In a working household, a dead disposal is a small problem that causes a lot of trouble. The kitchen gets hard to use, and the sink often backs up too. Sorting it out starts with a short list. A hum without any spin is usually a jam, which is the most common problem and the easiest to fix. A leak below is often the seals or the housing, and the contractor checks which. Total silence usually points to the electrical side or the motor, and once the motor has died, a new unit is usually the answer.
Jams are the most common call, and clearing one takes the right tool plus a check of whether the jam strained the motor, since a strained motor can fail again soon after and mean another call. Leaks deserve the same attention, because a slow drip under a busy sink can go unnoticed until the cabinet is damaged, and by then there's more to repair.
When replacement makes more sense, the numbers get explained plainly to whoever makes the call. The new unit gets matched to how the kitchen is really used and installed with the connections done right, with clear paperwork for your records when you need it. You get straight answers and clear updates, explained without a lot of extra talk.
