If water damage occurs in a home, there is no time to waste. You need to deal with the problem as quickly as possible. The reason is that if you let water buildup sit in your home for any length of time, the damage will spread and costly problems like mold can develop. This brings down the value of your property and most likely forces you to deal with the problem before anyone buys the home from you. So, when you discover water damage from a busted pipe, sump pump overflow, or some other kind of leak, the first thing to do is call a plumber and stop the leaking as soon as possible.
