Hi there, I have just moved into an 85-year-old home. It appears the previous owner did not use a clothes dryer as there is no venting ductwork in the basement. Looking at my neighbors' houses, many of them have vented through a basement window by boarding up half with plywood and cutting a hole in the board. I would like to avoid this because A) it looks ugly, B) I don't want to sacrifice the light coming through the window, and C) the windows are on the opposite side of the basement. So my question is, can I cut a 4" hole in one of the blocks of the glass block windows closer to the dryer? Could I remove one of those blocks entirely? My go-to repair guy suggested cutting a hole through the brick wall and venting it that way, but I don't want to threaten the structural integrity at all. The house is in decent shape for how old it is, but I don't want to tempt fate for a 4" duct. Thanks for all your help so far. This forum has been a great resource.
