Condensation causes and solutions – FIX from CR Smith

30/11/20

Condensation on windows, along with the damage that can be caused, is a problem that can occur to any kind of building or home. It can occur on the inside, outside or between the panes – the location can mean the difference between a simple DIY fix or calling in the experts.

If the condensation is forming on the inside pane of the window it means the temperature of the glass is too low in comparison to the water vapour content in the room. Modern advances to home comforts are great at helping create warmer homes, however, it also tends to mean there is less ventilation and air changes. This results in the water vapour that is produced by normal living activities not being able to escape as it would have before.

The question is how to reduce the condensation without sacrificing the benefit of increased comfort. The key is ventilation. Opening either the window or the trickle vents at least once per day will help combat the issue. If you either don’t have trickle vents or they are broken/not working, FIX from CR Smith may be able to help replace or install them to your existing windows.

If the condensation appears between the two panes of glass it means the seal has failed. This results in a less efficient window that spoils your view. Some companies claim to be able to repair this which may appear to work for a short period of time, however, the underlying issue of the seal that binds the glass together breaking down still exists. Therefore the problem will occur again!

To ensure a long-lasting repair the glass unit needs to be changed. We can replace the unit at a fraction of the price of a new window and will leave you with a 12-month guarantee and an efficient window once again. It also doesn’t matter how old the window is or if you have a uPVC, aluminium or timber window, FIX from CR Smith can solve the problem.

Finally, if you are finding condensation on the outside of your window it actually means your windows are very efficient and working well by preventing heat loss. Unfortunately, there is nothing that can be done in this particular case, it should only happen in clear, cold conditions with relatively high humidity.
