The lower part of one of my garage doors often gets wet due to splashes from water dripping on puddles outside, and the lower part of the door where one of the metal brackets with a roller attaches is rotted. I've started to look into it, and there aren't good options to only replace that one panel, and I'd like to avoid the cost of replacing the entire door.

What I'm looking for, if it exists, is a way to mount a larger metal plate or bracket to a larger part of the door close to the middle that isn't rotten. I'm not sure if such a standard plate exists, vs. finding an option a sheet metal plate or U bracket that I could mount and attach the existing hardware. We need to consider that even if I can mount the metal plate to a non-rotted part of the door, we need some way for the bolts to be stably mounted. If there isn't some kind of larger replacement bracket with everything built in available, perhaps there's a metal bracket with threads that would accept bolts, or, failing that, we could use a bolt that goes through the door/U bracket and into a nut on the other side. Links to any products would be appreciated.

Find a way to replace the whole bottom panel. Make one from scratch if you have to, it's just a piece of wood.

Anything else you do to repair it will require the same skills and the same effort to repair the rotten area, plus a lot of extra effort and material to attach that solidly to the undamaged part of the panel. Metal brackets, loads of screws, and some way to hide all this from appearing on the outside. I don't see the point. Whatever you do to chop out the rot and replace it, just do that, across the whole width of the door.

There is great danger in this from the heavy door and powerful springs. Make sure you are aware of how to detach the cable from the bottom brackets while the springs are not tensioned, and the door is supported some other way. There are lots of youtube tutorials on this.

So, replace that section of wood, scarfing in a good bit - I would be using glue and large dowels.

Then look to improving the drainage so the puddles don't collect and recreate the problem.
