Even the most highly skilled DIY enthusiasts can struggle with garage doors especially when a Torsion spring needs replacing. This is installed directly above the door opening and it distributes the garage door’s weight evenly and it could certainly cause an injury if it’s installed incorrectly.
You should only aim to replace a torsion spring if you have the right tools and experience, while you should always follow the instruction that come with your new spring extremely carefully. This spring is mainly used on heavy doors and you should really get you head around the instruction before you carry out the installation.
If you’re not entirely confident on your skills or your tools then you should always hire a professional, otherwise you could injure yourself or cause damage to the garage door, meaning you have to pay out for more replacement parts.
