How to DIY it: Take off the loose bar by removing the screws on each of the posts that mount the bar to the wall. (If one side is solidly attached, leave it alone.) With the mounting plate now exposed, try tightening 
the screws in it. If that doesn’t work, remove it. Chances are you’ll find two plastic anchors underneath. Poke them with 
a screwdriver and let them fall inside the wall. Replace with bigger, stronger metal toggle 
anchors (above), sold at hardware stores. Just drive them into the existing holes with a drill 
or a screwdriver, and then re­attach everything.

How to DIY it: This job can be messy, so protect nearby surfaces by covering them with plastic or cardboard. Spray the springs with garage door lubricant (about 
$7 at home centers). Don’t use oil, grease, or other lubricants. They may be cheaper, or you may have them on hand already, but they won’t work as well and tend to pick up dust and grit—just what you don’t want on moving parts.
