Foggy Window Repair

Why Windows Get Foggy

Modern windows use insulated glass units (IGUs)—two or three panes of glass with an air or gas fill between them, sealed around the edges. This sealed airspace provides insulation. When that seal breaks down, moisture from the air gets between the panes, and you see fog, condensation, or a hazy film.

Seals fail for several reasons: age and weathering, thermal cycling (expansion and contraction), poor original manufacturing, or damage to the frame that stresses the glass. Once the seal breaks, there's no way to repair it—the sealed unit needs replacement.

Signs Your Window Seal Has Failed

• Fog or condensation between the panes (not on the surface)
• Milky or hazy appearance that won't wipe clean
• Visible moisture droplets inside the glass
• Distorted view through the window
• Mineral deposits or staining between panes

The Repair Process

Assessment: We inspect your window to confirm seal failure and check the condition of the frame and sash. If the frame is sound, sealed unit replacement is the right solution.

Measurement: We measure the existing glass precisely—thickness, dimensions, and any special features like Low-E coatings or tints.

Fabrication: A new sealed unit is manufactured to match your existing glass specifications.

Installation: We remove the failed unit and install the new sealed glass, ensuring proper glazing and a weather-tight fit.

Why Replace Just the Glass?

Full window replacement costs significantly more than sealed unit replacement. If your frames are in good condition—no rot, warping, or damage—there's no reason to replace the entire window. You get clear glass, restored insulation, and the same appearance for a fraction of the cost.
