A good composite door manufacturer will give you full instructions and a DIY DVD to walk you through the process, but the basics involve the following steps.
The first step
Measure your doorway with a suitable tape measure, making sure to measure inside the doorway. All composite door manufacturers require accurate measurements to ensure the door you order fits the room, and the best companies will offer advice or even a demo video on how to measure your door.
Second step
Once your door is shipped, make sure you have enough time to remove the existing door and install the new one.
Third step
Remove the existing front door and make sure you clean the rest thoroughly.
