About Knockout Plumbing & Repipe Inc.

Knockout Plumbing & Repipe Inc. provides reliable and high-quality plumbing installations in the South Bay area. With 40 years of combined experience, their office staff and technicians work together to take on any plumbing task. They use the best materials available and prioritize quality in each installation.

Recent customer reviews highlight their professional service and efficiency. One customer experienced a plumbing emergency when water was pouring out of their meter box. They called Knockout Plumbing, and the team responded earlier than expected. Martin assessed the problem and dispatched Kevin, who completed the repair quickly and returned later to turn the water on. Both Martin and Kevin were praised for being respectful, knowledgeable, and friendly.

Another customer noted that everything was fine during their visit, mentioning that the plumber was courteous and friendly. However, they found it unusual not to receive a written invoice on-site. After contacting the office, they received the necessary paperwork via email.

In another instance, a customer had a broken kitchen faucet and called for help. Kevin provided a fair estimate without trying to take advantage of the situation. After a week, when the parts arrived, Kevin returned and performed a very professional job. He was noted for being polite and respectful, and the customer expressed a willingness to hire him again. Overall, Knockout Plumbing & Repipe Inc. aims to provide turn-key solutions for any plumbing needs with a happy, loyal, and satisfied customer in mind.

Anthony spent many hours fixing a leak with our bathroom faucet. He was always very honest and approachable, explaining what problems he encountered and what the options were. I wouldn’t hesitate to have him address any other plumbing related issues in the future.

I HIGHLY recommend them!!! We had a major plumbing issue on the weekend and couldn’t use the water at home at all , when I called them, they were very supportive and had their crew available within 1 hour.

The professionalism, ability to understand my panic and then to help me… I have not seen such support from any other provider.

Thank you so much!

I had pipe hammering issues. Jason was super honest about expectations, had a reasonably priced fix, and he was able to get it taken care of in a few days in just under two hours. He was also super respectful and efficient. Appreciate it!
