Leaks can cause significant damage to your home and its contents. Water, in particular, is a common culprit behind water-related problems.

Here are some reasons why leaks can ruin your house:

• Water Damage**: Leaks can lead to water seeping into walls, ceilings, floors, and foundations, causing damage to the structure of your home. This can result in mold growth, rotting wood, and even electrical hazards.
• Nail Pointing and Cracking**: When water enters a wall through gaps around windows or doors, it can seep into the wall and cause nail pointing to become loose over time. If left unchecked, this can lead to cracking of the drywall and even collapse of the structure.
• Electrical Safety Concerns**: Standing water can create an ideal environment for electrical malfunctions. Water can short circuit wiring, leading to fires or electrical shock.
