Contractor Check List

As a buyer of services, you should be prepared to make your wishes known loud and clear to all contractors who are competing to be your supplier.   The following should be provided on demand from any reputable contractor: 

A listing in the phone book

A current insurance certificate

A list of professional references

Job site pictures and locations

Lien releases upon completion of the job

A written warranty/guarantee

A list of professional testimonials or references

Most contractors can produce these items; however, it is up to you to decide if a contractor is competent.  You can start by asking more probing questions that will uncover the true core competencies of the firm or in what service or solution they specialize.
