Plumbing services by Dempster Plumbing in San Jose, California

I live out of town and was in need of a good plumber in San Jose, as my tenants reported a major sewage backup reoccurring for a second time in over a week, which caused flooding to occur under the master toilet and all over the bathroom floor. I had been working with a plumber sent out by my home warranty company that had been onsite for over a week, which supposedly replaced my main sewer line and the water heater. I was desperate to find a reputable plumber to go over and give me a 2nd opinion but I didn't know any. After reviewing San Jose Plumbers online on Google and Yelp, I selected Dempster Plumbing based on their “All 5 Star Reviews”. I called the company number around 7am and Bill Dempster, the owner answered. I told him about the backup and asked him if he would please go out to my rental property and access the problem. He agreed and arrived with his crew by 11 am. By noon Bill Dempster called me and reported to me all the plumbing problems, as well as sent me pictures via text of all that needed to be addressed. Within hours Dempster sent me a quote, pulled the required permits to fix the sewer line and the new water heater that had just been installed by the home warranty plumber. I found Dempster Plumbing and his entire crew including their office staff to be, professional, honest, experienced, reliable, and fair priced along with delivering excellent customer service - A rare find these days! Anytime I called or texted with questions, I received an immediate response from Bill. If you're looking for a plumber with all those qualities and who genuinely takes pride in their work, then I wouldn't hesitate to recommend Dempster Plumbing for any major or minor plumbing needs as Bill Dempster is a licensed plumbing contractor that does the job right the first time - all work is done to code and with the required city permits. I feel very fortunate to have found Dempster Plumbing Company as my Plumber. No more Home Warranty Plumbers for me!

Updating my review - I have used Dempster Plumbing for five projects now. The latest is an entire kitchen remodel requiring a new gas line, electrical, flooring - the works! They did an amazing job in a very short period of time at a very reasonable cost. I am EXTREMELY happy with their work. Bill, Val, Sam and the rest of the crew always make sure we are 100 happy with the results. I highly recommend Dempster Plumbing.

On time, local and relatable. I had a 9-10 AM appointment and they showed up just after 9. Took care of the problem efficiently. I didn't even shop them since they have 5 rating and I'm glad I didn't.
