I have items in storage and the storage facility had some sandblasting done. As a result many of the units (including mine) had contents covered in sharp and fine grit from the sandblasting. This includes furniture and electronics that were not sealed in boxes. Can I request relief for damages due to negligence or do I have to go after the contracting company (or should that be the responsibility of the storage company)? I have insurance through the storage facility and already approached them but sandblasting is apparently not covered in the policy. Oh, and none of the residents were informed that sandblasting was going to take place. We weren't alerted to take precautions or anything.
