Keep water away from your house with simple steps.
Check to make sure that water is properly drained away from your house. A good place to start would be to check the down pipes and gutters. They should be draining a few feet away from the house or into your underground drainage system. Make sure that there is no blockage or corroding occurring and check to see if they are connected properly.
After the winter examine to see if the grade of your driveway needs to be repaired so water does not collect near your house and seep into your basement. Make sure the walkways and soil around your house drain downhill avoiding unnecessary leaks.
If you have taken these precautionary steps and still have a leak issue contact a reliable and experienced renovator/ contractor, who will repair your drainage or foundation issue.
