How we repair it
- Find the cause. We test the fixture, the drain and the valve to tell a supply leak from a drain leak or a failed seal.
- Explain the options. A worn cartridge or wax ring is a small repair. A failed shower valve or corroded pipe in the wall is a bigger one. You get the price before we start.
- Repair with matching parts. We carry common cartridges, flappers, fill valves and seals, and match older fixtures when possible.
- Test and clean up. We run water, check for leaks and leave the bathroom usable.
Why Los Angeles bathrooms leak
Many homes here were built with galvanized steel supply lines and cast iron drains that corrode from the inside, so older bathrooms often show low pressure and pinhole leaks. Hard water is common across Southern California and wears out faucet cartridges and toilet fill valves faster. In multi-story homes and apartment buildings, a leak in an upstairs bathroom often shows up first as a ceiling stain in the unit below.
Bathroom plumbing repair questions, answered
Why is there water on my ceiling under the bathroom?
The usual causes are a failed toilet wax ring, a leaking shower pan or grout, a drain connection under the tub, or a supply line in the wall. Turn off the water to that bathroom if you can, and call or text us so we can find the source before the ceiling is damaged further.
Why does my shower drain so slowly?
Hair and soap buildup in the drain or trap is the most common cause. If the tub and toilet are slow too, the branch or main line may be blocked.
Why does my toilet keep running?
A worn flapper, a fill valve set too high or a chain that's caught are the usual causes. They're quick repairs, and a running toilet can waste a lot of water.
How much does bathroom plumbing repair cost in Los Angeles?
It depends on the problem and how hard it is to reach. A flapper or cartridge is a small repair; a leak inside a wall takes more. We find the cause first and explain the price before we start.
Why is my bathroom water pressure low?
In older homes, corroded galvanized pipe is the most common cause. A clogged aerator or showerhead, a failing pressure regulator or a partly closed valve can also do it.
Is a bathroom leak an emergency?
If water is running onto a floor or ceiling, or you can't shut it off, yes. Close the fixture's shut-off valve or the main and call or text us at (323) 464-4700, 24/7.
Why does my bathroom smell like sewer?
A dry trap in an unused shower or floor drain, a failed toilet seal or a vent problem can let sewer gas in. Running water in unused drains refills the trap; if the smell stays, call us.
Can you repair an old shower valve or does it need replacing?
Many older valves can be rebuilt with new cartridges or stems. If parts aren't available or the valve body is leaking inside the wall, replacement is the better fix.
