At Duration Windows we believe that the best way to make sure that every single one of our bifold doors leaves our factory in an excellent working order, is to check them thoroughly. Each bifold door that leaves our factory is checked by our Quality Control area and some of the checks are detailed below.

Once the doors have been checked and compared to the worksheet (shown in pic on left) it gets a green "PASS" stamp and is signed off by quality control.
Now that this door has passed quality control it will be wrapped up in several layers of bubble wrap and packing tape ready for delivery to our customer.
