Garbage disposal jammed, dishwasher leaking under the cabinet, or planning a full remodel? We handle the kitchen plumbing side of single-fixture swaps and full renovations across Hempstead.
The kitchen sees more daily plumbing wear than any other room. Disposals jam, dishwasher supply lines develop pinhole leaks, ice-maker lines tee off the cold supply with cheap saddle valves and start dripping behind the fridge years later. Most kitchen plumbers near me searches in Hempstead are about one of those three.
We handle them all. Garbage disposal installation, garbage disposal repair, full garbage disposal replacement when a unit is leaking from the body or seized solid. We carry standard and premium InSinkErator and Waste King units in stock so most installs are same-day. Dishwasher hookups on new installs and unit swaps. Ice-maker line repair when the saddle valve fails and replacing the whole supply with a proper shutoff and braided line.
For full kitchen renovations we rough in supply, drain, vent, and gas lines for islands, pot fillers, instant-hot taps, and reverse-osmosis drinking water systems, and we coordinate timing so cabinet and counter installers are not waiting on the plumber. Every kitchen plumbing job is pressure tested and run under load before we leave.
Common Kitchen Calls
Three Kinds of Kitchen Plumbing Visits
Most calls fall into one of three buckets. Knowing which one helps us bring the right parts on the first visit.
Garbage Disposal
Disposal will not turn, hums but does not spin, leaks from the body, or rattles like a bag of nails. Most jams clear with the reset button or an Allen key. The leaks and the seized motors mean replacement, and we usually have an InSinkErator in the same horsepower class on the truck.
Dishwasher & Ice-Maker
New dishwasher install, replacement after a leak, or an ice-maker line that has been dripping behind the fridge for years. We swap saddle valves for proper quarter-turn shutoffs, run new lines in copper or PEX, and pressure test before we leave.
Kitchen Remodel
Full kitchen renovation with new cabinets, an island, or a relocated sink. Rough-in for supply, drain, vent, gas (if applicable), and any add-ons (pot filler, instant-hot, reverse osmosis). Permit-pulled with the Town of Hempstead and coordinated with your contractor.
If your situation is just a slow kitchen sink drain, that is a drain cleaning call rather than a kitchen plumbing call. We do that too, but it lives on a different page. Send us photos and we will route you to the right service on the call.
Project Scopes
Single Fixture or Full Remodel
The biggest cost driver is whether anything is moving locations. Same-spot swaps are quick. Moving the sink to an island is a project.
Single FixtureSame Spot Swap
Disposal, dishwasher, ice-maker, or sink in the existing location. Most are finished in one to two hours. We disconnect the old, install the new, replace any tired shutoff valves, and pressure test under load. No permit needed for like-for-like swaps.
Full RemodelNew Layout
Sink relocated, island added, pot filler installed, or new appliances roughed in. Includes supply and drain rough-ins to new fixture locations, gas-line work for ranges, and a Nassau County permit. Coordinated with your contractor on cabinet and counter timing. Multi-day project across the renovation window.
For full remodels we get involved at the design phase so the rough-in lands right the first time. Drain centerline, supply stub-out heights, and cabinet cutouts all matter to the cabinet installer. Calling us early saves rework once cabinets are set.
For single-fixture work we usually slot it into the regular schedule within a day or two. If the disposal is leaking onto the cabinet floor right now, we hold same-day slots for active leaks.
What's Included
Flat-Rate Pricing, Pressure Tested Before We Leave
Flat-rate visit fee
Every call starts with a flat trip charge that is applied toward the work. We do not bill an hourly clock that runs while a junior tech tries to figure out which part of the disposal is making noise.
Written estimate before the work
Whether it is a disposal swap or a full kitchen rough-in, you get a written estimate covering parts, labor, and any add-ons (new shutoffs, supply lines, code-required upgrades) before any tools come out.
One-year workmanship warranty
Every install we do carries a written workmanship warranty on connections and fittings. Manufacturer warranties on disposals, dishwashers, ice-makers, and pot fillers are passed through; we register them on day one when applicable.
Old unit hauled away, area left clean
Disposals, dishwashers, and old appliances are removed and disposed of properly. We sweep the cabinet floor, wipe drips, and leave the kitchen the way we found it. You do not have a 60-pound disposal sitting on the curb waiting for sanitation.
How It Works
Four Steps from Phone Call to Finished Kitchen
Single-fixture swaps usually finish in a single visit. Full remodels move through these four stages across the project window.
1
Phone consultation
Tell us what is happening: a leaking disposal, a new dishwasher arriving Tuesday, or a remodel breaking ground next month. We scope it on the call, send a quote where possible, and schedule the visit.
2
On-site walkthrough
For remodels, we come out, look at the existing plumbing, the planned cabinet and appliance layout, and write a flat-rate quote. For single-fixture work we go straight to the fix on the same visit.
3
Install, rough-in, or repair
Single-fixture: disconnect old, install new, swap any tired shutoffs, pressure test. Remodel: rough in supply, drain, vent, and gas to the new layout, set fixtures after cabinets are in, and coordinate with the contractor.
4
Run-under-load test
Before we leave, every kitchen plumbing job runs under live water. Disposals are tested under load. Dishwashers run a fill cycle. Ice-makers fill once. Supply and drain connections get checked for drips. You sign off only after everything works.

Every Common Kitchen Plumbing Job in Hempstead
From a quick disposal swap to a full island rough-in, here is the work we run most often.
Garbage Disposal Installation
New garbage disposal installation in a kitchen that did not have one before, or upgrading from a 1/3 hp unit to 1/2 or 3/4 horsepower. Includes new mounting flange, drain tie-in, dedicated switch verification, and a pressure-tested run-under-load.
Garbage Disposal Repair
Disposal humming but not turning, leaking from the body, or rattling. We fix garbage disposal jams that the reset button will not, replace seized motors, and resolve sink-side leaks at the flange. Most calls finish in under an hour.
Dishwasher Hookup
New dishwasher install or replacement after a leak. Hot supply, drain hose tie-in to the disposal or air-gap, and dedicated quarter-turn shutoff. We coordinate with your appliance delivery so the unit lands ready to plug in.
Ice-Maker Line
New ice-maker line for a fridge that did not have one, or replacing the saddle valve and plastic tubing many older homes have with a proper quarter-turn shutoff and braided supply. Stops the slow drips that wreck cabinet bottoms.
Pot Filler
Wall-mounted pot filler installation behind the range. Includes new cold-supply line through the wall, dedicated shutoff inside the cabinet, and finish-trim install after tile is up. Common upgrade on Hempstead remodels.
Instant-Hot Tap
Under-sink tank and dedicated tap for instant boiling water. We mount the tank, run the supply, and install the tap. The cabinet electrical needs to be in place; we coordinate with your electrician if you do not have it yet.
Reverse Osmosis
Under-sink reverse-osmosis drinking water systems. Three or four stage units, dedicated drinking-water tap on the sink deck, and tie-in to the existing cold supply. Annual filter change visits available on a maintenance plan.
Sink Drain Rough-In
For remodels and sink relocations: new 1.5-inch drain run, P-trap, and connection to the wall stack with proper venting. Tied to the new cabinet layout so the trap is centered under the sink, not pushed off to one side.
Supply Line Rough-In
For remodels: new half-inch hot and cold supply runs in PEX or copper, sized for sink, dishwasher, ice-maker, pot filler, and any other fixtures the new layout adds. Pressure tested before walls and cabinets close.
Disposal or Dishwasher Leaking?
Call. We diagnose on the phone, dispatch a same-day truck, and stop the leak before more cabinet floor gets ruined.
Common questions we get on the phone before scheduling.
A standard 1/2 horsepower garbage disposal installation in Hempstead typically runs $325 to $475 installed, including the unit, mounting hardware, drain connections, and the run-under-load test. Premium 3/4 hp units with sound insulation run $425 to $625. The garbage disposal installation cost is locked in before the work starts; no surprise upcharges.
Hum-but-no-spin and most jams are repairs (a quick fix). A leak from the body of the unit, a seized motor that will not start at all, or rust on the bottom housing means replacement; the unit is at end of life. We give you both numbers on the spot. Most disposals last 8 to 12 years; if yours is in that range and acting up, replacement is usually the better spend.
Almost always, yes. The hot supply line and drain connection are standard. Older homes sometimes have a tired multi-turn shutoff valve that we replace with a quarter-turn during the install (it makes future service easier). If the drain line ties to a disposal that is also on its last legs, we will quote both at once so you do not pay two trip charges.
If we are running a new cold-water supply line through the wall, yes, the Town of Hempstead requires a plumbing permit. We pull it as part of the install. The permit and inspection are included in the written quote, so the price you see covers it.
If your household drinks bottled water, the math usually works out in favor of an under-sink reverse-osmosis system within a year or two. Hempstead water is on the harder side, and an RO unit also reduces the chlorine taste many homeowners notice. The annual filter cost runs roughly $50 to $100 depending on the system.
A typical kitchen rough-in is two to three days of plumbing time spread across the project. Day one for supply and drain rough-in to the new fixture locations, day two after cabinets and counter are set for fixture installation, and a final visit if the inspection or appliance delivery falls on a different day. We coordinate timing with your contractor so plumbing does not hold up the project.

Drain Cleaning
If the kitchen sink is slow or backed up, drain cleaning is the answer. Snake or jet, depending on the line and the cause.
