15 year old house with good quality wood windows has a paint peeling problem on the exterior side, interior no problem
house has had a condensation problem recently rectified by venting the rangehood fan to the outside
my question is would excessive interior moisture affect the exterior paint on a window and what to do about it
the quality of the installation ie vapour barrier/insulation has not been determined yet, but the house is relatively well built
the house is in southwestern ontario

Greetings steve,
This post, in response to your question, will bump the thread through the 'recent discussion' listing again.
Perhaps it will catch someones attention that can help you with advice.

Interior condensation is not likely to cause paint peeling on the exterior, in my experience.
The paint could be peeling because the painter applied an oil based paint on a humid day/time of the year. You haven't said whether the exterior is brick,block, vinyl, wood or other which would help to diagnose the problem. It's also possible the painter didn't do the prep work for a good job; finish coat with no primer or perhaps the house was a rental and has the cheapest paint possible. Or a leak formed between the paint and the exterior.
Also, is it peeling all around the house? or maybe just under constant southern exposure?
If the exterior paint is 15 years old and peeling then it's time to paint the windows again. Actually 15 yrs for a paint job on the exterior is quite good. Paint the windows again with proper preperation with an oil based paint and you should get at least 5+ years. Wood windows will always maintenance in the form of painting. It's the only thing protecting the wood so don't let it go too long if it's peeling.

actually the window was repainted two years ago by others, it has an easterly exposure so excessive sun is not an issue
i scraped it down to bare wood, sanded, primed and repainted last weekend
all of the other windows are in really great shape though
thanks for the info
Yep, 15 years is better than average for the initial paint job on wood windows. They come from the factory with a "factory primer" that is really just a paint applied to protect them until the final coat -- it's a lousy primer, and paint bonds to it very poorly (especially if not sanded before painting).
But after the first scrape/sand/prime/repaint cycle you usually get better adhesion.
