One of Your Building's Biggest Threats: Lintel Deterioration
Posted 2014-08-08 by Bob Neas in Lintel Repair

What to Look For?

A lintel is a horizontal support above doors and windows that carries the masonry above it. It also is found mid wall in large masonry walls to transfer the weight of masonry above to the building frame, commonly referred to as a shelf angle.

One of the early signs of lintel deterioration is mortar cracks beginning at the upper corners of masonry openings such as doors and windows. Once the damage progresses water infiltration will cause the lintel to rust, this causes the steel to expand known as rust jacking. The lintel if it has begun to rust jack will appear to bow and at that point mortar and even masonry units (brick and stone) may come loose or begin falling.

Why is Lintel Deterioration Such a Problem?

First off it is extremely dangerous because masonry and debris can quickly become loose and fall, a very unwanted liability. If neglected eventually a buildings structural integrity will become compromised.

Secondly lintel deterioration progresses fairly rapidly go right here and when it becomes advanced whole sections of the masonry wall may need to be rebuilt resulting in high costs to repair.
