Generated explanation

Two brick masonry wall elevations show lintel-related cracking above window openings. The left elevation depicts stair-step cracks in the mortar joints above the window, identified as a pattern commonly associated with lintels sagging due to undersizing or deterioration. An arrow identifies the lintel at the window head, and the window sill is labeled below. The right elevation shows a horizontal crack along the window-head level extending beyond the opening, identified as a condition often caused by expanding, rusting steel lintels.
