Just in case anyone is interested while we await an update from OP - some amusing 'workmen' stories.
Years ago I was having extensive work done on my house. Came home early one day and found a cat sitting on my microwave. I don't have a cat. Turns out they thought it was mine, had been letting it in every day, feeding it for me as they couldn't find any cat food in the cupboards!
Another time, different house, was having an extension built. My dog must have been annoying them and they'd shut it in the downstairs bathroom. My dog must have jumped up and knocked the lock. Cue, frantic phone call to me at work. I had to go home and give them permission to karate kick the door open, on the agreement that they'd do any repairs to the door.
Another time, different builders, managed to break 2 windows, one of which was a Victorian decorative pane. That cost them a pretty penny.
In every case, I'd have loved to have camera's set up so I could watch all the frantic goings on!!
