    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.
