A dripping faucet wastes more water than most people realize, and it is usually one worn part rather than a sign the whole fixture needs replacing. A slow kitchen or bathroom sink is often a separate, simpler fix.
Why Faucets Wear Out Faster In Altadena
Hard water across Altadena's mutual water company service areas leaves mineral scale inside faucet cartridges and aerators. That buildup is a common reason a faucet starts dripping or loses pressure years before it should.
Any replacement fixture installed in Altadena has to meet California's lead-free requirement under NSF/ANSI 372, part of the state's AB 1953 framework for fixtures carrying water for human consumption. We only install compliant parts.
Older homes with original fixtures from a prior remodel sometimes have supply line connections or valve types that are no longer common, which is worth checking before assuming a modern replacement faucet will connect without an adapter.
Common Faucet And Sink Problems
Persistent Dripping
Almost always a worn cartridge or valve seat, not a sign the entire faucet body has failed.
Low Flow At One Fixture
A clogged aerator from mineral buildup is the most common cause of reduced flow at a single faucet.
Leak Under The Sink
Usually a loose or corroded supply line connection, distinct from the faucet itself.
Handle Hard To Turn
Mineral buildup inside the cartridge can make a handle stiff or cause it to stick in one position.

How We Diagnose It
Most dripping faucets are diagnosed by pulling the handle and inspecting the cartridge or valve seat directly for wear or mineral scale, rather than replacing the whole fixture on assumption.
A leak under the sink gets traced to its exact connection point, whether that is the supply line, the shutoff valve, or the drain trap, since each has a different repair.
For a kitchen sink with both hot and cold sides affected, we also check the shared shutoff valves themselves, since a valve that no longer seals fully can mimic a faucet leak even when the faucet itself is fine.
Repair Or Replace
Usually Repairable
A dripping single-handle faucet with a worn cartridge, or a clogged aerator restricting flow.
Usually Replace
A faucet with a cracked body, a discontinued cartridge that is no longer available, or persistent leaks after repeated repairs.
Supply Line Fix
A corroded or loose supply line connection under the sink is a separate, usually inexpensive repair from the faucet itself.
What Affects The Cost Of Faucet & Sink Repair
Scope Of The Problem
A straightforward, isolated repair costs less than a job involving multiple fixtures or a harder-to-diagnose root cause.
Parts & Materials
Fixture quality, pipe material, and whether a part needs to be special-ordered all factor into the final price.
Access & Location
A repair behind a finished wall, under a slab, or in a hard-to-reach crawlspace takes longer than one with open access.
Timing
Standard daytime scheduling costs less than an after-hours or weekend emergency dispatch.
Homeowner's insurance often covers sudden, accidental damage like a burst pipe, but typically does not cover gradual wear, an aging part failing on its own, or deferred maintenance. Check your specific policy for what it actually covers before assuming either way.
These factors explain why prices vary. For your exact number, call (626) 898-6169 and describe what you're seeing, we'll give you a flat price before any work begins.
Common Questions
Why does my faucet still drip after I replaced the washer myself?
Modern faucets typically use a cartridge rather than a rubber washer. If the cartridge itself is worn or scaled, replacing a washer will not fix the drip.
Can hard water really damage a faucet?
Yes. Mineral scale builds up inside cartridges and aerators over time, which is a leading cause of dripping and reduced flow in this area.
Do new faucets have to meet a specific standard in California?
Yes. Any fixture carrying water for human consumption must meet the NSF/ANSI 372 lead-free standard under California's AB 1953 framework, and we only install compliant fixtures.
How long does a typical faucet repair take?
Most cartridge or aerator repairs are completed in under an hour once the fixture is diagnosed, though a full faucet replacement can take longer depending on the connections underneath.
Before We Arrive
- If a supply line under the sink is actively leaking, close the shutoff valve beneath the fixture, usually located directly under the sink.
- Note whether the problem is a drip, a leak underneath, or reduced flow, since each points to a different part and repair.
- If you have a preferred replacement faucet in mind, having the model or brand available helps us confirm compatibility before the visit.
