Difficult or stuck doors and windows are another warning sign that the foundation below is failing to secure the structure above. Doors often won’t close or stay shut, and sometimes the door frame will be crooked, have gaps or even cracks. Windows will be sticky or even completely stuck shut, and even sometimes begin to develop warpage and leaks. These types of issues are more than unsightly or annoying, they are warning signs that the structural integrity of the foundation has been compromised and is in need of repairs. Home’s can lose significant value at the time of resale if found to have structural foundation issues.
What is causing your doors and windows to be difficult to open and shut? Simply put, the soil your foundation was built on isn’t stable and was poorly compacted during construction. We call this top layer of soil the “active zone”. Depending on the amount of clay, sand, and organic matter in your soil, it’s unique geologic composition can present a variety of problematic reactions to an extended period of wet, dry, hot or cold conditions. When soil stays too dry, it shrinks and creates voids where a foundation will settle. When soil stays too wet, it gets soft and cannot bear the heavy loads and a foundation will sink. When soil freezes, it will expand and heave the foundation upwards. All of these soil conditions put pressure on a foundation which then causes damage to it and the structure above.
