What is a common sign of improper drainage around a property?

Water pooling in yards or around the foundation is a clear indicator of improper drainage around a property. This condition can arise when the grading of the landscape does not direct water away from the foundation, leading to saturation of the soil in these areas. Pooling water can cause significant issues, including potential flooding in basements and crawl spaces, increased pressure against the foundation walls, and ultimately, damage to the structure.

When drainage is not effectively managed, the excess water may also contribute to other problems such as mold growth, pest infestations, and landscape degradation. Observing standing water after rainfall or during wet conditions is a vital observation for a home inspector, as it signals a need for improvements in the property's drainage system to protect its integrity and longevity.

While cracks in the driveway, dirt erosion on slopes, and humidity in the basement can indicate various issues, they are not as directly associated with drainage problems as water pooling is. Cracks could signify other structural concerns, erosion might point to soil stability issues, and humidity typically relates to moisture control rather than external drainage. Thus, the presence of pooled water is the most relevant sign of inadequate drainage.
