Moisture Is Collecting Inside My Windows In Winter: Should I Be Concerned?

Condensation is a common problem on the inside of windows in winter time. As a homeowner, you may find it troubling to see an unexplained build-up of water inside your home--even if it only takes the form of a thin layer of moisture. However, condensation on windows does not necessarily point to a larger problem. Understanding the causes of condensation inside the windows as well as the signs of trouble can help you prevent any problems, and may prevent needless worry. 

Moisture Sources

Many newer homes are built to have a tight envelope, meaning that they don't let moisture in or out very easily. This is basically a good thing, because the more impenetrable the home's envelope, the more energy efficient that home is. Condensation forms inside the windows when humidity in the air inside touches the surface of the cold window, much in the same way that condensation forms on the outside of a cold glass of water in the summer. 

If you have an older home, condensation may still form inside the windows if the windows themselves are new and energy efficient. Even if your windows aren't new and your house is old, there are other reasons humidity can form inside your home.

  • Live plants. If your home has a lot of plants inside of it, the constant presence of moisture in the soil may be contributing to the buildup of moisture in the air.  
  • Fish tanks. One fish tank generally won't have an effect, but several fish tanks may. Evaporation from the fish tanks may add a lot of humidity to your home.
  • Photography hobby. Because of the tubs of water used to develop photographs, presence of a dark room in your house may contribute to a rise in humidity in your home.

Warning Signs

In some cases, condensation is a sign of a larger problem in the home. The problem could be a variety of issues, from a leak in the walls to a slab leak beneath the house. Watch for these signs of a moisture problem: 

  • Spots of mold growing on the walls.
  • Peeling paint.
  • Warped floorboards. 
  • Water spots on the walls.

If your home displays any of these signs of distress, call a contractor for an evaluation.

Solutions 

If you believe your home has acceptable levels of moisture but would like to eliminate the condensation problem, there are several possible solutions, including:

  • Ventilation.
  • Leave a window cracked in your home to let out excess moisture.
  • Open a door to the outside for 15 minutes every night.
  • Use a dehumidifier.

Each of these solutions has advantages and disadvantages, and each homeowner can choose the option that's right for him or her. For more information, contact Overcash Siding LLC or a similar company.
