How do you tell if there is a crack in the seal

The seals in double-glazed windows help make your home energy-efficient by keeping the cold air out and letting warm air in. However, they are prone to wear and tear and could be damaged over time. If they do, it can result in draughts and condensation between the panes of glass. It is important to replace the window seals if necessary and check them regularly to ensure your windows are in a good condition.

It is recommended to have your windows professionally installed and to keep them maintained.

uPVC seals are an essential part of double glazing. They play a crucial part in keeping your home draught free and energy efficient. These seals are made from rubber or silicone strips which fit between the frame of the window and the glass to form an airtight seal. In winter the seals keep warm air in, and in summer they prevent hot air from getting into the building. However, they are susceptible to being damaged by a variety of reasons, such as normal wear and tear and extreme weather conditions or a poor installation.

It is possible to fix the damaged window seal yourself, but it is important to know what you are doing before you begin. First, you will need to determine the where the seal broke.
