Plumbing problems and leaks are among the most common sources of interior moisture that cause humidity in the basement. Leaky pipes, fixtures, toilets, and other plumbing can cause moisture in the house that drips down into the basement, creating dampness and wet spots.  Signs of a plumbing leak causing dampness in the basement include water stains and wet spots on the ceiling in the basement.  To inspect for leaks that you can't see, check your water meter reading and don’t use any water in the house for 2 hours. Check the reading again after 2 hours. If there's been a change, you have a leak somewhere that needs to be addressed. You may be able to address simple repairs yourself, such as changing a leaky washer, fixing a running toilet, or tightening a loose joint. For larger jobs, or if you don’t have much experience with plumbing maintenance, call in a professional to fix the leak. Steam from hot showers, baths, and cooking can also increase the humidity levels in your basement and throughout the house. Always run exhaust fans in the bathroom when bathing, and run the exhaust fan in the kitchen when cooking.  You can also reduce steam by covering pots with lids when you cook, and by taking cooler showers and baths. If you don’t have exhaust fans, open windows when you shower or cook. Your clothes dryer produces a great deal of moisture, because moisture evaporates from wet clothes as they dry. To prevent that wetness from ending up in your basement, install a vent if necessary to vent your dryer directly outside.  This is most likely a job that will require a professional, because you'll have to cut into the frame of your house to install the vent. The job will likely cost around $200 USD. Inspect hoses and ducts regularly for cracks and holes that could be causing leaks, and replace the duct or hose if you find signs of wear and tear. Ducts that carry warm and cold air around your house can also create humidity in the basement if there are leaks that allow moist air to seep out. If you suspect there's a leak in your ductwork, call in an HVAC expert for an inspection and repair. Many people use humidifiers around the house to make the air more comfortable, but this can lead to problems if you're already having trouble with moisture in the basement. To reduce humidity, don’t run humidifiers in the house, and especially not in the basement. To make air in the house less dry, turn down the temperature of the furnace. A dehumidifier isn't a permanent solution to moisture in the basement, but it will remove excess humidity while you fix the cause of the problem. Place the dehumidifier in the dampest part of the basement and turn it on. Depending on the size of your basement and the capacity of the appliance, you may need 2 dehumidifiers. Empty the dehumidifier reservoir whenever it becomes full, typically once every 2 days. This will prevent spills and keep the appliance working well. A hygrometer is a device that measures moisture in the air. You can buy them at most home and hardware stores. The ideal humidity level for a basement is below 50 percent. Anything over 80 percent is problematic, because that’s when mold and mildew will flourish. When the humidity level starts to rise, use the dehumidifier to control moisture while you address the cause.
