Condensation

Waking up to wet windows?

Finding condensation on your windows can be frustrating – and it’s natural to wonder whether there’s something wrong with them.

The reassuring news is that condensation is extremely common, particularly during the colder autumn and winter months. In many cases, it isn’t a fault with your windows at all.

This guide explains why condensation happens, what the different types of misting can tell you, and some simple things you can do to help reduce it in your home.

Why does condensation form?

Everyday life creates moisture. Cooking, showering, drying clothes and even breathing all release water vapour into the air inside your home.

When warm, moisture-filled air reaches a colder surface, such as your window glass, it cools. The moisture then turns into the small water droplets you see on the glass.

That’s why condensation is often most noticeable first thing in the morning, particularly in bedrooms, kitchens and bathrooms.

Where is the condensation?

Where the moisture appears can tell you a lot about what’s happening.

Condensation on the inside of your windows is usually caused by excess moisture in the room meeting the colder glass. Improving ventilation and reducing humidity can often make a significant difference.

Condensation on the outside of your windows can actually be a good sign. Modern, energy-efficient glazing keeps more warmth inside your home, meaning the outside pane stays colder. In certain weather conditions, moisture can therefore form on the external glass.

Condensation between the panes of glass is different. This can indicate that the sealed unit has failed, allowing moisture to enter the space between the panes. If this is happening, it’s worth having the glazing checked.

How can you reduce condensation?

A few simple changes can help keep moisture levels under control. Use extractor fans when cooking or showering, ventilate rooms regularly, avoid drying wet clothes indoors where possible, keep trickle vents open and try to maintain a reasonably consistent temperature throughout your home.

Wiping away excess condensation when it appears will also help prevent moisture sitting around window frames and surrounding surfaces.

Still concerned about your windows?

We’ll help you understand what’s happening and, if something does need attention, explain the options clearly – without making the problem bigger than it needs to be.
