Are Your Windows Getting Condensation Inside Them?

Window with condensation

If you notice condensation on the inside of your double glazed windows, you may begin to worry. Questions could pop up inside your head, like “is my home damp?” and “are my windows okay?” It is perfectly normal to worry about such things, of course, since your house is where you live and you want to live in comfort!

So, without further ado, we’re going to discuss some of the reasons that you may be finding condensation on the inside of your windows; and hopefully provide you with some solutions, too!

Ventilation Issues

Ventilation is probably the biggest cause for condensation on the inside of windows and doors. It is no secret that water gets into the air through seemingly innocent, everyday things. Breathing, bathing, cooking, and even talking release water vapors into the air. On top of this, the busier your home, the more vapor is likely to be released into the atmosphere.

It is quite simple to check if the condensation on the inside of your double glazing is caused by ventilation issues, simply crack open a window or two and see if the condensation begins to go away. If it does, you’ve found your culprit.

If lack of ventilation is the reason for condensation within your home, at least you have a reason to be happy: your home is almost air tight, meaning you don’t have to put up with the unpleasantness of drafts and your heating bill should be lower, too!


It may seem extremely obvious, but we all have moments where we struggle to see an obvious answer that is right in front of our noses. Plenty of appliances around the house cause condensation, and if they happen to be at work near to your double glazed windows, then there’s a chance that the condensation that you see on your windows is actually being caused by your household items.


Probably the most obvious offender is the humble kitchen kettle. It may help you wake up in the morning with a lovely cup of tea, but if it is placed too close to a window or door, the steam it releases as it boils your water will gather on the PVC and panes in close proximity.

Tumble Drier

The whole point of a tumble drier is to remove moisture from the clothes inside it. Of course, driers aren’t magic, all of that moisture has to go somewhere. Via ventilation pipes, the moisture is drawn away from the tumble drier’s payload and into the atmosphere via a tube of some form or another. Any condensation gathering near to the opening of this tube is likely being caused by the drying of clothes and can be alleviated by having your drier vent leading to an area outside of the house.
