VIDEO all your belongings before! Check all work closely, especially inside closets or hidden areas for unfinished work.
Make sure all fixtures are similar to the ones removed & check for missing ones. VIDEO everything, large & small BEFORE anyone steps foot through your door. If belongings are removed from your premises, check everything against your video copy to make sure it's all back, before you sign that insurance check over.
Take every precaution before and avoid misunderstandings later. It's, also, a good idea to watch & be made aware of everything that's being thrown away without your knowledge or consent before the actual tearing out repairs begin.
