How to Replace an Aluminum Door Threshold
Replacing an aluminum door threshold is a quick and easy way to keep your energy bills down. The threshold helps prevent outside air from seeping under the door, and your heat or air-conditioning from escaping. In addition, thresholds form a barrier to avoid giving insects a clear path into your house. Aluminum lasts longer than traditional wooden thresholds, and it is easier to clean and maintain.

Tips & Warnings
Aluminum thresholds bend easily, and too much pressure can make them break. Always dry-fit all parts before the final installation.
Use caution with aluminum, which can be very sharp. Work gloves can be worn to prevent injury.
