for the window well full of water, 'tis very, very helpful to have LOTS of towels on handy. And a few buckets to catch the water in, or at least re-direct the falling water into via a towel. (That works well, by the way!) And if the previous residents of your home left a HUGE fan almost as tall as you and one of those commercial, yellow bucket mops with a ringer in the basement... well, you'll probably find out why sooner or later! =P
The only damage I believe, was to an empty cardboard box and the piece of carpeting we had under the computer desk. We saved everything else!
