Garage Door Extension Springs in Montreal

Extension springs help lift and balance the garage door and are usually installed on both sides of the door, near the horizontal tracks. If one extension spring is broken or stretched, the door may become heavy, uneven or unsafe to operate.

Common signs of a broken extension spring

• The garage door feels very heavy
• One side of the door is lower than the other
• The door opens unevenly or gets stuck
• A spring on one side looks stretched, loose or broken
• The cable or pulley near the spring is loose or damaged
• The opener runs but the door does not lift properly

How to identify the right extension spring

Garage door extension springs are not chosen by door size alone. The correct extension spring depends on the garage door size, door weight, spring length, spring rating, pulley setup, cables and safety cable system.

To help identify the right extension spring, please send us:

• A photo of the full garage door from inside the garage
• A photo of the springs on both sides of the door
• A photo of the pulleys and cables near the springs
• A photo of the safety cables, if visible
• The garage door width and height, if you know it
• Whether the door is single-car or double-car size
• A photo of any label or sticker on the garage door, if available

Common residential garage door sizes include 8x7, 9x7, 10x7, 12x7, 14x7 and 16x7, but the spring must still match the actual door weight and system.
