“We recently had a drain back up into our basement and called O'Leary to inspect our plumbing. From the moment Nathan B arrived, the experience was excellent.
Nathan was professional, punctual, and took the time to thoroughly explain what he was seeing and what our options were. He answered every question we had and never made us feel rushed or pressured. What could have been a very stressful situation ended up feeling much more manageable because of his knowledge and calm, reassuring approach.
He worked efficiently, communicated clearly, and treated our home with respect. Most importantly, he gave us confidence that we understood the situation and could make informed decisions moving forward.
I would not hesitate to recommend him to anyone looking for honest, professional plumbing service. Thank you for making a difficult situation much easier to navigate.“

I have dealt with Adam the last couple of summers, he is always willing to take the time to explain things and teach things about how my air conditioner works.

“Two ambitious projects in the past year: 2 new replacement boilers and 2 new air conditioning systems. All four were professionally installed, at budget, and on time. The high pressure A/C is unobtrusive, and the new heating takes up maybe 20% of the old system. Special shout out to Brian, Larry, Carl, and Tim. Quite a crew.“
