3 Easy Ways to Stop Condensation on Windows
1. Condensation happens when warm, moist air hits cold glass. The simplest fix is to let that damp air escape!
Open window trick: Even 10–15 minutes a day makes a huge difference — especially after cooking, showering or drying clothes inside. Use trickle vents: Most modern windows have tiny top vents — leave them open year-round. You won't feel a draft, but moisture will escape. Close doors: Keep bathroom and kitchen doors closed while using them — stops moisture spreading through the whole house.
2 — REDUCE EXCESS MOISTURE AT SOURCE
Stop the water getting into the air in the first place! Dry clothes outside if you can: If you MUST dry indoors, put them in one room, shut the door, and open a window. Cover pans when cooking: Stops steam filling your kitchen — and saves energy too! Wipe windows down: If you see mist, wipe it away with a towel. Don't let water sit on the frames — that's how mould starts.
3 — KEEP TEMPERATURES CONSISTENT
Big differences between inside and outside = condensation. Heat evenly: Don't let rooms get freezing cold then blast them with heat — keep a steady, low background temperature everywhere. Curtains open at night: Heat gets trapped behind closed curtains and meets cold glass — leave them open a little so air circulates. Dehumidifier (optional): If condensation is really bad, a cheap dehumidifier pulls moisture straight out of the air — set it to 50–60% humidity.
BONUS QUICK TIP:
Warm air holds more water than cold air. So if your house is warm AND damp → that mist WILL appear. Ventilate + reduce moisture + steady heat = problem solved!
