I called Admiral for a service visit on my bi-fold doors that weren't closing properly. Ashton & Roy came and worked on the hinges to get the locks engaging properly, plus they adjusted the keep so that the traffic door doesn't rattle when it's latched. They're clearly proud of their workmanship and I'm glad I contacted Admiral - I happily recommend them and would use them again in the future.

The service and the speed of replying is amazing! I used Admiral Windows more then a year ago and the warranty on the windows had run out but they were ready to help and I solved my problem quite quickly.

As the tenant of a property, I am very satisfied with the services provided by Admiral Windows, arranged by our landlord. We had window panels replaced because of foggy glass, French window and regular window, all fitted perfectly and within good time. Highly recommended!

Admiral Windows provided a first class service from start to finish. The office staff and window fitters are very professional and I am more than happy with the windows. I would certainly use them again.
