I have put new windows in and now I have so much moisture. What do i do?

put new windows in and so much moisture that it runs out between the wall and floor. I pulled the sheetrock and there was ice behind my insulation. I have mold in some places and boards softening. When it rains my windows do not leak. They just have moisture in the winter time and freeze up

It seems like your air is stagnet in your house get a barometer to check your humidity level first,if it reads to high you should install an air exchanger,this will help remove the humid air from your house and is alot healther for you and your family if you have a very small house you might get by with a portable dehumidifier,check your square footage with the model.You will be amazed with the amount of water that comes out of the air.
