With an average of seven years, extension springs have a shorter lifespan than torsion springs. Similar to torsion springs, the quality of the metal used and the weight of the garage door influence how long they'll last.

The constant pulling force they endure with each opening and closing cycle weakens the metal faster. Homeowners should be extra vigilant for signs of wear, such as a sagging door or a slow-moving opener.

Never attempt to replace garage door springs yourself — consult a Precision Garage Door Service™ professional for inspection and potential replacement.

Most springs are made from high carbon steel wire, but there are variations in quality. Standard springs use basic high carbon steel, which works well but may not last as long. Oil-tempered springs undergo a special heat treatment process that makes them more durable.

Another important factor is wire thickness. Springs with thicker wire can withstand more cycles before succumbing to metal fatigue. This is because the thicker wire distributes stress more evenly. However, thicker wires also add weight to the spring, requiring a stronger motor to operate the garage door. So, it's important to choose springs with the right balance of wire thickness for the specific door weight.

Extreme temperatures and moisture can be detrimental to garage door springs. For example:

• High temperatures may weaken the metal in the spring, making it more prone to breakage.
• Cold temperatures can make the metal more brittle, making the springs more susceptible to cracks and sudden failure.
• Moisture exposure will eventually cause corrosion, which weakens the metal, reducing the spring's lifespan.
• High humidity or frequent rain or snow might cause springs to deteriorate faster.

The more cycles the springs endure, the faster they wear out. This is because each cycle puts stress on the metal, causing tiny tears and weakening it over time. Heavier garage doors naturally put more strain on the springs to lift and lower them.

Beyond these, any situation that puts excessive pressure on the springs can accelerate wear and tear. For example, a malfunctioning garage door opener that shakes the garage door or a storm with strong winds can damage the springs. Proper maintenance, such as lubrication and keeping the door balanced, can help minimize wear and tear and extend the lifespan of the garage door springs.

A noisy garage door during operation can be a warning sign that the springs are nearing the end of their lifespan. Be attentive to these sounds, as they can indicate a potential safety hazard and should raise concern:

• Loud popping: This is a classic sign of a broken torsion spring and requires immediate attention by a professional.
• Scraping or grinding: Indicative of worn rollers or a misaligned track, these sounds may also signify a failing extension spring that's no longer properly supporting the door's weight.
• Squeaking or screeching: High-pitched noises in your garage door spring are often caused by a lack of lubrication. Persistent squeaking could also point to failing springs that are putting extra pressure on other components.

Feeling increased resistance when manually opening or closing your garage door is a strong indicator that the springs might be worn out. Garage door springs counteract the weight of the door, assisting in lifting and lowering it. When the springs are new and functioning properly, they provide the necessary tension to balance the door's weight. This makes it relatively easy to move the door manually.

As springs age and weaken due to metal fatigue, they lose their ability to counter the door's weight effectively. This translates to increased effort required to lift or lower the door. If it’s a struggle to manage the door manually, it's a clear sign the springs aren't providing sufficient support and likely need replacement.

Uneven distribution manifests as a noticeable tilt or wobble in the door. For instance, one side of the door might be lagging or rising faster than the other. In severe cases, the door may even scrape against the opening or struggle to stay level at all.

These uneven door movements are a sign that the springs are failing to properly support different sections of the door, putting additional strain on the entire system and posing a safety hazard.

Visible damage to garage door springs is a clear signal that they're worn out and require immediate attention. Unlike some of the subtler signs, these visual cues provide a definitive reason for concern:

• Cracks: Over time, metal fatigue can cause cracks to develop on the surface of the spring. These cracks can worsen and eventually lead to a complete break, potentially causing the door to come crashing down.
• Rust or corrosion: Exposure to moisture will eventually lead to rust and corrosion on the springs. This weakens the metal and significantly reduces its lifespan. Look for signs of rust discoloration or flaking on the spring's surface.
• Physical gaps: In torsion springs, a visible gap between coils points to a broken spring. This gap won't be present in a healthy spring, as the coils are tightly wound together.
• Discoloration: While not as concerning as cracks or rust, significant discoloration on the springs might also be a sign of aging and potential weakening. This is especially true if the springs were originally bright and shiny and now appear dull or gray.

A sagging garage door is a telltale sign that garage springs are nearing the end of their lifespan and can no longer adequately support the door's weight. When this weakening occurs, the springs lose their ability to evenly distribute the weight of the door, manifesting as a visible sagging in the middle or along one side of the door.

Garage door springs function like counterbalances, assisting the opener in lifting and lowering the door smoothly. When they're new and elastic, they absorb the opener's momentum during the closing cycle, ensuring an even and gentle descent. However, worn-out springs lose this ability due to metal fatigue.

This lack of control translates to the door slamming shut with unexpected force. This slamming motion is not only a nuisance but can also damage the door and the opener motor and potentially cause injury. Stop using a garage door that slams unexpectedly immediately and contact service professionals for an inspection.
