How can water cause property damage?
When we think about flooding, big storms might come to mind first, but water damage can also start inside your home. Indoor issues often start with plumbing or appliances, while outdoor ones may be related to issues with the roof, gutters, foundation cracks, or flooding in nature.
Leaks, big or small, can gradually cause damage to your home including flooring, drywall, furniture and other personal belongings. Mould can also grow in damp areas in your home.4 Here are some of the most common causes of water damage.
Burst pipes
Pipes can burst and crack from wear and tear or freezing temperatures, causing water to leak into your home and damage walls, floors, and belongings.
Faulty appliances
Aging appliances or loose connections from dishwashers, washing machines, and refrigerators can cause water to pool causing damage to your property.
Roof and gutters
Clogged gutters or damaged roofs with missing shingles can allow water to seep into your home, causing damage to ceilings, walls, and insulation.
Sewer backup
Heavy rain can overwhelm sewer systems, causing wastewater to flow back into your home through drains and toilets, leading to contamination and damage.
River or lake overflow
When rivers or lakes overflow, water can flood nearby homes through doors, windows, and foundations, causing damage to floors and walls.
Extreme rainfall
Prolonged rain can seep into homes through roofs, windows, and foundations, especially if gutters are clogged, damaging walls and floors.
