Window Seal Failure: Why Your Windows Look Foggy and What to Do About It in Flat Rock, MI

If your windows look cloudy, foggy, or have moisture trapped between the glass, you may be dealing with window seal failure. This is a common problem for homeowners in Flat Rock and throughout Downriver, especially with Michigan’s changing seasons.

In this post, we’ll explain what window seal failure is, why it happens, how to spot it, and what you can do to fix it.

What Is Window Seal Failure?

Most modern windows use double-pane or triple-pane glass. Between the panes is an airtight seal filled with insulating gas, usually argon. This seal keeps outside air and moisture out while helping your home stay comfortable.

Window seal failure happens when that seal breaks.

Once the seal is broken:

• Moisture gets trapped between the panes

• The glass becomes foggy or hazy

• The window loses energy efficiency

Unfortunately, once the seal fails, it cannot be repaired.

Signs Your Window Seal Has Failed

Window seal failure is not always obvious at first. Here are the most common signs:

• Fog or cloudiness between the glass panes

• Water droplets trapped inside the window

• Windows that feel cold in winter or hot in summer

• Rising energy bills

• Drafts near the window frame

If you see fog that does not wipe off from either side, that’s a strong sign of seal failure.

Why Window Seal Failure Is Common in Southeast Michigan

Homes in Flat Rock, Downriver, and Southeast Michigan are exposed to extreme temperature changes throughout the year.

Common causes include:

• Freezing winters and hot summers

• Constant expansion and contraction of the glass

• Poor original installation

• Low-quality window materials

• Older windows nearing the end of their lifespan

Over time, these factors put stress on the window seal until it breaks.

Why Seal Failure Is a Big Problem

A failed window seal affects more than just appearance.

1. Higher Energy Bills

Once the insulating gas escapes, your window no longer blocks heat and cold effectively.

2. Reduced Comfort

Rooms may feel drafty or uneven in temperature.

3. Moisture Problems

Trapped moisture can lead to mold growth and damage surrounding materials.

4. Lower Home Value

Foggy windows make a home look neglected and outdated.

Can a Failed Window Seal Be Fixed?

In most cases, no.

Once the insulated glass seal is broken, the best solution is:

• Glass replacement if the frame is in good shape

• Full window replacement if the window is older or damaged

Trying to “defog” a window is usually a temporary fix and does not restore energy efficiency.

How Proper Installation Prevents Seal Failure

One of the biggest causes of early seal failure is poor installation.

A proper window installation includes:

• Correct sizing

• Level and square placement

• Proper insulation around the frame

• Correct fastening to prevent stress on the glass

Even the best window can fail early if it’s not installed correctly.

When Should You Replace a Window with Seal Failure?

You should consider replacement if:

• The window is over 15–20 years old

• Multiple windows show fogging

• You feel drafts or temperature changes

• Your energy bills keep rising

New replacement windows are far more efficient and reliable than older models.
