5 Signs That Your Garage Door Springs Are About To Snap

An automatic garage door has springs that help open and close the door. Torsion springs stretch across the top of the door, while extension springs hook up to each side. Spring repair and replacement are best left to professionals, as high-tension springs can pose quite a hazard when they are being replaced.

1. Visible Corrosion

Although it's not recommended for homeowners to try to adjust or replace springs themselves due to safety concerns, a visual inspection is safe and should be part of your normal routine. Rust and corrosion are fairly apparent even from a distance. In cases with only mild corrosion, your garage door tech may only need to clean and lubricate the springs. Severe corrosion means it's time to replace the springs.

2. Stretched Coils

As the springs age, they begin to weaken. They may not coil back up as tightly as they used to, which can affect operation. Much like rust, stretched spring coils can often be spotted without actually getting too near or handling the springs. If you notice any gaps in the coils when the springs are not stretched, then it's time to replace them. Generally, extension springs should be coiled tightly when the door is open, and torsion springs should be coiled tightly when the door is closed. 

3. Bouncy Door

If you aren't sure about the state of the springs, a quick check for a bouncy door can help you safely determine their condition. Pull the manual release to temporarily disconnect the door from the automatic opener, then manually open the door about halfway before letting it go. If the door begins to bounce or close, even partially, then the springs are no longer working as they should. 

4. Loud Noises

Garage doors aren't necessarily quiet, but any new noises should be investigated until the cause is found. Creaking, squealing, or grinding noises from any of the springs may indicate impending failure, or these noises may simply mean the springs and door require some general maintenance and lubrication. Regardless, bring in a garage door service as soon as you notice odd noises so that repairs can be made.

5. Sagging Door

The weakening or complete failure of the torsion springs can cause a garage door to sag in the middle, which is most noticeable when the door is closed or only partially open. Sagging can also affect one or both sides if the extension springs are failing. Sometimes, sagging can be severe enough to prevent the full operation of the door. Replacing the damaged spring solves the issue.
