Steps
Put lids on pans when you cook. Boiling water without a lid sends a lot of steam into the air, which ends up on your windows.
Switch on the kitchen extractor fan while cooking and leave it running for a few minutes afterwards. Check it pulls air properly, not just makes noise.
Run the bathroom extractor fan during and after showers and baths. Keep the door closed so moist air leaves through the fan, not into other rooms.
Dry clothes outdoors or in a well-ventilated room. Avoid drying washing on radiators in living rooms and bedrooms where the moisture has nowhere to go.
Open trickle vents on your windows and open windows briefly each day to swap moist air for fresh air. Short bursts of full opening work well.
Keep rooms from getting very cold. Warm surfaces hold less condensation, so heat rooms evenly rather than letting them drop sharply.
Wipe condensation off glass and sills each morning before it runs down. Standing water damages seals, paint and plaster over time.
Use a dehumidifier where humidity stays high, especially if you dry clothes indoors. Empty the tank and keep doors closed while it runs.
Check for rain getting in. If damp appears around one window only, or after storms, look for gaps, failed seals or leaking gutters above.
Tips and common mistakes
A dehumidifier helps with moist air but will not fix a leak or replace proper ventilation.
If condensation shows on one window only, suspect a fault with that window rather than general humidity.
Mould on sills and seals means you left the moisture too long, so wipe daily and improve airflow.
Cooking, showering and drying clothes are the biggest indoor moisture sources, so tackle those first.
Questions
Why do my windows get wet every morning?
Warm, moist air inside your home hits cold glass overnight and condenses. Reducing moisture and improving ventilation usually fixes it.
Does a dehumidifier stop window condensation?
It lowers indoor humidity, so it can help a lot, especially when clothes are dried indoors. It will not fix a leak or replace ventilation.
Should I open windows in winter to stop condensation?
Yes, short bursts of opening windows or using trickle vents let moist air out. You do not need to leave them open for long.
