Swinging Door

I have two double hung windows, double sash, each sash is 30 x 32 setting side by side. The windows are on the first floor, setting in a box extending 6 inches from the flush side of the house. The problem is that the window frame has settled approximately one inch increasing the size of the window frame. Thus, there is a small gap in the corners of each window. I did speak to a contracter who indicated that he could jack up the window frame which would correct the settling problem. I would like to correct this problem but I do not want to break anything. Does this sound like a way to correct the settling problem? Is this a common practice in the industry? Thanks. Kkay

My friend wants to remove a large glass block window (approx 4 x 6) and replace with a sliding window in his kitchen. It is the old kind--the insert vent doesn't work anymore and the glass generates quite a bit of heat in the summer months. The intention is to have a company remove the old block and haul away--we would be installing the new slider ourselves. I have installed vinyl replacement windows before with no major problems. My question is -- should we be concerned about potential damage to the window opening due to the glass block coming out? Or is the removal process a simple matter? Just want to be prepared in case. Thanks!
