At Garage Door Dimension, we repair and install all these essential parts that make your garage system work:

Torsion Spring
Balances the door’s weight for smooth lifting. Can break from wear, rust, or fatigue over time. Don’t risk serious injury—have a pro replace it safely.

Tube or Shaft
Holds torsion springs and transfers torque to lift the door. Can bend or warp from stress, causing imbalance or failure. Don’t ignore signs—have it checked by a pro.

End Bearing plates
Secure the shaft and carry door weight. Loose or damaged plates can lead to collapse or loud operation. Avoid costly repairs—get expert service on time.

Drums
Lift the door by winding cables. Wear, rust, or misalignment causes jerking or uneven movement. Stay safe—let a pro inspect and adjust as needed.

Cables
Lift the door by connecting bottom brackets to the drums. Can fray or snap from rust or tension. Don’t risk injury—call a pro for safe replacement.

Rollers
Guide the door along its track. Worn or broken rollers cause noise and jerky motion. Avoid damage — let a pro replace them for quiet operation.

Hinges
Join door panels and let them bend as the door moves. Loose or rusty hinges can jam or wear down the system. Tighten or replace for smooth performance.

Bottom Brackets
Secure lift cables at the base of the door. Damage or failure can cause cable release and injury. Stay safe—have a technician inspect and repair.

Tracks
Guide the rollers to keep the door aligned. Misaligned or bent tracks cause noisy or uneven movement. Don’t force it—call a pro to realign or repair it.

Panels
Make up the body of the door and protect your space. Dents or cracks weaken insulation and security. Don’t ignore damage—ask a pro about repair or replacement.

Operator bracket
Links the opener to the door for smooth travel. A loose or broken bracket can cause shaking or failure. Don’t let it slip—get a tech to tighten or replace it.

Center bracket
Supports the torsion system and holds it in place. Failure can lead to spring recoil and major risk. Don’t take a chance—let a pro install or secure it properly.

Strut
Reinforces door panels to prevent bending. Bowing doors may need added support. Don’t let panels warp—we’ll assess and install them if needed.

Opener
Powers your garage door automatically. Motor or gear issues cause stops, noise, or failure. Don’t get stuck—let our pros diagnose and fix it fast.

Slide lock
Secure your door manually for extra protection. Misalignment or wear prevents full locking. Don’t risk it—we’ll adjust or replace for guaranteed security.

Weather seal
Keeps out dust, drafts, and moisture. Cracked or worn seals reduce insulation. Don’t lose comfort—let us install a new one for better protection.

Sensors
Detect obstacles to prevent the door from closing. Dirty lenses or misalignment can cause failure. Don’t compromise safety — let us test and realign them.

Remote
Lets you open the door from your vehicle. Signal issues or dead batteries cause delays. Don’t get stuck—we’ll reprogram or replace as needed.

Wall Button
Mounted control for opening the door indoors. Wiring faults or power issues disrupt use. Don’t deal with flickers—our pros fix it fast and clean.

Keypad
Gives secure, keyless access to your garage. Fading buttons or glitches lead to lockouts. Don’t get locked out—we’ll reset or upgrade for smooth entry.
