We have a Muskin home too, but no issues with condensation. May I ask what you set your thermostat at?

I don't know much about this because I have never gone through such kind of problems with my windows.

I agree that the humidifiers are a great help. People are usually confused when and how to use the humidifiers to get maximum benefits. I found great information online and then had decided to purchase one that best suited our needs. We got the XL one.
