Can a foggy double-pane window be fixed without replacing the whole window?

Usually, yes. Legacy Glass replaces the failed insulated glass unit and keeps the existing frame, for homes and businesses in Iowa City, Cedar Rapids, and the rest of the Corridor. Replacement units are made to order and usually arrive in 1 to 3 weeks, depending on the project.

Why windows fog

A double-pane window is two panes of glass sealed together. When the seal fails, moist air gets between the panes and condenses, leaving fog or streaks you cannot wipe away.

Glass-only replacement vs. full window replacement

If the frame is still in good shape, we replace only the insulated glass unit and keep the frame, which costs less than replacing the whole window.

If the frame is damaged, we also offer full window replacement.

Lead time

Insulated glass units are made to order for your opening. Most arrive in 1 to 3 weeks, depending on the project, and we install them as soon as they arrive.
