Faucet Repair & Installation
Faucet Repair in Marin, Sonoma & Napa County
Your kitchen and bathroom faucets are some of the hardest-working fixtures in your home, used countless times each day for everything from washing hands and dishes to cooking and cleaning. With constant use, even the most dependable faucets can begin to show signs of wear, dripping, leaking, making odd noises, or restricting water flow.
While a faulty faucet may still appear to function, if it is operating inefficiently, it can lead to wasted water, higher utility bills, and potential damage to surrounding fixtures or cabinetry. Timely faucet repairs aren’t just a matter of convenience, they’re essential for water conservation and cost savings.
Ongaro & Sons provides professional faucet repair services throughout Marin, Sonoma, and Napa counties as well as surrounding regions of the North Bay. Whether you’re dealing with a slow leak or reduced water pressure, our skilled plumbers can quickly diagnose the issue and restore full functionality.
Over time, faucets experience wear and tear that can lead to a range of issues. While faucet repairs may seem deceptively easy, even if you are armed with a few how-to plumbing books, wrenches, screwdrivers, pliers, and washers, correctly diagnosing the problem and fixing it can be daunting.
Our licensed plumbers are experienced in working with all faucet styles, makes, and models. We are always prepared to tackle whatever the job entails. We work efficiently and complete the job as quickly as possible.
Common Faucet Issues We Repair in Marin, Sonoma & Napa County
Fixing an easily corrected leak in your household can save you up to 10 percent on your water bill. We address the most common faucet problems, including:
Strange Noises
Whistling or screeching sounds when using your faucet could be a sign of air in the pipes, water pressure issues, or faulty parts.
Water Leaks From the Spout or Base
Persistent dripping or pooling around the base often signals worn washers, gaskets, or internal seals.
Low Water Pressure
If your faucet has weak water flow, it could be due to mineral buildup, a clogged aerator, or a deeper plumbing issue.
Visible Corrosion or Mineral Buildup
Rust, discoloration, or white deposits may indicate aging materials and hard water damage.
Loose or Noisy Handle
Squeaking, sticking, or wobbly handles are often caused by worn internal components.
Clogged or Malfunctioning Sprayer
Side sprayers or pull-out faucets that sputter or stop working may be clogged with debris or mineral buildup.

Why Ongaro & Sons for Faucet Repair
Small job, and still worth a licensed plumber when the shut-off is seized.
Schedule Service →Repair weighed against replacement on parts
Cartridges for many quality faucets are available for decades. For others the fitting is disposable and repair is false economy.
Shut-off valves checked and replaced if seized
The valve that will not close is the reason a small repair becomes a call-out with the main off.
Water quality noted as a cause
Repeated cartridge failure and aerator blockage usually point at sediment or hardness worth addressing.
Supply lines replaced where they are aged
Cheap to do while access is open, expensive when they let go.
Small job, same licensed plumber
A tap repair is carried out by the same C-36 licensed company that would handle your service line, not by a different tier of labour.
