A month ago all windows were replaced with nice new Rosewood windows . Ive now noticed marks on most frames as though they have been touched up . For instance most corner joints have a line and also various patches dotted around all over the place . The problem is its a completely different colour so when the light catches it it stands out and very noticeable from at least 5-10 meters away . So question is are these just marks from handling or construction that should be cleaned off at installation or has someone just gone mad with a dodgy touch up stick ??? Thanks
