Contractor warrantees guarantee the work's quality for a particular duration of time, much like a warranty for a particular piece of electronic equipment purchased at a store. However, while the parts themselves may be under separate manufacture's warrantee, contractors' warrantees are specifically for the work involved, and provide an extended kind of protection to ensure the quality of the workmanship as well as the component parts. These are meant to provide an added level of protection for the individual contracting the work.
