Here are 4 simple steps that will help you quickly and easily replace a door threshold.
Step 1 – Prepare before Buying Your New Threshold Strip


You'll find a large variety of thresholds on the market. Most are made of aluminum and may or may not have lips with some type of gasketing material that helps provide a seal for the door against weather.
Be sure to check the measurement of the threshold you purchase, to ensure that it matches the type you'll need to fill the gap between the door bottom edge and the floor beneath it. If you are unable to find a threshold long enough to match your opening, buy one that is longer, one you will be able to cut and fit to the opening.
Step 3 – Remove the Old Threshold
Locate the screws that attach the strip to the floor. If no screws are visible, and if you see a rubber or plastic strip in the center of the old thresold, use a flathead screwdriver to remove this strip. It's very likely that you'll find your screws in the channel the rubber strip occupied. Use your screwdriver to remove the screws that hold the old threshold to the floor.

Step 4 – Attach Your New Threshold
If you need to shorten your new threshold, carefully measure and mark it. Then, cut it to length. Check to see if holes in the new threshold are aligned with screw holes in the floor. If they're not, use your drill and bit to drill new holes that will line up with the new holes. Then, attach the threshold with new screws.
