A continuous sag in your garage door is aggravating for any homeowner. Whether due to ageing, regular use, or faulty installation, a drooping garage door diminishes your home’s curb appeal and presents safety concerns. With the correct information and equipment, you often fix the problem independently, saving time and money.

Understanding the causes of a sagging garage door

1. Aging rollers and hinges – The rollers and hinges supporting the garage door wear out, resulting in the door sagging and becoming misaligned.
2. Unbalanced torsion springs – The torsion springs, which supply the required tension for lifting and lowering the garage door, become unbalanced or weaken, causing the door to sag.
3. Worn hardware – The screws, bolts, and other fasteners holding the garage door components in place loosen over time, contributing to door sagging.
4. Incorrect installation – If the garage door is not correctly installed, it is prone to sagging due to improper alignment or insufficient support.
5. Structural damage – In some cases, a sagging garage door results from underlying structural issues with the garage itself, such as a settling foundation or warping of the door frame.

Preparing to fix a sagging garage door

• Adjustable wrench or socket set
• Screwdriver set
• Pliers
• Tape measure
• Level
• Replacement rollers, hinges, or hardware (if needed)

Exercising caution when working on a garage door is crucial, as these systems are under significant tension and pose a safety risk. Contacting a Garage Door Repair Ashburn service is always best if you’re uncomfortable performing the repairs.

Step-by-step guide to fixing a sagging garage door

1. Inspect the rollers and hinges

Start by closely examining the rollers and hinges that support the garage door. Look for signs of wear, such as broken parts and loose or missing hardware. If the rollers or hinges are in poor condition, replace them with new, high-quality components.

2. Adjust the torsion springs

The torsion springs provide the necessary tension to lift the garage door. If these springs are out of balance, it causes the door to sag. To adjust the torsion springs:

• Carefully release the tension on the springs, following the manufacturer’s instructions.
• Use a wrench or socket set to adjust the springs, tightening or loosening them to restore the proper balance.
• Test the door’s operation to ensure it opens and closes smoothly without sagging.

3. Realign the door

If the garage door is still sagging after addressing the rollers, hinges, and hardware, the next step is to realign the door. It involves adjusting the door’s opener or manually repositioning it within the frame. Use a level to ensure the door is aligned correctly horizontally and vertically.

4. Check for structural issues

In some cases, a sagging garage door results from underlying structural problems with the garage itself. Inspect the door frame, walls, and foundation for any signs of damage or instability contributing to the sag. If you suspect structural issues, it’s best to consult a professional contractor to address the problem.

If you ever feel uncomfortable or unsure about tackling a garage door repair, it’s always best to call a professional for assistance.
