When Aluminum Windows Won't Open

A sliding or a single hung window that does not open can be a real nuisance. Often, it is caused by corrosion on the exterior portion of the window frame. First, make sure that the frame is not painted shut and ensure that the frame track is not bent. Then, thoroughly coat the track where the window slides with WD-40 or another type of lubricating oil. Oil the sash clips, springs, and any other movable parts until the frame becomes unstuck and the window can be opened.

A Broken Pane of Glass

Accidents happen, and sometimes glass breaks. Fortunately, most common aluminum window frames are easily repaired. If the sliding sash is broken, remove it from the frame by loosening the rollers that hold the operable sash in place, and lift it up and out from the bottom. Next, take the frame apart by loosening the two screws found in opposite corners of the frame, and remove the broken pieces of glass. Take the frame to a glass shop for a new pane of glass, making sure to get the same glass thickness. Install the new glass within the frame and reattach the frame pieces. Reinstall the sash in the opposite manner in which it was removed.

If the fixed sash is in need of repair, first remove the operable sash as described previously, and then remove the center bar of the frame that holds the fixed panel in place. This allows you to remove the fixed sash from the frame so it can be repaired or replaced.

If you are unsure of how to repair aluminum windows with other problems, you can always remove the sash yourself and bring it to a window shop for further guidance.
