Any form of structural damage in your home can become worse, especially if left alone for a long time. Although concrete is strong, it is not the perfect material. It still requires some annual maintenance from a local expert. This allows it to be inspected every once and a while, as well as repaired when it needs to be.
Structural Damages
Once a crack has formed on your foundation wall, it always has the potential to grow larger and wider, especially if left alone. Cracks in foundation walls can extend to foundation floors, and, after years and years of neglect, they can even reach other areas of your home. You do not want this to happen to you, as structural damage in more than one area can be dangerous.
Structural damage also can cause your home to become uneven as well. This can happen via sinking, heaving, or tilting, depending on where the damage is found and how bad it is. Not only is this incredibly unsightly, but also this can make your home unsafe to inhabit.
Water Damages
Any opening in your foundation wall is an invitation for water to enter through. Water damage is quite common and can be one of the most expensive damages to repair. Some of these include:
Mold and mildew  Wood rot  Musty odors  Water stains
Leaks and floods also can introduce pests, both big and small. Many common insect pests are attracted to wet, humid environments, and cracks in foundation walls are the perfect way for them to enter your home. Larger pests, such as rodents, also can be tempted to enter your home through any available openings.
