4. Do you have local references?
Check references carefully. Current references are only valuable to see if the owner is happy with the contractor’s work, but only long term references are the proof of actual performance of the contractor’s work.
Most failed construction projects do not happen quickly, but deteriorate over a period of years. New project references should carry minimal weight in the decision making process vs. long term projects.
A professional contractor will gladly provide references and want you to speak with his past customers.
Automatically reject any contractors who cannot provide a reference list of customers.
