Unfortunately I discovered the blades only after a couple of different crews had been in (flooring, paint, and the remodelers), some had already been paid, and nobody was fessing up. It was pretty annoying because the workers would just not tell me of any problems or unusual things. I assume they didn't want to make me think they were responsible for the problem, but actually silence made me far more suspicious. We had a strong wind one day that blew something over and damaged it, and nobody said anything.
