"Jose came out to trouble my 6 year old water heater which stopped heating and would not respond to my efforts. After a long and thorough attempt to fix the situation, the heater declined to participate. Jose outlined my options and explained in detail what he wanted me to know before deciding to purchase a new system. Once I decided, Jose worked out a plan for me. He made sure his supplier was open on Christmas Eve so he could pick it up and install for me the same day. Jose returned early the next day with his partner to change out the old system (from 2nd floor) and haul the new tank up those pesky stairs. Super Heroes, absolutely. They worked diligently until the job was completed. Jose explained the features/answered my questions and gave me a very fair price. I definitely plan to call him for future needs. He's the best. I sincerely urge you to call Jose for your next plumbing debacle. Kudos. -- Dawn"

"Satisfied customers reporting! We're writing this review four months after the completion of our bathroom renovation. We've been thrilled with the final product and the experience of signing with Ouri from day one was a pleasure. This was our first large project and we would undoubtedly hire Ouri again. Project We instinctively knew Ouri was the best fit for us after the on-site consultation. Not only are his reviews overwhelmingly positive, but he's knowledgeable, respectful, patient, and honest, with competitive pricing to boot. He's also a very responsive communicator. We needed some time after signing the contract to shop for materials. Ouri kindly rolled with our uncertain timeline, checking in periodically without any pressure to see where we were at and advising on any questions we had along the way. From the beginning of the project, his crew was respectful, clean, and always checked in with us as any questions came up. The project went smoothly and for one very minor hiccup that came up, Ouri & crew were quick to address without question. And months later, he sent a member of his crew to come troubleshoot something minor, again without any hesitation. It's challenging to keep these brief when you have such a great experience, especially when you read and hear about horror stories from other people. Selfishly, maybe we should keep this to ourselves so he isn't so busy when we need him for another project in the future :) Scope The bathroom was totally gutted save for some sections of drywall. A full tiled shower with a bench was installed (replacing a tiny old corner unit!), along with added lighting & exhaust fan, new floor tile, and all new fixtures/ cabinets/ paint. The plumbing and the shower drain were relocated. An old window was removed and replaced by a new one on an adjacent wall."
