Just discovered rain leaking through this window into the garage below. The attached picture shows the extent of the rot in the bottom rail.I have chiseled and drilled into it to remove the rotted wood.I was thinking about sealing it and then applying epoxy filler to replace it.But is this too much damage for such a repair and also what do I do about the bottom seal? This is an Andersen window;about 20 years old. Was hoping this approach might work rather than having a carpenter replace the rail.
Every older Anderson or Pella wood or clad window I've ever seen rots out.
Remove and replace with a replacement window and never have to deal with it again.
I use Windcor or Simonton replacements and never had a recall.
