Do cracks in your basement walls keep have you worried about what’s to come? A lot of homeowners may not notice a hairline crack or two right away, which may not be a major issue.

You might find the first warning signs of structural damage in the interior of your house. Besides drywall cracks you may witness signs such as bowed walls, gaps where walls and floors meet, nails popped out of drywall, bouncy or tilting floors, jammed doors or windows, or cabinets that open by themselves.

Turning to the outside, small cracks in the exterior walls of the structure typically aren’t serious. The most prominent and least severe kinds of cracks are vertical in nature. They run up and down and are often caused by foundation settlement. The good news is that foundation settling is common – even in newer construction.

You might also see diagonal cracks that run at an angle. This type of cracking is the result of differential settling. In this instance, one side of a house’s foundation is sinking lower than the rest of the structure.

The most serious type of cracking run horizontally. These cracks are a symptom of a more serious structural issue, such as soil pressure or hydrostatic pressure that cause the basement walls to tip, bow and buckle. The weather in your area can be a factor as ice and snow, excessive heat or rain, or extensive flooding and droughts can lead to the contraction and expansion of soils.
