A garage door with a broken torsion spring can fall rapidly and cause injury or death. However, the most common danger comes when your torsion springs break and you decide to undertake the repair/replace them yourself. Torsion springs can be very dangerous, and you not only need the exact tools for the job, but also need to have a good knowledge of the mechanics involved. Some of the parts involved in such a process can be life threatening, and must be handled with care and precision, which is why it is always recommended that you call in a professional, rather than trying to handle a replacement or repair by yourself. Failure to do so may leave you with injuries and/or damage to your property.
