Condensation on your windows every morning? The 5-minute routine that protects your frames
Sound familiar? You open the curtains on a cold autumn morning and the glass is covered in condensation. Small droplets gather at the bottom of the pane and run down onto the sill. It looks harmless, but condensation on windows is one of those small signs in the home that's worth taking seriously. Moisture that's left sitting day after day can, over time, create the conditions for mould and wear down the window frame.
The good news is that it doesn't take much to prevent it. With a set routine of around five minutes each morning, you can keep panes and frames dry all winter. Here's how we'd do it.
Why do windows steam up in autumn and winter?
The air inside a home always contains water vapour. It comes from perfectly ordinary everyday things: sleeping and breathing, cooking, showering, washing up and drying clothes indoors. In summer we rarely notice it, because we air the house more and the windows are warm.
When it gets cold outside, the glass in the window gets cold too, and it becomes the coldest surface in the room. When warm, humid air meets the cold glass, the air cools down and the water vapour turns into tiny droplets. It's exactly the same thing that happens when a cold glass of water "sweats" on a warm day. That's why you mostly see condensation on the glass in the morning after a cold night, and especially in the bedroom, bathroom and kitchen.
A little condensation now and then is completely normal. It's when the moisture stays put that it can become a problem for frames, seals and paintwork.
The morning routine: 3 steps in 5 minutes
Make it a habit, just like putting the coffee on. The sooner you remove the moisture, the less time it has to soak into the frame.
1. Squeegee the water off the glass
Start at the top of the pane and pull the water downwards in calm, overlapping strokes. A squeegee gathers the droplets far faster than a cloth on its own, and you avoid smearing the moisture around. Our Shower Squeegee is made for exactly this kind of job. It has an ergonomic handle with a non-slip grip and quickly clears water from most smooth surfaces. It's not just for the shower door, but also for mirrors, tiles and the windows around your home. Hang it by one of the windows that steams up the most, so it's always within reach.
2. Dry the sill and bottom rail with a microfibre cloth
The water the squeegee pulls down ends up at the bottom of the pane and on the sill. This is where the moisture mustn't be left sitting. Wipe the bottom rail, the sill and the corners thoroughly with a dry cloth. For large windows and lots of panes, a big cloth like our 50 x 70 cm microfibre cloth is handy, while the smaller 35 x 35 cm microfibre cloths (2-pack) easily get into corners and narrow frames. It's a good idea to keep one cloth in every room that steams up.
Remember to hang the cloth up to dry afterwards so it's ready for the next morning, and wash it regularly.
3. Air the room with a cross-draught
Finally, the humid air needs to get out of the house. Ideally, open windows at opposite ends of your home to create a cross-draught. A common recommendation is to air the house for 5-10 minutes a couple of times a day. A short, effective cross-draught replaces the air without chilling walls and furniture, so it's better than leaving a window ajar all day.
More good habits against window condensation
Keep an even temperature
Cold rooms and cold surfaces mean more condensation. It can be tempting to turn the heating right down in the bedroom or in rooms you don't use, but then walls and windows get cold and moisture settles more easily. Instead, keep an even level of warmth throughout your home, and close the doors to the cooler rooms.
Give the air room by the window
Heavy curtains drawn all night, and large furniture or plants right in front of the window, make it harder for warm air to reach the glass. Open the curtains in the morning, and try to keep the radiator under the window clear.
Tackle moisture at the source
Use the extractor fan when you cook, and put lids on your pans. Air the bathroom after a shower, and squeegee the water off the shower wall and tiles so the moisture doesn't linger in the room. If you dry clothes indoors, try to do it in a room you can air well.
Look after the frame
Check the frame every now and then, especially at the bottom and in the corners. Keep it clean and dry, and keep an eye out for flaking paint, cracks or discolouration so you can deal with them in good time. A clean, well-maintained frame is easier to keep dry.
Frequently asked questions about condensation on windows
Why is there condensation on the outside of my windows?
Condensation on the outside of the glass in the morning is common with newer, well-insulated windows. Because the window keeps the heat inside, the outer pane gets cold, and moisture in the outdoor air can settle on it. It's not a sign of damp in your home, and it usually disappears during the morning.
What does it mean if there's condensation between the panes?
You can't wipe away condensation between the two layers of glass in a double-glazed unit. It usually means the seal has failed. In that case it's a good idea to talk to a glazier or window specialist.
Does turning down the heating help prevent condensation?
No, usually quite the opposite. Cold rooms and cold surfaces mean more condensation. What helps is even warmth combined with short, effective airing, and drying panes and frames when they steam up.
Small habits, big difference
Condensation on windows is a natural part of winter in the north, but it doesn't have to become a problem. With a squeegee, a good microfibre cloth and five minutes in the morning, you keep panes and frames dry and help stop moisture from settling.
