What causes condensation?

Condensation inside a home happens when warm, moist air from everyday activities meets cooler surfaces like windows, doors, or walls. This warm moisture comes from things we do all the time, such as taking a shower, doing the dishes, drying clothes inside, or even when we’re cooking. These activities heat water up and turn it into vapour, which is just water in its gas form floating in the air. When this vapour touches cooler surfaces, it changes back into liquid water, which we see as condensation.

If a house doesn’t have good airflow or if it’s not well-insulated, condensation can become a real problem because the moisture has nowhere to go. This can make the house damp, which isn’t good for the building or for the people living in it.
