Concrete lintels are a widely used and are a reliable way to support masonry above doors, windows, and other wall openings. They are valued for their strength, durability, and compatibility with brick and block construction. However, concrete lintels can develop problems over time if they are affected by moisture, corrosion, movement, overloading, or poor installation.

Understanding the common signs of lintel damage and knowing when repair or replacement may be needed can help prevent more serious structural issues. Here’s what to keep in mind.

What are common problems with concrete lintels?

Concrete lintels can develop several issues over time, especially when exposed to weather, moisture, structural movement, or inadequate support conditions. The most common problems include cracking, spalling, rust staining, corrosion of embedded reinforcement, and sagging above openings.

Cracks above doors and windows are often the first visible sign that something is wrong. Some cracks may be minor

A lintel is a horizontal support placed above an opening in a wall, such as a door or window. Its purpose is to carry the load of the wall or structure above that opening and transfer it safely to the building elements on either side. Without a lintel, the material above the opening would not be properly supported, which can lead to cracking, movement, or structural failure over time.

Lintels are used in many forms of construction, especially where masonry, brick, block, stone, or other heavy wall materials sit above openings. While they are a basic structural element, many property owners do not notice them until they are planning a renovation, replacing windows, or dealing with cracks above a door or window.

What are lintels used for?

Lintels are used to bridge openings in walls and support the load above them. They are an essential part of construction. When a wall has a gap for a door or window, the lintel provides that support.

So, practically, lintels:

• carry wall loads above openings
