What Our Disposal Service Includes
Every job is different, but here is what typically comes with a garbage disposal installation and repair charleston SC visit.

Work order
Garbage Disposal Installation and Repair- Full Diagnosis: We test the outlet, check the flywheel, inspect the flange and gasket, and look for corrosion on the discharge tube. You get a clear answer on what failed and why.

Garbage Disposal Installation and Repair charleston SC
A disposal is a small appliance with a big job. Done right, it lasts a decade. Done cheap, it leaks into your cabinet and costs more to fix.
Garbage disposal installation and repair charleston SC covers everything from freeing a jammed flywheel to mounting a new 3/4-horsepower unit under your sink. We pull the trap arm, test the outlet, check the flange and gasket, and confirm the dishwasher drain connection before we call the job done. Most repairs take under an hour. Replacements usually run two to three hours once we match the mount ring and wiring.
Charleston kitchens take a beating. Grit from Lowcountry water, rice, shrimp shells, and coffee grounds chew up impellers fast. If your unit is humming but not spinning, or you see water under the cabinet, that is usually a sign the motor is seized or the seal has failed. We offer affordable garbage disposal repair charleston homeowners can schedule the same day, and we keep common Moen and Waste King sizes on the truck.

How Our Disposal Service Works

Tools and Methods We Use

Used to pull the trap arm and disconnect the discharge tube without cracking older PVC or cast-iron fittings.
Checks supply line pressure before and after install to confirm the disposal and faucet are getting proper flow.
Clears clogs downstream of the disposal in the trap or branch line. The hydro jetter handles grease and food buildup.
Inspects the main line when a kitchen sink backs up repeatedly. Confirms whether the problem is the disposal or the sewer.

How Disposal Service Runs in Charleston
Charleston kitchens deal with grit, humidity, and older plumbing. Lowcountry water carries sediment that wears impellers faster than in softer-water regions. Peninsula homes often have cast-iron drains and tight cabinet clearances that make a standard mount ring a bad fit. We plan for that.
French Quarter
Historic homes with cast-iron drains and tight under-sink cabinets. We bring compact units and adapt mount rings to fit.
West Ashley
Mix of 1970s ranches and newer builds. Older homes often need a dedicated circuit added before a new disposal goes in.
Mount Pleasant
Newer construction with PVC pipe and PEX tubing. Installs are usually straightforward and fast.

PhotoSeized Motor in West Ashley Ranch
Before: A 15-year-old 1/3-horsepower disposal was humming but not spinning. The homeowner had hit the reset button a dozen times. The motor was seized and the flange gasket was leaking.
After: We installed a new 3/4-horsepower unit, replaced the gasket, and wired it to a dedicated circuit. The sink drains clean and the cabinet is dry. Total job time was two hours.
Leaking Flange in Mount Pleasant
Before: Water pooled under the sink every time the disposal ran. The flange gasket had failed and the discharge tube was loose. The cabinet floor was starting to warp.
After: We replaced the gasket, re-seated the flange, and tightened the discharge tube. We also sealed the cabinet floor edge to prevent further moisture damage. No leaks after a full bucket test.
Restaurant Kitchen Downtime in Downtown Charleston
Before: A busy restaurant lost its disposal during Friday dinner service. The motor had burned out from years of heavy use. Staff were hand-washing dishes in a backup sink.
After: We swapped in a heavy-duty commercial unit the same evening and cleared a grease clog in the branch line. The kitchen was back online before Saturday brunch. Total downtime was four hours.
Disposal Problems We Fix in Charleston
Most disposal calls fall into a handful of categories. Here is what we see and how we handle it.
Disposal hums but will not spin
The motor is trying to turn but the flywheel is jammed.
Water leaking under the sink
A leaking disposal can warp the cabinet floor, cause mold, and drip onto wiring. Left overnight, it becomes a much bigger repair.
Disposal trips the breaker
A disposal pulling too many amps can trip the breaker every time you run it. That usually means a failing motor or an undersized circuit.
Disposal drains slowly or backs up
Slow draining after a disposal install usually means a clog downstream in the trap or branch line. Ignoring it leads to standing water and odors.

What Charleston Customers Say
Our disposal started humming and then just quit. I called at 8 a.m. and had a tech at the house by noon. He pulled the unit, showed me the seized motor, and had a new 3/4-horsepower one installed in under two hours. Clean work, fair price, and he wiped out the cabinet before he left.
Water was pooling under our sink every time we ran the disposal. Turned out the flange gasket had failed. The technician replaced it, checked the trap arm, and confirmed the dishwasher line was tight. No more leaks and he explained what not to put down the drain. Highly recommend.
Our kitchen disposal died on a Friday night during dinner service. Charleston Harborline Plumbing came out the same evening and swapped it. They knew exactly which heavy-duty unit our line needed and had it on the truck. Saved us a full weekend of hand-washing dishes.
