Content insurance coverage problems?
Is your insurance contents coverage from your fire damage capped at a relatively low dollar amount and/or subject to depreciation with no replacement value cost feature?
If so, you may want to take the time in the first days of the cleaning and/or pack out to sort clothing and fabric items from the closets, etc. Folks often find, on the return of the cleaned clothes, etc. there are items which have not been used in years. These items often get donated in the end though.
Sorting these things right during the stress of beginning fire damage clean up and repair is a pain, but if contents coverage is a problem, it will save money to use on furniture, kitchen items, bedding, or heck, even new clothes.
