What Our Customers Say About Us











Kevin kept me updated every step of the way, even sending me photos of the old unit so I could understand what was going on from across the ocean. Once I decided to move forward with a full replacement, he skillfully handled everything, picked up the new water heater, installed it quickly, and followed up with photos of the completed work. (I’ve posted the before and after photos)
Before leaving, he left my mom his business card in case she needed anything else, which gave both of us peace of mind. The payment process was also seamless, they emailed me the invoice so I could take care of it directly, which was great because I didn’t want my mom to have to deal with any of it.
I truly appreciate the professionalism, communication, and efficiency Kevin and Discount Plumbing showed throughout the entire process. Highly recommend them if you’re looking for dependable plumbing service in San Francisco!
