Heavy Duty Garage Door Extension Springs for Garage Door

Garage door Standard extension springs are coiled accessories installed above the door's horizontal track. When the door is opened, the energy stored in the extended springs is used to lift the door. Garage door extension springs use resistance to help a door function. They’re tightly coiled and extend and retract as a garage door operates. In general, extension springs return a moving object to its original position. Something moves, which extends the spring, and the resistance in the spring pulls the object back. That’s how garage springs work.
In a garage door system, extension springs attach to pulleys and go above the door’s horizontal track. Tension in the spring then helps the door to operate.

Q1: How long do garage door springs typically last? 
A1: The lifespan of garage door springs can vary depending on factors such as usage frequency, maintenance, and environmental conditions. On average, torsion springs can last around 10,000 to 15,000 cycles, which translates to approximately 7 to 12 years of normal use. Extension springs, on the other hand, generally have a shorter lifespan of about 5 to 7 years. It’s important to note that regular maintenance and proper care can help extend the lifespan of garage door springs.

Q2: Can I replace garage door springs myself? 
A2: Replacing garage door springs can be a complex and potentially dangerous task. It involves handling high-tension springs and requires specialized knowledge and tools. It is highly recommended to hire a professional technician with experience in garage door spring replacement. They have the expertise and equipment necessary to safely remove and install new springs, ensuring that the door operates smoothly and safely.

Q3: How can I tell if my garage door spring is broken or worn out? 
A3: There are several signs that may indicate a broken or worn-out garage door spring. These include: The door is difficult to open or close: When a spring is damaged, the door may feel heavier than usual and become challenging to operate manually. Uneven or crooked door: A broken spring can cause the door to become unbalanced, resulting in it being higher on one side or appearing crooked when closed. Loud bang or noise: If you hear a loud bang or snap coming from the garage when opening or closing the door, it could indicate a broken spring. Visible damage: Inspect the springs visually for signs of wear, such as gaps or breaks in the coils or any signs of rust or corrosion. If you notice any of these signs, it’s advisable to contact a professional technician to assess and potentially replace the garage door springs. Attempting to operate the door with a broken spring can be dangerous and may cause further damage to the door or opener system.



It is very common for this system to fall victim to frequent use, and as the door is moving up and down, the steel in the springs will weaken and eventually break.
