Question

How do I replace 2 broken hinges on exterior door of my static caravan.

Answer

These hinges are usually screwed to the door and riveted to the frame, if you need to replace the complete hinge you will need to drill out the pop rivets and rivet the new hinges to the frame using a rivet gun. If you do not have this tool it is quite cheap and can be purchased at any DIY or hardware store.
