If you have dropped and bowing brickwork above your garage door, in all likelihood your lintel needs to be replaced. A lintel is the horizontal support above door openings and windows. If installed too short, the weight of the brick or stone will force the lintel to bow, which can lead to collapse. Because it is steel, it can rust severely over the years. This causes a structural defect which create cracks around door/window/garage openings due to the expansion of the rust.D
