Garbage Disposal Installation & Replacement
A garbage disposal is one of the simpler plumbing jobs, but it still needs proper drain connection, mounting, and often an electrical outlet under the sink. A.J. LeBlanc Heating installs all major brands and sizes across Southern NH and handles the plumbing side completely. If an outlet is needed, we coordinate the electrical work too.

Garbage Disposal Repair
A jammed, leaking, or dead disposal can often be repaired rather than replaced. A.J. LeBlanc Heating's plumbers diagnose the problem and let you know whether a repair or replacement makes more sense, with an honest recommendation either way.
- Jammed disposal: reset or clearing
- Leaking disposal: gasket or flange repair
- Humming but not spinning: motor or jam diagnosis
- Disposal not turning on: switch or outlet check
- Full replacement when repair isn't cost-effective
- Same-day service on most calls
Garbage Disposal FAQ
How much does garbage disposal installation cost?
A garbage disposal installation in Southern NH typically runs $300 to $500 installed, depending on whether an electrical outlet is needed and the cost of the disposal itself. A.J. LeBlanc Heating provides upfront quotes.
What size disposal do I need?
For most households, a 1/2 HP disposal handles everyday use. For heavier use or harder-to-grind food waste, a 3/4 or 1 HP unit is worth the upgrade. A.J. LeBlanc Heating recommends based on your usage.
My disposal just hums but doesn't spin, is it broken?
Not necessarily. It is probably jammed. There is a hex key port on the bottom of most disposals. Inserting a 1/4-inch hex key and turning it back and forth usually frees the jam. If that does not work, call A.J. LeBlanc Heating.
Do you need an electrician for disposal installation?
Only if there is no outlet under the sink. If there is one, the plumbing connection is all that is needed. If not, A.J. LeBlanc Heating handles both the plumbing and the electrical.
