What causes condensation on windows?

There are several factors that create condensation on windows.

Normal breathing and perspiration add three pints of water to the air every day for each person in your home. In fact, every activity that uses water adds more moisture to the air, including cooking, taking showers, dish washing, and doing laundry.

If you have too much moisture in your home, be mindful of:

  • Dripping faucets.
  • Any containers in the home that have water standing often or all the time, such as sinks, pet bowls, and open fish tanks.
  • Drying clothes indoors, or leaky clothes dryers.
  • Gas cooking; moisture is a by-product of gas combustion.
  • Open toilet lids.
  • Exhaust fans that aren’t used during baths and showers to remove the moisture.
  • Excessive use of things like steamers, plant misters, or teapots.
  • Some building slabs may not have a vapor barrier.
  • Overuse of humidifiers.
  • Faulty plumbing, such as leaks in walls or under cabinets.
  • Leaking hot water heaters or water piping.
  • Outdoor drainage that holds water against slab or bricks. You may need to inspect your sprinkler system, too!
  • Faulty shower piping, or faucets and seals leaking into walls.
  • Leaky refrigerators or ice machines that drip or drain excess water or moisture.
  • Poor ventilation in bathrooms.
  • Air conditioning.
  • Doors that are too tight, impeding circulation of air from the room.
  • Extensive soaking of clothing in open water containers. You may wish to move these to the garage or utility areas.
  • Wet clothing, washrags, or towels repeatedly left lying out.
  • Rainwater leaking into the attic and/or walls.
  • Use of open space gas heaters, especially at high room temperatures.
  • Poor refrigeration or faulty condition of the cooling system that doesn’t remove enough moisture from the air. Have this checked by a technician.
  • Floors left wet after mopping.
