I just hired someone to refinish my basement. Here are some pictures of his framing around the Ductwork.. First picture, he screwed wood frame directly into the ductwork and then added some support on top of it. Second pictures are the framing on the side of ductwork it looks like he attached a wood 2x2 lining the cieling near the duct, hung the Sheetrock from that woood, dropping just beneath the duct and added another 2X2 that lines the bottom of the sheet rock. Should he be hanging the Sheetrock like that? Third picture shows there are no wood framing for the Sheetrock from the ceiling that’s dropping from the ceiling..
