I recently had 9 replacement double-hung vinyl windows installed in my home and 4 out of the 9 don't seem to close correctly. There is a vinyl groove on each sliding pane of the windows which are supposed to interlock, but some of the windows need to be pushed in hard and then pushed down in order for them to interlock. The window installer told me that "double-hung windows are supposed to be pushed in and then down in order to close", but only half of my windows require this. Is the installer B.S.ing me, or is this truly the case with double-hung windows?

I'm planning on removing the old sliding-doors in our bedroom closet and replacing them with bifold or slab doors (haven't decided which yet). The closet from inside frame to inside frame is 59 1/2 inches wide. I've been looking into options from big-box stores (Lowe's and HD) and it seems that, without going custom, my choices would have to be two 28" doors. But even that would be a few inches too narrow. So then my question is, how feasible would it be to just run a piece of wood up either side of the inside frame, approximately 1" thick (and then paint it to look like part of the frame) so it's basically making the closet slightly narrower and thus having the doors fit better? Has anyone tried that? As long as the extra piece on either side is secured well to the frame, would there be any perceivable issues with the door being attached to the piece of wood rather than the frame itself, even though the screws could theoretically be long enough to go through the shim and into the frame?
