Once removed, clean the area thoroughly to ensure a proper seal for the new threshold.Install the New ThresholdNow it’s time to install the new threshold. Measure the width of your door frame and cut the new threshold to size if necessary. Place the new threshold in position and make sure it aligns perfectly with the door. Secure it in place with screws, ensuring a tight fit. For extra protection against drafts and moisture, apply a bead of weatherproof caulk along the edges.Test the DoorOnce the new threshold is installed, it’s important to test the door to ensure it opens and closes smoothly. Check for any gaps and make adjustments as needed. Don’t forget to allow the caulk to cure fully for the best seal.ConclusionChanging the threshold on your exterior door is a simple yet effective way to improve your home's energy efficiency and curb appeal.
