Everyone at Barker & Sons was beyond helpful. Ray went above and beyond our expectations and was very professional. So was Landon who came to help him with the install. I’ve had many plumbers here the last few weeks due to an overflow in my laundry room. Ray shined much brighter than the fellows from other companies. We will definitely be using Barker & Sons from now on.

Excellent customer service on top of high quality & professional work. The work was completed quickly and they hauled away the old water heater. Austin was very professional and did good work. Missy called the next day to ask if I was satisfied. You cannot fake a commitment to your customer. Both Austin & Missy were professional and sincere about doing the job right!

I only use Barker & Sons for my plumbing services. I always ask for Missy when I call. She is awesome! Super nice, understanding and sends out the right tech for the job. I’ve never had a problem with them. Always on time and get whatever I need done quickly. I LIKE THAT! I joined there member program which saves me 15% overtime right off the top. I LIKE THAT TOO! I would give these guys an A+++
