Modern faucets use cartridges; older ones use washers. We identify the brand and series, source compatible parts, and test for drips and handle feel before we leave.
Corroded supply lines and loose compression fittings drip into cabinets long before you notice stains. We replace lines and valves when corrosion makes another tighten futile.
Pull-down sprayers, touchless sensors, and widespread lavatory sets need proper hole spacing and supply stops. We install and leak-test every connection.
Every job is completed by licensed plumbers with full liability coverage.
Dripping faucets, worn cartridges, and supply line leaks repaired or replaced.
We explain the problem and quote before work begins — no surprise charges.
Moen, Delta, Kohler, Pfister, and universal cartridges cover most San Mateo service calls without a second trip.
Bay Area mineral content wears cartridges faster. We recommend appropriate models when replacements make sense.
We replace deteriorated angle stops when we see corrosion ? cheap insurance against future cabinet damage.
Super quick response, able to fix all the issues they saw at a reasonable price after hours for emergency faucet and pipe replacement. Gave me constant updates and provided photo evidence for all issues they saw and recommended preemptive fixes that would’ve caused issues in the future. Super professional and was able to fix all issues in two hours.

Quick and responsible service. Don checked and repaired our leaky sink and water faucet adapter the same day that I called for the service. The work was professionally performed with proper cleanup afterward. I also like the fact that he wore shoe covers inside the house without the need for me to ask him to do so. Great work!

I’ve been using Don since his business began. Don always offers the best prices for all San Francisco draining needs. I’ve used him for faucet installations, garbage disposal, drain clogs, outdoor and indoor plumbing needs, plumbing leaks, sewer cleaning, among other services for my properties. My neighbors also raved about his coverage in the San Francisco bay area region for shower installation, water tank needs, drain cleaning, sink draining, etc. He far and away exceeds my expectations especially in the San Francisco Bay Area region where prices are exorbitant. With Don, you get bang for your buck for professional plumbing and drainage needs with free warranty for the first month! I’ll be using Don for years to come! Hey Don, time to start a loyalty program?!

Came home to no hot water. Asked neighbors who to call. ASAP was true to their name. Showed up almost immediately, diagnosed the failed hot water tank, and got a replacement installed very fast. Also fixed a flow issue we had. Good communication throughout the process, which I greatly appreciate.

I've been looking for a plumber for probably 4 years now. They either don't show or Pad the quote or double the estimate, or ask such a ridiculous price that I end up buying the equipment. And doing the job myself. I was so pleasantly surprised by ASAP plumbing!... the representation, the quick call back, the professionalit, the price, the promptness and the immediate response, everything everything was amazing. I already called them back to do another job.

Donald from ASAP Plumbing was super quick and responsive. Helped me out in both San Francisco and South San Francisco. On the first occasion, he was able to unclog the drain in no time! On the second occasion, he was able to push out the "thing" that was stuck in the pipes, saving me from having to potentially replace the toilet entirely!! Super professional and easy going. 100% recommend.

Had a leakage with shower head and found them on Thumbtack. They came out same day and fixed it the same day too! Explained the issue very well and offered multiple options for repair. Highly recommend

We had two leaky sinks in our house and called ASAP to fix the problem. Kong arrived and quickly assessed the situation. After discussion with both Kong and Donald, we concluded that the repair for the basement sink would not be necessary. Kong fixed the kitchen sink in a timely and professional manner. I would highly recommend ASAP for your plumbing needs. They provide fast, professional service at very reasonable rates. I also like how they provide a one year service warranty.

A steady drip from a kitchen or bathroom faucet wastes water and rots cabinets from the inside out. ASAP Plumbing Pros repairs cartridges, washers, and seals in San Mateo — and installs new faucets when corrosion or obsolete parts make repair impractical.
We carry common cartridges and supply lines for major brands. You get upfront pricing before we spread tools across your sink. Learn more at our faucet repair & replacement hub.
Pull-down sprayers, touchless models, and widespread lavatory sets need correct hole spacing and solid shutoff valves. We replace angle stops when corrosion makes future service risky.
Mineral buildup stiffens cartridges and clogs aerators. We clean or replace components and recommend fixtures that tolerate local water chemistry when you are ready to upgrade.
