My house every winter has been gathering condensation a lot on the windows during winter. We've tried changing the temperatures in the house, and there's still condensation. Any help guys?

Have you tried running a dehumidifier at all? Try it in the rooms that are the wettest and see if that makes a difference. Also I noticed that my windows are not full of condensation when the weather outside has lower humidity. Also, do you have storm windows or double pained windows? That could play a big part also.

You should investigate any outside air leaking into your home via small cracks around the windows that need recaulked, around the doors, around the foundation. Condensation happens when outside humid air reaches the inside of a home via air holes (no matter how small). Also, look under the sinks in the bathroom and kitchen and seal up the holes where the water lines come into the house portion in the cabinets. This is another air leak even if it is into the basement.

I'm wrestling with that problem myself. It's primarily air leaks around the window frames. One room has remarkably improved and there are no drafts.

A bathrroom, was caulked and continues to have condensation. This has been traced to a bad weatherstrip at the bottom of the window. It has yet to be repaired. Another source of air intake that needs to be eliminated is that there is no check valve on the shower exhaust and the toilet supply penetration. You can feel the air easily on a windy day.

The windows are double-pane.

Condensdation means outside air leaking in,more caulk and maybe shrinkable plastic storm windows. Use an exhaust fan in the bathroom when showering and a hood fan when cooking. When remodeling I remove the trim on all exterior doors and windows and insulate with expanding foan made for window installations, don't use plain expanding foam.

I've also heard the reasoning is there making houses so tight these days and they don't breath properly. Sometimes I've heard you can run your furnace fan 24\7 and that will cut down on the condensation on the windows, or a lot of peope are getting air exchangers installed in there houses. A lot of newer homes an air exchanger is a given when they build them.

I agree about the furnace but for more than just this reason. I turn my fan from auto to ON the day I move into a home and it stays that way until I sell. The house is much more evenly heated and cooled, the starter windings in the fan never burn out and the extra electricity running 24/7 is minor compared to the juice it takes to start a fan every half hour.
