If a window seal fails the insulating gases get released, making the windows less efficient in saving energy.

This is a major issue for homeowners since it means they're losing energy efficiency which can result in higher costs to heat their homes.

The misting that occurs in your double glazing is due to the temperature difference between the glass panes, and the air outside. This causes moisture to build up within the window, which causes a gap to form between the panes. This is also referred to as a "blown window".

Replacing the blown window by a new one will increase your home's energy efficiency and to save money on heating bills. A new window will seal the gap, stopping warm and cold air from entering and leaving your home. This will ensure that your heating stays where it should.

This could be caused by weather conditions, such as extreme temperatures and is usually resolved by wiping the frames with cold water. This reduces the size of the frame, making it easier to open and close the window or door again.

You can also do this yourself. Sand and scrape the rabbets which fit the window into frame until they're just naked wood. Paint them with an external primer. Use putty to fill in the gaps left by the rabbets. Be cautious not to smooth the surface as you want it to be as sturdy and secure as possible.
