I wonder how much he was being paid for this ?
I clean many sash windows from inside and it appears many on here hate cleaning from inside - customer having to be in, furniture in way etc. (they normally want double the price too).
In an ideal world, all sash style windows would open as they are meant to and be maintained but they are not, painted stuck, warped frames, broken sash cords etc.
If this guy could have cleaned it safely from inside as suggested, it would have taken him so much longer, would the hotel have paid that added expense ?
