What sink types do we repair in NYC?
We repair every sink type across all five NYC boroughs — kitchen and bathroom, all styles, all materials, and every configuration. From a Brooklyn brownstone farmhouse sink to a Manhattan high-rise vessel sink, we handle it.
Kitchen and bathroom sink repair in all 5 boroughs
- Kitchen sinks: Undermount, drop-in, farmhouse (apron-front), bar, and utility sinks — in stainless steel, porcelain, composite granite, and fireclay — across Manhattan, Brooklyn, Queens, Bronx, and Staten Island.
- Bathroom sinks: Pedestal, vanity top, wall-mount, vessel, and undermount sinks in vitreous china, porcelain, glass, and stone — including compact sizes for NYC co-op powder rooms.
- Faucet and drain configurations: Single-handle, two-handle, pull-down, touchless, widespread, and centerset faucets paired with pop-up drains, grid strainers, basket strainers, or lift-rod assemblies.
- Pre-war building considerations: Many NYC pre-war buildings have cast-iron drain pipes that require special handling during sink repair to avoid cracking the old fittings — we treat them accordingly.
- All five boroughs: We dispatch to Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — sink repair NYC coverage that includes every neighborhood from Riverdale to Far Rockaway.
Faucet types and drain styles we service
- Faucet variety: We work with single-handle, two-handle, pull-down, touchless, widespread, and centerset faucets from all major brands — Moen, Kohler, Delta, American Standard, TOTO, Grohe, Pfister, Hansgrohe, and Brizo.
- Drain types: Pop-up drains with lift rods, grid strainers for kitchen sinks, basket strainers with stoppers, and toe-touch drains — each requiring different cartridge and seal configurations.
- Touchless faucet issue: Touchless faucets in NYC kitchens often fail because of hard water mineral buildup on the sensor lens — a simple cleaning can restore function without a replacement.
What causes a sink to leak under the cabinet?
Under-sink leaks usually trace back to a handful of common failure points — loose connections, cracked supply lines, or worn seals — and catching the source early prevents serious water damage.
Common causes of under-sink leaks
- Loose P-trap connection: We see this in roughly 80% of under-sink leak calls — the slip nuts work loose from thermal cycling or bumping the pipe, and a quick hand-tighten or new washer stops it.
- Cracked braided steel supply line: The steel jacket hides corrosion at the ferrule crimp; a pinhole leak can turn into a burst in minutes — replace any line older than 10 years during leaking sink repair.
- Failed faucet base seal: The O-ring or gasket under the faucet body dries out and cracks, letting water run down the shank and pool under the cabinet — usually requires a cartridge or base-plate replacement.
- Shut-off valve stem leak: The packing nut around the valve stem loosens over time; a quarter turn with a wrench stops the drip, but a seized or cracked valve body needs replacement.
- Drain flange leak: Plumber’s putty under the sink strainer dries out after 5–8 years — water seeps past the flange and drips onto the cabinet floor; removing and re-bedding the flange with fresh putty solves it.
If you see water pooling under the cabinet, turn off the shut-off valves immediately — a burst supply line can release 2–3 gallons per minute and cause extensive water damage.
How we diagnose and fix under-sink leaks
We start by running water and inspecting every connection — P-trap nuts, supply line fittings, faucet base, and shut-off valve packing — then tighten, replace washers, or swap out damaged parts as needed. On a typical call, the culprit is obvious within two minutes: a loose nut that spins freely, a supply line with visible rust at the crimp, or a puddle directly under the faucet shank. We carry an inventory of standard parts — brass compression ferrules, 3/8-inch braided supply lines in 12- and 20-inch lengths, PVC P-trap assemblies, and universal faucet base gaskets — so most fixes happen in a single trip. In NYC high-rises, the water pressure can reach 80 PSI, which accelerates wear on compression fittings and braided lines — we install pressure-reducing valves when we see repeated fitting failures.
How do you fix a slow-draining sink?
We clear slow drains by working through a diagnostic sequence — removing the stopper, plunging, then snaking — and switch to hydro-jetting for kitchen grease buildup. Here’s the exact process.
Step-by-step drain clearing process
- Remove the stopper: Pop-up or grid strainer — hair and debris wrap around the pivot rod; pull it out and clean with a wire brush.
- Plunge the sink: Seal the overflow opening with a wet rag, then plunge 10–15 vigorous strokes — this pushes minor clogs past the P-trap into the main line.
- Snake the drain line: Remove the P-trap (bucket underneath), run a 3–6 ft drain snake into the pipe; in bathroom sinks, the clog is usually hair and soap scum right past the trap.
- Hydro-jet for grease: Kitchen sinks get 20–30 minutes of hydro-jetting — 4,000 PSI water scours grease and food particles off the pipe walls; it’s the only method that fully restores flow in older Brooklyn brownstone drains.
- Reassemble and test: Tighten the P-trap slip nuts hand-tight plus a quarter turn, run hot water for 2 minutes, and check every connection for drips.
Chemical drain cleaners damage PVC pipes and eat O-rings — we never use them and recommend against them because they create toxic fumes and weaken the pipe walls over time. For a sink drain repair that actually clears the full line, skip the pour-and-wait products and call a tech with a snake and hydro-jetter.
Cost of drain cleaning in NYC
| Drain type | Cost range | Typical cause |
|---|---|---|
| Bathroom sink drain | $120–$250 | Hair and soap scum |
| Kitchen sink drain | $150–$300 | Grease and food particles |
| Main line drain | $350–$1,000 | Tree roots or heavy buildup |
How do you fix a leaky faucet handle?
When a faucet handle leaks, it’s usually a worn cartridge or O-ring inside the valve body — we replace the faulty parts on-site in about 30 minutes.
How we replace a leaky faucet cartridge
- Shut off water: Turn the shut-off valves under the sink clockwise — cold and hot both closed before you remove anything.
- Remove the handle: Pry off the decorative cap, then unscrew the Phillips or Allen set screw holding the handle to the cartridge stem.
- Pull the old cartridge: Use a cartridge puller to extract the stuck assembly — don’t yank with pliers or you risk cracking the valve body.
- Lubricate and install: Coat the new O-rings with silicone grease, press the new cartridge in, and reassemble — handle, cap, screw.
- Test for leaks: Turn the water back on and run the faucet hot and cold — check both handle base and spout for drips.
Moen 1222 and 1225 cartridges are the most common replacements in NYC kitchens, and we always carry them in the truck because they fail every 3-5 years from mineral deposits. The whole faucet repair takes about 30 minutes start to finish.
Cost to fix a leaky faucet handle
Replacing a leaky faucet handle costs $170–$360 for a bathroom faucet or $290–$710 for a kitchen faucet, including the cartridge part ($15–$50) and labor. That price covers the diagnostic, the new cartridge, and our 1-year warranty on parts and labor — no surprise add-ons after we start the job. The labor portion eats up most of the cost because accessing the cartridge in tight NYC vanity cabinets adds 10–15 minutes just to get a basin wrench in there. If the handle still leaks after a cartridge replacement, the valve body may have a hairline crack from overtightening — that requires a full faucet replacement, not just a cartridge swap.
Can you fix a cracked porcelain sink?
Small cracks and chips in a porcelain sink can often be repaired, but structural cracks that go through the basin usually require a full replacement. Here is when each approach works.
When we can repair a cracked porcelain sink
- Hairline cracks and chips under 1 inch: We fill these with epoxy putty or filler — the area must be bone-dry for 24 hours, then sanded with 400-grit paper and painted with porcelain touch-up paint.
- Drying is the make-or-break step: Moisture trapped inside the crack prevents epoxy from bonding; we use a heat gun on low to speed the drying in older Brooklyn brownstone sinks where the porcelain is more porous.
- White porcelain matches best after a repair: Colored sinks — almond, biscuit, black — show the repair line more visibly, so we recommend replacement for colored fixtures with cracks over 1 inch.
- Epoxy glue injection for hairline cracks: We inject thin epoxy into the crack with a syringe, then clamp the area overnight; the bond holds for normal hand-washing and dish use but won’t survive a heavy impact.
When replacement is the better option
Structural cracks that go through the basin require sink replacement — epoxy won’t hold because the crack propagates under the weight of water and daily thermal expansion. In our practice, a crack that you can feel from both the top and bottom surfaces is already through the glaze and the porcelain body; patching it buys you maybe two months before it splits wider. Undermount sinks that separate from the countertop due to adhesive failure can drop suddenly — if you see the sink sagging, stop using it immediately and call for replacement before it crashes and damages the cabinet below. For pedestal sinks, a crack at the wall-mount anchor point means the entire fixture is compromised; we’ve seen those come off the wall mid-use in pre-war Manhattan buildings. We repair sink repair on all porcelain types across the five boroughs, but structural cracks get replaced, not patched.
How do you fix a garbage disposal that is clogged?
A jammed garbage disposal usually clears with the reset button and an Allen key — here is the safe procedure and when to call a pro.
Steps to clear a jammed garbage disposal
- Reset button: Press the small red button on the bottom of the unit — if it popped out, the disposal tripped its thermal overload and needs a reset before anything else.
- Manual rotation with an Allen key: Insert a 1/4-inch Allen key into the center hex socket at the bottom of the disposal and rotate the flywheel back and forth by hand — this frees most jams from bones, fruit pits, or silverware.
- Clear the obstruction with tongs: Once the flywheel turns freely, use tongs to remove whatever caused the jam — never put your hand inside the grinding chamber, even with the power off.
- Flush and test: Run cold water with a squirt of dish soap for 30 seconds, then press the reset button and turn on the disposal — if it hums but doesn’t spin, the jam is still there.
- Glass fragments: Broken glass from jars wedges between the flywheel and the shredder ring — running water won’t flush those pieces out, and they’ll score the housing, so full disposal disassembly is the only fix.
When to call a plumber for disposal issues
If the disposal still won’t turn after manual rotation and reset, or you hear a grinding noise with no movement, the motor bearings may be seized or the flywheel cracked — we disassemble the housing and clear it for $200–$400 across all five NYC boroughs. A seized motor often means the lower bearing corroded from water intrusion through the bottom seal, a common failure in units older than eight years. Running cold water during disposal use is critical — hot water melts grease that then solidifies in the drain line, causing clogs further down the pipe that require hydro-jetting to clear. On pre-war Brooklyn buildings with cast-iron waste stacks, that grease buildup can block the entire riser, so we recommend a monthly flush of ice cubes and coarse salt to keep the grinding chamber and drain line clean.
Shut-off valves, P-traps, and S-traps in NYC
Shut-off valves and traps are the two most common under-sink components that fail or need code-compliant replacement — here is what we replace and what the law requires.
P-trap vs S-trap: what’s legal in NYC?
| Feature | P-trap | S-trap |
|---|---|---|
| Shape | “P” — horizontal outlet to wall | “S” — vertical outlet through floor |
| Legal in NYC? | Yes (2022 NYC Plumbing Code) | No — creates siphon, no trap seal |
| Vent required | Vent pipe within 5 feet | No vent |
| Conversion cost | N/A | $200–$400 to convert to P-trap |
Shut-off valve replacement under the sink
- What we replace: We replace seized or leaking shut-off valves under the sink with quarter-turn ball valves — the job costs $150–$350 per valve and includes shutting off the main water, removing the old valve, and installing a new compression or push-fit valve.
- Why valves fail: Mineral buildup seizes the stem in multi-turn valves, and old packing nuts corrode — we see this most often in pre-war Manhattan buildings where the original brass angle stops haven’t been turned in decades.
- Tools we use: A basin wrench to reach the valve nut against the wall, channel locks for the compression nut, and a tubing cutter if the old valve is soldered onto copper pipe.
- When to replace both: If one shut-off valve fails, replace both hot and cold at the same time — they’re the same age and the other will likely fail within months, and doing them together saves a second service call.
Conclusion
From a loose P-trap to a cracked porcelain basin, most sink issues in NYC are fixable same-day with the right tools and parts. Here’s what matters most.
Main takeaways
Sink repair in NYC covers everything from a loose P-trap to a cracked porcelain basin — most issues are fixable same-day with the right tools and parts. The bulk of what we see breaks down into a few categories: leaking connections under the cabinet (roughly 80% of under-sink calls), slow drains from hair and grease buildup, and faucet handle leaks from worn O-rings or cartridges. Porcelain chips under an inch take epoxy filler; anything structural through the basin means replacement. And that old S-trap in a pre-war Brooklyn brownstone? It’s illegal under current NYC code and needs conversion to a P-trap with proper venting. The most important step any homeowner can take is to shut off the water at the valve when a leak appears — that single action prevents thousands of dollars in water damage while you arrange for professional repair.
