Keep an eye out for cracks in walls, floors, or ceilings, both inside and outside your property. These may indicate foundation movement or settlement, especially if they are widening or appearing suddenly.

Uneven Floors

Uneven or sloping floors can signal foundation issues, causing structural instability. If you notice floors that feel uneven or seem to slope, it's essential to have a professional inspection to determine the underlying cause.

Doors and Windows

Difficulty opening or closing doors and windows, or doors that stick or no longer latch properly, could be a sign of foundation settlement. This occurs as the foundation shifts, causing misalignment in the door and window frames.

Water Damage

Moisture or water pooling around the foundation, especially after rainfall, can lead to foundation problems such as erosion or soil expansion. Pay attention to damp spots, mold growth, or standing water near the base of your home, as these can indicate drainage issues or foundation damage.
