Foggy Window and Glass Unit Replacement

Replace failed sealed glass units that fog between the panes, restoring a clear view without replacing the whole window.

When a double-pane window fogs up between the panes, the seal around the glass unit has failed. Moisture has gotten in, and it will not wipe away because it is trapped inside. The window can look cloudy, show water spots and lose some of its insulating value. The good news is that if the frame and sash are in good shape, the glass unit can often be replaced without replacing the whole window. Homeowners in Nashville call us about foggy windows after humid summers and cold snaps.

We look at the window to confirm that the fog is between the panes and not on a surface. We check the frame, sash and the age of the window, because a new glass unit makes sense only when the rest of the window is sound. We measure the unit, order a new one with the right spacer and glass package and replace it in your sash. If the window is old or the frame is failing, we discuss a full replacement as the better choice.

Why units fog

Spacers, seals and sealant wear over time, and temperature swings stress them. Once the seal fails, moisture gets in.

Replace the unit

If the sash is sound, a new sealed glass unit costs less than a new window and clears the view.

When to replace the window

A very old window, a rotted sash or a worn frame may call for a full replacement instead.

Upgrade the glass

A new unit lets you add low-E coatings or gas fill, so the repaired window can perform better than it did.

Questions

Foggy Window and Glass Unit Replacement FAQ

Can I wipe off the fog?

No. The moisture is between the panes, so only replacing the glass unit clears it.

Do I need a whole new window?

Not always. If the frame and sash are sound, a new glass unit may be enough.

How long does it take?

A unit is made to size, so it can take a week or more to arrive. Installation is quick.

Will fog come back?

A new unit has a fresh seal. A sound frame and good drainage help it last.

Can I upgrade the glass?

Yes. We can specify low-E coatings and gas fill in the new unit.
