How to Adjust a Garage Door Spring

Garage door springs offset the weight of the door and allow it to open and close with ease. A problem with the spring tension could cause the door to open or close unevenly, improperly, or at the wrong speed, and adjusting the springs will likely solve the problem. Garage doors come in different styles that use two different types of springs, and whether you’ve got an easy fix on your hands or a more difficult and dangerous task will depend on what style of door you have. You may be better off seeking the services of a professional if your door has torsion springs, especially if you don’t have the proper tools, have no experience, or lack a mechanical background.

Part One of Three:
Preparing for Your Adjustment Edit

Recognize side-mounted extension springs. There are two kinds of springs your garage door might use: side-mounted extension springs or torsion springs. Before you can adjust the spring on your garage door, you must determine what kind of springs your door has. Side-mounted springs are easier to adjust, while torsion springs are more dangerous to meddle with.

  • Side-mounted extension springs run above and parallel to the door track, and they’ll have an attached pulley and cable. [1] The cable, which holds the spring, attaches to hooks in the track hanger assembly. There will be two springs: one above each track on either side of the garage door.

Recognize torsion springs. Torsion springs are mounted above the door and will run along a metal shaft that’s parallel with the top of the door. This type of mechanism is usually used for doors that are over 10 feet wide. [2]

  • Lighter and smaller doors may only have a single torsion spring, while larger and heavier doors may have two springs, with one located on either side of the central plate.

Understand the problem. Improper spring tension can cause many problems with how your garage door opens and closes. The problem you’re having will help you figure out how you need to adjust the spring to fix the door. Doors that need spring adjustments may: [3]

  • Be difficult to open or close
  • Open or close too quickly
  • Not close fully or properly
  • Close unevenly and leave a gap.

Determine your solution. Depending on your problem, you will either need to increase or decrease the spring tension on the door. You will need to: [4]

  • Decrease the tension if your door isn’t closing fully, is difficult to close, or opens too quickly.
  • Increase the tension if the door is difficult to open or closes too quickly.
  • Adjust the tension on one side (where the gap is) if your door is closing evenly.

Assemble your tools. There are some basic tools and safety equipment you’ll need for this job. Your safety equipment includes gloves, safety glasses, and a hard hat. Your other tools are a sturdy ladder, a C-clamp, an adjustable wrench, and a marker or masking tape. If you are going to be adjusting torsion springs, you will also need two winding bars or solid steel rods.

  • The rods or bars should be 18 to 24 inches (45.7 to 61 cm) in length.
  • Solid steel bars can be purchased at hardware stores.
  • You will need to measure the diameter of the holes in the winding cone (the collar that secures the spring to the metal shaft) to determine what size bar or rod to use. Most cones have a hole diameter of 1/2 inch.
  • Do not attempt to use any sort of tool as a substitute for the winding bars or steel rods. [5]
