Asbestos can be found in any house or building built before the year 2000 as it was widely used in a variety of building materials.
If asbestos materials are in good condition, and in a place where they are unlikely to be disturbed, then they should not cause any harm.
It is only when the materials are damaged or disturbed, so that fibres are released, that asbestos can become a danger.
Homeowners are responsible for any asbestos in their homes. If you know that you have asbestos in your home and are planning some home improvements or maintenance, you must inform builders, contractors etc. before they start work. Even minor damage, such as drilling a hole to hang a picture can produce many fibres
