Causes of floods: In the US, the leading cause of water damage to the basement is often due to the failure of the sump pump. A sump pump drains water that accumulates in the sump pit. If the sump pump's failure isn't the reason, other possible culprits could be a broken water pipe, a failed water heater, or valves leading to outdoor pool lines or sprinkler systems that haven't been shut off. Though not very common, flooding caused by natural disasters extends the most extensive water damage to the basement and the whole home over the others.



Play it safe when in flood: It's always best to be on the safe side when your basement is flooded - you should never step into a flooded basement. Always look around to see if there are any electrical appliances plugged in. If possible, switch off the main power supply that feeds the whole house before inspecting.

If your home is prone to flooding, it's a good idea to keep any expensive items, appliances, and furniture away from the basement to prevent costly water damage. Heating and cooling systems should be mounted on walls or installed in upper levels. If you feel it's a waste of basement space, home furnishings and appliances could be placed on platforms or blocks that raise them from the floor and keep them a safe distance from floodwater should flooding occur.

Invest in flood insurance: Though it is an added cost, investing in flood insurance is a good option. Water damage caused a flooded basement can easily deplete your savings even if it occurs just once. Check if your community is one of the 19,000 in the US under the National Flood Insurance Program (NFIP).

Predict the future: Before purchasing or building a house, here are a number of things you can check out in advance to avoid future water damage. It's wise to check the flood risk status of the surrounding area - not only yours. If your house lies on a slope of 2% or more it will draw water down the slope and away from your house so this is a good thing. If you are purchasing, inspect the basement to see if there are any water level markings on the walls. Check out the edges of the floor for signs of moisture. Recent signs of even minor water damage can indicate flooding.

Observe and be alert: Last and the most important advice - always keep alert. Be on the lookout for any cracks and holes in the floor and walls. To guard against water damage, waterproof your basement by applying a waterproofing coat. If you can afford it, have a sump pump installed. Clean and keep your drains free from debris. Always maintain your home and don't make carelessness the reason for water damage woes.
