Hi, I have a drywall on the ceiling of my garage removed by PuroClean, a preferred vendor from my insurance. The contractor cut too deep in the I joists (7 joists continuously). I think they used recipient saw. I am concerning about the strength of the joists and the whole floor structure as above it, it's a kitchen, a high traffic area and two more stories. Any recommendations on fixing it? Any side effect of the incident such as void the joist warranty, reduce the house value or potential structure damage. Many thanks.
