How Garage Door Installation Works

Garage Door Installation

Are you considering garage door installation as a DIY weekend project?

You might be able to do it if you’re handy, but keep in mind that it might affect your warranty. Manufacturers’ warranties cover parts and workmanship, and installation warranties cover labor, but if you do the installation yourself and it’s not in accordance with the manufacturer’s guidelines, you may void the warranty.

To complicate matters, what may look like an easy garage door installation job can be a hazard in disguise. You want to ensure your garage doors function properly — safety is a priority when loved ones are pulling into or out of the garage.

If you tackle the job yourself, you must first understand the ins and outs of garage door installation.

When removing the old doors, always follow the manufacturer’s instructions. Usually, it’s unlatching the doors from a pulley, removing the panels and unscrewing tracks. Panels must be removed one at a time, otherwise they can collapse like dominoes.

A Numbers Game

Areas around the door need to be measured to gauge headroom and back room. Headroom is dictated by the spring system, and should be about 11 inches. Back room requires 18 inches at minimum, in addition to the door height.

Once measurements are made, stops are temporarily connected to the opening’s sides. They should sit flush with the doorjamb’s inside edges. Next, set the door up on sawhorses and prep the bottom with weatherstripping. You can attach handles and hinges at this time if they aren’t already on.

Next, put the bottom piece of the door in place by setting it into the door frame. Use a level to make sure it’s aligned correctly. Drive nails securely into jambs. Assembly of horizontal, vertical or curved pieces vary by manufacturer.

The second row of panels is placed on top of the first, and again, nailed into the side jambs and anchored into the door jambs.

Finishing Touches

Next, put the rollers in the track, making sure the brackets are secure. If the rollers are too tight in the track, it can damage the doors. Vertical tracks are placed first, followed by curved and horizontal. For horizontal pieces, check that they are facing away from openings at exactly 90 degrees.

The last step is the spring assembly, which also varies by manufacturer. You need at least two people to pick up the door halfway to check that the tracks are parallel before you can open the door completely and connect the springs to the pulley system.

As you can see, this is a big and strenuous job that can take the average homeowner a lot of time, sweat and energy to complete. For best results and guaranteed quality, contact Garage Door Man for all your garage door installation needs.
