Professional faucet installation covers removing the old faucet, cleaning the sink deck, mounting the new fixture, connecting hot and cold supply lines, and testing for leaks. We install all styles — single-handle, widespread, pull-down kitchen faucets, vessel sink faucets, and wall-mount units. Supply valve replacement is recommended if your shutoff valves are original gate valves or show signs of corrosion.

Sacramento's hard water (10-17 gpg) accelerates aerator clogging and cartridge wear. Consider faucets with ceramic disc valves and easy-clean aerators for longer life.

Fairfax is located in Marin County (North Bay). Bohemian small town in western Marin with hillside cottages and a creative community. The local utility provider is PG&E.

New Faucet Installation

Feed the faucet lines through the deck holes, secure the mounting hardware from below, and hand-tighten all connections. Install a deck plate if the new faucet has fewer holes than the sink.

Faucet Installation in Fairfax — FAQ

How long does a faucet installation take?+

A straightforward faucet swap takes 45-75 minutes. Older homes with corroded connections or non-standard plumbing may take up to 2 hours.

Should I replace shutoff valves when installing a new faucet?+

If your home has original multi-turn gate valves or the valves drip when closed, replacing them with 1/4-turn ball valves is strongly recommended. It adds about $50-$80 to the job.

Can I install a single-hole faucet on a 3-hole sink?+

Yes. A deck plate (escutcheon) covers the extra holes. Most new faucets include one, or we supply a matching plate.

What faucet brands hold up best with Sacramento hard water?+

Delta with Diamond Seal technology, Moen with Power Clean spray, and Kohler with ProMotion hoses all resist mineral buildup well in hard water areas.
