If there are perceived construction defects with the custom home being constructed caused by the framer subcontractor, the ultimate responsibility in getting these defects rectified lies with the general contractor that you have written about. I recommend that you carefully read your contract with the general contractor in that its terms and conditions control the obligations owed to you and vice versa in the absence of conflicting state law.Given the problems with the home, I suggest that you first sit down with the general contractor to see how he or she intends to resolve the framer's defective workmanship and then confirm such in writing with him or her with a set course of action and time line.If the general contractor's explanation for resolution of this dispute does not meet your satisfaction, you need to then consult with an attorney experienced in construction law.Good luck.
