Double pane windows depend on the space between the windows to create an airtight seal. This helps to keep the heat in and keep the cold out. However, this seal can be compromised by a physical abrasion or exposure to extreme temperatures. This is why it's so important to fix cracks in double pane windows when they begin to appear.

To prevent the putty from cracking you can place a hot gun on it to gradually soften it. Once all the putty has been removed, you'll need clean and sand the grooves where the new glass will go.

If a double glazing window is broken the costs of replacing it could increase. Window repair companies charge between $50 and $80 an hour to remove and replace the window. The exact cost will depend on the shape, size and thickness of the window, and also the design and quality of the surrounding frame and the sash. The cost of repair will also depend on whether the window is single-hung or double-hung. Windows that are higher up or require access to the roof will cost more to repair as the repair technician requires additional equipment and safety precautions.
