When water is leaking into your basement, do you know where all of it came from? Water pipes often leak water, causing moisture to enter your basement. Cold water pipes should be insulated so that this problem can be avoided, and also to ensure that there are no problems or leaks in the plumbing.
Laundry rooms are also common in basements. Ensure that your washer and dryer are properly connected, and that the dryer vents air outdoors. Washers often leak, so confirm there are no leaks from it as well.
Often the cause of moisture in a basement may not be from the outside but rather through condensation and household appliances. Always be sure why and where moisture in your basement is permeating from.
