Insulated Glass Unit Replacement

Replace foggy, failed double-pane glass units and restore clear views and better comfort.

Double-pane windows are built as sealed units with a gap between two sheets of glass. When the seal fails, moisture gets in and the glass looks foggy or streaked, and the insulating gas can escape. You cannot clean this away, because the moisture is trapped between the panes. Replacing the sealed glass unit restores a clear view and usually brings the window back to its original comfort, without the cost of replacing the whole window.

We measure the sealed unit, check the thickness, the spacer type and any special features such as low-E coatings, argon fill, tempering or decorative grids. We order a new unit to match, remove the old one and install the new unit into your existing frame with new glazing. We test the fit and clean the glass and the frame.

Reading your unit

We check the overall thickness, the spacer, the coatings and whether the glass is tempered. A good match helps comfort and appearance.

Options and upgrades

You can often keep the same specification or upgrade to low-E coatings, gas fill or laminated glass for sound and safety.

Frame condition

The frame must be sound. If a sash is rotted or warped, we tell you before we replace the glass.

Install and seal

The new unit is set with fresh glazing or gaskets so it seals properly and stays dry.

Questions

Insulated Glass Unit Replacement FAQ

Why is my window foggy?

The seal around the double-pane unit has failed and moisture has entered the gap between the panes.

Can foggy glass be cleaned?

Not from the outside. The moisture is inside the sealed unit, and the unit needs to be replaced.

How long does replacement take?

Units are made to order, often within a week or two. Installation is usually quick.

Will the new glass match my other windows?

We match thickness and coatings as closely as we can. Color can vary slightly between makers.

Does the sash need replacing?

Not unless it is damaged. We inspect it first.
