Before You Begin

Replacing a garage door is difficult. The door is heavy and presents a danger if it falls on someone. The springs that act as a counter weight for the door are under great tension and therefore dangerous. If the old door has torsion springs which wind up around a rod at the head of the door, call a professional garage door installer to remove it because you have to release the tension in the spring and retension the new spring, which is dangerous if the spring gets loose.

Sound too complicated and time consuming? Here's a link to Home Advisor, a free referral service that matches homeowners with local door contractors.

  • Step 1 : Remove the old door

     Remove the old door

    Carefully follow the manufacturer's instructions to release the springs on the old door by raising the door fully to take most of the tension off the springs. Be very careful lowering the door since there will be no counter weight supporting the weight of the heavy door. Definitely don't do this alone, get help from someone.

    Remove the existing door from the track starting at the top unit. Unbolt the hinges in the center of the door and then remove the rollers from one side of the door. Lift the section up and off the hinges. Then move the roller-free side of the door into the garage to remove the roller from the track on the other side. Remove the other door sections in the same way.

  • Step 2 : Install door hardware

    Install door hardware

    Place the new door panels on a set of saw horses and follow the manufacturer's directions to attach the hardware to the door section beginning with the bottom door panel.
