Under-sink leaks in Rosemead
A warped cabinet bottom or a musty smell under the sink means water has been getting out for a while. Clear out the cabinet, take a photo, and send it to (310) 628-9399.
Find the joint that drips
Under a sink there are only a handful of places water can escape: the two supply lines, their shutoff valves, the trap nuts and the strainer where the drain meets the basin.
Dry everything with a towel, run the water, and watch. A drip that only shows while the faucet runs points at the drain side. A drip that never stops is on the supply side.
Shutoffs in older Rosemead houses
With a 1959 median build year, plenty of homes here still have multi-turn stem valves under the sink. They sit untouched for years, and the first time someone closes one, the packing nut starts to weep.
We can replace a tired stem valve with a quarter-turn valve on the same pipe, and swap old supply tubes for braided lines while the water is off.
Traps and strainers
Plastic slip-joint traps loosen as the cabinet gets bumped, and old chrome traps thin out from the inside. A strainer that leaks around the basin usually needs to be pulled and reset with fresh putty.
If the wood under the sink is soft or the wall behind it is wet, we point that out so it can be dried and looked at before it spreads.

Rosemead customers often ask
Is a small drip under the sink urgent?
It is worth fixing soon. Slow drips soak particleboard cabinets and invite mold before anyone notices.
Can you replace just the shutoff valve?
Yes. Swapping a stuck or weeping shutoff on the existing pipe is a common fix.
