Low water flow at a kitchen or bathroom faucet is almost always a clogged aerator or a partially failed cartridge โ not low supply pressure. Stiff handles, dripping spouts, and leaks under the sink each trace to specific internal components. Our techs in Montclair know faucet valve anatomy across all the major brands and carry the parts to fix them.

Faucet repair looks simple until the wrong cartridge is installed, a seat-and-spring assembly is put in backwards, or a corroded packing nut strips during removal. Our techs know the specific disassembly sequence for the faucets they work on in Montclair, CA.
Ball faucets, cartridge faucets, ceramic disc faucets, and compression faucets all fail differently and require different repair approaches. A ball-type faucet drips from a worn ball, springs, seats, or O-rings โ all small parts that come in a manufacturer-specific repair kit. A cartridge faucet drip is almost always solved by cartridge replacement. Knowing which type you have before touching it determines whether the repair takes 30 minutes or 2 hours.
We identify the brand and model from the fixture, source the correct OEM or high-quality aftermarket cartridge, and install it correctly. Using the wrong cartridge on a pressure-balance shower valve doesn't just drip โ it can cause scalding or cold-water bypass.
Shower valves โ particularly pressure-balance and thermostatic mixing valves โ are more complex than a kitchen sink faucet and have safety implications if repaired incorrectly. We carry cartridges for the major pressure-balance valve brands common in Montclair, CA homes and understand the anti-scald setpoint calibration that should be verified after any shower valve cartridge replacement.
Not every under-sink leak is the faucet itself โ many are supply line connections, P-trap slip joints, garbage disposal collars, or drain body gaskets. Our techs trace the water source precisely before recommending a faucet repair or replacement.
Here's the full range of faucet repair work our techs handle in Montclair, CA โ by fixture type and by symptom.
Older kitchen faucets with two separate handles use compression valves โ each handle has a rubber seat washer that wears and needs periodic replacement. We stock washers and seat tools for these older designs, which are still common in Montclair, CA homes built before 1980.
Single-handle bathroom faucets use cartridge valves โ one cartridge controls both hot/cold mixing and volume. When the cartridge wears, the result is a drip that typically starts slowly and worsens over months. We identify the cartridge model by the faucet brand and replace it with the correct OEM cartridge.
Shower pressure-balance valves keep the water temperature stable when someone flushes a toilet or runs a dishwasher. When the cartridge wears, you lose that temperature compensation โ hot and cold water temperatures swing unpredictably during the shower. We replace pressure-balance cartridges for Moen, Delta, Kohler, and other common brands found in Montclair, CA homes.
Outdoor hose bibbs fail in two ways: a dripping spout (worn stem packing or seat washer) or a leak at the packing nut behind the handle (deteriorated packing material around the stem). Most hose bibb repairs involve replacing the seat washer and packing without removing the body from the wall.
Persistent low flow after aerator cleaning points to a partially failed cartridge that's not opening fully, or a kinked supply hose under the sink. We trace the restriction and resolve it.
When a faucet is discontinued (no available replacement cartridge), heavily corroded at the body, or simply past useful life, we replace the fixture. We supply faucets in the common hole configurations (single-hole, three-hole, widespread) and in finishes to match your existing hardware โ chrome, brushed nickel, oil-rubbed bronze.
Here's exactly how a Masters Plumbing Service faucet repair call runs in Montclair, CA.
If you know the brand โ Moen, Delta, Kohler, Price Pfister โ tell us. If not, the tech will identify it on-site from the valve body and handle design.
For many major-brand cartridges โ Moen 1225, Delta RP46074, Kohler GP30413 โ the part is on the truck and the repair proceeds immediately.
If the faucet body is corroded or the seat is damaged, we explain the repair complication and re-quote before proceeding.
After repair, we run the faucet through the full temperature range, check the spout, base, handle, and supply connections for any drip, and confirm the aerator flow is unrestricted. The repair is complete when we can demonstrate it's dry and flowing correctly.

Single-handle Moen bathroom faucet dripping at the spout. Tech pulled the cartridge โ an old 1200 design that was heavily scaled โ swapped in a new Moen cartridge, adjusted the flow limiter, and the faucet has been silent for three months. Clean work, fast, reasonably priced.
Had a hose bibb that dripped at the packing nut all summer. Tech replaced the packing material and seat washer in 20 minutes. Also told me the freeze-proof stem length was correct for my wall depth, which was reassuring heading into winter.
Low flow in the master bath โ I assumed the pressure regulator was failing. Tech cleaned the aerator (heavily scaled), and flow went from a trickle to full pressure immediately. 10-minute fix, saved me from chasing a pressure problem that didn't exist.
