Should You Replace One Garage Door Spring or Both?

This is one of the most common questions. The short answer is that replacing both is often the better choice. Here is why.

Springs wear together

Two springs on a door are usually the same age. They have lifted the same weight the same number of times. If one breaks the other is close behind.

What happens if you replace one

The new spring is fresh. The old one is worn. They do not lift the same. The door may sit uneven. The old spring may break soon after. That means a second visit and a second bill.

When one spring is enough

Some doors have a single spring. Others may have had one spring replaced recently. A technician can check the age and condition of what is left.

What to ask

• How old is the remaining spring?
• Is it the same size and rating as the new one?
• What is the difference in price?
• What does the warranty cover?

The cost question

Two springs cost more than one. A second visit costs more than the extra spring. Ask for both options in writing and compare. Read what affects the cost of garage door spring repair.
