Water or moisture in basements comes from two sources: indoor humidity that condenses on cold surfaces, much like water droplets form on a cold drink on a humid day. The other is water—or water vapor—that comes from outside. Rainwater, melting snow or groundwater can saturate the soil around your foundation and leak in through cracks, or it can penetrate porous concrete or masonry walls in the form of water vapor.
Get Rid of Excess Humidity
Eliminating sources of humid air will help dry out your basement. Seal leaky dryer vents with foil tape to prevent unwanted humid air from entering your basement. (Don’t just use duct tape; it’ll eventually fall off.) Add a vent fan to your basement bathroom and make sure your family turns it on during showers. Keep your basement windows closed during humid weather. And if you’re still getting condensation on cool surfaces, run a dehumidifier to lower the indoor humidity.
Condensation dripping from cold pipes can contribute to basement water problems. Cover cold water pipes with foam pipe insulation to stop condensation.
Insulate exterior walls to prevent condensation. In cold climates, insulating basement walls also saves energy and reduces your heating bill. However, don’t cover the walls with insulation if water is leaking in from outside; you’ll just create a potential mold problem.
Keep Water Away from the Foundation
If your basement leaks after heavy rains or after snow melts, making sure water is diverted away from your foundation may solve the problem. It’s common for the soil alongside your house to settle over time, creating a moat that collects runoff and directs it down your foundation wall and into the basement. Solve the problem by creating a 6-ft.-wide slope that drops about 4 in. away from the foundation.
Add Gutters and Extend Downspouts
If your basement leaks after it rains and you don’t have gutters, consider adding them. Gutters catch the rain and channel it to the downspouts, which direct it away from the house.
