How to Replace a Garage Door Spring and Why You Should Hire a Professional

Jul 17, 2026

Your garage door relies on several hardworking components to open and close smoothly, but few are as important as the springs. These tightly wound pieces of hardware counterbalance the weight of the door, making it possible to lift hundreds of pounds with minimal effort. When a garage door spring breaks, many homeowners search online for instructions on how to replace it themselves. While DIY projects can save money in some situations, replacing a garage door spring is not one of them.

Here’s what you should know about garage door spring replacement and why it’s a job that’s best left to trained professionals.

Understanding Garage Door Springs

Most residential garage doors use one of two types of springs: torsion springs or extension springs. Torsion springs are mounted above the garage door opening and use torque to lift the door. Extension springs are installed along the sides of the door and stretch as the door moves.

Both types are designed to handle an incredible amount of tension. That tension is what allows the springs to support the weight of the garage door, but it is also what makes them dangerous to repair or replace without the proper tools and experience.

What Happens When a Spring Breaks?

A broken garage door spring can leave your door difficult or impossible to open. You may notice several warning signs before complete failure, including:

  • A loud bang coming from the garage
  • A garage door that won’t open or only lifts a few inches
  • Crooked or uneven door movement
  • Visible gaps in the spring
  • The garage door feeling much heavier than usual

If you suspect a broken spring, stop using the door immediately. Continuing to operate it can damage the opener and other garage door components.

Can You Replace a Garage Door Spring Yourself?

Technically, there are DIY guides available online that explain how to replace garage door springs. However, simply following instructions does not eliminate the risks involved.

Replacing a garage door spring requires specialized winding bars, proper safety procedures, and a complete understanding of how the spring system works. Using the wrong tools or making a small mistake while releasing or applying spring tension can result in serious injuries or significant property damage.

In addition, choosing the wrong replacement spring can affect your garage door’s balance and shorten the lifespan of both the springs and the opener.

Why Professional Garage Door Spring Replacement Is the Safer Choice

Hiring an experienced garage door technician offers several important advantages.

Safety Comes First

Garage door springs are under extreme tension. Professional technicians have the equipment and training needed to safely remove broken springs and install new ones without putting themselves or your home at unnecessary risk.

Proper Spring Selection

Not all garage door springs are the same. Professionals calculate the correct spring size based on your garage door’s weight, dimensions, and design to ensure smooth, reliable operation.

Complete System Inspection

A broken spring may not be the only issue affecting your garage door. During a spring replacement, a technician can inspect cables, rollers, hinges, tracks, and the opener to identify worn parts before they lead to bigger problems.

Long-Lasting Results

Professional installation helps ensure your new springs are properly balanced and adjusted, reducing wear on the entire garage door system and helping your investment last longer.

Don’t Ignore a Broken Garage Door Spring

A broken garage door spring is more than an inconvenience. It can quickly become a safety hazard if handled improperly. Rather than risking injury or causing additional damage, trust an experienced garage door company to complete the repair safely and efficiently.

Professional service gives you peace of mind that your garage door is operating correctly and helps restore reliable access to your home as quickly as possible.
