Above most windows and doors you will have some form of lintel. Commonly these are brick lintels, steel lintels or concrete lintels. The first signs of a problem with a lintel are usually cracks in the masonry above the windows and doors. What should you do if you notice cracks above a window or door?

Similarly, What is lintel failure?

Most doors and windows have a lintel above, meaning that lintel failure is a common problem whether the lintel is made from brick, steel or concrete. Problems with lintels usually manifest themselves as diagonal cracks or step cracking in the masonry above doors and windows.

Also, Is it OK to drill into a lintel? Drill through the concrete/plaster until you hit the lintel, change the bit to HSS, drill through the steel. Change back to the masonry bit if more concrete present or you will just knacker the HSS drill bit! You don’t have to spend a fortune, as long as the bit is HSS, it’s OK.
