I had the pleasure of dealing with Charles, Arthur, Richard, Justin and Ian. Richard and Arthur took care of the installation. They were efficient and very respectful of my home. It was a pleasure to engage the McCullough team. Great people, great culture.

James and Will are the plumbing dream team! One of our water heater tanks was on the verge of disaster, and James patiently helped me assess our options and expertly answered my countless questions. James’ clear and prompt communication prepared me for the work planned, and the installation of our new tankless system was smooth and efficient. James also took the time to explain in detail the new system and how to maintain it for years to come. Thank you, James, Will and the McCullough team!

I was happy to hear McCullough added plumbing services since I've been happy with their AC work and I know they care about their reputation. Will was very thorough and knowledgeable when he did my free inspection.

He did a great job and cleared up our a/c drain lines well and gave me a few pointers.
