Asbestos in Garages and Outbuildings: A Common Hidden Risk

When people think about asbestos in the home, they often picture ceilings, insulation, or pipe lagging inside the property. However, one of the most common places asbestos is found is actually outside the main house, in garages, sheds, and other outbuildings.

Many UK homes built before 2000 include garages or garden structures that were constructed using asbestos-containing materials. Because these areas are used less frequently, asbestos can sometimes go unnoticed for years.

Why Asbestos Was Used in Garages

Asbestos was widely used in building materials because it was strong, durable, and resistant to heat and weather. In garages and outbuildings, it was commonly found in cement-based products, particularly:

• Garage roof sheets
• Wall panels and cladding
• Soffits and fascia boards
• Drainage pipes and flues

These asbestos cement materials were popular because they were affordable and long-lasting, which is why many are still in place today.

When Asbestos Becomes a Concern

In many cases, asbestos cement materials are relatively stable and can remain in place without causing immediate problems. However, issues can arise if the material becomes damaged, deteriorated, or disturbed.

For example, risks may increase if:

• A garage roof starts to crack or break down
• Sheets are drilled into during DIY work
• Old structures are dismantled or demolished
• Weather damage weakens the material over time

When asbestos-containing materials are disturbed, fibres may be released into the air, which is why it’s important to approach older structures with caution.

Renovating or Removing an Old Garage

Garages and sheds are often renovated, replaced, or removed during property improvements. If your outbuilding was constructed before 2000, it’s important to consider whether asbestos could be present before starting work.

An asbestos survey can help identify any asbestos-containing materials and confirm the safest next steps. In some cases, the material can remain in place and simply be monitored. In others, professional removal may be recommended.

Taking the Right Next Step

If you suspect asbestos may be present in your garage or outbuildings, the best approach is to seek professional advice before carrying out any work. Trying to remove materials yourself can be dangerous and may create unnecessary risks.
