Rotten wood replacement in a window frame - help!
Hi there, and thanks in advance for any help you can offer with this!
I've had some storm windows built to replace some really old ones that were starting to rot. On first examination, it looked like the sash were rotten but the frame itself was in good shape. And it mostly is. But in preparing the frame today I noticed that about a 3-4" chunk of one corner is rotten. I managed to stick a screwdriver in there and wiggle it around a bit....
The question is - what next? How do I go about replacing the rotten part and ensuring that doesn't happen again?
This is an older 100+ year old house, with stucco around the wood frame for the windows.
Any help and advice is greatly appreciated!
