5 Things to Know Before You Replace a Garage Door Spring

Garage doors are a crucial home component, providing a secure space to store vehicles and other possessions. However, like any mechanical system, garage doors may experience malfunctions or breakdowns, resulting in inconvenience and safety concerns. The common problem with garage doors is the failure of the garage door springs. If you’re experiencing this issue, the following information can help you prepare for garage door replacement in Calgary or any other area where you live.

Important Things to Consider

Consider these points before your garage door repair and spring replacement.

1. Safety should be your priority

The first and foremost thing you should remember when replacing a garage door spring is safety. Garage door springs are under high tension and can lead to severe injury or even death if they snap. Therefore, it’s crucial to wear the proper safety gear, including gloves and eye protection, and ensure the area around the door is clear of any objects. Before starting the repair, unplug the garage door opener, and disconnect the power source to prevent any accidental opening or closing of the door.

2. Identify the type of spring

Before replacing the garage door spring, you must identify the type of spring your garage door uses. There are two types of garage door springs: torsion springs and extension springs. Torsion springs are above the garage door opening, while extension springs are positioned on the sides of the door. Knowing which type of spring you have is essential as they have different replacement procedures and require different tools.

3. Consider the door’s size and weight

The size and weight of your garage door are crucial factors to consider when replacing a garage door spring. These factors determine the spring’s size and strength, and using the wrong spring can cause the door to become unbalanced, leading to premature wear and tear. If you’re unsure about the size and weight of your door, consult a professional garage door repair technician.

4. Replace both springs

When one garage door spring breaks, it can be tempting only to replace the broken spring. However, it’s highly recommended that both springs be replaced simultaneously, even if only one is broken. This is because garage door springs typically have the same lifespan and experience the same amount of wear and tear. If one spring has failed, the other is likely close to breaking.

Replacing only one spring may cause an imbalance in the door’s weight distribution, leading to premature wear and tear on the new spring and potential damage to the garage door opener. Additionally, if the other spring fails shortly after the replacement, it will require another repair, resulting in additional expenses and inconvenience.

Therefore, replacing both springs simultaneously ensures your garage door operates smoothly and prevents future issues. By doing so, you’ll also save time and money on future repairs. If you’re unsure about the condition of your garage door springs or need assistance with the replacement process, contact a professional for garage door repair Calgary or another area where you live to get the job done safely and correctly.

5. Consider hiring a professional

Replacing a garage door spring can be a dangerous task. Hiring a professional is best if you lack the necessary skills and experience. Professional garage door repair technicians have the knowledge, tools, and equipment to safely and correctly replace your garage door springs safely and correctly. Attempting to do it yourself can lead to injury, damage to your property, or even death.


In conclusion, garage door spring replacement is a complex and potentially dangerous task that should be taken seriously. Safety should always be your top priority, and it’s essential to identify the type of spring, consider the door’s size and weight, replace both springs and hire a professional if necessary. If you’re facing any issues with your garage door springs repair in Calgary or any other area, don’t hesitate to contact an experienced garage door repair technician to get the job done safely and correctly.
