A damaged window should be repaired by an expert to ensure that you get the correct seal and the optimum energy efficiency.

If there's any indication of corrosion, these clips should be replaced with new ones. If the window is made of wood the glazier points may be reused if still intact.

The next step is to prepare the surface of the frame for re-glazing. Apply a continuous strip of compound to the recess using a caulking tool. Use a high-quality putty such as glazier's compounds that is available in a cartridge or conventional compound sold in a can. Let it dry before reinstalling the glass.

Condensation

Draughts

This is a simple problem to fix and windows can be swiftly repaired by professionals using the right tools. The specialist will use tools designed to push the new seals into position and it is usually faster than trying to do it manually. The tools also have a pointed tip which can be useful for pushing seals into the corners.

Broken Seals

Double-glazed windows are secured by window seals or insulation gas. A variety of factors can cause them to break, such as weather conditions, age and power washing. It's essential to be aware of what signs are and how to repair them.

When a window seal breaks it allows moisture to enter between the two glass panes, causing fog. It's a frequent issue and it can cause the window to look visually distorted. Once the seal fails, argon and other inert gases are lost from the window, decreasing the glass's insulation properties.

A professional glazier can replace a broken window seal with a brand new one. However, this could be expensive and may not solve the fog issue completely. Certain companies offer defogging solutions that involve putting a special vacuum pump in the window frame to remove the moisture and make the glass clear. However, this method is not foolproof and doesn't replace any inert gas, and the fog can be re-applied.

A glazier may also replace the entire IGU (insulated glass unit) when it's beyond repair. This is the most cost-effective method and can be a great choice if you are looking for a long term solution.
