I had one a few months ago where she complained about my brush was ruining and taken off paint,I did not clean them after they were painted but the rain must have loosened up some parts,anyway I showed her the brush I use for her house,it is very,very soft,she had her windows painted every year and obviously done again by a cowboy ,when I started on her first window I seen small flakes of paint running down the small panes and I will not do them any other way ,if I did them trad I will be there all day so I told her he did a rubbish job and I don't want to be responsable for damaging her paint work.
It can ruin the frames if there is dodgy paintwork,I refuse point blank to do some houses even trad as I am afraid they will cave in if I put a scrim to them,be careful because they will have you for new windows!
