Signs your windows need replacing


Draughts are one way to see if your windows are in need of being replaced. Not only are they unpleasant due to the discomfort that they cause, but they are also something that you will need to look into. By unwittingly letting cold air into your home through your windows, the likelihood is that you will need to compensate through your heating. This in turn would likely cause a rise in bills. Draughts will typically enter your home through cracks and gaps, so checking for these is also important.

In terms of double glazing, the most pressing issue when it comes to condensation would be if it is found in between the two glass panes. Condensation on the inside or outside of your windows is not necessarily a bad thing, but if it is in between then you will need your windows replaced.


Damage to your windows can cause irreversible problems down the line. The more damage there is to your window, the more likely it is that you will need a replacement. 


The performance of your windows is an important factor to keep an eye on. If you have single glazing installed then you may be more prone to performance issues. This includes security and energy efficiency from their limited heat retention, thus potentially causing condensation. It would typically be a good idea to look into replacing single glazing, particularly if it is more than 10 years old. In general, look out for any handles, locks or hinges that are broken as these can cause security issues and draughts.
