- Identify the faucet type first: compression, cartridge, ball or ceramic disc; each fails in a different part.
- Always shut off the water and plug the drain; a dropped screw in a Brooklyn pre-war drain is a bad afternoon.
- Most drips come from worn washers, O-rings or cartridges that cost little to replace.
- If shutoff valves are seized, pipes are corroded or the leak is below the sink, stop and call a licensed plumber.
- A faucet that keeps failing in an old kitchen may point to a bigger fixture, pipe or layout upgrade.
Drip. Drip. Drip. In a quiet brownstone at night, a leaking kitchen faucet is the loudest thing in the house. It also wastes water. A commonly cited figure puts a faucet dripping once per second at more than 3,000 gallons a year, and in a city where many buildings bill by usage, that adds up.
The good news is that most kitchen faucet leaks are small mechanical failures. This guide shows how to identify the type you own, how to fix it in ten steps, how to know when a Brooklyn pre-war quirk means it is time to stop, and when a new faucet belongs inside a bigger kitchen plan. It is current as of October 2026.
1. What a Drip Actually Costs
A drip costs more than the water. It stains the sink, corrodes the finish, and if the leak runs below the sink it rots the cabinet base and feeds mold. A small leak ignored for months can turn a ten-minute fix into a cabinet replacement.
In Brooklyn, add three local factors. Pre-war plumbing may have older shutoff valves that no longer seal. Brownstone kitchens often have tight sink bases, so small leaks go unseen. And co-op rules can limit who is allowed to touch the plumbing, which matters before you start. Reading those rules first saves problems later.
2. Identify Your Faucet Type
The repair depends on how your faucet works. Look at the handles and spout, then check under the handle cap.
| Type | How to recognize it | Common drip cause |
|---|---|---|
| Compression | Two handles that you screw tight to stop the water | Worn rubber washer or damaged seat |
| Cartridge | One or two handles, smooth motion | Worn cartridge or O-rings |
| Ball | Single handle on a rounded cap | Worn seats, springs or O-rings |
| Ceramic disc | Single handle, smooth, modern feel | Worn disc seals or cracked discs |
Older Brooklyn kitchens, especially in pre-war buildings and wood-frame houses, often have compression faucets. Renovated kitchens usually have cartridge or ceramic disc types. Search the brand and model stamped on the faucet body or the bottom of the handle for the right parts.
3. Tools and Parts
Gather everything before you start.
- Adjustable wrench and basin wrench
- Screwdrivers, flat and Phillips
- Allen keys
- Penetrating oil for stuck parts
- Replacement parts matched to your faucet: washers, O-rings, cartridge or disc seals
- Plumber's grease
- White vinegar and an old toothbrush for scale
- Rag or towel and a bowl for screws
- Flashlight
Take a photo of the faucet as you remove each part. That is the cheapest insurance you can buy.
4. The 10-Step Repair
These steps cover most kitchen faucets. Details vary by brand, so follow the manufacturer's instructions where they differ.
- Identify your faucet type. Use the table above.
- Shut off the water. Close the hot and cold shutoff valves under the sink. If a valve will not turn or drips when closed, stop here and call a plumber. Do not force an old valve.
- Plug the drain. A towel or stopper keeps small parts from vanishing.
- Open the faucet. Turn it on to release pressure and confirm the water is off.
- Remove the handle. Pry off the decorative cap, remove the screw and lift the handle.
- Remove the trim and cap. Unscrew the retaining nut or collar to expose the stem or cartridge.
- Take out the stem or cartridge. Pull straight out, noting orientation. For compression stems, unscrew with a wrench.
- Inspect and clean. Check washers, O-rings and the valve seat. Scrub scale with vinegar. A pitted seat on a compression faucet may need a seat dresser tool.
- Install matching parts. Replace the washer, O-rings or the whole cartridge, and lightly coat with plumber's grease.
- Reassemble and test. Put it back in reverse order, open the faucet, turn the supply valves on slowly and check for leaks at the handle, spout and under the sink.
Let the faucet run for a minute to clear air. Dry the area with a towel and look again after an hour.
5. Fixes by Faucet Type
Compression faucets
The rubber washer at the bottom of the stem presses on the seat. Over time the washer hardens or the seat pits. Replace the washer with an identical size and, if the seat is rough, resurface it. If water leaks around the handle instead of the spout, replace the packing washer or O-ring.
Cartridge faucets
Pull the retaining clip, lift out the cartridge and replace it with an identical one. If you replace only the O-rings and the leak continues, the cartridge itself has worn.
Ball faucets
These have many small parts. Replacement kits are available by brand and include springs, seats, O-rings and the cam. Buy the full kit instead of picking pieces.
Ceramic disc faucets
The seals under the disc cartridge are the weak spot. Replace the seals and clean mineral deposits. If a disc is cracked, replace the whole cartridge.
Protect the cabinet while you work
Lay a towel or small tray in the sink base before you open anything, and keep a bucket handy for trapped water in the lines. Wipe the base dry when you finish and check it again the next morning with a dry paper towel pressed against the joints. A towel that comes away damp means a slow leak you have not found yet, and it is far cheaper to chase it now than after the cabinet floor swells. In tight Brooklyn sink bases, a headlamp is worth more than any tool in the bag.
6. Troubleshooting Stubborn Leaks
Not every fix goes smoothly.
- Still dripping after new parts: The seat or valve body may be damaged. Replace the faucet.
- Handle leaks: O-rings or packing are worn, or the retaining nut is loose.
- Base leaks: The gasket under the faucet is failing, or mounting nuts are loose.
- Weak pressure after repair: Aerator debris or a misaligned cartridge.
- Hot water only drips: Check the hot-side supply valve and seat.
- Hammering sounds: Loose pipes or worn washers; a plumber should check supply lines.
If scale is heavy, soak removable parts in white vinegar for an hour. Brooklyn tap water varies, but mineral buildup in older fixtures is common.
7. When to Stop and Call a Licensed Plumber
Know your limits. Stop and call a pro if:
- The shutoff valves will not close fully or weep when turned.
- Corrosion has fused parts together.
- You see water below the sink, on the wall or on the ceiling beneath you.
- The faucet body is cracked or the deck is loose.
- Supply lines are old braided or rigid pipe with visible green corrosion.
- You live in a co-op or condo where only licensed trades may touch plumbing.
- You are moving a sink, adding a pot filler or changing pipe runs.
New York restricts most plumbing work to licensed plumbers, and filings may be required for anything beyond minor repairs. See the NYC Department of Buildings permit overview and our permit checker for a quick read on your situation. Your alteration agreement or house rules may add requirements, so read them first.
8. DIY Versus Professional: What Each Route Costs
Costs vary by building and scope. For a faucet repair, the DIY route is mostly your time and a few parts. A professional route adds a visit charge and labor but brings a warranty on the work and access to tools and experience. When you compare, add up time, repeat visits and the cost of a mistake.
| Route | What you pay for | Main risk |
|---|---|---|
| DIY repair | Parts, tools, your time | Seized valves, hidden corrosion, a second trip to the store |
| Licensed plumber repair | Visit, labor, parts | Scheduling; ask for the price in writing |
| New faucet installed | Faucet, labor, possibly supply lines | Mismatched sink holes, old valves |
| Full kitchen remodel | Cabinets, counters, plumbing, finishes | Budget and approvals; typical 2026 planning range roughly $25,000 to $85,000 or more |

9. Why a Licensed Pro Beats Another Patch
A faucet is a small part of a kitchen, but the leak often reveals larger problems. Soft cabinet bases, stained flooring beneath the sink, corroded supply lines and failing shutoff valves are common in older Brooklyn kitchens. Patch each one on its own and you may pay three visits and still have a leak.
N.Y. Renovation Services approaches the kitchen as a system. Our in-house team looks at plumbing, cabinets, flooring and finishes together, and coordinates licensed plumbers and electricians so every trade works in sequence. We handle permits and co-op or condo board paperwork when a project needs them, schedule around freight elevators and building hours, and test older buildings for hazardous materials before demolition. Pricing is itemized and transparent, so you see plumbing, cabinets, counters, tile and paint as separate lines. Five percent of your total project cost goes to a nonprofit of your choice.
You do not need a gut renovation to benefit. Some clients start with the leak, then add cabinet painting, a new backsplash or new floors while the area is open. Painting kitchen cabinets typically runs about $3,500 to $9,000 in 2026 planning ranges, and our guide to painting kitchen cabinets in a Brooklyn apartment explains the process. If layout is the real issue, read Architect's Top 10 Kitchen Design Mistakes before you commit.
What does a visit look like? We open the sink base, check shutoff valves and supply lines, probe the cabinet floor for softness and look at the flooring edge for staining. You get a plain-language list of what is fine, what needs a licensed plumber and what we would replace now while the area is open. If the answer is "just a cartridge," we say so. If the cabinet base is rotting or the subfloor is wet, we price the repair and rebuild in separate lines, including flooring and paint, and you can request an itemized quote before deciding anything. Because we also handle interior painting and flooring, a small repair does not leave you with a patched wall and a mismatched floor.

10. Prevent the Next Drip
- Replace rubber washers and cartridges every few years, or at the first sign of dripping.
- Clean aerators every few months to prevent scale buildup.
- Exercise shutoff valves twice a year so they do not seize.
- Wipe the sink area and check under the sink monthly.
- Do not over-tighten handles; compression washers wear faster.
- Keep a spare cartridge or kit for your model.

11. Neighborhoods and ZIP Codes We Serve
Brooklyn kitchens vary with the building. Here is what we see.
- Ditmas Park (ZIP 11226): Detached Victorian wood-frame houses, some within LPC districts. Old supply lines, cast-iron drains and sink bases that have settled are typical, and exterior changes may need Landmarks review.
- Boerum Hill (ZIPs 11201, 11217): Brownstones and row houses in the LPC Boerum Hill Historic District. Narrow kitchens with older risers, and plaster walls behind sink bases.
- Windsor Terrace (ZIP 11218): Wood-frame row houses and small co-ops. Basement-level shutoffs and shared riser rules affect repairs.
- Bensonhurst (ZIPs 11204, 11214): Brick row houses, attached homes and multifamily buildings, often with multiple kitchens sharing pipes.
- Dyker Heights (ZIP 11228): Detached and semi-detached brick homes on large lots, with separate basement kitchens and multiple fixtures.
- Sheepshead Bay (ZIP 11235): Waterfront homes, co-ops and flood-zone considerations, which can affect basement plumbing and fixture selection.
