Frequently Asked Questions

What French door system do you install?

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.

What guarantees do you offer?

Cortizo Cor 70 Hidden Sash and Schuco AWS 70.HI French door systems include a 10-year manufacturer warranty covering the powder-coat finish, hinges, multi-point locks and thermal break integrity. Installation is FENSA registered to confirm compliance with Building Regulations Part L (thermal) and Part Q (security), and we add a 10-year CPA insurance-backed guarantee on the fitting work itself.
