If you have wooden frames, you can purchase points for glaziers from a hardware store to install on the edges of your new pane.

The lintel that is above the window can be the source of leaks. The builders who constructed the house might not have realized the importance of allowing the lintel drain properly, or they could have covered it in concrete, which left a gap in which rainwater could enter and pool around and cause dampness or rot to the wood. The builders may have an angled fascia board above the windows to ensure water is directed correctly. This will stop water from getting into the building.

Another potential leak could be the gap that exists between the glass panes of a double-glazed unit. It's possible that the gas argon or krypton that should be between the glass panes to create insulation has escaped of the windows due to the seal being worn out.

The majority of double-glazed windows feature spacer bars that sit between the two glass panes. The spacer bar is filled with desiccant which sucks up any moisture that might be present, thereby preventing it from reaching the glass panes and creating condensation.

Some IGUs contain argon, a gas that stops heat from escaping the home and saves you money on energy costs.

If one of the IGUs is damaged, a replacement pane can be purchased from a window repair maker and fitted to the frame. This is normally far cheaper than replacing the entire window and is cheaper for most households.
