We often get calls from customers wanting to know “Why is my windows fogging?” Many times people think the windows are to blame for the excess condensation. This is simply not true. The extra water at your windows is because of the high humidity in the home. The cool glass is where it lands and is visible. Here are a few things you should know about why there is condensation at your windows.
How Much Condensation Is Too Much?
If your windows fog up in the corner from time to time, that is usually not a problem. If on the other hand your entire window fogs up or you see pools of water in the windowsill, you have a problem that needs addressed. Homes today are built better and “tighter” than homes 20 years ago. We also have better appliances and more energy efficient heaters and appliances and more energy efficient windows that allow more moisture to remain in the home. Homes are built tighter with less cracks and outside air seeping in. This is good for your utility bill but causes the moisture to remain in your home.
Where Does the Moisture Come From?
Moisture in your home comes from a variety of places. Each person in your home generates some moisture. Moisture also comes from showers, appliances, laundry and dishwashing. A family of four can generate close to 20 gallons of water each month. This water vapor or humidity is invisible in the air.
When Is Condensation Normal?
You can expect condensation after new construction. New homes are open to the elements for some time and have excess moisture. Usually this condensation disappears after one winter season that the heater is used. There will be condensation at your windows when the temperature changes drastically at once. Also during the summer months, your home will accumulate moisture. This built up humidity will show up at the beginning of winter.
Is Window Condensation a Problem?
Besides causing water around your windows, you may find the wood around your windows is getting water damage. Water damage can also occur in the drywall and flooring. High humidity will move toward cool dry air. This movement exists and causes the water to pass through wood, plaster and cement; the basic building materials in your home. Cool dry air in the winter pulls the moisture into the building materials and walls in your home. Excessive condensation at the windows is a sign that excess moisture may be damaging areas of your home you aren’t aware of yet. It can go through siding and blister paint. It can also seep into the attic where it may cause water damage in your ceilings. If you notice excess moisture it’s important to take action. Many of the building materials in your home have moisture-blocking materials like varnishes, tile, paint and plastic coverings to protect your home. The problem is this causes your home to retain the moisture and humidity even more.
How Can I Get Rid of Moisture?
If you’re wondering “Why is my windows fogging?” it may be time to take action and keep the humidity down to a minimum. You can help by reducing the moisture and allowing it to escape your home. Here are a few steps you can take:
- Open the windows in your home a few minutes each day, especially after running the dishwasher, taking a long shower or doing laundry.
- Run ventilation fans in the kitchen and bathroom longer.
- Keep your fireplace damper open
- Run your heater
- Remove or turn off humidifiers
- Vent gas burners and clothes dryers
When humidity is a severe problem in your home you can call an electrician or your heating and air company to install ventilation fans, vents for your gas burners, heaters and appliances.
