We have been longstanding customers of Prestige, starting off with replacement timber sash windows about 11 years ago. We subsequently replaced all our windows and then the front door. We finally decided to replace the back door once our cat died (no catflap required) and this was the most recent job. As usual, great attention to accuracy and detail - the door looks great and importantly is also energy efficient and secure. i would also say that when we did have a problem with some of the windows, Prestige were very quick to respond and handled things very well. I am a very satisfied customer.
