How to Fix Moisture & Condensation Between Double Pane Windows

When condensation between double pane windows forms, the seal on the glass is broken. In humid climates, wooden window frames are often the culprit. The wood gets too wet and starts to rot and eventually the glass seal breaks down. In these situations, sometimes fixing the condensation between window panes is a matter of replacing a single pane and restoring its seal.

Tips to Fix Condensation Between Double Pane Windows

If there’s condensation between the panes of glass, you’re likely losing money on energy costs. Here are some tips on how to remove moisture from between your window panes:

  • Try cleaning the fogged windows to remove any buildup that isn’t condensation on the glass.
  • Replace a single glass pane instead of the entire window unit for a more economical way to defog double pane windows.
  • Drill small holes into the outer glass pane and install an air vent, which will increase the amount of ventilation and reduce moisture build-up.
  • If cracked or broken glass is the culprit of your foggy window, this can be repaired to prevent more condensation from entering the space between the panes.
  • If a window is old or rotting, you should have a professional evaluate whether the whole window needs to be replaced.

At Glass Doctor®, we’ll help you save money by replacing a single pane instead of the whole window, given that the damage to the seal or glass isn’t too extensive.

How Insulated Glass Works

With double pane windows, the insulating airspace in between the glass panels maintains consistent temperature and reduces heat loss. Most modern windows have two seals: an inner seal to protect against moisture and corrosion, and an outer seal to protect the strength of the window. The seals hold a spacer in place—usually a tube containing water-absorbing chemicals, otherwise known as a desiccant.

Why Do Seals Break?

For the most part, insulated glass windows work extremely well. They can withstand handle all types of weather, including cold temperatures, heat, and humidity, as well as repetitive open and close motions. With the double seal, when one seal begins to break, the other can hold the line for a while. However, as the window ages its components begin to break down, and the standard lifespan of double pane windows ranges from 10 to 20 years.

Other than old age, there are two additional factors that affect seal breakage:

  • Water retention in the frame or improper drainage around the window.
  • Direct exposure to sunlight—the more sun your window gets, the more heat will build up causing the panes to expand, contract and eventually weaken.

Once the seal is broken, moisture begins to form between the panes, giving your windows a milky, foggy look. In addition to condensation, there are other reasons to get your windows fixed:
