Garage Door INSTALLATION Process

We start with an on-site assessment, then handle everything from site prep to mounting tracks, balancing springs, and installing operators, whether it’s a residential garage door installation or commercial garage door sales project. Before work begins, we provide a clear garage door installation cost estimate, and once your overhead garage door or industrial garage door is in place, we test it under load to make sure everything runs smoothly.

1. Measure the Opening

Pre-installation Measurement: We take accurate measurements of the garage door opening (width, height, headroom, and backroom). The backroom should have enough space to accommodate the door when fully open.

2. Prepare the Workspace

Clear the Area: We’ll help make sure the garage is cleared of any obstructions.
Inspect the Existing Frame: We ensure the door frame is in good condition and capable of supporting the new door.

3. Assemble the Door Panels

Lay Out the Door Sections: If we’re installing a sectional door, we lay the door sections flat on the garage floor. We check that each section is in the correct order from bottom to top.
Attach Hinges and Handles: We install the hinges between the sections and attach the handle to the bottom panel, which helps in the lifting process.

4. Install the Panels

Position the Panel Sections: We place the bottom section of the garage door in the opening, using shims or blocks to ensure it is level, as this will affect the entire installation.
Secure Each Section: We fasten the hinges to the door jamb using lag screws. This secures the bottom section in place.
Install Rollers: As we stack the sections, we will insert the rollers into the hinges at the sides of the door.

5. Attach the Tracks

Vertical Tracks: We attach the vertical tracks to the door frame. The rollers should slide into these tracks as you lift the door sections. We’ll make sure they are perfectly vertical using a level.
Horizontal Tracks: Our team will install the curved horizontal tracks that guide the door as it moves from vertical to horizontal. These should be securely attached to the garage ceiling, typically supported by angle brackets.

6. Install the Torsion Spring System

Assemble the Spring Components: The torsion spring system helps balance the door and provides lifting power. We will install the springs above the door on the header.
Wind the Springs: This is a critical and potentially dangerous step! The springs must be wound tightly according to the manufacturer’s specifications to ensure the door operates smoothly. Our teams’ professional expertise is key for avoiding improper handling that can lead to injury.

7. Install the Garage Door Opener

If we’re adding a garage door opener, we mount the motor unit to the ceiling.
Connect the Opener Arm: We’ll attach the opener’s arm to the door and adjust the travel limits to ensure it opens and closes fully without hitting the floor or ceiling.

8. Adjust and Test the Door

Check the Door Balance: At this point, we’ll disconnect the garage door opener and manually lift the door halfway. If the door stays in place, it is balanced correctly. If it moves, the springs may need adjustment.
Test the Door’s Operation: Now we’ll reconnect the garage door opener and test the door for smooth operation. It should open and close without resistance and stop if the safety sensors detect an obstacle.

9. Final Adjustments and Lubrication

Tighten Hardware: Our team will ensure all bolts, screws, and brackets are tightened securely.
Lubricate Moving Parts: We apply a lubricant to the springs, rollers, and tracks to reduce friction and noise.

10. Final Inspection

Check for Smooth Operation: We will open and close the door multiple times to ensure smooth operation. Then we can verify the door’s alignment and make any final adjustments to the springs, tracks, or opener
