All windows have a shelf life, no matter what they're made of. On average, windows typically have a lifespan of 15 to 20 years. Knowing when it's time to replace them is crucial to maintaining the comfort and efficiency of your living space. Glassfast are here to help with your window replacements and emergency window repairs in Devon and surrounding areas. Here are some key signs that indicate your double glazing may need replacing. If you notice any of these on your windows, get in touch with us today.

Condensation Between Panes
Condensation is the transformation of vapor or gas into liquid. It is one of the most apparent signs that your double glazing needs replacing. Condensation forming in the space between the glazing means a failure in the seal, compromising the insulating gas between the layers. Not only does this impact energy efficiency, but it also detracts from the visual appeal of your windows.
Draughts or Cold Spots
If you've been struggling to keep your home as warm as usual, then inspect your windows for draughts or cold spots. Draughts originating directly from the windows suggest worn-out seals. If draughts are noticeable between your property's brickwork and windows, it indicates potential wear in the sealants.


Visible Damage to Frames or Glass
Obvious physical damage, such as cracks, chips, or warping in the frames or glass, is a clear indicator that your double glazing is no longer performing at its best. Over time, wear and tear can compromise the structural integrity, affecting both the aesthetics and functionality of the windows. Glassfast offer emergency window repairs in Devon, if your window is damaged get in touch with us today.
Difficulty Opening or Closing
If you have difficulty when opening or closing your windows, it may indicate issues with the hinges, locks, or the overall functionality. Windows should open and close easily. Any difficulty not only causes inconvenience, but also poses safety risks. Especially in emergencies like fires. The cost of not being able to escape through a malfunctioning window could be much higher than the price of getting them replaced.


Excessive Noise Infiltration
Double glazing is designed to reduce noise infiltration from the external environment. If you find that your windows are no longer effective in minimising outside sounds, it may be time to consider replacements.
