Water can seep into your basement through cracks in the walls or floor, but there are plenty of other places it can break through. Look for weak spots around your basement, such as mortar joints (spaces between bricks or concrete blocks) tie rods that reinforce masonry, the junctures where the walls meet the floor (known as a “cove joint”), the top of your home’s foundation, or window wells. Water can also come from leaky plumbing.
