We're working on a large refurb job,and the site manager is beyond fussy.Theres hundreds of m2 of skim to boards and all the window walls have been hacked off and new Windows fitted,the windows are 3 .5 m high.We started dabbing the Window walls today.He pulled us on the first two windows cos the margin on the window frame was 2mm out ,on a 3.5 high window,he said there's no such thing as a tolerance it needs to be spot on ,or he won't pass it......there's still 120 Windows to do Nightmare
