1. Stop any water from coming in through the foundation. This could mean cracks in the foundation, leakage around water and sewage pipes, tie-rod leaks, leaking bulkhead, and floor wall seams and cracks in the floor. This can all let water in.
2. Make sure the landscaping and soil around your home are pitched away from your house. You don't want your home sitting in water.
3. Take a look at the close dryer if it is in the basement. The dryer can let up to 1 1/2 gallons per load into the basement. Be sure the dryer vent is connected outside. You also want to be sure that pipe is somewhat insulated. The warm air of the dryer and the cool air of the basement can cause that pipe to sweat. You may also want to insulate cold water pipes in the basement.
4. Remove or put into an air tight container any objects that can retain water. This includes blankets, cardboard items and pillows.
5. Buy a dehumidifier. Some dehumidifiers can take out up to 150 pints per day. Some have pumps that automatically discharge the water outside.
6. The most common problem of all. Basement windows are often open, and they are open during humid weather. People think they are venting air outside, but actually this brings the humid air in.
