Signs You Need a Window Seal Repair

Most homeowners don’t notice when the seal breaks around their windows. However, if left unrepaired, you can experience significant negative effects. If you experience the following, you should have your window seals repaired or replaced.

  • Foggy windows that don’t wipe away. The moisture is within the two or three panes of glass.
  • Higher energy bills in the summer and winter because the argon gas between the two windows that provided insulation has leaked out due to the failed seal.
  • Mold and mildew around the window sill are caused by excess moisture.
  • Water damage around the window as moisture seeps in through the gaps in the seal.

FAQs About Window Seal Repair

What is a window seal?

In double or triple-paned windows, often called thermal or insulated windows, there is a gas insulation, such as argon, filling the void between the panes of glass. Then, a perimeter seal is installed around the windows to lock the gas in and stop outside air and moisture from entering the home.

If the window seal fails or breaks the inert, harmless gas within the window will escape, allowing hot or cold air and moisture to enter.


Fixing a window seal is not a difficult task, but it does require specific tools and expert knowledge. Our Cary window repair specialists will first test your window for leaks by conducting a test to determine where the energy is escaping to. Then, we will remove old caulk, seal gaps, add add brand new weatherstripping and caulk to repair your window seal.

Cary homeowners can extend their window seal’s life by avoiding spraying window seals with a pressure washer. However some natural events, such as high winds and shifting of the ground under the house can cause unavoidable damage to your window seals.
