"Steve was timely and quick with replacing my water heater and was very responsive when I messaged him. He also provided great suggestions and options for my water heater replacement and streamlined the bayren rebates process for me. Provided services at a very fair price compared to other plumbing services. 10/10 would go to him for future plumbing issues."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Kenneth Asire Plumbing is the epitome of responsiveness, expertise, and great customer service. Our water heater failed and left my wife and me with no hot water. I used Home Advisor to get estimates, etc. Mr. Asire came out and gave us an estimate the next day. After obtaining two more estimates, we hired KAP, and we've never regretted it. Kenneth is extraordinarily knowledgeable, experienced, professional and courteous. The crew that he dispatched for the new water heater installation was great. The installation crew, Justin and Jerwin, were personable, clearly very experienced and did a marvelous job installing the new water heater and removing the old one. They worked very efficiently - from start to finish the job was completed in under two hours. We are very pleased with all aspects of our experience with Kenneth Asire Plumbing, would hire them again in a heartbeat, and recommend them very highly."

"Angel and Clever Plumbing team are the best! They replaced water heaters, repaired leaks, clogged drains and various other plumbing jobs. I highly recommend Clever Plumbing for any plumbing issues! He has helped me with multiple plumbing jobs, both big and small, and has always been great to work with. He’s very responsive, quick to schedule, and does a great job figuring out practical solutions. He’s reliable, knowledgeable, and someone I know I can count on when something comes up. I wouldn’t hesitate to call him again or recommend him to others, you will not regret it!"

"Called the same day as they sent the same plumber out that fixed the toilet last time.  Did a great job, quick & accurate.  Everything works great now, good for another 100 years!

"I just need a new toilet cover. Even the one I bought was not the right one. Sure felt like a klutz Lawrence got me another one and a nice wood one too and installed it immediately. I am happy and satisfied with the service and really appreciate the fast turn around."

"Great experience with In & Out Plumbing. Jose was incredibly helpful and knowledgeable while providing maintenance service on our water heater—he took the time to explain everything and made sure it was running smoothly. Alec was also fantastic in helping get everything set up and coordinated. Professional, efficient, and easy to work with. Highly recommend!"
