I am a general contractor currently working on a 203k and insurance claim . To date the client has paid us 10,494.00 with a pending payment that has been deposited in my account and pending if $1755. We recently started a back porch roof repair on our SOW, and found damages outside of our SOW. We tried to tarp the area off as best as possible however the tarp blew up in the front which caused damages to her ceiling in the office , we offered to replace and proceed with additional repairs as well as do the work needed to properly do the job we need to do .. I am afraid customer is going to try and not pay me , and feels I’m at her mercy .. What should I do
