We have had to call Prolux on two occasions, one where our front door handle broke off completely and once when the mechanism failed in the front door on our way out to leave to go on holiday, they came and fixed this within a few hours even running aroung trying to find the correct part so that we can get on the road in time!! I can honestly say we have never dealt with such a great company. Both times they have helped out on short notice and were very happy to do. The customer service is excellent and I know I would never go elsewhere for doors. Fantastic from start to finish. Thank you!

We had Glenn and Dan around our house to replace some window panes and locks. We were pleased with the great service and high quality work. We would use again in the future and would recommend to others.

Glenn did a fantastic job repairing hinges on my bathroom window and sorting out the locking mechanism on my kitchen door. Thank you for a very professional and friendly service. Much appreciated.

Gary and his team have installed a lovely set of patio doors for me. From being to end the service was perfect. Following this work we have had all windows priced for the entire house! Fair prices for quality products and excellent quality installation. I highly recommend Prolux for windows and doors. Looking forward to putting our next order in.
