They fitted a door and a window, the workmanship was inferior. Firstly removing the old door they were like toddlers with power tools after their efforts there was a gaping gap plaster falling after the wall and roof . Then the door was presented though a surveyor had measured twice, and the promise of a manufactured door to fit our door way. It was obvious they had fitted a too small a door with a window on top so there is at three four inches which they filled with insulation foam and messing up our main power cable did an amateurish work with plaster and render which leaked near my power cable so dangerous too. Customer service when faced with a complaint was they put the phone down, so please please do not buy from them do not rely they are a good and professional company they are an arrogant and shoddy outfit. we are now left picking up the pieces
