Garage Door Installation
Types of Garage Doors
There are two main types of garage doors – those that operate by extension springs, and those that operate by torsion springs. Extension springs look like normal king-size springs and are located on the left and right sides of the garage door – you will see them stretch out and expand as the garage door lowers, and contract as the garage door opens. Torsion springs are the second type of garage springs — they look like tightly coiled springs above the garage door, and as the door lowers or raises, they twist to contract or expand.
Measurements before Installing Garage Doors
First the width and the height of the garage door opening is measured to determine the size of the door that you will need. Then the side room is measured on each side for installation of the vertical tracks. The area between the door opening and the ceiling (headroom) is measured as well. 10 inches headroom is required for standard garage door spring installation and 12 inches for torsion spring. More room is needed for garage door with an automatic opener. The final measurement is the backroom, which is the distance from the garage door opening, toward the back wall of the garage.
The wood framing around the opening is inspected by garage door installer. Any rotten wood must be replaced. Door tracks must be bolted to solid wood for successful garage door installations.
Before Garage Door Installation
All ropes and cords attached to the garage door are removed before installing a garage door. All garage door locks are deactivated. Lightweight fibreglass doors are reinforced to prevent any damage.
Garage Doors Installation
- Weather-stripping is attached to the bottom of the garage door.

- Hinges are attached to the second door panel.
- Second panel is set on top of the first one.
- Hinges are screwed to join the first door panel to the second one.
- Hinges and rollers are inserted into the track and attached to the second door panel.
- Third door panel is installed in the same fashion as the second one.
- Rest of the track is attached to the door frame.
- Top door panel is attached and secured with hinges.

- The garage door spring is hooked onto the door track bracket.
- Steel cable is fed over the pulleys at the end of the track. Cable is secured to the bracket.
- The garage door is tested to test the tension.
- Garage door opener is installed.
During overhead garage door installation the power unit has to be high enough, at least 7 inches from the floor. Door openers with a manual disconnect cord should be adjusted to approximately 6 inches from the floor, within reach for any adult.
