Earlier today, our plumber JR Willis provided excellent, professional service and showed great knowledge of water filtration. He wasn’t pushy and took the time to guide my mom in the right direction. She feels comfortable moving forward with a new whole-home filtration system in the near future. Thank you, JR, for your patience and honest guidance.

CJ Jackson provided excellent service at our home! He was very informative about water quality and filtration, taking the time to explain everything clearly. He truly went above and beyond to make sure the job was done right. We’ve had other plumbers from Sierra come out before, but didn’t do anything similar to what CJ did. His level of care, thoroughness, and attention to detail stood out from the rest. We greatly appreciate his professionalism and highly recommend him!

I will definitely recommend technician ALPHREUS HARRIS if u want your home plumbing/water heater getting check. It was my first time getting my water heater and plumbing check and after checking sink, toilet, faucet, water line, and water heater he explained to me on what he saw and needed a attention and document them properly for me, and recommended what he think need to be replace or fix, and he explained what those thing can happen if they fail, he is a friendly guy and felt like not just a technician that its doing its job but instead a someone who really care on those home owners and make sure they have a safe place,
