That garage door that you use daily is likely one of the most valuable aspects you have in your home, even though it is often taken for granted until something goes wrong. As a homeowner, it is a good idea to understand some of the key components of the garage door you have in place. Doing so will make your life easier when you shop for replacement pieces or if you do ever have to seek professional garage door repair. Here are a few of the most typical garage door parts and their purpose.

Tension Springs- Without tension on the garage door, which can weigh between 300 and 400 pounds, it would be very difficult to close and open. The tension springs are located on the upper side of the garage door and create tension to force the door to close and open more smoothly.

Extension Cables - The extension cables support the weight of the door on either side when the door is in motion. These cables are made of thin, but strong steel metal cables. Over time, the steel cables can start to fray or even break, leaving you with needing professional help to get them replaced.

Astragal - This term is usually used to refer to the strip of rubber material that is connected at the base of the garage door for weather sealing purposes. It is not uncommon for the astragal to need replacement even on newer doors.

Curtain - If you are speaking with a professional and they mention the garage door curtain, they are speaking about the main panels of the door. The garage door curtain is the hinged surface of the door that moves to provide function.

Horizontal Track - The horizontal track is the metal beam that runs with the ceiling of the garage to support the main track and movement of the garage door. This track guides the door to open evenly, but can become soiled and in need of lubrication over time.

Top Header - The top header is located at the top opening of the garage door. This will only usually be visible when the door is completely closed and is responsible for keeping out rain, wind, and air.

Understanding a little more about the garage door you have in your home will make you a much more knowledgeable homeowner that can easier tackle finding help when something goes wrong. If you come across terms you are unfamiliar with when communicating with a professional, it is always a good idea to ask for clarification.
