Garbage Disposal Repair Services in Nassau & Suffolk Counties

Garbage disposals tend to fail in predictable ways. Our licensed plumbers can quickly diagnose the issue and provide a proper repair that is done right the first time for homeowners across Long Island.

Garbage Disposal Won't Turn On

If your unit is completely silent when you flip the switch, it could be a tripped reset button or a circuit breaker issue. However, if those quick checks do not solve the problem, it likely means a failed motor or an internal wiring issue. In those cases, a licensed plumber is the right call to handle the electrical diagnosis and repair.

Disposal Hums But Won't Grind

When power reaches the unit but the grinding plate is not spinning, you likely have a jammed impeller. This often happens when a foreign object, like a fruit pit or a stray utensil, gets lodged in the chamber. While you can sometimes clear a minor jam yourself, professional service is needed if the jam keeps recurring or if the motor has been running hot to avoid a complete burnout.

Garbage Disposal Is Leaking

A leaking disposal is a serious concern because it can quickly cause water damage to your kitchen cabinets and subfloor. Most leaks happen at the sink flange at the top or where the dishwasher line connects to the unit. However, if you see water dripping from the very bottom of the unit, it usually means an internal seal has failed, and it is time for a replacement.

Making Loud or Unusual Noises

Rattling, clanking, or high-pitched screeching are clear signs that something is wrong. It could be a piece of metal caught in the chamber, or it might be a sign that the bearings and grinding components are wearing out. Running a noisy disposal can accelerate the damage, so a professional inspection is the smartest next step.

Disposal Drains Slowly

Because your disposal discharges directly into your kitchen drain, a clog further down the line can look like a disposal problem. We can determine if the blockage is right at the unit’s discharge elbow or if you need a more thorough drain cleaning service to get things moving again

Garbage Disposal Installation & Replacement

Not every disposal problem is worth a repair. If your unit is older, has a failed motor, or is leaking from the bottom, replacing it entirely is often the more cost-effective path. T.F. O’Brien handles full installation and replacement for Nassau and Suffolk County homeowners. We take care of removing the old unit, installing the new one, and ensuring all drain and dishwasher connections are perfectly sealed.

When to Repair vs. Replace

We typically recommend a repair if the unit is less than eight years old and the problem is a specific, fixable part (such as a gasket) or a jam. Replacement is usually the better choice for units over ten years old or those experiencing major motor failure. We will always give you an honest, professional opinion so you can make the right call for your home.

Who Should You Call to Fix a Garbage Disposal?

A licensed plumber is the right professional for this job. Because the disposal is connected directly to your kitchen’s drain line, any work involving the flange or the discharge connection requires plumbing expertise. While a handyman might fix a visible problem, a licensed plumber ensures the underlying plumbing and electrical connections are safe and meet New York codes.
