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 Poolesville 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 Poolesville, MD.
Ceramic disc faucets from brands like Moen's newer series, American Standard, and European brands use a pair of ceramic discs that rarely fail but can crack from thermal shock (sudden cold water on a hot disc). Our techs carry common disc cartridge replacements for major brands.
Moen, Delta, Kohler, Price Pfister, American Standard, Grohe, Hansgrohe โ each brand uses proprietary cartridge and valve designs that are not interchangeable. Moen uses their own 1200 and 1225 cartridge system; Delta uses ball valves in older fixtures and cartridges in newer ones; Kohler uses Rite-Temp pressure-balance cartridges in shower valves.
Thermostatic shower valves (separate volume and temperature controls) are premium fixtures found in master baths where comfort and safety depend on correct cartridge specification. We don't substitute cheaper cartridges on thermostatic valves.
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.
Most faucet repairs complete in a single visit with parts on the truck.
Kitchen faucet issues typically present as: a dripping spout (worn cartridge or ball assembly), a leak at the base (failed O-ring at the faucet body), stiff or jerky handle movement (mineral deposits or corroded cartridge tracks), or reduced flow (clogged aerator or partially closed supply valve). We diagnose the cause, repair the specific component, and test for full leak-free operation.
Two-handle bathroom faucets (separate hot and cold) are often compression or ceramic disc designs. A drip from a two-handle set almost always comes from one side only โ telling us which handle's valve needs attention.
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 Poolesville, MD 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.
Reduced flow at a kitchen or bathroom faucet is almost always a clogged aerator โ the small screen-and-flow-restrictor assembly at the tip of the spout. Mineral scale from hard water accumulates in the aerator mesh over time, progressively reducing flow to a trickle. Aerator cleaning or replacement restores full rated flow in minutes.
We handle the full installation: shut the supply, disconnect the old faucet, inspect the supply lines and angle stop valves, install the new faucet, connect supply, adjust the aerator, and verify drip-free operation before leaving.
We identify the valve type before ordering or installing any part. The right cartridge for your faucet brand is what produces a lasting result โ not a generic part that fits loosely.
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.
The tech identifies the faucet's valve type (ball, cartridge, ceramic disc, or compression), locates the specific cartridge or repair kit number for that model, and checks whether the required part is on the truck or needs to be sourced.
If the faucet body is corroded or the seat is damaged, we explain the repair complication and re-quote before proceeding.
We also confirm the angle stop valves under the sink operate โ a seized stop valve that can't shut off in a future emergency is a problem worth noting while we're already under the cabinet.

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.
My shower temperature was impossible to control โ any toilet flush or washing machine cycle would cause a cold spike mid-shower. Masters Plumbing Service replaced the pressure-balance cartridge in the Kohler valve, set the anti-scald stop at 120ยฐF, and tested temperature stability by running the toilet while the shower ran. The swing went from 15+ degrees to less than 2. That's how a pressure-balance valve is supposed to work.
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.
