🪟 Why Glass Gets Foggy — And How We Fix It

Written By hensen Medina

Foggy or cloudy windows might seem like a small issue, but they often signal a much bigger problem with your glass. At Supreme Glass & Windows, we get this question all the time: “Why is my window fogging up, and how do I fix it?”

Here’s everything you need to know about foggy glass — what causes it, how to prevent it, and how our team can restore clarity to your home or business.

💨 What Causes Foggy Glass?

Most foggy glass is the result of moisture trapped between the panes of a double-pane or insulated glass unit (IGU). This happens when the seal around the glass fails, allowing air and humidity to enter.

Once moisture seeps in:

  • It condenses between the panes

  • Creates a foggy or cloudy appearance

  • May worsen over time and affect insulation

🧊 Common Reasons for Foggy Windows

  • ✅ Broken or deteriorated seals

  • ✅ Extreme temperature changes

  • ✅ Poor installation or aging frames

  • ✅ High indoor humidity levels

🔧 How We Fix Foggy Glass

At Supreme Glass & Windows, we offer multiple solutions based on the severity of the issue:

🔹 Glass Replacement Only

We replace the fogged glass panel (not the entire window), restoring visibility and efficiency.

🔹 Full IGU Replacement

For more severe or repeated seal failures, we install a new insulated glass unit to permanently solve the problem.

🔹 Frame & Seal Repair

We inspect and repair window frames or seals to prevent fogging from coming back.

🛡️ How to Prevent Foggy Windows

Prevention starts with maintenance and awareness. Here’s what you can do:

  • 🌬️ Reduce indoor humidity with a dehumidifier or proper ventilation

  • 🧼 Clean and inspect windows regularly for signs of wear or leaks

  • 🧰 Schedule routine inspections to catch small problems before they become big ones

  • 🚫 Avoid using DIY sealants, which often make the problem worse
