Kevin and his business deserves 10 stars. We had just moved into our new home and the day we finished renovating our kitchen .. I ran the dishwasher and started doing the dishes when we started hearing a "pipe leak" from downstairs. We were assigned a plumbing company with 1.5 stars through our home warranty company and decided we didn't want to take the risk and so I contacted 20+ plumbing companies. We are so grateful we decided to work with KP Plumbing. Kevin was quick to respond, super quick to come out, and very honest. He will be my go-to guy for all my plumbing needs from

I definitely recommend to consult with Kevin . He fixed my shower leak few months ago . It was difficult to find where the leakage was. He was very patient and professional. The price is very reasonable. I am glad that I found good plumbing service near my house

Friendly, personable, professional. The guys were competent, efficient, and worked fast. They handled requests with the greatest of ease and had great suggestions for when I didn't know exactly what I wanted. This was a last minute installation of an electric water heater. They praised my purchases on the water heater as well as the supplementary attachments that I purchased and installed them as well. The only thing they didn't handle was the electric portion of the job, which is understandable, they are plumbers not electricians. They did have a recommendation on a sparky, whom I hired
