But, if keeping with theme how would it be explained that a house full of spirits would be able to maintain that well groomed look. No deserted mansion would have a ground crew would they? Or am I misreading your intent. It is really the same idea as the Tower of Terror. It's deserted, no one caring for it. Wild growth, dirty water lines, cobwebs and pretty much everything that one would expect to see in that situation. I remember being so impressed with the outside of the Tower, especially the fountain out front with the fake water line stain imply in that it once had water that evaporated away. Now that was attention to detail.
