In San Jose, a plumber job driven by scope, pipe material, and how deep the problem sits generally runs $200–$6,000. This is a general range — always get itemized written quotes.
Small repairs like a faucet or running toilet are often a few hundred dollars, while repipes, sewer work, or water-heater replacement run much higher. Costs vary, so ask for a flat quote before work begins.
Minor fixes like a washer or aerator are DIY-friendly, but anything touching gas lines, main drains, or your water heater should go to a licensed plumber for safety and code compliance.
A silent toilet flapper leak or an underground supply-line leak is the usual culprit and can waste hundreds of gallons a day. A plumber can run a meter test to pinpoint it — repair costs vary with the source.
