We would always recommend to do inside and outside for the best result , we clean all of the frames and the tracks surrounding each pane of glass. We ensure that every single piece of dirt , debris , paint etc is removed from the glass and will be crystal clear. Please remember when you have just had your windows cleaned as it is common that people walk straight into the glass they are so clean 🙂
We get to all those difficult places you would not normally be able to reach by using a purified water system ( which is a pole and brush that reaches up to 4 storeys from the ground .
With every clean we remove / clean and replace the fly screens . On occasions we remove the window on the sliding rail completely , clean the outsides ( from inside ) then re- install the window .
We also reach those awkward skylights you have always wondered how to clean .
