Vertical and diagonal cracks are not always a cause for alarm, they often indicate a less serious issue but could lead to problems down the line if not monitored. Here are some causes of vertical and diagonal cracks:

Concrete Settling: Settling in the concrete foundation is quite common in new construction. Since concrete shrinks while it cures this can cause vertical and diagonal cracks. Typically if concrete settling is the cause of the crack it will be located in the middle section of the wall, the corner of a window or by a door opening. These types of vertical/diagonal cracks are perfectly normal as long as the crack is 1/8 of an inch or less.

A More Serious Issue: If the vertical or diagonal crack is located close to the corner of a wall and is wider than the 1/8 of an inch this is probably due to overloading which is a structural hazard. This is something you will need a professional foundation crack specialist to evaluate.

Stair Step Cracks

Any form of masonry is prone to stair-step cracks. When you see this type of a crack it could be a serious threat since they typically appear along mortar joints, which are vital to your foundation. Here are the two main causes of stair-step cracks:

While it is common to see hairline cracks along the mortar joints anything bigger than 1/8 of an inch is a serious problem.

Foundation Slab Cracks

A poured concrete slab is prone to develop cracks over time. If you know what the cause of the crack is you will have a better understanding of what steps you need to take. Here are three common reasons for foundation slab cracks:
