We had our windows and front door completed by Bedford Bi-Folds. Allan came out originally to quote, he was very informative advising us of all options. We were kept up to date with when the install would take place. The install team were brilliant, friendly, efficient and left everywhere tidy. The windows and door look amazing, we are so pleased, thank you for such a brilliant service and end result. Would definitely recommend.

Thanks to all at Bedford Bi-Folds for a professional and pleasurable experience from start to finish with the installation of our Bi-Folds and window. Kev and Archire above and beyond expectations coming at 5pm to fit these. Will be using them again when our on going project picks up pace, would highly recommend using Bedford Bi- Folds if anyone is looking for doors, windows etc etc, Kev listened to what we wanted and produced exactly that.
