What causes damp?

Dampness inside a home usually comes from one of two sources: either it seeps in through the building’s materials, or it’s caused by condensation. Let’s dive into what each of these means:

  1. Penetration damp is when water from outside gets into the house through the walls, roof, or windows. This could happen because of rain getting through a crack or a broken tile, for example.
  2. Condensation damp happens when the air inside the house gets too moist and the water in the air turns into water droplets on colder surfaces like walls or windows. This is common in places like kitchens and bathrooms, where there’s a lot of steam.
