I would like to know what good tension should look like for the springs and cables so I can do myself.

Interested in straightening a bent metal part of door not shown in picture

Angie's List is not about, DIY it's about not getting ripped off by a contractor.

I'm for fixing a bent garage door, too.

Good visual information, but the article quit way too early. I'd like more-specific information on maintenance to perform on the door, how to replace a single bent door panel without having to replace the entire door, etc.

would you recommend spraying foam insulation on the back of the door?

Lubricate with silicon which last longer than just WD 40 ect.
