I don't.
I think they're untidy, even if they don't. I like to be in too so I can see what bodges they're going to try and sneak past me.
I keep having to tell them to watch this, watch that, clean this up, don't leave it like that. I gave the window fitters a brush to clean the mess up they kept leaving around the garden
the excuse of tidying up when they've finished is rubbish, bits tread in and blow all over the place.
they don't get a cuppa unless they're tidying up as they go. I even gave the workmen next door a bollocking for dropping stuff and letting it blow around my garden, "we were going to pick it up when we'd finished", yeah right
I have to be spotless at work, if I can manage it so can they
on the plus side its raining so I'm not on the roof today
however, apparently the doors etc. are inside where it's dry
