Foundation damage and subsidence come in many forms and can be caused by a number of issues. In Pennsylvania, the silty-loam soil can shift easily when it is saturated or there is extreme rainfall or flooding in the area. This is just one example of the issues that can cause a property to start sinking. Unfortunately, this is an issue that is difficult to spot until it has become advanced. By the time your home looks visibly uneven, the issue will have been percolating for quite some time. The earliest signs of foundation sinking or settlement will generally be seen inside your Johnstown property, usually in the basement or crawl space. Spreading cracks, dampness and humidity, pooling water, mold formation, and musty odors can all be early warning signs of mild foundation damage. These are, of course, very general signs that can indicate a number of issues. As such, it can take some time for even a professional to diagnose foundation damage from these red flags. As the issue progresses, the warning signs will become more and more specific. For example, the sign of advanced or semi-advanced foundation movement and sinking include but are not limited to large cracks, sinking concrete slabs, floor and wall gaps, and deformed window and door frames (which cause sticking and jamming windows and doors). These are all signs of general instability and movement in the structure of a property and can be a sign of sinking, lateral movement, and other issues. Finally, the most obvious sign of sinking is visible unevenness in your property, either from inside or from the street. If your property looks visibly uneven or sunken, then you should call a professional immediately and undertake repairs without delay. Waiting could be disastrous.
