What a faucet swap actually involves

A like-for-like faucet swap is one of the few plumbing jobs worth trying yourself. The fixture usually costs more than the labor, and the work is mostly patience in a cramped cupboard.
The part that catches people out
The angle stops under the sink are the problem, not the faucet. They sit untouched for years, and turning one can crack the packing or snap the stem. Test both before you buy anything — if either weeps or won’t close, that’s a separate repair and the job has changed.
When to hand it over
Call us if the supply lines are corroded, if the sink is stone or undermounted, or if you’re changing the hole count. Those turn a one-hour swap into a fixture and countertop job, and it’s cheaper to start there than to finish there.
