Any fix for rot in wood frames besides replacement?
I noticed today that several of my exterior window sills have some rot. The paint layer is intact, so not til I pressed on one did I realize it.
The windows themselves (all wood) are perfectly fine. It's just the outermost portion of the sill. There are two parts to it: a section of wood ~ 4" deep right outside the window, which looks like it is part of the pre-hung window, and a strip of 2 x 2 (approx) that looks like it was applied with the outside molding after the window was put in it's opening. It is that 2 x 2 that seems to have the rot, plus a small part of the side molding where it meets that. Of course I can't see if the rot extends into the sill itself.
I could take a photo but with the paint still there, there is not much to see. Of course, it is mid October. I don't think I could get this fixed before it gets really cold, or find someone to do it. I am handy but no carpenter. I am afraid to totally leave it for the winter. If it extends into the sill I don't know what to do. It seems like overkill to replace a perfectly functioning window just because there is rot in the sill. Plus there is a marble tile backsplash on the other side that would be ruined if we did try to replace the whole window.
I remember hearing somewhere that there is a wood rot treatment that saves you having to replace the wood. I also heard somewhere about using Bondo. I know nothing about Bondo other than I used it on my first car decades ago :) A couple of friends of mine just did theirs with tuckpointing mortar. I guess they had it around and thought, why not.
Thanks for your advice.
