We have used Zest for many of our plumbing issues. The last time the initial work lead to other issues. We contacted them and told them of our displeasure. They listened to our concerns and promptly corrected all issues. We appreciate their commitment to fixing the issues and the final pricing. We will continue to use them for future work and would recommend them to anyone with plumbing issues.

I had a major water leak and had to shut off all water to our house. I had previously had another plumber out to give me an estimate. I got a bad vibe from him with his negative comments trying to sell me a whole new line. Wally, from Zest Plumbing, came out very quickly when I called and instantly put my mind at ease. He was kind and professional and gave me an Elderly/Military discount for having already dug out the area to expose the problem! And, he made me feel great when he expressed his amazement that I could do that at 85. (Incidentally they were cheaper than the competitors even before the discount!) I will definitely call Wally again if I need a plumber. He cleaned up the area before he left and treated me with respect rather than trying to put one over on me. Thanks, Wally!

Our water heater started leaking on Monday night. Gave Zest a call and they promptly scheduled an inspection Tuesday morning. They came out when they said they would and got a new water heater installed with no problems. I also had them put in a check valve on our hot water recirculating system to prevent hot water getting into the cold water supply. Very pleased with their service. We have used them before and will continue to do so.

I have used Zest 3x in the last year. Jesse came out this time and was quick to diagnose and repair the problem. He also checked a few things while he was here which I appreciated. Great and efficient service. Thank you Zest.

Zest Plumbing is great! I really appreciate that Zest doesn’t charge you a fee to come out and assess your plumbing issue - you pay only if you decide to hire them for the job. Len is extremely knowledgeable and professional - he helped us with our plumbing issues, gave us great advice, and did outstanding work. He is now our go-to plumber.
