I was working on my garage door the other day and I noticed that the steel supporting strut (or more appropriate name for this? See the picture) tilted due to a loosening bolt, the ceiling cracked because of that too.
It concerns me. It's obviously the strut is no longer secured but I don't know how long it can hold. I can't tell what material inside the ceiling that the bolts stuck into either.
My question, if I want to fix this, how should I start? Or, honestly I don't think I am up to a job like this, so another question: if I want someone to come over to fix this, which category of professions this kind of work falls into? So that I can start googling and shopping for professionals.
