How to repair deterioration on inside of window frame?
I would like to repair the damage visible in the picture, the damage extends along the entire bottom of the window. I would like to just tear into it but I'm not sure what is beneath the surface. I think there is aluminum or something like that under the paint. Is anyone familiar with this type of window installation and knows how to go about fixing it?
It looks like the area is getting damp and that is the main reason it looks that way. You will probably have to figure out where/why water is getting to that point. Yu might need a new window, or just some caulking or flashing on the outside to start, but more then likely, there is more damage that isnt visible until you tear it apart.
This is a two step process. You need to find out where the water is getting in and repairing the damage that's been done.
It looks like a flanged aluminum window. There are nailing flanges on the exterior, that are buried under the exterior finish. There should be drainage holes or channels under the screen so water can run out. Many times these are caulked and/or painted over so the water get into the framing underneath. Look at the other windows that don't exhibit this damage to see how they are set up.
The metal underneath is the steel corner bead used to finish an outside corner.
