Rosenthal Plumbing is the only plumbing company we've ever used. The same goes for our neighbors. I wholeheartedly recommend their services. They've been in business in Santa Cruz for many years and have always done a good job for us. Rosenthal has re-piped our entire home. They replaced our water heater before its' warranty expired. They also replaced a water purification system. The purification system had an expired warranty but after speaking with Mr. Rosenthal, he replaced the system, only charging us for the plumbers time even though it was no fault of his that the system failed. One time, a Rosenthal plumber was here fixing a leaky bathtub faucet and noticed a fault in the old galvanized piping that might have continued leaking without discovery for some time. The plumbers with Rosenthal Plumbing are quite good at their job.
