A lack of ventilation in the basement can cause moisture to collect in the air. It can also cause moisture in humid air to form condensation on the floors and walls. To fix the problem, ensure that the basement is properly ventilated. Air conditioning and heat exchange systems can be effective ventilation methods.

Water can also seep through porous materials in the foundation and collect as condensation on floors and walls. When the house is built on level ground or on ground sloping downward toward the house, it can cause water to seep into the home. Surrounding the house with soil that slopes away from the foundation can help fix the problem. Broken downspouts and gutters can also cause water to collect around the basement area; fixing them and ensuring that they drain properly can resolve the issue.

Poor drainage in the home can cause basement moisture or flooding. If the problem lies with the sump pit, install an exterior drainage system or adjust the interior drainage system so that it keeps the basement dry. If the problem lies with improperly drained heating ducts, make sure that all pipes are watertight and sufficiently insulated, and that they slope enough to let the water drain from the system.

Foundation cracks can cause leaky basement issues. To fix the issue, repair major cracks. To prevent cracks from forming in the future, make sure that the connections between the house and the foundation are in good shape.
