Kitchen faucet replacement is a fixture swap. The old faucet comes off the sink, the new one goes on, and it connects to the existing supply lines and shutoff valves under your cabinet. No wall gets opened and no new pipe gets run. In Philadelphia I handle this as part of my Plumbing Fixtures work, and the labor has a fixed price range. You’ll find it in the cost section below.
This page covers three things. First, what a kitchen faucet replacement costs in labor. Second, how the swap is done, step by step. Third, the exact point where it stops being a handyman job and becomes a licensed trade. If your faucet drips or leaks and may not need replacing at all, the next section sorts that out first.
Kitchen Sink Faucet Replacement or Repair: What Your Faucet Is Telling You
The symptom tells you which job you need: a repair, a leak diagnosis or a full kitchen sink faucet replacement.
A drip from the spout, or a handle or diverter that won’t switch to the sprayer, points to the inside of the faucet. A common cause is a worn cartridge or seal, and that is a repair.
Water around the base or inside the cabinet is a different problem. It can come from a supply connector, a loose nut, the faucet body or the drain. The source has to be found before anyone decides to replace a kitchen sink faucet.
An old, corroded faucet, or one you simply don’t want anymore, is a straight replacement.
| Symptom | What it usually means | Repair or replacement |
|---|---|---|
| Spout drips, or the handle or diverter won’t switch | Worn cartridge, seal or valve inside the faucet | Usually a repair |
| Water at the faucet base or inside the cabinet | Supply connector, mounting nut, faucet body or drain | Find the source first, then decide |
| Corroded, worn out or unwanted faucet | The fixture has reached the end of its life | Replacement |
Repair is worth it when the faucet body is sound and parts are still available. Kitchen sink faucets replacement makes more sense in three cases:
- the body is corroded;
- the model can’t be identified;
- you want a different faucet anyway.
Labor for each case is listed in the cost section.
Who Should Replace a Kitchen Faucet: You, a Handyman, or a Licensed Trade
Who should replace a kitchen faucet depends on what’s under your sink, not on the faucet itself.
Doing it yourself
If you’re asking “how do I replace a kitchen faucet,” the honest answer is that a lot of homeowners change a kitchen faucet themselves, and that’s fine. It’s a reasonable DIY job when three things are true:
- both shutoff valves under the sink close and actually hold;
- there’s enough room in the cabinet to get your arms and a wrench up behind the sink;
- you have the tools and the patience for nuts that may not want to come loose.
If the valves don’t hold, stop there. Don’t push through.
Calling a handyman
A handyman fits when the faucet is bought and the job is a swap on the existing supply lines and shutoff valves. That covers most cases of replacing kitchen sink faucets: old fixture out, new fixture in, connections checked, cabinet dry.
When it’s a licensed trade
The work becomes a licensed trade as soon as it goes into the wall, the riser or the drain line, or involves gas. That is a licensed trade, not this job.
This is how I work: if I see the job needs to go into the wiring or the pipes, I say so honestly and send you to the right trade. I don’t try to wriggle out of it. You hear about it before anything gets taken apart, not halfway through.
The section below is for people who would rather not lie under the sink at all.
A Handyman for Seniors and Anyone Who Would Rather Not Work Under the Sink
A handyman for seniors is simply someone who does the awkward part, lying on your back inside a cabinet with a wrench, so you don’t have to. The same goes for anyone else who would rather skip it.
For older homeowners and their families, the visit is predictable. One person comes. Before anything is touched, I explain what will be done to the faucet and the connections. When the kitchen faucet replacement is finished, I clean up before I leave — that’s part of the job, not a favor.
How I Change a Kitchen Faucet, Step by Step
Changing a kitchen faucet is a fixed sequence: shut off the water, remove the old fixture, prepare the sink deck, mount the new faucet, reconnect and test. This is how to replace a kitchen faucet the way I do it, and it’s the same answer if you’re working out how to change faucet in kitchen yourself.
- Clear the cabinet. Everything under the sink comes out. A bucket and a towel go in, because there is always some water left in the lines.
- Shut off and test. Close both shutoff valves, then open the faucet. If water still runs, the valves don’t hold, and the job stops until that’s resolved.
- Disconnect the supply connectors. Unscrew them from the valves and let the water drain into the bucket.
- Remove the mounting nuts. They sit up behind the sink bowl, where there’s little room to work. A basin wrench reaches them when a regular wrench can’t. Then lift the old faucet out from above.
- Clean the sink deck. Old sealant, mineral deposits and grime come off, so the new gasket or deck plate sits flat. Skipping this is a common reason for a leak at the base later.
- Set the new faucet. Seat the gasket or deck plate and feed the hoses down through the hole. On a single-hole, three-hole or sprayer-hole sink, the hole layout decides which parts you need.
- Tighten from below. Make it snug and even, but don’t overtighten. Too much force can crack a plastic mount or distort the gasket.
- Connect to the existing valves. Faucets and toilets are swapped on the existing supply lines. On a pull-down model, clip the hose weight on so the spray head retracts.
- Test. Remove the aerator and turn the water on slowly. Let it run so debris flushes out instead of clogging the aerator. Then wipe every connection with a dry paper towel. Any damp spot shows on paper long before it shows as a drip.
The drain under the sink is not part of this job. The swap itself is normally a short one. How long it takes depends mostly on the condition of the old nuts and the shutoff valves.
What Gets Tricky When Changing Out a Kitchen Faucet
The hard part of changing out a kitchen faucet is almost never the new faucet. It’s what the old installation left behind. Each common problem below is handled within the visible plumbing, or else it’s where the job stops.
- Seized mounting nuts. Corrosion can lock old nuts in place. A basin wrench, patience and careful force usually free them. The goal is to free the nut without cracking the sink.
- Shutoff valves that won’t close fully. If a valve doesn’t hold, the faucet can’t be changed safely. If fixing it means going into the pipe inside the wall, that is a licensed trade, not mine.
- Hole count mismatch. A three-hole sink with a new single-hole faucet usually takes a deck plate. A spare hole can hold a sprayer or a soap dispenser. Check this before you buy.
- A tight cabinet. Disposals, filters and stored pipes crowd the space. They slow things down but rarely block the job.
- A dishwasher line on the same valve. I don’t install or repair dishwashers. If its line shares a valve with the faucet, you’ll know up front so you can plan that part separately.
All of this gets checked at the photo stage, before I arrive, so none of it comes as a surprise on the day you change out the kitchen faucet.
Delta or Any Other Brand: You Pick the Faucet
You choose and buy the faucet yourself. It can be a Delta kitchen faucet or any other brand. That way you get exactly the finish, spout and features you want, not whatever was on my truck. The price is for the work.
Before buying, check two things: the number of holes in your sink deck and the type of connection the faucet uses. For a Delta kitchen faucet replacement in Philadelphia, or any brand, a photo of your sink from above answers the hole question quickly.
If you’d rather not shop, I’ll buy it on your receipt. It costs the receipt price plus a small purchasing markup, shown as a separate line on the estimate.
Where My Job Ends: Pipes in the Wall, Risers, Drains and Gas
My part of a kitchen faucet replacement is the fixture itself and the visible connections under the sink. Everything beyond that belongs to someone else.
| This job | A licensed trade |
|---|---|
| The faucet on the sink deck | Pipes inside the wall |
| Supply connectors to the existing valves | Risers |
| Visible connections under the sink | Drain lines and sewer |
| Checking the cabinet for leaks after the swap | Gas of any kind |
Pipes in the wall, risers, drains and sewer are a licensed trade, not mine. I don’t work with gas at all.
Some leaks come from inside the wall rather than the visible plumbing. Some jobs turn out to need the wall opened to reach the pipe. In either case, I say so straight away and refer you to a licensed trade. I don’t try to wriggle out of it or improvise around it.
Knowing this line in advance saves you a visit that ends with “this isn’t my job.” That’s another reason the photo comes first.
Kitchen Faucet Replacement Cost in Philadelphia (Labor Only)
Kitchen faucet replacement cost in Philadelphia, for labor on the existing supply lines, is a fixed range. The faucet itself is separate.
| Job | Labor |
|---|---|
| Faucet replacement | $120–180 |
| Faucet repair (drip or a valve that will not switch) | $100–150 |
| Leak under the sink, visible plumbing | $110–170 |
Prices are for labor — materials and hardware are separate.
Where your job lands inside the range depends on what’s under your sink:
- the condition of the old nuts and shutoff valves;
- how much room there is in the cabinet;
- whether there’s an extra sprayer or soap dispenser hole to deal with.
So when someone asks “how much should I pay to have a kitchen faucet replaced?”, I need to see it first. On the phone I give only the range.
Send a photo of the job and the price comes back the same day. Here’s how to take the photo.
A fixed price in writing before I start. Once the work begins, I don’t change it.
The full list is on the pricing page.
Bathroom Faucet Replacement: Same Work, Same Price Line
A bathroom faucet replacement is done the same way, on the existing supply lines and shutoff valves. It falls under the same faucet replacement line in the price table above.
The difference is in the details. On a bathroom sink, the pop-up drain usually comes with the faucet, so it gets installed as part of the swap. Anything below the drain is a different job.
More on this kind of work is on the Plumbing Fixtures page.
What I Need From You and How the Visit Goes
To replace a sink faucet in your kitchen, I need three things from you before the visit:
- Two photos: one of the faucet and sink deck from above, and one of the open cabinet from below with the shutoff valves and connections clearly visible.
- The faucet already bought, or an agreement that I’ll buy it on your receipt.
- A cleared-out cabinet, so work can start right away.
Then the visit is simple. I come myself and do the job from start to finish. I run the water, check every connection for drips, and clean up before I leave. If something needs a second look later, the same person who did it comes back.
Book a Kitchen Faucet Replacement

Frequently Asked Questions
-
How much should I pay to have a kitchen faucet replaced?
Labor for a faucet replacement on the existing supply lines is $120–180, and the faucet itself is separate. Where your job lands in that range depends on the old nuts, the shutoff valves and access inside the cabinet. The exact price comes from a photo, and it doesn’t change once the work starts.
-
How do I replace a kitchen faucet myself?
Shut off both valves and check they hold by opening the faucet. Disconnect the supply connectors, remove the mounting nuts and clean the sink deck. Set the new faucet and gasket, then connect it to the existing valves. Turn the water on slowly and wipe each joint with a dry paper towel. If the valves don’t hold, stop.
-
Can you install a Delta kitchen faucet I already bought?
Yes. You choose and buy the faucet, Delta or any other brand, and I install it on the existing supply lines. Before buying, check the number of holes in your sink and the connection type.
-
My faucet drips. Repair it or replace it?
A drip from the spout, or a valve that won’t switch, is often a worn cartridge or seal. Repair labor for that is $100–150. If the body is corroded, parts aren’t available, or you want a different faucet anyway, replacing it makes more sense. A photo of the faucet, plus the model if you know it, usually settles the question.
-
The shutoff valves under my sink won’t close. Can you still change the faucet?
That’s exactly what I check at the photo stage, so you know before I arrive. If the fix means going into the pipe inside the wall, that is a licensed trade, not my job. I’ll tell you so honestly instead of trying to work around it, and you can plan the next step from there.
-
There’s water inside the sink cabinet. Is it the faucet or a pipe?
It could be a supply connector, the faucet base or the drain, so the source gets found first. Labor for a leak under the sink in the visible plumbing is $110–170. If the water comes from inside the wall or from a riser, that is a licensed trade, not this job.
-
My new faucet has one hole and my sink has three. Will it work?
Usually, yes. Most single-hole faucets come with a deck plate that covers the extra holes. A spare hole can also take a soap dispenser or a separate sprayer. Check this before buying, and send a photo of the sink deck from above so the fit is confirmed before the visit.
-
Will you reconnect my dishwasher when you change the faucet?
No. I don’t install or repair dishwashers. If the dishwasher line shares a valve with the faucet, I tell you before the work starts. That way there’s no surprise on the day, and you can arrange the dishwasher part separately with whoever handles that appliance.
-
Is a bathroom faucet replacement priced the same as a kitchen one?
Yes. It falls under the same faucet replacement line in the price list and is swapped on the existing supply lines. The difference is in the details: on a bathroom sink, the pop-up drain usually comes with the faucet and goes in as part of the swap. Anything below the drain is a different job.
