I was offered a School (guy I know is the head Caretaker). It was way too big for me in the end, but I did price it.
Break the school down into loads of sections and work out how long each individual section will take.
Make sure you see EVERYTHING.
Allow time for access to awkward windows and windows above flat roofs etc.
Allow for doors and canopies etc.
Ask if there are any other bits that need cleaning.
Add up all the hours and add 20%. Now you can work out a price.
Check how they will pay and how long the payment will be.
I ended up with pages of notes.
Also check for an outside tap or taps. I ended up giving this job to a friend of mine who only does commercial stuff (he does this stuff in his sleep and re-priced it himself). The windows hadn't been cleaned in years and were minging.
He ended up using the schools tap to clean the windows with one of his lads following behind him, finishing them with pure.
He did a really good job and got another School out of it.
Actually, he still owes me a beer
