There are three main causes of water damage: leaks, storms and flooding.
Leaks can occur for many reasons, but a common one is pipes or tanks freezing during the cold months. When a storm strikes, it can bring winds that weaken structural defences, with rain that then penetrates those defences. Particularly near to rivers and the sea, flooding can cause devastating damage that means a property can’t be used for a significant amount of time while it’s dried out and repaired.
