 Verified I've been in the bay area for 10 years, and there are few people I would recommend as highly for anything as Doniel! He helped us years ago when our water heater sprung a leak right after we moved into our first home and helped a clueless family navigate that problem with ease and confidence. Then when a particularly difficult to solve issue happened recently, he was quick to respond and went so far above and beyond what I would expect from anyone to help until not only it was fixed, but he also taught me so much about my own system and how it works and to fix it. I and my entire family can not thank you enough!!!!

 Verified I had a great experience with "Just In Time Water Heaters". Doniel showed up the next morning with a new 50 gallon water heater after I made a call at 9:30pm and left a message the night before. He returned my call within 5 minutes! He arrived on time and called me 30 before his arrival. He was very friendly, knowledgeable, professional, and installed my new water heater within 2 hours. His communication was excellent from start to finish. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call "Just In Time Water Heaters" and ask for Doniel. Highly recommended!

 Verified Called for repair of the ignition on our 12 year old Natural Gas Rheem tank heater.  Dispatch was prompt, Doniel arrived on time, showed us the corrosion on the existing tank, and recommended replacment.  The price for a new 40 gallon Bradford & White was fair and he completed the work while ensuring the tank was properly vented and strapped and added a new catch pan.  Very happy with the service and value.  I'm glad to have replaced this aging unit before it started leaking!

 Verified This guy was the first local plumber to answer and respond to my call and could quickly replace our old water heater that had obviously failed and was leaking all over our garage floor. He identified the issues that needed to be brought up to code and improved the water heater installation and ventilaton, and so I trust the quality of his work as well. His quality of work and his attentiveness lives up to his businesses name. He also explained his reccomendation of water heater brands and the relative quality between an american made Bradford White water heater vs the other brands sold at Home Depot and Lowes. He wasn't the cheapest option available to us, but he stands behind the work he does, so that is worth something to me.

 Trustindex verifies that the original source of the review is Google. I called for a leaking water heater and Doniel provided a fair quote and was onsite within two hours with a new water heater. Previous water heater didn’t have adequate bracing, and he took the time to properly secure the water heater to the wall. He cleaned up after he was done. Will call Doniel again for future services.

 Trustindex verifies that the original source of the review is Google. Doniel is the absolute best! He went so far above and beyond in trying to diagnose and fix a particularly difficult to pin down problem with our water heater system that I'm honestly still blown away by his work ethic, determination, and kindness. Work was done timely, always in close communication (even trying to explain what he was doing to my son!), and he was not satisfied until not only was everything working, but was checking in days later to ensure that everything was still good. I can not recommend him enough!!!!

 Trustindex verifies that the original source of the review is Google. If you’re looking for an honest plumber that is straight up about issues, surrounding your job, “just in time” plumber is top notch. Danielle was professional and got straight to the point on my job. Hired him to install new water heater and a few minor plumbing jobs. was clean and took his time to do the jobs right the first time. I highly recommend “just in time”

 Trustindex verifies that the original source of the review is Google. The owner, Donnell, was easy to work with. He clearly explained what he needed to do to replace my hot water heater. He knew exactly what he was going to do, how long it would take and communicated everything that I needed to know, with confidence, in a matter of minutes. I would highly recommend him.
