Let me start by saying that Ken Bidinger is a great guy and a really great plumber. He is neat and clean and arrives on time and leaves everything exactly the way he found it. And his prices are very competitive! I am a lifelong San Franciscan and have lived in SF all of my 60 years. I have had a lot of experience with various craftsmen in the homes I have owned here over those years, and I have rarely found one so competent that I would actually take the time to sit down and write about him. Specifically, he has done three fairly extensive plumbing jobs for me since I discovered him, and each one was completed with complete professionalism, including the delicate re-piping of the shower in the master-bathroom, which required some intricate work in the old walls of my home. I was worried about this job, but it came off without a hitch. I would recommend Ken Bidinger for any plumbing job, big or small. You’ll be glad you did. I won’t use anyone else!
