Condensation on your windows is more than a minor irritant. As it drips down and soaks into wooden areas, it can damage your windows, window frames and even the framing inside the wall. Here’s how you can avoid it.
As we’ve discussed before, you can warm the inside window surface through any number of methods, from insulated, low-e glass to plastic sheeting. This will also help you feel warmer in the winter.
But other techniques will help you cut down the moisture, and might be worth looking into.
You can go to the root cause and decrease the humidity in your home. (Even if your windows are dry you may have too much humidity.)
If you have a humidifier, check your humidistat settings to make sure the humidifier’s not pumping out too much moisture for the outdoor temperature.
Install exhaust vents with powerful fans (100-plus cubic foot per minute) in your bathrooms, laundry room and kitchen… and use them. These areas produce an incredible amount of moisture, and if they’re not vented properly, the moisture inevitably finds its way to your windows.
Or you could install a dehumidifier.
You can also try and increase air circulation in your home. Run ceiling fans, or run your furnace fan continuously to help evaporate the condensation before it can do damage.
A note for plant lovers: putting plants in your windows may be good for the little darlings, but they’re a source of condensation. So move them if you can.
If these techniques haven’t cleared your humidity problems, you may want to investigate a heat exchange system.
