How to Tell if Your Double-Pane Windows Need to be Replaced

Published on

New double-pane windows offer a number of perks for homeowners in Falls Church, one being better energy efficiency. Whether you’re researching online or with an expert at a showroom, energy efficiency is a critical factor in the purchasing process for replacement windows. Double-pane windows are a great choice if you’re wanting increased efficiency.

Many new double-pane windows contain argon, a colorless, nontoxic gas that has a greater density than air, which provides additional insulation from heat and cold.. However, if you notice that your windows have become “foggy” or if they have developed condensation, you’ve likely developed a greater leak and the gas has been switched with moisture. There are a few things that you can do to determine if this is what’s occurred:

  1. Clean the exterior and interior portion of your glass to be sure that the condensation or fog you’re looking at is in between the glass, not on the glass.
  2. If you realize that the moisture is in fact between the glass, you can contact the manufacturer to determine if you can claim it under your warranty. 
Depending on the age of your windows and the conditions causing the leak, it may make sense to start searching for replacement windows. Insulation is one of the most important qualities of your windows, and if that is compromised it can change your heating and cooling costs.
