This depends on a large number of factors including how widespread the flood was, how severe the damage caused was, and how many properties were affected is the first variable. After a major flood event, insurance companies often take on additional loss adjusters, but even so the time it can take for you to be visited by one can be longer than you’d like.
Cleaning and drying operations can take many weeks or months depending on the availability of services and how greatly your property has been affected, as well as what your home is made of.
Finally, reinstatement works themselves are also time-consuming. The process of choosing replacement furniture, decoration and fitted units (which you may have originally selected over the course of years) takes time, especially if you are working and have little time to shop around, and then you need to wait for delivery and fitting.
