New GRP front door and three uPVC windows at a property in Milton Keynes Quality of windows and door very good and better than others I had seen when obtaining quotations. Though this was reflected slightly in a higher cost but in my opinion worth it. Workmanship was good. Installers arrived after the agreed time which was inconvenient however the works were carried out efficiently and professionally Sales team were professional and very helpful. There was one issue with a mark on the door, which I assume was on it when it arrived from their supplier. Unicorn have made attempts to rectify this and it has been partially removed but remains a minor blemish on what is otherwise a very nice door.
