The third-car garage door on my recently-built house seems to have a bracket loose. The bracket in question is one that seems to go around the torsion spring and screws to the door frame header - it looks as though the builders just missed the bracket's position when they added 2x4s to attach the bracket.
Picture for reference:
My question is whether or not this is something I can address myself. It is as straightforward as putting another 2x4 in there and screwing the bracket to it? Does the bracket have some influence on the torsion spring, such that I need to have it professionally taken care of? I know that garage door springs are dangerous if not treated with care, and I don't want to get into something I'm not qualified to tackle.
