Original units from the 1970s-1990s tract wave
A disposal typically runs eight to twelve years, and a large share of Davie’s original units from that build wave are now well past that mark.
Freed, reset, or swapped for a new one
A disposal that hums without spinning, one that gives no response at all, or one that has simply reached the end of its run: we work out which and clear it, or swap it for a correctly sized replacement.
Why does a garbage disposal hum but refuse to spin?
That sound means the motor still has power and is pushing against something it cannot move past, almost always a hard scrap, a dropped utensil, or stringy produce wedged where the spinning plate meets the housing. It is a mechanical stoppage, not an electrical one. Most disposals build in two ways around exactly this: a small red reset button on the underside, and a hex-shaped socket at the center made for turning the plate free by hand. Between the two, most jams clear before a call is even needed.
Complete silence is a different animal, and usually traces back to a tripped breaker, a bad switch, or a wiring fault rather than anything mechanical inside the unit. Sorting out which one it is matters, because a unit that only needed a button pressed does not need to be replaced, and we check the wiring before ever recommending a new disposal.
What we diagnose
Four patterns account for most disposal calls we take.
A jam in most cases, cleared without replacing the unit more often than not.
A worn seal where the disposal meets the sink flange, or on an older unit, a housing that has simply cracked with age.
Sometimes it is the disposal, sometimes the branch line right after it. A camera or a snake past the unit tells us which.
Often electrical: a tripped breaker, a failed switch, or wiring, rather than the grinding mechanism itself.

Around Davie’s kitchens
A few things about Davie’s housing stock show up again and again on these calls.
A disposal typically runs eight to twelve years, and a large share of Davie’s original units from that build wave are now well past that mark.
West of University Drive, a disposal working hard against fibrous scraps is a common contributor to problems downstream in a septic system rather than municipal sewer.
Most Davie kitchens run the disposal on its own outlet under the sink, and we confirm it is wired and grounded correctly on any replacement.
Before you call
Most manufacturers build a manual reset button and a hex-key opening into the base for exactly this. Try those first, but never put a hand inside the chamber, and stop and call if a jam will not budge.
Fibrous vegetables like celery, large amounts of coffee grounds, grease, and bones are the usual culprits behind a jam. Running water during and after use helps a lot too.
A cracked housing, a leak from the unit body itself, or a motor that has simply worn out all point toward replacement rather than another repair.
A larger household running the disposal hard often does benefit from the jump: fewer jams, tougher scraps handled without strain. We will tell you honestly if your kitchen does not need it.
Disposal jammed or dead?
A jam gets freed most of the time. When it does not, we put in a unit sized correctly for the kitchen.
