Dos for Adjusting Garage Door Springs

Adjusting garage door springs is a task that requires careful attention to detail and a thorough understanding of the mechanisms involved. Mishandling of garage door springs can lead to serious injuries or property damage. To ensure safety and effectiveness, it’s essential to follow a set of dos when adjusting these springs.

Understand the Type of Springs

Before attempting any adjustments, it’s crucial to understand the type of springs your garage door operates with. There are two primary types: torsion springs and extension springs. Torsion springs are mounted above the garage door and wind up as the door closes. Extension springs are typically mounted on either side of the door and stretch as the door closes. Knowing which type of spring system your garage door uses will help you make informed decisions and adjustments.

Torsion springs are considered to be safer and more durable than extension springs, but both types require careful handling during adjustment. Understanding the specific characteristics and operation of your garage door springs will allow you to proceed with the necessary caution and expertise.

Use Proper Tools and Safety Equipment

Working on garage door springs involves dealing with high tension and potential hazards. Therefore, it’s essential to use the proper tools and safety equipment to minimize risks. Safety glasses, gloves, and sturdy footwear are essential protective gear when working on garage doors. Additionally, specific tools such as winding bars, vice grips, and a ladder may be required for adjusting the springs safely.

Using the correct tools not only ensures your safety but also facilitates a more efficient and precise adjustment process. Attempting to improvise with inadequate tools can lead to accidents or damage to the garage door system.

Release Tension Safely

Before making any adjustments to the springs, it’s crucial to release the tension safely. This involves opening the garage door fully and clamping locking pliers onto the track below the bottom roller to prevent the door from moving. By releasing the tension in the springs, you reduce the risk of sudden release of stored energy, which can cause injury or damage.

Taking the time to release tension safely demonstrates a commitment to prioritizing safety throughout the adjustment process. Rushing or neglecting this step can have serious consequences, so it’s important to proceed with caution.

Follow Manufacturer Instructions

Every garage door system is unique, and manufacturers provide specific instructions and safety precautions for adjusting the springs. Before beginning any adjustments, it’s advisable to refer to the manufacturer’s manual for your garage door opener. These instructions typically include guidelines for proper spring adjustment, as well as recommendations for maintenance and safety procedures.

Following manufacturer instructions ensures that you’re adhering to industry best practices and guidelines. It also helps you avoid common mistakes or oversights that could compromise the safety or functionality of your garage door system.

Make Small Adjustments

When adjusting garage door springs, it’s best to proceed with small, incremental adjustments. Making drastic changes to the tension of the springs can lead to instability or imbalance in the door operation. By making small adjustments and testing the door after each change, you can gauge the effectiveness of your adjustments and ensure smooth and reliable operation.

Small adjustments allow you to fine-tune the tension of the springs gradually, optimizing the performance of your garage door system. It’s essential to exercise patience and diligence throughout the adjustment process to achieve the desired results safely.

Call a Professional if Unsure

While some homeowners may feel confident in their ability to adjust garage door springs, others may prefer to enlist the help of a professional technician. If you’re uncertain about any aspect of adjusting the springs or if you encounter unexpected challenges, it’s best to call a qualified garage door technician for assistance.

Professional technicians have the knowledge, experience, and specialized tools required to handle garage door spring adjustments safely and effectively. By seeking professional assistance for commercial door services, you can avoid potential risks and ensure the long-term reliability and safety of your garage door system.

Don’ts for Adjusting Garage Door Springs

Adjusting garage door springs is a task that demands caution and precision due to the inherent risks involved. Mishandling or neglecting safety protocols during this process can result in severe injuries or damage to property. To ensure a safe and effective adjustment process, it’s crucial to be aware of the common pitfalls and mistakes to avoid. Here are some key “don’ts” for adjusting garage door springs:

Do Not Attempt Adjustment Without Knowledge

One of the most significant mistakes you can make when it comes to garage door spring adjustment is attempting it without adequate knowledge or understanding of the mechanisms involved. Garage door springs are under high tension and can pose serious risks if mishandled. Without proper knowledge of how these springs operate and the correct adjustment procedures, you’re putting yourself and others at risk of injury or accidents.

Before attempting any adjustments to your garage door springs, take the time to educate yourself about the specific type of springs your door uses and the recommended adjustment techniques. Refer to the manufacturer’s manual for guidance, or consider consulting with a professional garage door technician if you’re unsure about how to proceed safely.

Don’t Attempt to Repair Broken Springs Yourself

If you discover that one or more of your garage door springs are broken, it’s imperative not to attempt to repair them yourself. Broken garage door springs can release a significant amount of tension suddenly, posing a severe risk of injury or property damage. In addition to the danger posed by the broken spring itself, attempting to repair it without the proper knowledge or tools can exacerbate the situation and lead to further damage.

Instead of attempting a DIY repair, contact a professional garage door technician to assess the situation and perform the necessary repairs safely. A trained technician will have the expertise and equipment needed to replace the broken spring and restore your garage door to proper working condition without putting anyone at risk.

Avoid Overtightening Springs

When adjusting garage door springs, it’s essential to achieve the right balance of tension to ensure smooth and reliable operation of the door. However, overtightening the springs can lead to a host of problems, including premature wear and tear, damage to other components of the garage door system, and increased risk of accidents or injuries.

Resist the temptation to tighten the springs excessively in an attempt to compensate for other issues with the door, such as sagging or difficulty opening and closing. Instead, focus on making gradual adjustments within the recommended range specified by the manufacturer. If you’re unsure about how much tension to apply or if you encounter resistance during the adjustment process, stop and seek professional assistance to avoid causing further damage or compromising safety.

Do Not Remove Safety Cables

If your garage door is equipped with extension springs, it’s essential to ensure that the safety cables are properly installed and maintained. These cables are designed to prevent the springs from causing damage or injury in the event of a sudden failure or breakage. Removing or tampering with the safety cables can compromise their effectiveness and increase the risk of accidents or injuries.

Avoid the temptation to remove or disable the safety cables as a quick fix for issues with the garage door springs. Instead, inspect the cables regularly for signs of wear or damage and replace them as needed to ensure continued protection and safety.

Avoid Using Improper Tools

Using the wrong tools or attempting to improvise with makeshift solutions when adjusting garage door springs can lead to accidents or damage to the door system. Garage door springs are under high tension and require specific tools and equipment for safe and effective adjustment. Attempting to use tools that are not designed for this purpose or that are not properly sized or calibrated can increase the risk of injury or cause damage to the springs or other components of the door system.

Before beginning any adjustment work on your garage door springs, ensure that you have the proper tools and equipment on hand. This may include winding bars, vice grips, safety glasses, gloves, and a sturdy ladder. If you’re unsure about which tools are needed or how to use them safely, consider consulting with a professional garage door technician for guidance.

Don’t Ignore Signs of Spring Wear or Damage

Garage door springs are subjected to constant tension and movement, which can lead to wear and tear over time. Ignoring signs of spring wear or damage, such as rust, corrosion, fraying, or deformation, can compromise the safety and performance of your garage door system. It’s essential to inspect the springs regularly and address any issues promptly to prevent accidents, injuries, or costly repairs down the line.

If you notice any signs of wear or damage to your garage door springs during routine maintenance or inspection, don’t ignore them. Contact a professional garage door technician to assess the situation and recommend the appropriate course of action. Whether it’s replacing worn-out springs, lubricating moving parts, or performing other maintenance tasks, addressing issues proactively can help ensure the continued safety and reliability of your garage door system.


Adjusting commercial garage door springs requires careful attention to safety protocols and proper techniques to ensure optimal performance and longevity of the door system. By adhering to the dos and don’ts outlined in this guide, businesses can minimize the risk of accidents, equipment damage, and costly repairs associated with improper adjustments. Prioritizing regular maintenance and professional servicing will further contribute to the safe and efficient operation of commercial garage doors, promoting a productive and secure workplace environment.
