Big crash

Around 10pm we heard a big crash as if something heavy had fallen on the floor.  The problem was, we couldn't find anything that had fallen.  The next morning we discovered what had happened.  Part of the decorative masonry on a second story window fell off, crashed into the window below and ended up on the ground.  The landlord sent people to make repairs which turned out to be an extremely long and dusty proposition.  First they chipped off the damaged pieces, then to prevent another incident, they drilled holes in every piece of remaining trim all over the house and screwed them into the structure.  Then they filled the holes and sanded them smooth which send tons of dust into the house.  The badly damaged pieces are being copied and there will be more dust when those finally get installed.
