Step-by-step instructions to install a garage door in your house
Although there are several companies in your area that would install your garage door for you, there is so much satisfaction when you install it all by yourself. Installing your new garage door can be accomplished if you follow these ten steps that are listed below:
 Release the tension 
 You’ll need to release the tension in the torsion spring before you begin working on the garage door. Start by clamping adjacent locking pliers onto the torsion spring shaft and wedge the pliers in. Then insert the steel rod in the spring winding cone and loosen the set screws. 
 Disconnect the existing opener and door 
 After the tension has been released, you can disconnect the existing garage-door opener from the door.

 Install the door panels 
 You can now begin to install your new door. Drill pilot holes and secure the bar with screws. Attach the axle screws to the bottom and top of the panels. Place the panels in the door openings and fix. 
 Secure the hinges and install the track 
 Secure the top half of each hinge to the panel. You then need to attach the brackets. 
 Attach the spring assembly to the track 
 Attach the pieces to support the spring assembly and attach them to the track.
 Bolt the tracks together 
 Attach the horizontal track to the vertical track on the door and then bolt the tracks together. 
 Install the springs 
 First, attach the spring anchors to the spring, and then attach the spring locking cone. Bolt the two springs securely to the main header bracket. 
 Install the torsion rod and pulleys 
 Slide the torsion rods into the side header bracket. Secure the center header bracket to the center mark on the header. 
 Attach the cable 
 Attach the cable to the pulley wheel on both sides. Slide the wheel to the header bracket and secure. 
 Tighten the springs 
 Use the steel rods to tighten the springs on your new garage door.
