My husband and I just had someone give us an estimate on finishing the already hung drywall in our den. It is a 18 x 25 square room with 4 windows, fireplace, and large doorway. Approx 18 pieces of 4x8 sheets. The pieces are hung very well - tight seams. He quoted us $480.00 just to finish the walls (not the ceiling) (that's including the materials) That price seems very steap. Does anyone know what the approx. going rate is for drywall finishers?
