Side-Mount vs. Overhead Garage Door Openers: Which is Best for Your Home?

When you decide to upgrade your garage, the motor (the opener) is the most important choice you will make. Most people are used to the big motor hanging from the ceiling, but there is another option that is becoming very popular in British Columbia: the Side-Mount (or Jackshaft) opener.

At Lions Gate Garage Doors, we want to help you pick the right tool for the job. This guide compares the classic overhead style with the modern side-mount style so you can decide which fits your lifestyle.

What is the difference between Side-Mount and Overhead openers?

The main difference is where the motor is installed. Overhead openers sit on a rail in the center of the ceiling and use a belt or chain to pull the door. Side-mount (Jackshaft) openers are installed on the wall beside the garage door and turn the torsion bar directly to lift the door.

• Choose Overhead if you want a budget-friendly, reliable option for a standard garage.
• Choose Side-Mount if you have high ceilings, want to save overhead storage space, or have a room above the garage that needs to stay quiet.

1. The Overhead Opener: The Traditional Standard

If you look into most garages in Surrey or Burnaby, you will see an overhead opener. These have been the standard for decades.

How they work:

An overhead opener uses a long metal rail. Inside that rail is a chain or a rubber belt. When you press the button, the motor pulls the door along that rail.

The Pros:

• Affordability: These are generally the most budget-friendly options.
• Variety: You can choose between loud, strong chain drives or whisper-quiet belt drives.
• Reliability: They are very simple machines that last a long time.

The Cons:

• Takes up Space: The rail and motor hang down from the ceiling. This can get in the way if you have a tall truck or want to hang bikes from the roof.
• Vibration: Because they are bolted to the ceiling joists, you can often feel the vibration in the room directly above the garage.

2. The Side-Mount (Jackshaft) Opener: The Modern Solution

Side-mount openers, like the popular LiftMaster 8500W, are changing the way we use our garages. Instead of sitting on the ceiling, these sleek boxes mount on the wall to the left or right of your garage door.

How they work:

These openers connect directly to the door's "torsion bar" (the metal rod above your door). Instead of pulling the door back along a rail, they simply spin the rod to lift the door up. You can learn more about the mechanics in our blog on how garage door openers work.

The Pros:

• Saves Ceiling Space: Your ceiling stays completely clear. This is perfect for people in North Vancouver who want to use their garage for a home gym or extra storage.
• Ultra-Quiet: Since it isn't attached to the ceiling joists, there is almost zero vibration sent into the house.
• High-Lift Ready: If your garage has very high ceilings, a side-mount is often the only way to go.
• Advanced Features: Most side-mounts, such as the LiftMaster 98032, come standard with Wi-Fi, battery backups, and automatic deadbolts.

The Cons:

• Price: They are more expensive than standard overhead models.
• Requirements: You must have a "torsion spring" system. If your door uses old-fashioned "extension springs" on the sides, a side-mount won't work without an upgrade.

Which One Should You Choose?

Choose an Overhead Opener if:

• You want the most "bang for your buck."
• You have a standard-sized garage with a normal ceiling height.
• You don't plan on using your ceiling for storage.

Choose a Side-Mount Opener if:

• You want to park a tall vehicle or a boat.
• You want to turn your garage into a "man cave," workshop, or gym.
• You have a bedroom above the garage and want the quietest operation possible.
• You live in a modern home and want the latest LiftMaster technology.

Professional Installation Matters

No matter which style you choose, the opener is only as good as the installation. A side-mount opener, in particular, requires very precise calibration to ensure the door stays balanced.

If your door is heavy or hard to move by hand, it might have a broken spring. We recommend having a professional check your door’s balance before installing a new motor.
