How to Get Rid of Cold Weather Window Condensation

Window condensation is a common problem in many homes in cold climates.  Not only is it just plain a nuisance, but it can also can create a hazard to your family’s health if left unchecked.  Simply put, moisture causes mold to grow, and if let go long enough…it can soon take over a room. Not only that, but as moisture on windows accumulates and sets into the wood frames around your windows, the wood can begin to break down, weaken, and essentially disintegrate.  This of course can  be very expensive to repair. Fortunately, we’ve found a few handy tips to help alleviate window condensation.

The first thing to do is to make sure that adequate ventilation is available in your home. You can utilize ceiling fans to make sure that the air is circulated around the room. It is also advisable to install exhaust fans in the kitchen and in the bathroom. You may also want to ensure that there are no obstructions inside the air vents and that the windows are opened once in a while to prevent inadequate air circulation.  If you have a home with older “leaky” windows, this may actually be a good thing in preventing condensation. This is because the warm, moist air in your home can escape through the cracks.  This isn’t an ideal situation obviously because your home heating efforts are literally going out the window.

Does Reducing Help Eliminate Window Condensation?

An important thing to remember is that window condensation…and by extension all moisture on windows… forms when the relative humidity in the room is too high for the temperature. Thus, you can either reduce the humidity inside the room or increase the temperature of the window’s surface. You can minimize humidity inside the room by utilizing the air vent when you are washing clothes, using the dishwasher, or cooking. The air vents or exhaust fans will ensure that the moisture is sent to the outside. You may also want to water your indoor plants by bringing them out of the room. Live plants always produce moisture and this effect is at its peak after the plants have just been watered. Firewood can also release moisture into the air so try to avoid keeping too much of  it inside the house. It is also essential to check the insulation for the attic for any discoloration that could serve as a clue that there is too much moisture in the room.

How to Control Window Condensation

Meanwhile, when window condensation appears, it is advisable to wipe it off using a rag. This is vital if you want to minimize the possibility of having a mold problem. Make sure also that the rooms are heated because the warmer air is, the more humidity it would be able to contain and this is less humidity or water that will appear as condensation on the window.

Another important strategy is to get a dehumidifier. The size for your dehumidifier will depend on how large your room is. Before going out to shop for a dehumidifier, it is advisable to obtain the measurements of your home to ensure that you will be able to purchase a properly sized dehumidifier. If you currently have a whole house humidifier attached to your furnace, than you can also make sure to lower the settings on it, or shut it off completely.   This will cause the air flowing through your HVAC system to become much dryer which will in turn not produce moisture on the window surfaces and continue to keep the window condensation problems to a minimum.
