New Garage Door Installation Guide
A garage door of more than 20 years would certainly need a replacement because newer doors are safer and not difficult to operate.
Below is a step-by-step guide on how to install a new garage door:
Before doing anything, the old garage door should be removed. This comprises mainly of unlatching the door from its pulley system, then dismantling the door panels and unscrewing the tracks. Ensure you remove each panel one at a time or else they could fall on you.
Step 1 – Release the tension
Before working on the garage door, you have to release the tension on the torsion spring. This can be done by clamping adjustable locking pliers on the torsion spring shaft and wedging pliers against the header wall above the door.
Insert a steel rod in one of the holes within the winding cone of the spring having 4 holes used for loosening and tightening. Hold the rod tightly then loosen its screws that hold the winding cone. Use the steel rods to loosen the spring just one-quarter each time then alternate two rods using one of them to hold the cone steady and the other to turn cone after the first one is removed.
Step 2 – Disconnect the Existing Opener and Door
After releasing the tension disconnected the garage door opener from the door. Then start removing the panels from the top panel and remove the hinges that are connected to the panel. Be mindful of the glass.
Unscrew or unbolt the track from the doorframe to disconnect it.
Step 3 – Install the door panels
You can start installing the new door. If it is a two-car garage door, a reinforcing bar should be placed on the panel to prevent the door from bowing in the middle. Make sure the bar is at the panel’s center then drill pilot holes and screw the bars.
Step 4 – Secure hinges and install the track
From the inside, secure the top half of each hinge to the panel then place the wheeled axles in the side hinges with the top and bottom axle supporting. Start installing the track by attaching the brackets to the vertical track pieces.
Step 5 – Attach the spring assembly to the track
Assemble the pieces that will support the spring assembly then attach them to the track. From the vertical piece installed earlier, rest the curved portion of the track on it. Then attach the other end to the ceiling bracket.
Step 6 – Bolt the track together
The horizontal track should be attached to the vertical track on the door but don’t tighten the bolts too firmly until the door fits properly and lines smoothly.
Step 7 – Install the Springs
Find the center of the opening and mark it on the header of the door. Then attach the support for the spring there afterward.
Step 8 – Install the torsion rod and pulleys
Slide the torsion rod into the holes in the side header brackets then secure the center header bracket to the center mark on the header.
Step 9 – Attach the cable
Bring up the cable from below, connect it to the pulley wheel on both sides then turn it so the slack gets pulled tightly from the door side. Next, slide the wheel to the header bracket and tighten it.
Step 10 – Tighten the springs
Use steel rods to tighten the spring by reversing the loosening procedure used on the old door. When getting to the appropriate tension, tighten the bolts in the anchor and lock it then remove your pliers from the torsion rod.
