There are three main things that happen to garage doors. Something might shift out of place, which means that a garage door spring repair is needed. This is fairly easy and quick to fix. Sometimes, small things break or stop working in garage doors. Usually, these can be easily fixed with a garage door spring repair. Lastly, if your garage door spring has ceased to function, a garage door spring replacement might be needed. This will happen if adjustments and repairs do nothing to the spring to make it function again.
