If they flap about, then the spring has broken that holds them in place. They are not expensive to replace but can be really tricky, after you have removed the handle assembly from the door, you have to put the spring under tension as you fit it. It takes a few goes and a bit of swearing, but it can be done!!
Is it worth doing them if you don't mind having to close it after you?
Doesn't sound like it!! Sounds like the sort of job that grows other jobs.
The chrome's not great on the handles anyway so perhaps I'll keep looking on e-bay for a replacement set.
Older and more confused than I could ever imagine possible.
My Traveller's door handles are a bit "floppy" but considering the work involved to remove them and replace pins and springs they're going to stay that way until I can either work up the enthusiasm or they fall off.
