We recently had our aluminium bifold doors done by Klassic Trade Frames, and I’m happy with how they turned out. They’ve completely changed the space. It feels so much brighter and more open now, and they look clean and modern. The quality is great too; they feel solid and glide really smoothly.

Honestly, recommend Klassic Trade Frames to anyone. It’s hard to find people who care about the result as much as they do.

10/10!!! Ordered flush cream windows, a beautiful composite door and a 3-panel bifold. High quality, delivered quickly, and got us ready for the winter, improving energy efficiency and saving hundreds on the bills! Cannot fault the product, the service or the fitting.

Klassic Trade Frames supplied and fitted all my doors and windows as part of my house renovation. They were very accommodating and provided guidance throughout the process. They also supplied our bi-fold doors with the integrated blinds, which saved considerable costs. Some windows had integrated blinds, and others had opaque glass. Their assistance and expertise with the variations made the house look much more modern and enhanced its aesthetics.
