I want to make a new ope for a new window (or more technically a 'light' as I don't want it to open) in a really dark and dingy room that will hopefully brighten it up. I know the kind of Carlson window I need to align with the other there in the room already. But where will I find a builder who would do this kind of small job? Does anyone know a good and reliable builder to knock a hole in the wall make good once the window is installed? Perhaps Carlson do the whole service but I doubt it. Thanks for any advice and recommendations.
