lintel
cracked glass
window sill
a missing or undersized lintel can put pressure on windows so that they are hard to open and/or the glass may crack
settlement cracks are likely if the wall is masonry

Generated explanation

The illustration shows a three-section window set in a brick masonry wall above a projecting sill. The lintel and masonry above the opening sag toward the center, with a large downward arrow indicating pressure on the window assembly. Stepped settlement cracks extend through mortar joints above both sides of the opening. The upper pane of the center window is cracked. The annotations explain that a missing or undersized lintel can load the windows, making them difficult to open and potentially cracking the glass.
