We recently had Cor-Line Systems installation team install us aluminium patio doors which they designed to match our existing internal doors and what a fabulous job they have achieved, from start to finish it’s has truly been a pleasure to have them complete our install
Thank you to Graham / Harrison and the team
What a smoothness experience. Amazing sliding doors, quick turnaround and faboulous customer service. We will definitely be working with Cor-Line on future projects.
We recently had Cor-Line aluminium windows installed, and they are absolutely amazing! The quality is outstanding — no drafts at all, and they look so stylish and beautiful. We’ve previously used steel heritage windows, but there really is no comparison. The finish on the aluminium is far superior, and the heat performance is fantastic.
Even in the kitchen, there’s no trace of condensation, which has made a huge difference. On top of that, the customer service was brilliant from start to finish — friendly, professional, and always helpful. I honestly can’t recommend them highly enough!
I can highly recommend Cor-Line Systems, Harrison is great to deal with and makes things happen in a timely and professional manner.
We are a high end builder specialising in oak framed buildings and source all of our bifolds from Cor-Line, the technical department were happy to work with us to develop a way of installation that gives the forgiveness needed when fitting in to oak frames. Top Service
I can highly recommend Cor-Line Systems Ltd. From start to finish the team were friendly, professional and easy to work with. We had a quote we could work with and a date book in for install very quickly.
The installation team were clean and tidy and the job was done with minimal disruption to the day to day running of the school which always helps!
Thank you
We ordered 3 sets of Coroline windows, Graham was very helpful, quick to turn round quotes and the windows actually arrived earlier than expected. Stunning product and happily recommend
We bought a corner pair of cor vision sliding doors. Graham and Cor Line weren’t local to us but offer a nationwide service which worked really well. Graham gave us invaluable tips and advice in the design process of the extension regarding the doors which has resulted in a fabulous look and concept. The quality of the doors is fantastic and we were delighted with the whole process and service provided. We cannot recomend them highly enough. We will be getting some other new windows and doors and will definitely be repeat customers.
