Grosvenor Windows was first established 40 years ago as a small family business in the Bolton area and has grown to become one of the North West's leading home improvement companies still owned and operated by the same local family. The business was started by Peter Mills in 1975, initially as a manufacturer and installer of aluminium windows.
