A dark, damp crawl space allows mold to flourish, which can then cause structural damage. Moisture dripping through the concrete foundation of your home can cause basement leaks. Air leakage into the section between the attic and the home can cause moisture on the underside of the roof, which can lead to mold and rotting. Check your home periodically, and look for light fixtures that are look as well as the overall quality of any noticeable piping.
To prevent water damage, you should replace your washing machine supply hose at least once every five years. Also, resist the temptation to overload your washing machine. Constantly stuffing too many clothes into your washing machine could loosen gaskets and valves or cause cracks. Take good care of your washing machine and your washing machine will take good care of you.
An insurance policy may or may not cover the costs associated with water damage and the process of water damage restoration. While a common cause of residential water damage is often the failure of a sump pump, many homeowner's insurance policies do not cover the associated costs without an addendum which adds to the monthly premium of the policy. Often the verbiage of this addendum is similar to "Sewer and Drain Coverage".
