This plumbing company is amazing. What a find. Had a pipe backup problem in my laundry room. I got their name from a neighbor who raved about them. They make it so easy on their website to request service. Quick, easy, painless. Wally came out the very next day. He explained what was going on, and the problem pipe was fixed! Not only that, but he saw a potential problem and told us how to handle it!!! We’re so glad we found Zest!!!! Would totally trust them to handle any plumbing need!

It started with Dianna the scheduler, she was amazing at deciphering the real questions that needed to be addressed. I am a new homeowner with a tankless water heater! She guided me to Len who was very good at teaching me all that I needed to know about this system. He went above and beyond and I really appreciated his honesty and ability to get to the bottom of the issue. Thanks!

Outstanding job. Wally is fantastic! Wasn’t cheap but replaced a failed hot water tank and corrected a number of things that were done incorrectly when my previous water heater was installed. Will use again.

I highly recommend Zest Plumbing. I made an appointment on-line at 7:00AM to have my failed water heater replaced and it was completed by noon the same day. The process was seamless and they went above and beyond to accommodate my needs. Jason Taylor the technician was fantastic, extremely knowledgeable and efficient.

Zest is now my company for all my plumbing needs. I have had several of the biggest names in the valley serve my property. Zest and especially Wally are the best- not even a close second. Prompt. Professional. Courteous. Respectful of property. Fair pricing. Solves the problem. What else is there?

Just a review to rave about our experience with Zest for the unfortunate happenstance that we needed new sewer pipes. A prior plumber ran ABS pipes into cast iron on a bathroom remodel and it caused a belly that needed a repair and replacement of the cast iron pipes. Anthony and Rabbaanee came to do the demo and pipe install. Those two men have revived my faith in modern day work ethic. They did an excellent job with a difficult demo in a very short time, installed the pipes, replaced the concrete and cleaned up all in 3 days. They were incredible and I cannot recommend them more highly if you need new sewer work or for any demo/replacement work with heavy lifting. Thanks so much guys!! Also had to shout out to Diana at the office who is always so on top of scheduling, billing and all things in the office. Thanks Diana!

Zest plumbing was great. They were able to make it to my house within an hour of my call. I had broke the shower valve in the wall and needed Zest to replace it. They were in and out in less than an hour. Wally was pleasant, efficient and knows his job! While no plumbing job is inexpensive, Zest was half as much as the Major local companies! I will only use Zest for any plumbing need in the future!

Fantastic Plumbing Company! I had emergency and they were able to send Wally out same day. In addition, he was able to quickly determine the problem, as well as the most cost effective solution. He also fixed another leak we had on the same visit, again, going the extra mile to identify the problem and find the best fix. He didn't try to create a mountain out of a mole hill like so many do today. I highly recommend Wally and Zest. A+++++
