To stop condensation permanently, you need to reduce indoor humidity and improve ventilation by using extractor fans, opening windows regularly (especially after showers/cooking), avoiding indoor drying of clothes, and potentially installing a whole-house ventilation system like a PIV system for a long-term, effective solution. Consistent heating and ensuring good airflow around windows also helps, as colder air holds less moisture, reducing condensation risk.
Condensation happens because rooms get too cold, they fluctuate between cold and hot, and there is excessive moisture from cooking, washing and expiration. The biggest causes are showering, drying clothes on radiators and boiling pans. Underlying issues of damp can also be a persistent problem.
Should You Wipe Condensation Off Windows? Yes, wipe off any condensation on your windows with a soft microfibre cloth. It's one of the first things you should do. Not only does it protect your windows and sills, but it also helps maintain healthier indoor air quality by stopping mould from growing.
Use a dehumidifier , and proper heating , that is the only way to keep humidity and condensation away.
Dehumidifiers are a powerful weapon when it comes to tackling condensation, damp and mould. But it's important to use them correctly to maximise their potential.
Keep windows closed
It's good practice to open a window to ventilate the house and reduce humidity levels after cooking or showering. But running a dehumidifier with the windows open will undo all its hard work.
Yes, a bowl of salt can help reduce condensation because salt naturally absorbs moisture from the air (a process called deliquescence), making the surrounding area drier and preventing water droplets from forming on windows or other surfaces. Placing a bowl of salt, especially rock salt, on a windowsill can help control humidity and reduce dampness, but you'll need to replace it as it clumps up with absorbed moisture.
Signs of excessive HVAC condensation
The Snake Plant is perfect for a bedroom as it absorbs water vapour at night, helping to tackle nighttime condensation on windows. Also, the plant will remove carbon dioxide from the air during the night and produce oxygen which is needed for a good night of sleep.
How to Stop Condensation on Windows Overnight in Winter
THE TEMPERATURE OF YOUR HOME
Cold air is more likely to deposit droplets of condensation around your home. Air is like a sponge, the warmer it is, and the more moisture it will hold. Heating one room to a high level and leaving other rooms cold makes condensation worse in unheated rooms.
Keep your home adequately heated
Try to keep your home suitably heated. It usually helps to have a low background temperature of at least 15 degrees in all rooms. By doing this you are less likely to have condensation dampness as the warm air holds more moisture than cold.
Sleeping in a damp room can lead to serious health issues, including respiratory problems, allergies, skin conditions, and a weakened immune system due to the presence of mould and excess moisture.
Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air, but be sure that the appliances themselves don't become sources of biological pollutants. Raise the temperature of cold surfaces where moisture condenses. Use insulation or storm windows.
Condensation occurs when warm air collides with cold surfaces, or when there's too much humidity in your home. When this moisture-packed warm air comes into contact with a chilly surface, it cools down quickly and releases the water, which turns into liquid droplets on the cold surface.
The 3-minute rule is a simple but important guideline: wait at least three minutes after turning your air conditioner off before turning it back on. That short pause gives the refrigerant pressure in the system time to equalize.
Condensation: Dew, Frost, Fog, Mist and Clouds. The transformation of water vapour into liquid is known as condensation.
Baking soda is an inexpensive and versatile option that effectively dehumidifies small spaces, like cabinets.
So, while vinegar can be used to wipe away and prevent the build-up of water spots and stains from existing condensation, it does not actually eliminate the chances of condensation forming in the first place. Similarly, there are several other myths about how to stop condensation on the inside of windows.
DampRid uses calcium chloride salt, which gets the humidity way lower. Rock salt only gets the humidity down to 75%RH.

Keep curtains open in bedrooms at night
Keeping curtains open at night means the glass temperature will stay closer to the room temperature so condensation won't form. If it's not practical to keep curtains open, changing them to thinner curtains will still make a difference.
Extracting moisture from the air to reduce the humidity level, dehumidifiers help you maintain the optimal humidity in your home to protect your home and health.
