Lintel

Definition and meaning of Lintel in real estate.

A lintel is a horizontal structural beam that spans the opening between two vertical supports, such as a door or window. It bears the weight of the masonry or structure directly above it, transferring the load to the surrounding walls.

In more detail

In residential construction, lintels are made of steel, concrete, stone, or wood depending on the building style and load requirements. Without a strong lintel, the wall above a window or door frame would sag, crack, or eventually collapse. Home inspectors carefully check for cracked brick or sagging masonry above openings, which are primary signs of lintel failure or rust. Properly installed lintels are crucial for maintaining the structural integrity of a building over time.
