How can I replace the weather stripping on the bottom of a door?

To replace the weather stripping on the bottom of a door, first, measure the length needed and purchase the appropriate weather stripping material. Next, remove the old weather stripping by pulling it out or using a putty knife. Clean the area where the old stripping was removed. Then, cut the new weather stripping to the correct length and attach it to the bottom of the door using adhesive or screws. Make sure the stripping creates a tight seal to prevent drafts and energy loss.
