Water is one of the biggest threats to a home’s foundation, and poor drainage can make the problem worse. When rainwater does not properly flow away from your house, it can collect around the foundation and create ongoing moisture problems.
Ideally, the soil around your home should slope away from the foundation. Gutters and downspouts should also direct roof runoff a safe distance away from the house. When these systems are not working properly, water can remain against the foundation for extended periods.
Over time, excess moisture can contribute to soil erosion and changes in soil conditions. In some situations, saturated soil can put additional pressure against foundation walls. Depending on the type of foundation and the severity of the problem, this may contribute to cracks, shifting, or other structural concerns.
Poor drainage can also increase the likelihood of water entering a basement or crawl space. Persistent moisture may contribute to damp conditions, unpleasant odors, and damage to materials stored in these areas.
Homeowners should regularly inspect gutters, downspouts, grading, and areas where water tends to collect after heavy rain. Keeping these drainage systems clear and functioning properly is a relatively simple way to help protect your home.
During a home inspection, drainage conditions around the property can provide important clues about potential moisture and foundation concerns. Addressing drainage problems early can help prevent small issues from becoming expensive repairs later.
