in our main water line which was a huge crisis for us but they were very responsive when we reached out to them. Overall it was a great experience from start to finish. Great customer service and amazing clean up after the work was done. They managed to somehow make a terrible situation a lot better.”

“Absolutely the best crew ever! Honest, professional, thorough and dedicated to achieving the best outcome. We had a complicated water line repair — and the Underground Crew was unrelenting in making sure it was repaired properly. I so appreciate their integrity and commitment to delivering excellent work. They went above and beyond in every way from the discovery, repair recommendations, follow-through and clean up, even laying grass seed where the yard was affected. I was so impressed!”
