If you have recently had a flood or a pipeline and your house has been damaged by water, you are probably wondering what's going on now? The first and most important step in water or flood damage is to stop active leaks in the house. This can be done by closing the main water supply to the house. If you do not know how to close your own water supply, call a professional plumber or your local water company for help. If active leaks are absorbed and all the water is removed, it is important to call in a professional to begin the water damage cleanup process as soon as possible to minimize damage.
