Five Stars for 20/20 Plumbing - Doug is a Water Hammer Hero!
I've had 20/20 Plumbing out to my house twice now for persistent water hammer issues, and both times they've been fantastic. Most recently, Doug came out and absolutely crushed it! He quickly diagnosed the problem and expertly resolved it by strapping a pipe and installing a water hammer arrester. His expertise was clear, and we're so incredibly satisfied with the outcome. Highly recommend 20/20 Plumbing and Doug!

Reply from the business · Oct 10, 2025

We take a lot of pride in standing behind our work, and feedback like this truly means a lot to our entire team. We'll be sure to pass along your kind words to Doug—he’ll be glad to hear he’s a “Water Hammer Hero”! We’re glad we could get everything resolved for you.

20/20 Plumbing company is really good at what they do. Over the past few months specifically Larry and Frank have to been the biggest Help to me and the staff I work with. They are very knowledgeable and always responded quickly when requested. I highly recommended them you will not be disappointed.
