What should I expect day 1 of the water damage restoration process?

On day one of a water damage restoration project, expect the focus to be on water removal.  Along with this, expect your project manager to perform a thorough inspection of the affected areas & completely document the process for record keeping/insurance purposes.  If you are planning to pay with insurance, your adjustor will receive an initial project report of cause/damages.  The insurance company is concerned with the cause and damages, not estimated costs.
