We had Cupertino Plumbing replace all of our old galvanized and cast iron drain pipes, along with installing a new water heater and two new toilets. We are very happy with the work they did. It was a major multi-day project that required cutting holes in walls and ceilings. They were pleasant, professional, and responsive. Everything works great now, and the places where they patched the walls and ceilings look nice. A really good job. We definitely will call them for any future plumbing work.

This is a fantastic company (Cupertino Plumbing), I received excellent service from Mario. We texted back and forth on various questions I had regarding my kitchen water filter system and the airgap line for my dishwasher; he was always responsive. My previous plumber walked into our home without putting on booties and was unorganized, but Mario always put booties on his shoes which I appreciated, he was knowledgeable, organized, did very high quality work, communicates well, smiled a lot and was happy, and is now my go to guy for all future plumbing needs. Mario is best plumber I’ve known.

Cupertino Plumbing just replumbed our whole house and rebuilt our drainage system. They were efficient, communicative, and timely every day and went to great lengths to keep things clean and tidy. Every afternoon they would set expectations about the next day and every day they did what they say they would do which we very much appreciated. For big plumbing jobs they quality of workmanship and service can’t be beat.

Cupertino Plumbing is not the cheapest out there. They are on the competitive or expensive side. The reason to call them is for their outstanding professionalism, and the fact that they have a lot of people who can be there really soon when you need them.
