Repairing rotten windows

[kevviek]

Seems everything I look at in this holiday house has rotted. This window frame is cedar but the front part was completely crumbly so I cut it off and was planning to simply screw another piece on front, after putting some wood hardener in the gaps and filling with bog.

Open to other suggestions, I have just replaced the weatherboards and don’t want to pull the windows out and I don’t think it’s feasible to replace the whole bottom piece?

The last photo is of one of the windows that doesn’t have much rot, for context.

Sorry to say but it looks like it has gone too far and complete replacement of the bottom sill is the only option in my opinion.

Do you think it’s feasible to do that without removing the full window, eg just taking out the two bottom glass panels?

Without first hand examination it’s impossible to say, but may be possible depending on construction.

Probably.

I have had to make this exact same repair, on multiple windows on a previous house. I also had to replace the bottom 30cm of the sides on a couple of the windows, and this was on the top story of that house. At least you are nearly at ground level.

I don't have any photos though. This was pre-digital photography.

Window needs to come out so the frame can be rebuilt. There's no way you can replace the sill properly without removing the whole window frame. It'd be easier just to get new windows fitted. All this should have done before doing the weatherboards.

I agree with the above. At least one of the images looks like dry rot also. Trying a bodge repair on this is throwing money away, no amount of bog or chiselling will remedy this. Replace them.

Fully agree with the 2 previous posts. I'd be very hesitant to try a botch job which could end up later on being more costly than replacing the whole window.
