When a window pane is damaged it loses its insulation properties and may cause drafts. If the dividing muntins also broken it can cause moisture to leak through the glass panes resulting in condensation, mould and mildew and making your home less efficient in energy use. It is recommended to have an expert repair a damaged window in order to get the most effective seal and energy efficiency.

It's worth lubricating this tool's cutter with lightweight oil before you begin. This will prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to break the fragments. They should be removed relatively quickly.
After the glass has been removed, scrape off any old glazing compound from the recess area of the frame. This will reveal the glazier's facets and metal clips that hold the pane in place. If there's any sign of corrosion, the clips must be replaced with new ones. If the window is made of wood the glazier points can be reused if they're still in good shape.
You'll need to prepare the surface of the frame to be re-glazed. With a caulking gun apply a continuous ribbon of compound along the inside edge of the recess. Use a high-quality putty such as glazier's compounds that comes in a cartridge, or a standard compound that comes in a tin. Let it dry before inserting the glass.

In the process, they'll check for the presence of mildew, mold or damage growth and carry out a draught-proofing process to ensure your windows are fully efficient and energy efficient again.
Draughts
Rubber seals may wear out over time and create drafts between your two panes. This is typically a simple problem that can be fixed by replacing the gaskets and this will result in a solid and airtight seal once again.

The unit is comprised of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal has blown, water vapour will enter your room via the gap. This can cause condensation between the glass panes which can't be sucked out.
This is a simple issue to repair, and windows can be quickly repaired by professionals using the right tools. The specialist will use an instrument designed to push the new seals in place and is generally faster than attempting to do it manually. These tools have an angled tip that can be used to push the seals into corners.

Broken Seals
Double-glazed windows are secured by window seals or insulation gas. They are susceptible to damage due to various factors, such as age, weather conditions, and power washing. It is essential to recognize the signs and how to repair them.
When a window seal breaks, it allows humid air to enter between the two glass panes, creating fog. It's a frequent issue and it can cause the window to look visually disoriented. Once the seal fails, argon and other inert gases are removed from the window, thereby reducing the glass's insulating qualities.
A professional Glazier can replace a damaged window seal with a new one. However, this is expensive and may not solve the fog problem entirely. Certain companies offer defogging, which involves putting a vacuum pump inside the window frame to remove moisture and clear the glass. However, this method is not foolproof and does not replace any inert gases, so the fog could come back.
If the IGU (insulated unit) is damaged beyond repair, a glazier could replace it. This is the most cost-effective option and can be a great option if you're looking for a long-term solution. It's best to select a company who offers warranties on replacement windows. This will ensure that any issues you might face are covered.
