We purchased a front door from Fortis Aluminium in 2020 and were so delighted with the results that when we were looking to replace our garage door with a front door and picture windows we went straight back to Leanne and George. The customer service is very professional and friendly, the products are high quality and the fitting service is perfect too. We would thoroughly recommend them for their 5 star service!


What an amazing door! Complete bespoke 2.5m tall door, 1.1m wide, superb communication throughout and the delivery and install were done very smoothly and to a very high standard. Would not hesitate in recommending Fortis products. 1st Class!


Fortis Aluminium Ltd. Really helped me choosing the front doors. They went above and beyond in getting the measurements right and negotiating with the builders and getting the right colour and design as I wanted. I am so, so happy with Leanne and her team. The accuracy of “getting it right” attitude was always there.. I’m so happy with the Customer services and how each detail was discussed thoroughly. Thank you once again Leanne.


Thank you Leanne and Leon for the great service, great communication and ultimately an amazing new entrance for our self build... We love it!


Thank you for your installation of our new door. We were very impressed with your service and helpfulness the whole process from quotation to completion was faultless the installation was completed in one day with minimum disruption and the area was left in a clean and tidy condition we would have no hesitation in recommending your company to anyone requiring new doors.


My Wife & I would like to place on record our thanks for your help in choosing, supplying and installing our new front door at our property.
It was a pleasure to deal with you and your team, and we are delighted with the result - a dramatic improvement, which we would be happy to recommend to anyone! Thanks once again


I would like to thank you for the good job you did on my entrance.. This was the second time we have used your services and we are totally satisfied and would not hesitate to recommend you to others.
The work men arrived on time and cleaned up after the job each day. I am very satisfied with the completed job.


Excellent experience from start to finish. Professional, knowledgeable and enthusiastic, with a great range of products and experience to help guide you. We purchased a new Fortis Aluminium front door as well as a garage door and the process was flawless and completely problem free. Special thanks to Leanne who was fantastic from the start and throughout the process, as well as the installer, Leon, who again knew exactly what he was doing, explained everything and overcame any issues with a practical solution. We couldn't recommend these highly enough!


CMS Doors - now Fortis Aluminium, excellent company to deal with from start to finish.

I cannot recommend CMS - now Fortis highly enough. We recently had our front and garage door replaced by them. They have a superb showroom, with lots of choices and options. Very experienced staff on hand to answer any questions. Fortistook care of coming out to check measurements to full installation. Excellent service from start to finish!


Fortis have proven to be the BEST choice within the UK market. From visiting first their Showroom that have an impressive exhibition of different types of doors, colours and finishing products the quality is outstanding to the higher standards in the door industry. The process of Design, Procurement, Manufacture and Installation was managed by Fortis. Brilliant so as customer you always have the attention to detail required on the product chosen. Many thanks again for the installation successful completed.
