How do I make a door Threshold wider?

To make a door threshold wider, you can either replace the existing threshold with a wider one or extend it using wood or composite material. Measure the desired width and cut the new material accordingly, ensuring it fits snugly against the door frame. Secure the new threshold in place with adhesive or screws, and seal any gaps with caulk to prevent drafts and moisture. Finally, finish the surface to match the surrounding area if necessary.
