The first people you should call are water restoration companies like us. The sooner we get there, the less destruction there will be, which the insurance companies would prefer. You still want to call your insurance company to make a claim, but don't wait for them to arrive before you call a professional.
There are two major phases that are involved in the cleanup and repair from water damage. The first is the demolition and drying out of the damaged area, and the second is the repairing of the damaged area, which take roughly 3-4 days and a few days to a couple of weeks depending on the severity respectively.
Repairing your home after flood damage is more complex than it seems, depending on the severity of the damage, you need to do extensive repairs to your home so a professional is required. Floods can cause large mould growth which can be very toxic.
Mould mostly grows in warm, dark and moist areas, and can grow on many materials. It grows a lot when there is water damage, as the conditions are extremely moist and dark and it can cause major damage to your home.
