Customer Reviews

See what customers have to say about their experience with Caldwell Plumbing.
Appreciate Drew and his plumbing knowledge and determination for replacing kitchen cold water valve and 2 shut offs. Thanks for a job well done. You guys are my condo plumbers going forward!

A pipe in my ceiling was dripping lots of water, filling up buckets, and this was the Thursday before a long weekend. We gave Caldwell Plumbing a try: first thing Friday morning, Kim, the helpful sales staff, responded to my message from the night before, and sent someone out by the early afternoon! Carter, our friendly, efficient plumber, was a very clean and tidy worker. He was even able to recommend someone to fix our drywall (again, through Caldwell). The price was reasonable, considering that it was the Friday of a long weekend. Highly recommended
