Frequently Asked Questions
What French door system do you install?
We install the Cortizo COR-70 aluminium French door system with 70mm profiles, multi-point locking, and PAS 24 certification. Every installation is FENSA registered with a CPA insurance-backed guarantee.
How much do aluminium French doors cost?
From around £1,800 to £4,000 installed, depending on size and specification.
French doors vs bifold doors?
French doors open outward on hinges — simpler operation and typically more affordable. Bifold doors fold to one side for wider openings.
Can I get French doors with sidelights?
Yes — we can add fixed sidelight panels either side to create wider, more dramatic openings.
