Great work with sewer lines Mar 14, 2025

Cupertino has done great work for us in the past replacing sewer lines and water heaters. Not a huge company, so major jobs aren't recommended.

Very Satisfied with My Service Mar 8, 2023

Highly recommend these guys. Frank Cardia took time to verify the estimate in a professional and positive manner. He gave just enough technical information to understand that part of my sewer needed to be replaced along with the toilet. Work started right away and was finished before the estimated time they gave. The worker kept the house clean in the walkways and made an effort not to track dirt or water all over the house. Very satisfied with my service, and the completed work was excellent.

Highly Recommend This Company! Feb 3, 2023

We were having several calls to Roto-Rooter to clear a recurring clog in our pipes. The third time we called, we got a high quote from them to unclog our toilet. We then called Cupertino Plumbing. They were lower for the same job. They got it going, they felt that there was a further problem. They quoted us a further job to install a cleanout so the pipe could be inspected with a camera. They found water in the pipe, and it looked like the existing iron pipe had a sag in it where toilet paper could get stuck. We ended up having them replace the entire sewer line under the house, and they replaced a section of pipe in the front yard. Danny Perez was the technician that we communicated with. He was very informative and helpful throughout the entire job. The workers were very clean about the process and nice. They even provided pictures of the job. I highly recommend this company. We also had some grab bars installed in my 95-year-old mom's shower. We had asked several companies to come out and do this job. Cupertino Plumbing came through! My mom said the workers were very nice and she feels much safer!

Highly Recommended for Sewer Repairs May 12, 2022

As a representative for St. Jude's Church in Cupertino, I solicited a bid from Cupertino Plumbing for major sewer repairs. The bid was competitive with other bids received and was accepted as the best value. When additional repairs were discovered, Cupertino Plumbing rebid the new repairs at a reasonable rate and completed them in a timely fashion. As a church, we required special usages and an assurance that our system would have little disruption. Cupertino Plumbing was able to satisfy this throughout the period of repair. I recommend them highly.
