Meet Andy: British Roots, Bay Area Heart
"I didn't just learn plumbing; I mastered it in the U.K. trade schools, where 'good enough' was never an option. When I immigrated to the U.S., I brought that Old World dedication to craftsmanship with me.
Adapting to California’s plumbing codes was a new challenge, but I saw an opportunity to offer something different: a plumbing service built on British precision and unwavering respect for your home.
Starting Comet Plumbing in Sunnyvale meant long days and proving myself one job at a time. Today, my background is my superpower. I built this company to fight the "messy plumber" stereotype, ensuring every job is done with a clean van, fair flat-rate pricing, and the handshake of a neighbor you can trust."

WHAT PEOPLE SAY
Comet plumbing did a excellent job at my home . A fair price, competent, knowledgeable, efficient , clean and professional! Thank you Andy, I will be calling you for future issues if needed.
We had a drain issue right around the holidays and Andrew fixed it that same day. He and his team have always done great work at a fair price!
Andrew from Comet Plumbing was wonderful! He helped install two clean-outs and fixed a root infested pipe for a reasonable price (plus nice discount). I’ll definitely be using them again!
Great service from Comet Plumbing. He was super busy but still managed to come over the same day I called and do a faucet install. I provided the faucet, but not the hoses - not to worry, Comet had all the parts that were not included. The shut off valve needed replacing, and they had that ready to go as well. Highly recommend.

The best, most reliable and most honest plumber you will find. I have had Andrew do a number of jobs for me and the price was always reasonable and the work quality. He stands behind his work. It took me many years and iterations of using different plumbers with sometimes bad results before I found Andrew, so I consider finding him a gift.
After speaking to 5 different plumbers about replacing my sewer pipes, I picked Comet Plumbing for the job. From the time we first met, I found Andrew to be honest, knowledgeable, and responsive. Make no mistake, Andrew knows his stuff when it comes to sewer plumbing. The work was explained in detail to me and performed to my satisfaction. His crew was top notch, especially being able to work around a section that was particularly cramped. He made sure the system was fully tested for leaks and answered all my questions. Thanks again, Andrew, for a job well done.
