Faucet Installation
Faucet projects fail at the compatibility check more often than at the wrench: the sink's hole pattern versus the new faucet's footprint, the counter's thickness versus the mounting hardware, the pull-down hose's need for clearance below, and the perennial ambush, supply stop valves that chose this exact moment to stop closing. The installation is an hour; the checking is why it stays an hour.
This page covers installing and replacing faucets across the house: kitchen, bath, bar, laundry. Replacement is installation plus the demolition of whatever corrosion built over the old flange. A faucet that merely drips or weakens deserves the repair page's diagnosis first, since cartridges cost less than fixtures.
How a Plumber Diagnoses the Problem
The compatibility checklist:
- Holes and footprint. One-hole, three-hole, widespread, wall-mount: the sink or counter's drilling decides what fits, and deck plates negotiate only some mismatches. Counting holes before buying is the cheapest advice in fixture plumbing.
- Deck thickness and access. Stone counters and farm sinks push mounting hardware to its limits, and the nut that secures everything lives in the least reachable place in the kitchen. It gets verified reachable before the old faucet leaves.
- The stops beneath. Supply valves that have not turned in a decade get tested first. A stop that will not close or weeps when disturbed joins the scope now, deliberately, rather than mid-job as a surprise.
- Connector reach and hose clearance. Supply lines must reach their stops without strain; pull-down faucets need under-sink space for the hose and its weight to travel. Garbage disposals and filters compete for exactly that space.
- Set, seal, prove. Mounted square, sealed at the deck, connections made to torque. Then both temperatures run, the aerator is checked for debris from the work, and the cabinet floor is inspected dry after a real soak test.
Service Details & What's Included
What shapes the visit:
- Replacement's hidden half. Removing a corroded old faucet is regularly harder than installing the new one. Seized nuts and mineral welds are where the time goes, and honest quotes say so.
- Stops and connectors, renewed by default. New faucet on old failing stops is a false economy. The visit prices their renewal upfront so the system under the sink matches the fixture on top of it.
- Touchless and accessory extras. Battery or powered faucets, soap dispensers, filtered-water taps: each adds a connection or a mounting hole to the plan, named in scope rather than discovered.
- When repair wins instead. A quality faucet with a worn cartridge repairs for a fraction of replacement. The repair page's math gets offered honestly before any fixture is sold.
Frequently Asked Questions
Can a new faucet use the existing supply lines?
Sometimes physically, rarely wisely. Connectors are inexpensive, age-hardened ones fail at the worst time, and the new faucet's connection type may differ anyway. Standard practice in the trade is fresh connectors and a tested stop valve, so everything under the sink starts the new faucet's life at zero.
Does the new faucet need the same hole configuration as the sink?
It needs a compatible one: matching is simplest, deck plates cover some downgrades from three holes to one, and going the other direction needs drillable material or a different choice. The hole count check happens before purchase. It is the difference between an install and a return trip.
Is faucet replacement different from faucet installation?
Replacement is installation preceded by an argument with the old hardware: seized mounting nuts, corroded connections and mineral buildup that resist removal. Same destination, extra chapter. New-construction and remodel installs skip the argument, which is why the two get quoted differently.
What if the shutoff valve under the sink leaks or won't close?
It gets replaced as part of the job. Working stops are the prerequisite for every future service on that fixture, and a valve that weeps when finally exercised has announced its retirement. Discovering this mid-swap is common, which is why testing the stops is step one, not step five.
Do touchless faucets complicate installation?
They add a power source (batteries or a plug) plus a control box and solenoid under the sink, all wanting dry, accessible placement. The plumbing is conventional; the extras claim cabinet real estate and a maintenance note. Troubleshooting their electronics later is manufacturer territory.
