If your garage door spring is broken or if your old door is damaged and worn, then you may want to have a new door installed rather than sink repair money into an old door. Garage door installation is usually a job that a professional should do because of the tension of the garage door spring. Here's a look at some of the steps involved in installing a new garage door.
Remove The Old Spring, Door, And Hardware
The first step in removing an old door is one of the most dangerous, and that's removing the spring. The tension has to be released from the spring so it can be dismantled. Once the spring has been released, the parts that hold it in place are taken down so the spring components are out of the way. Then, the door is removed from the track and carried away from the work area. Finally, the tracks are taken down. Even if the tracks seem to be in good shape, they will probably be removed so all new pieces can be installed at the same time. Once the entire garage door and its parts are removed, it's time to examine the frame to look for rotted and damaged wood that might need repairs so the frame can hold the new door securely.
Install The Door Sections
If you're having a sectional garage door installed, which is a popular option, the installation begins with preparing the bottom section by attaching the roller brackets and hinges. Then, the section is placed in the frame of the door, leveled, and temporarily secured in place. The same procedure is followed with each additional garage door section until the entire door is in place. However, starting with the addition of the second door section, the hinges between sections are attached so each section attaches to the other as more sections are added. It's important for the installer to keep the door level as it's built and to make sure it is square in the frame.
Install The Tracks, Rollers, And Spring
When the door sections are put together, the rollers are slipped into the brackets. Next, the temporary nails holding the door in place are removed so the track can be inserted along the side of the door. The track is added one side at a time and checked to make sure they are level and even before they're tightened in place. The hardware for the spring is added next. The last stage of a garage door installation is like the first stage in that it is one of the dangerous steps. When the spring is installed, it has to be tightened by turning it the right number of times. This places the spring under pressure, which is why it can be dangerous work.
When the spring is installed, the garage door is ready to use unless you want to add a new opener too. Before adding the opener, the installer will check the garage door to make sure it glides easily along the rollers and can be lifted without difficulty. It's also checked for slips since the door should hold its position when you let go of it. Adjustments are made if necessary, and when the job is done, your new garage door should last for several years as long as you maintain it properly.
