Are you saying it takes 3 people to do two houses per day?
I've not done a huge amount of this work, but I've done about 20 builder's cleans, and it never took us that long. You pull all the window frame stickers off, soap up all the window, scrape it all with a four-inch scraper. Squeegy, and repeat one-or-two times more. Window clean, move to the next.
About two hours tops I'd say for inside and out for one person - and I still think that's stretching it.
Sometimes, if you can time it right, you can do it off their scaffolding; and on this particular estate I was paid within a week.
