All insurance companies require the insured to mitigate or reduce a claim cost where possible. This may be as simple as turning off the water in a burst pipe situation to moving a valuable painting out of harms way where possible.
Professional restoration companies can help you with this by installing controls and salvage techniques, these companies expenses would normally be paid for by insurers. Renovation to a damaged building is everybody's goal but correct procedures must be followed if future damage and health risks are to be avoided. This is a simplified order of procedures:-
Identify Damaged Areas
Assess Hazard or Risk
Take Photographs
List damage & loss
Notify Insurer or Brokers
Salvage
