Had Crown Windows fit a bi-fold door and 2 patio doors when our extension was built 3 years ago and they have now replaced our front door and all windows in our house. Very happy with service and would definitely recommend them.

We had new windows throughout, French doors, Bi-Fold doors and a new front door from Crown Windows. Cheryll took us through the options available, advised in a friendly low pressure manner. Crown were very flexible with fitting around our building work. Very pleased with the service and would highly recommend.
