Oftentimes, the lintel above garage door openings can begin to sag over periods of time. Is it more common in two-car garages due to the higher pressure placed on the lintel to support a longer opening. However, regardless of the size of your garage, it is important to keep an eye out for sagging lintels. Sagging is a telltale sign that the lintel is failing and not providing adequate support to the structure. It is important that these issues get addressed quickly, as they can rapidly develop into more serious structural problems.
Sagging lintels can be a result of many things. These can be installation errors such as lack of space for the lintel to expand in warmer months, causing pressure on the structure, as well as environmental elements and deterioration over time. If left unaddressed, the structure can lose all support and collapse. This can be a major safety concern for those who may walk into and out of the garage, and can also cause damage to vehicles that may occupy the garage. If you notice signs of sagging lintels, be sure to contact a professional immediately.
