How long does double glazing last? (and 4 signs it may need to be replaced)

Last Updated: 15 January 2024

On average, double glazing lasts around 20 years, though this isn’t an exact science. Depending on various factors, double glazing can last as long as 35 years or as little as 10. For those wanting to invest in this type of window, it’s important to understand the factors influencing the lifespan of double glazing.

Factors Affecting Double Glazing Longevity

  1. Quality of Materials: The durability and quality of the materials used in double glazing significantly affect its longevity. High-grade materials can withstand environmental factors better and last longer.
  2. Installation Quality: Expert installation ensures that the double glazing is fitted correctly, which can extend its lifespan. Poor installation can lead to issues like leaks and draughts, reducing longevity.
  3. Exposure to Weather: Double glazing in areas with harsh weather conditions may deteriorate faster. Regular exposure to extreme temperatures, heavy rain, and strong winds can impact the performance and lifespan of double glazing.

Choosing a reputable window installer in Cheshire, such as Reddish Joinery, ensures high-quality materials and professional installation.

Identifying the Need for Double Glazing Replacement

  1. Condensation Between Panes: Condensation inside the two panes of glass indicates seal failure, which can lead to mould growth and reduced insulation efficiency.
  2. Noticeable Draughts: Draughty windows suggest a failure in the weather sealing, leading to increased energy bills and discomfort in your home.
  3. Visible Damage: Significant damage to the glass or frame can compromise the insulation properties of double glazing.
  4. Operational Issues: Difficulty in opening or closing windows can be a safety hazard and indicates that the windows may need replacement.
