Signs of Foundation Settlement

Cracks

• Settlement cracks often occur in the foundation or the house slab or on the ceilings and walls. Small cracks are often because of minor foundation settlement or even because of expansion and contraction of the settlement. Large cracks, however, can represent a more significant concern. Cracks can warrant concern if they exceed one-quarter of an inch in width.

Windows, Doors and Plumbing

• Foundation settlement may make it difficult to open or close doors and windows because the door frame does not fit the door and causes some sticking. Gaps between the windows and doors with the frame may also occur. A door or window may not close all the way. Plumbing lines can also be affected by a poor foundation as well as mechanical equipment.

Tilted Chimney

• A tilted chimney is a sign that the foundation of a building or home has settled; however, it can be difficult to recognize unless it is severe. A slight shift in the chimney may not be as noticeable, but it is a sign of a shifting or settling foundation.

Loose Nails and Wallpaper

• When nails begin to loosen or wallpaper starts to separate from the walls, it can be a sign of a foundation problem. Nails and wallpaper shift if the walls move and they do not bind or attach to the wall any more. Bending or bowing walls can be a sign of the age of the home, settling of the foundation, deterioration of the home or shrinkage.

Slanted flooring

• Slanted or sloped flooring may be a result of foundation settlement in a specific area of the building's foundation or other structural issues, such as rotting or termite damage. In some cases, the foundation causing the sloping floor may need to be jacked up so that new footers can be installed.

Dangers

• Although some foundation settlement is normal, severe foundation settlement can cause catastrophic collapse or other dangers in some buildings. Having an inspection can help a real estate owner or potential buyer determine the severity of the settlement and determine if repair is needed.
