Condensation Between Window Panes
Q: I have a house that was built in 1992, and has Andersen windows. During the winter and now even in November, some of the windows get moisture in the center of them. Not all the windows have the problem, though. It happens in the living room, kitchen and in the basement, which is finished.
I have been told that the house is too tight, so that there is not enough fresh air getting into it. I have checked the fresh air intake in the laundry room and that is OK.
We also have tried to leave a window open in the kitchen, but that does not help, and it gets moisture on that window when it is left open. I also was told it needs a cold air return system put on the furnace, but I wonder about spending that kind of money when the furnace does not run a whole lot due to our gas fireplace. Please let me know what to do?
A: If the condensation is occurring between the dual panes, then the seals have broken, which has nothing to do with the ventilation (exchange of fresh air) in your home. This is definitely the most common problems with dual pane windows; the units with broken seals will need to be replaced with new factory sealed ones. This is done by glass companies that repair all kinds of broken glass and mirrors.
You could check with the window manufacturer to see what kind of warranty they offer, but I am about 99% sure you will find they are out of warranty after this many years.
To locate a reputable professional to replace those units, please visit Home Advisor and enter a service request to be matched with the ideal service professional in your area.
