Faucet & Toilet Repair in San Francisco, CA
Small plumbing problems are a constant in San Francisco's older buildings. Faucets drip, toilets run, flappers wear out and shutoff valves under sinks seize after decades of not being turned. Stacked flats mean a slow leak in one bathroom can stain the ceiling below, and condo buildings have rules about water shutoffs that affect neighbors. The city's water also plays a role: San Francisco's supply is very soft, which helps limit mineral buildup, but it is treated with chloramine, which can wear out rubber flappers and seals faster than people expect.
We repair and replace faucet cartridges, washers and aerators, fix running toilets by replacing flappers, fill valves and flush valves, reset wobbly toilets on new wax rings or seals, and replace supply lines and shutoff valves. We also install new faucets, toilets and garbage disposals, and our licensed plumbers take on the bigger connections when a fixture swap calls for them. We test every joint for leaks, clean up and make sure everything is working before we leave.

How a faucet & toilet repair visit usually goes
Find the Leak
We identify where the drip, run or leak is coming from and check the condition of valves, supply lines and surrounding surfaces.
Shut Off and Protect
We shut off water at the fixture or coordinate a building shutoff if needed, and protect floors and cabinets before opening anything up.
Repair or Replace Parts
We replace worn cartridges, washers, flappers, fill valves, seals or supply lines with quality parts suited to San Francisco's water.
Test and Clean Up
We restore water, check for leaks, test the fixture several times and clean up the area.
In stacked flats and condos, small leaks matter more because they affect neighbors. A slow leak from a toilet seal or tub drain can show up as a stain on the ceiling of the unit below long before you notice anything in your own bathroom. We pay attention to caulking around tubs and showers, toilet seals and the condition of supply lines, and we can help you catch small issues early. In older Victorian and Edwardian homes, we often find decades-old valves and supply lines that are ready to fail. Replacing them proactively is much cheaper than dealing with water damage later. Old pedestal sinks and clawfoot tubs in Haight and Noe Valley bathrooms often have exposed supply lines and decorative valves that are hard to find parts for, so we take time to identify the brand and source matching parts before suggesting a full replacement. In Sunset and Parkside houses, the laundry and a utility sink usually live in the garage, and the hose bibs and washer valves down there are worth checking too, because a failed washer hose can flood the garage floor and the storage on it. A quick look while we're already there is one of the easiest ways to avoid a bigger mess.
What shapes the price in San Francisco
Faucet and toilet repair cost depends on the type of fixture, the availability of replacement parts and how accessible the plumbing is. Common cartridges and toilet parts are quick to replace, while older or discontinued faucets may need a search for parts or a full replacement. Seized shutoff valves, corroded supply lines and tight spaces under old sinks add time. In multi-unit buildings, coordinating water shutoffs can affect scheduling. Bundling several plumbing repairs into one visit is the best way to make the most of the trip.
Neighbors often ask
Why do my toilet flappers wear out so fast?
San Francisco's water is treated with chloramine, which can break down rubber parts like flappers and seals faster than plain chlorine. If your toilet starts running again a year or two after a repair, that may be why. We use chloramine-resistant flappers and seals where available, which tend to last longer.
Can you fix a toilet that rocks?
Yes. A wobbly toilet often means the wax ring or seal has failed or the bolts have loosened. We pull the toilet, inspect the flange, replace the seal and reset the toilet securely. If the flange or subfloor is damaged, we repair or replace the flange, firm up the floor beneath it and reset the toilet so it stays put.
Do you replace shutoff valves?
Yes, when they're accessible and the water can be safely shut off. Older valves often seize or leak once they're finally turned. In condo buildings, shutting off water may require the building manager, so we'll coordinate that ahead of time.
Can you replace a whole faucet or toilet?
Yes. We remove the old fixture, check the shutoff and supply line, install the new faucet or toilet and test it under pressure. If the new fixture needs a drain moved, a new shutoff or supply changes inside the wall, our licensed plumbers handle that part, so you're not coordinating two companies. We're glad to install fixtures you've bought yourself, too.
Do you work on water heaters?
Yes. We check that a water heater has its required seismic straps and add or replace strapping where it's missing or loose. When the tank is leaking or near the end of its life, our licensed plumbers replace it, including the water, gas and vent connections, and the new heater gets strapped before we leave.
