If your home was built prior to the 1990s, asbestos-containing materials are very likely present. Asbestos was used in more than 3,000 different building products. The only way to be certain is to have a trained professional walk through the building identifying suspect materials. Once suspect materials are located, they must be tested by an accredited laboratory to confirm whether asbestos is actually present.

There are two important situations where testing is essential:

1. Before any renovations, construction, or demolition in areas that have not been completely renovated since 1990. If you are unsure, contact a local asbestos professional before starting any such project.

2. If there is any breakage, cracking, or damage to materials that might contain asbestos. Damaged materials have a high likelihood of releasing fibres. If materials are intact, undisturbed, and not damaged in any way, they are likely safe until renovation or demolition is planned.

If the suspect materials are undisturbed and intact, you generally do not need to leave the building. However, if materials are damaged, cracked, or deteriorating, it is best to have occupants leave the affected area and restrict access until an inspection confirms whether asbestos is present.

If asbestos-containing materials are confirmed but are undisturbed and in good condition, they are generally considered safe. In some situations, containment measures such as binding agents, signage, or encapsulation may be used until renovations are completed. While asbestos abatement is always the preferred long-term solution, it is not always immediately necessary or feasible when materials are stable.

If abatement is required, all building occupants must vacate for the entire duration of the removal work. Re-entry is only permitted after independent air clearance testing confirms that fibre levels are below acceptable limits. In larger commercial buildings, operations may continue in areas outside the sealed containment zone, with regular air quality monitoring throughout.

If you are not completing renovations and there are no damaged building materials, there is no immediate need to be concerned about asbestos exposure. However, before any planned renovation or if you notice damaged materials, professional inspection and asbestos testing is essential.
