Replacing Faucets and Fixtures: A Homeowner Guide

A faucet swap is a one-hour job attached to a lottery ticket called the shutoff valves. The faucet part is straightforward: disconnect, drop the old one out, seat the new one, connect, test. The adventure, when there is one, lives under the sink, where valves that have not moved since the Clinton administration decide whether they still know how to close. This guide covers choosing a fixture that fits, what the job actually involves, the local hard-water context, and honest Treasure Valley cost ranges.

A drip is a cartridge; replacement is a choice about fit, finish, and future. Nearly all modern faucets seal with a replaceable cartridge, and a dripping spout or a handle that seeps usually means that $10 to $40 part, not a new faucet. Major-brand cartridges are stocked locally and some carry generous replacement policies.

Replacement wins in four situations: the body or finish is corroded or pitted, the brand is unknown and parts are unfindable, the same faucet has needed repair repeatedly, or you simply want something better. What you should not do is pay repair labor twice on a faucet with no future. If the first cartridge does not cure it, the second visit should install a new unit.

Fit is decided by the holes already in your sink, so start under the counter, not at the store. Count the holes and measure the spacing between outer holes, center to center. Bathrooms are usually 4-inch centerset or 8-inch widespread. Kitchens run single-hole or three to four holes, with sprayers and soap dispensers occupying the extras. A single-handle faucet with a deck plate covers an abandoned three-hole layout gracefully; the reverse conversion does not exist without a new sink.

On quality, the practical markers are a solid brass body, ceramic disc cartridge, and a brand whose parts your local supply house stocks. Finish matters more here than in most markets: Treasure Valley water is hard, and thin budget finishes spot and pit quickly under our mineral load. Mid-range and up survives; the $39 special often does not.

The sequence is short; the constraints are access and corrosion. Water off at the angle stops, lines disconnected, mounting nuts freed, old faucet out, deck cleaned of old putty and scale, new faucet seated and sealed, new supply lines connected, aerator flushed, and everything watched under pressure for ten minutes. Kitchen faucets add a sprayer hose and weight; bathroom widespreads add linkage between three pieces.

Two details separate tidy work from callbacks. First, new supply lines every time; reusing ten-year-old braided lines to save $12 is how cabinets get flooded. Second, a real leak check under full pressure, hot and cold, with a dry paper towel on every joint, before the tools leave the house.

In Boise-area homes from the 1990s and earlier, the valves are the job. Multi-turn stop valves seize in place after decades idle. Best case, they close and reopen and merely weep a little until snugged. Worst case, the stem breaks or the valve will not shut the water at all, and the swap now includes valve replacement, done with the house main off.

This is not a reason to fear the job; it is a reason to plan it. A pro tests the valves first, knows where your main shutoff is before touching anything, and carries quarter-turn replacement valves on the truck so the discovery costs thirty minutes instead of a second visit. If your valves are original and crusty, replacing them during the faucet swap is the cheapest moment you will ever get, and it is standard scope for minor plumbing repairs.

The same visit handles most of what screws, seals, or plugs in. Showerheads and handheld kits are minutes each. Garbage disposal swaps are routine when replacing like for like. Toilet fill valves and flappers pair naturally with sink work, covered in fixing common toilet problems. On the electrical side, light fixtures, ceiling fans on fan-rated boxes, and matching switch and outlet replacements are standard minor electrical scope, while anything involving new circuits or the panel goes to a licensed electrician.

Towel bars, mirrors, and bath hardware round out the list under mounting and assembly. The pattern is the point: one visit, several small upgrades, one trip charge, as laid out in what small home repairs cost in Boise.

Local water is hard enough to be a design constraint. Scale narrows aerators, stiffens cartridges, and spots finishes across Ada and Canyon County. Three habits extend everything: unscrew and vinegar-soak aerators and showerheads once or twice a year, wipe chrome dry in the splash zone rather than letting drops etch, and choose quality finishes when replacing, because they carry the mineral abuse far better.

When a two-year-old faucet already runs weak, the aerator screen is the first suspect and the ten-second fix. When every fixture in the house scales fast, a softener conversation is worth having with a plumbing contractor; installing one is beyond handyman scope, but living better with hard water is mostly maintenance.

Honest split: a bathroom faucet with healthy valves and room to work is a reasonable DIY afternoon. A basin wrench, patience, and the manual get it done. Book a pro when the valves are original, when the old mounting nuts are corroded overhead in a cramped cabinet, when the job is a widespread or wall-mount faucet, or when you want the disposal, showerhead, and two light fixtures done in the same trip.

Labor for a supplied faucet runs $130 to $300 locally, and the quote should say what it assumes about the valves, exactly the kind of stated assumption described in questions to ask a handyman.
