What to Do About Condensation

condensation on a window

Most condensation comes from humidity levels inside your home. Your old windows most likely had areas for this moisture to leak outside, so really what you're seeing is proof that your new windows/doors are doing their job to make your house more energy efficient.

There are two different types of condensation which both have different causes. Exterior condensation typically occurs when a cool night follows a warmer day – usually in the spring or fall. Exterior condensation is no cause for concern, in fact it's an indication that the window is performing as it should.

Interior condensation is caused by excess humidity in your home. Warmer air holds more moisture and when it comes into contact with a colder surface (the glass in your windows) it is cooled and moisture is released in the form of condensation.

Here are a few simple tips to help you deal with condensation inside your home:

  • Open your windows as much as possible to let the humidity escape outside
  • Use a dehumidifier to greatly reduce the humidity inside your home
  • Vent clothes dryers, gas burner, etc. outside
  • Use kitchen and bathroom exhaust fans

Many people think that the presence of condensation in new windows (when there was a lack of condensation with their old windows) means they are not doing their job. This is not the case. When you have new windows & doors installed you're basically tightening up any holes that were present with your old windows/doors. Now the humidity inside your home has lost its escape route to the outside world. When you see condensation on your new windows, what you're actually seeing is proof that your new windows/doors have eliminated air leakage points throughout your home.

Maintaining Your Investment

There are many things you can do to maintain your investment including cleaning your windows and doors annually or bi-annually as well as lubricating the operating components of your windows and doors. We recommend using a silicone spray on the all operating components including operating arms, handles, rubber seals, screws, hinges and lock cylinders. This will prevent from rusting, ice buildup or tearing of the rubber seals. On slider windows you should ensure all tracks be free of dirt and dust. At least once a year you should inspect the interior and exterior caulking and look for any cracks or missing sections.

Spraying the operating components provides a protective coating and allows for easier operation. Creating a good maintenance routine will ensure your products' longevity they deserve.
