Modern dark grey front doors with silver handle

I recently purchased two doors, and I couldn’t be more satisfied with the quality and overall experience. The materials feel durable and well-crafted, with a solid, premium finish that I’m extremely happy with this purchase.

Blue front door with decorative panels and top window, set against white panelled wall with nearby hooks and a partially visible bench.

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. Will be returning for the garage door and outbuildings.

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. Their assistance and expertise with the variations made the house look much more modern and enhanced its aesthetics.
