Our General Contractor asked for checks which we now realize were very far ahead of milestones in the contract. He is now dragging his feet on ordering materials. What should we do? Should we send him a letter stating the total payment amount relative to the contract total along with a list of work still to be performed to document where we are? We know that if he refuses to do work unless we give him more money that it is a police matter. It hasn't come to that, but there have been significant delays in work. This is an extensive remodeling project, total value in realm of $500K.
