Do It Yourself

Replacing a garbage disposal yourself costs about $100, or the cost of the unit.  The project takes about four hours to complete.

Saving a couple hundred bucks makes sense for those with plumbing and electrical know-how. 


Bottom Line

If you don't mind getting your hands dirty and have some plumbing experience and the time to do it, put in the disposal yourself.
