Thanks. Yes the springs are at the back of the door into the frame (look a bit like bike chain). There is no attached garage and all the doors are internal. Of course I won't disable them without the owner's permission and wouldn't want to invalidate insurance by contravening buildings regs.
I'm renting a modern terrace townhouse with 3 floors. All the internal doors have springs which make them shut on their own. I want to disconnect them to protect fingers etc but hear 2 separate versions of advice: Version 1 that Fire Regulations require spring doors in modern 3 floor...
