There are some steps that you can take to reduce the amount of moisture in your basement. Invest in a dehumidifier with a self-draining mechanism. Maintain gutters and downspouts, so they direct the collected rainwater away from the house foundation and walls. Leave the windows shut and replace old windows. If you have a sprinkler system, make sure the sprinklers are not pointed towards the house. This will over-saturate the soil causing water runoff, especially, if it rains as well. If these steps reduce the moisture but do not eliminate it, these steps will help with that. Install an interior drainage system with a sump pump. Install an exterior drainage system such as French drains, perimeter drains, and sump pumps. Install a vapor barrier, insulation, and air seal the basement walls. Seal foundation cracks. Grade the yard. If there are slopes that may point water in the direction of the house, this can keep water away from the foundation.
