Clean water left standing for a couple of days can shift to Category 2, which changes what gets removed. That shift is exactly why a fast start matters.
Class matters just as much for the schedule. A Class 1 loss in one bathroom may dry in a couple of days, while Class 4 losses in hardwood, plaster or concrete need specialty setups and more time. Your restorer should spell out both ratings plainly and record them in the project file.
Keeping Three Parties Aligned
A good project lead updates the adjuster, chases phase approvals and gives you a realistic move-back date. Ask at the first visit who that person is and how often you will hear from them. If the answer is vague, that is worth noting.
