Are My Foundation and Basement Cracks Always a Problem?

Foundation and basement cracks don’t need to be extreme to be a problem. Some people think that only very significant cracks are a problem, but that couldn’t be further from the truth. Many types of foundation and basement cracks are a big issue. 

• Hairline Cracks 

This is the only type of crack that isn’t necessarily a problem. A hairline crack is very small, not even large enough to fit a business card into. These types of cracks can form for a variety of reasons, but as long as they don’t extend through the concrete, they’re not necessarily a problem. Still, if you’re starting to see a lot of them in a short period, you may want to call someone in to inspect. 

Hairline cracks can be caused by several things, many of which are perfectly natural and non-harmful. The settling of a property, for example, or the reaction of concrete to changing temperatures can cause hairline cracks. However, they can also be a precursor to far more serious issues that will require inspection, so you should monitor known cracks. 

• Any Other Foundation and Basement Cracks 

Any cracks that aren’t hairline cracks are potentially a sign of a serious problem at work. If you’re seeing a foundation or basement crack, that is a sign that something is wrong. The problem isn’t the crack; the problem is whatever caused the crack to form in the first place. Foundation and basement cracks are always a problem. 

At the heart of it, cracks are caused either by excessive pressure or by shifting in the structure of the property (usually a mix of both). This is why it is important to call a professional in to inspect growing cracks; there are so many potential causes to consider. From settlement, subsidence, and excessive hydrostatic pressure to flaws within the structure of a property, cracks really can come from anywhere.
