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!
