Spring rains can bring many pains.
Here in Southwest Michigan we get some very heavy spring rains. They usually come with powerful winds resulting in power outages. This combination results in many flooded basements. Wind driven rain can enter your home under shingles. Trees can fall on your roof letting water in. Gutters clogged with leaves and sticks can overflow water against your foundation. Clear them out and drain 5 foot away from home. Hydrostatic pressure can push water through foundation walls. When power is lost your sump pump stops working and the basement floods. *Check to see if you have a sump pump rider on your homeowners insurance policy. If you don't the water damage may not be a covered loss.*
Are your drain lines clear of roots and debris so water can move to sewer? If not you could experience backups.
