Good to know

Everything you need to know

The Origin door has the quickest lead times in the industry.

Our lead times vary depending on the colour/appearance of your bifold door. This is the time it takes to have your bifold door installed from the moment you place your order.

  • White Doors: 3 weeks (possibly sooner if required)
  • Stock Colour Doors (Anthracite grey, black, black grey or slate grey): 3 weeks (possibly sooner if required)
  • RAL Colour Doors: 4-5 weeks
  • Dual Colour Doors: 6 weeks

All of our bifolds and windows are installed by our fully trained fitters, and installations are guaranteed for 10 years. If Bristol Bifold are installing your Origin bifold door, (which we do with the majority of our customers) then a site survey is included in the price.

Our team can discuss with your builders the heights of finished floor levels etc, and give them profile drawings of the doors.

We also take responsibility that the bifold door will fit on the day of installation.
