How to Replace a Garage Door Spring? | Essential Steps & Tips

: 18 March 2024

Think of garage door springs as muscles for your heavy door. They counter its weight, letting you open and close it smoothly, manually or with an opener. But like any muscle, these high-tension steel ones get tired over time and lose their lift. Replacing them keeps your door swinging smoothly.

While replacing these springs is possible for brave DIYers, caution is key! Springs under tension can be dangerous. Consider calling a pro unless you're a skilled (and very careful) handyman with the right safety gear and tools. Trust us, your safety is worth more than the DIY savings.

Remember: Professionals handle these tough guys safely and efficiently, keeping your garage door happy and your fingers safe.

What are the Various Types of Garage Door Springs?

Selecting the correct replacement springs for your garage door is crucial for safe and optimal operation. There are two main types used in residential homes: torsion and extension. Understanding their differences and matching them accurately is key.

Torsion Springs

Appearance: Heavy-duty, coiled springs mounted around a metal rod above the door opening.
