“The front of our home looks totally different now, following installation of our new Endurance Composite door. Our home is also less drafty.
Communication by Great Harwood Windows was excellent, door was fitted on the scheduled date and time at the agreed price. Our home was left clean and tidy, old door was taken away. Excellent service, highly recommended.”
