Exterior Window Trims

[jc1985]

Hello. I hope this is okay to post. I had someone replace the window trims on an outbuilding however, it has started to rot. I’ve built fences and gates in the past and would say I’m relatively “handy”, but I was under the impression that the corners should be mitred in instances like this? I may be wrong. My question is if there is a particular kind of wood for this install I should be looking for? It will be painted but I will treat the wood prior to painting also. I have attached pictures. Thanks in advance.

The windows for log cabins need to allow growth and shrinkage of the logs through the seasons. they also need to be kept dry and painted properly. It looks to me as if the primer has lifted there on most of those bits, so cannot tell if it is untreated timber or badly prepared. Ours has similar windows but has no sign of failure yet after many years.

The existing frame just looks like it's butt jointed, no sign of any mitring, so the repair doesn't seem to different in that respect.

It looks like all you've got for your money there is that someone cut a piece of timber to approximately the right length and then screwed it on to the front, something that you could have done yourself if you're "handy"! I would have at least primed it before fixing it on.

It's interesting that the window frame seems to have rotted more than the timbers around and below it, eg IMG_4771.

It looks like the guy has screwed the timber to the log cabin rather than the lower part of the window "box".

And why did he totally ignore the rotten timber on the vertical section in the last image?

White uvpc might be better option , certainly won’t rot.
