Why do my windows get misty?

We covered part of this in our blog Steamed up and misty windows and our professionals will be able to ensure the most cost effective solution to your failed glass. To understand better, your Double-Glazing unit has two panes that are sealed in a unit and then filled with gas. The gas inside creates an insulating barrier, sometimes the barrier seal breaks and then moisture can penetrate the gap and then the windows can start to mist up. The seal could have failed for a number of reasons, physical damage, poor installation, or simply age.

Where is the mist on your windows?

It is important to recognise that mist on the outside of your windows is perfectly normal, and means they are performing how they should be. This happens because when the temperature outside drops, like in springtime or autumn it reacts with the heat on the inside of the house and creates condensation.

How does it affect my energy bills?

When you find mist on the inside of your panes, it means your double glazing is no longer functioning to the best of its ability and the seals are broken and this will affect the efficiency of your windows keeping the warm air in. This means you will have to heat the house longer to maintain the desired heat in your home, thus costing you more.

Do you have to change the frame as well?

If there is no physical damage to the frame, it is very unlikely we will need to change the frame unless they are so old, it would be advantageous to do so. We can discuss these options when looking at the budgets and current condition of your frames.
