When you upgrade your windows and doors with high efficiency, impact products you may experience condensation issues.   This has nothing to do with improper installation, but just the opposite is true.  Now that your home is properly sealed the temperature differential between the interior and exterior of the home coupled with high humidity can cause condensation.  

Let’s take a look at some common causes and some recommended solutions to reduce condensation. 

Exterior Condensation

Exterior condensation, also known as dew, is the result of the window or door being cooled from the indoor temperature as compared to the temperature outside, which is a common scenario in South Florida.  Exterior condensation on a properly sealed home is perfectly normal.   An air conditioning vent blowing directly on an exterior window can also cause exterior condensation.   

Potential Solutions

  • Sunshine and the daily heat of the day typically takes care of exterior condensation. 
  • Position air conditioning vents from directly blowing on windows.
  • If it really bothers you take the time to wipe down the outside of your windows or doors. 

Interior Condensation

This is a result of high indoor humidity that can be caused by the following reasons:

  • Air conditioner is not working properly and removing indoor humidity.
  • Poor ventilation.
  • Showering & Bathing.
  • Cooking.
  • Laundry.

Potential Solutions

  • Reduce Moisture
    • Have your HVAC system checked to make sure it is properly dehumidifying your home.
    • Purchase a dehumidifier or employ a moister eliminator, such as Damp/Rid. 
  • Circulate the Air
    • Install bathroom and kitchen exhaust fans and utilize them during and for 15 minutes after cooking, bathing and doing laundry.
  • Improve Ventilation
    • Open window and door coverings during the day.
    • Install ducting that will take air to the outside of your home when washing or drying clothes.
  • Raise the temperature in your home. 

Condensation between the Glass Panes

Condensation buildup between glass panes is abnormal and is indicative of a faulty window or door seal.   First try to wipe the interior and exterior panes to determine if the condensation is indeed between the glass panes.  If there is still moisture then you will want to contact the manufacturer or dealer to determine how to handle the faulty window or door.
