Last year , my home state was devastated by a flood the likes of which we had never seen (and we have survived some horrific hurricanes) but this was something totally else . The predominant factor that everyone had to deal with after was mold--everywhere and on everything from the walls to the furniture .
If you can get to the clothing and bedding in the first day, bring it to a washateria and wash in hot water and Pine Sol, then a regular wash cycle with detergent . Some you can save , some not . Real wood furniture can treated and cleaned with orange oil which most furniture companies sell or Amazon ! Any particle board is ruined . Throw it out . Any flooring besides tile is ruined. Rip it up and get it out of your home .
Lastly , don't throw away your treasured photos . Separate carefully and set out to dry. There were some incredibly gracious souls here last year (professional photographers ) that offered free restoration . I'm hoping someone steps up again .
My thoughts and prayers are with you all .
I didn't put a cost on this project because it wasn't a project and you cannot put a price on someone's entire life's belongings on the side of road .
