I searched online for someone to do the plumbing for my home renovation, and came across Sergio's Plumbing. I gave him 5 stars! You can tell he knows what he's doing, and it definitely shows how long he's been in the business. His team did great work, and at a great price. He even cracked great jokes!

Best plumber extremely knowledgeable and honest. I had a couple of other plumbers come out who lied about the work that needed to be done and were charging an arm and a leg. Then I found Sergio that was God sent. He was efficient and handled everything, plus he was affordable, didn’t take advantage like the rest of the plumbers. I am so grateful for him. I will always use him and refer him to others. Thank you, Sergio!
