It's not that cheap, but you can get a Sawzall with a 9" metal cutting blade and it will go right through those like nothing.

There have been cases of idiots jumping on the bed or couch and losing an eye when they are struck by the swinging fan blade.

On windows, you might try just cutting them in by hand and if need be run paint an eigth or so onto glass and after a day or two go around with a new razor blade and clean it up.

Get a garden flat spade and scrape that stuff off, or go to box store and get a floor scraper with a blade to get up as much as you can.  

unbolt it from the floor or use a multitool with a good metal cutting blade to cut the bolts. sawzaw with metal cutting blade might do the trick too.

If you do have the black gooey tar mastic you need a diamond blade that spins to scrape it off.

The fan most likely needs to be balanced which is a simple process where you have to add little weights to some of the blades, this happens over time as the house settles so it can just pop up whenever.

I bought a few packs of sawzall pruning blades and a cheap electric chainsaw from Harbor Freight (After ripping the cord out of my trusty gas powered first thing that morning.)Me and my helper went to work.

I go to Harbor Freight for hand tools and blades. 

I pointed out to him that in the medicine cabinet, was a little slot where people of the time would literally drop their used razor blades right down into the wall.
