Retainage is always a good idea. Contractors respect one thing at least. The money. The one who holds the money has the power. 5% of each progress payment should be retained. At least. Those monies are finally distributed when the project is 'closed out.' Assuming there are no creditors. You see, the owner (that's you, Byron) is usually left holding the bag if material suppliers or subcontractors were not paid. The prime contractor's debts to them can become a lien on your property. So......the damage is not just limited to the money you pay to the prime.
