Cracks in your foundation, no matter how large or small, provide an easy route for water to enter your home. Water can enter multiple ways too – from rain to melting snow and high humidity levels.
Once water enters your foundation, it can begin deteriorating its structural integrity quickly. If that isn't bad enough you can also expect foundation cracks to grow larger as water flows through. So even the smallest crack or gap can lead to major foundation and structural repair problems if left untreated.

Of the foundation cracks you are likely to encounter, vertical cracks are generally the most common and least severe type of crack you will come across. Vertical cracks are cracks that go straight up and down, or maybe on a slight diagonal of within 30 degrees of vertical, and are a common occurrence in many houses. These types of cracks are usually the result of your foundation settling, and it is thusly not uncommon even for new houses to have this type of foundation damage as a home’s foundation can settle greatly in the first few years. Fortunately, this type of crack is usually the easiest and least expensive to have sealed.
Diagonal cracks run along your foundation or basement wall at a 30-75 degree angle. This type of crack may be a thin hairline crack, but will likely be wider at one end than the other. Diagonal foundation cracks are caused by differential settling of a foundation, which is where one side of a home’s foundation settles lower than the rest of the foundation. This type of uneven tension then causes diagonal cracking. Differential settling can be the result of the house being built on a hill, or due to the expansion or contraction of the soil under a portion of the home. This type of crack can be more costly to repair than a vertical crack since it may be necessary to address the cause of the differential settlement after the crack is sealed.
Foundation cracks that run sideways (horizontally) are the most serious type of crack to look out for, as they can signal serious damage to your home’s foundation and structural integrity. While these cracks are sometimes seen in homes with poured concrete foundations, they are most common in homes with concrete block or brick foundations. Several things can cause this type of foundation damage including soil pressure outside of your foundation, and hydrostatic pressure that can cause your basement walls to bow. If you discover this type of foundation damage it is important that you have it repaired as soon as possible before the structural integrity of your home becomes compromised. This type of cracking will require the most extensive repairs, which will likely include reinforcing your foundation in order to secure it and prevent further damage.
Knowing what types of cracking you may discover in your home can help you to determine the severity of the damage to your foundation. Ultimately, however, any cracks you discover in your home’s foundation should be taken seriously and professionally inspected and repaired so that you can ensure the structural integrity of your home.
