Frequently Asked Questions

If your window problem is minor then you might be able to repair the window yourself, however, it is always best to have the window looked at by an expert to determine if it can be fixed or will need a replacement window.

You can tell if you need new or replacement windows by checking through these statements:

  • My windows don’t open and close easily. In this instance, the window frames could have warped, started to rot, or maybe the wrong size.
  • My windows are drafty. This issue occurs when a window doesn’t shut properly, the locking system no longer works, or the windows are single glazed. Windows with double glazing are significantly more energy-efficient than single glazed windows, so you could end up saving quite a lot of money on your heating bills by switching.
  • You can hear outside noise from inside and the window is shut. This is usually a sign that the windows are very old and will need replacing.
  • Your window is leaking. This is a sign that the seals around the glass have gone, replacing existing windows with new double glazed windows will be the most cost-effective option.
  • My windows are over 15 years old. We always recommend asking an expert if an old window is still in good enough condition.


The average double-glazed unit lasts 25-30 years before its performance standards begin to drop. In some cases, they've been known to last up to 40 years.


It depends how many windows you’re are replacing as to how long it will take to install as well as the type of window being replaced

On average, each window takes anything from an hour to 3 hours to install. The time it takes to install the window will be different depending on the size and type of window.
