Tim & Mel Vary - Solarlux Cero II Sliding Doors - Harrogate
Sonia, David, Sharon and the whole team at Reveal were fantastic from start to finish, including helping us with deciding on the best configuration to suit our project and working with our architect and builders. We purchased Solarlux Cero II sliding doors from them and the installation team installed them with meticulous attention to detail. The doors are amazing, work beautifully and frame our view over the surrounding countryside and dale. The doors are a real feature in our renovation; the slim sightline enables an uninterrupted view and have a real wow factor. The contrast of the modern sliding doors and our renovated 17th century farm house and barn looks fantastic. We are very pleased with the end product and would not hesitate to highly recommend both Reveal and Solarlux.

Ed & Donna Curran - Solarlux Cero II Sliding Doors & Reveal Aluminium Doors & Windows - York
I would definitely recommend Reveal Doors & Windows. We initially met with Sharon at their showroom in Leeds who was extremely helpful and knowledgeable. The installation was straight forward and the follow up service has also been excellent.
