Got a full system replacement with add-ons and some duct work. Evan was a great resource for figuring out the best way to handle our house, and Brian's install crew got it all done and detailed right on time. Everything was professional, quick, and clean from start to finish. Easily recommended.

Absolutely amazing experience. James gave the most extensive overview of my plumbing. He thoroughly discussed recommendations and sent a full report. He was not flustered or distracted by my dogs who showed great affection. James is a real people person taking in account my age and lifestyle when assessing my plumbing needs. McCullough made a great decision to add plumbing to their services and found a real gem by hiring James.
