How to Repair Double Glazed Windows Double-glazed windows typically come with either 10 or 20 year warranties, so make sure to check what cover you have. Repairing your double glazing is less expensive than replacing it and could help you save energy and money on your bills too. If your double glazing is misting it is most likely that the sealant between the glass panes has failed. This is usually the case when windows are worn or damaged and can be costly to replace. 1. Glass that has chipped or cracked A cracked or chipped double-glazed window is a typical issue that can cause condensation between the two glass panes in your home. In the majority of cases, it is necessary to replace the entire glass unit, particularly if both or one of the panes has been broken. However, if the frame is still in good condition, repairing a single glass pane can be an effective alternative. Repairing cracks is simple and fast with masking tape or duct tap. For superficial cracks like stress cracks that occur because of temperature differences one strip of tape covering both sides of the window should be enough. For more serious cracks, such as those caused by impact, it's recommended the tape be extended across the entire length of the crack to ensure it can hold the glass together. A solvent-based glass glue is another option for a permanent fix. It is typically applied to both the inside and outer surfaces and then spread using the help of a putty knife. This technique can take longer than using masking tape, however, it's more effective at stopping the cracks from spreading further. If the cracks are serious or have occurred over a long period of time it may be better to wait for a professional company to fix the windows as this will likely result in a more durable finish. If the cracks don't appear to be excessively severe and they aren't causing water leaks, it may be best to opt for quick solutions. They will help keep the cost down.

First, clean the glass surface using a damp cloth, and then allow it to dry completely.
