The wooden frame either side of my up and over canopy garage door has rotted and I want to replace it. To do so I will have to remove and then replace the door. I thought this would be a fairly simple job but the door uses a single torsion spring to provide lift, and several web-sites I have visited suggest that releasing the tension is a job for experts and that people have been killed attempting this job DIY. Agree or disagree? Any general advice on actually releasing the tension?
