Is It Safe to Leave Asbestos in My Home If It’s Not Damaged? Auckland Homeowner Guide

Is It Safe to Leave Asbestos in My Home If It’s Not Damaged?

If you’ve just found out there may be asbestos in your home, the first thought is usually: “Do I need to rip it out straight away?”

The honest answer is: not always. In many Auckland homes, asbestos-containing materials can be left in place if they are in good condition, sealed, undisturbed, and unlikely to be damaged.

But — and this is the bit homeowners need to understand — asbestos is only “safe” while it stays locked into the material. Once it is drilled, broken, sanded, water-damaged, removed the wrong way, or starts falling apart, it can release tiny asbestos fibres into the air. That is where the health risk begins.

What Is Asbestos and Why Is It in Older Auckland Homes?

Asbestos was commonly used in New Zealand homes because it was strong, fire-resistant, cheap, and easy to mix into building products. Many houses built before the 1990s may contain asbestos somewhere.

Common asbestos materials found in Auckland homes include:

• Asbestos cement cladding
• Asbestos soffits and eaves
• Asbestos baseboards
• Vinyl tiles and old black adhesive
• Textured ceilings
• Asbestos roofing, including Super Six and Decramastic-style roofing systems
• Old fencing panels
• Pipe lagging and service ducts
• Contaminated soil around older buildings

The problem is that many of these materials look harmless. A sheet of old cladding or a soffit board may look like normal fibre cement. That is why proper asbestos testing is important before renovation, demolition, drilling, or removal work.

Is Asbestos Dangerous If It Is Not Damaged?

Asbestos is usually considered lower risk when it is:

• In good condition
• Fully sealed or painted
• Not cracked, broken, or crumbling
• Not exposed to weather damage
• Not being drilled, cut, sanded, scraped, or disturbed
• Away from areas where children, pets, trades, or tenants may damage it

For example, an asbestos cement soffit that is fully painted and sitting untouched may not need urgent removal. The same may apply to asbestos cladding or baseboards if they are solid, sealed, and not being affected by water or impact damage.

However, asbestos should never be ignored. It needs to be managed.

A good way to think about it is this: asbestos is not like a rotten fence paling you can leave until next summer. It is a hidden risk that needs a plan.

When Should Asbestos Be Removed?

You should seriously consider asbestos removal if the material is:

• Broken, cracked, or crumbling
• Exposed to weather and starting to deteriorate
• In an area being renovated or demolished
• Likely to be drilled, cut, scraped, water blasted, or sanded
• Inside a home where future trades may disturb it
• Around children’s play areas, gardens, driveways, or high-traffic spots
• Part of a roof, fence, soffit, cladding, or baseboard system that is failing
• Contaminating soil with broken asbestos pieces

If you are planning a renovation, bathroom upgrade, roof replacement, reclad, demolition, or even a simple plumbing job through old wall linings, you should check for asbestos first.

Many homeowners only discover asbestos after a builder, plumber, electrician, or roofer turns up and stops the job. That can delay the project, increase costs, and create a bigger safety issue if the material has already been disturbed.

Can I Paint or Seal Asbestos Instead of Removing It?

In some cases, asbestos can be managed by sealing, painting, or encapsulating it. This can be a practical option where the material is stable and not likely to be disturbed.

But sealing asbestos is not a magic fix. It needs to be done carefully and only after the condition of the material has been properly assessed.

You should not water blast asbestos roofing, scrape old asbestos paint, sand asbestos cladding, or drill into asbestos sheets to “tidy them up.” Those activities can release fibres and turn a manageable issue into a serious contamination problem.

Should I Test for Asbestos Before Renovating?

Yes. If your home was built before the 1990s, asbestos testing before renovation or demolition is a smart move.

Asbestos testing can help identify whether the material is actually asbestos or just a similar-looking product. Guessing is risky because many non-asbestos and asbestos materials look almost identical.

Testing is especially important before work on:

• Bathrooms and laundries
• Vinyl flooring
• Kitchens
• Soffits and eaves
• Exterior cladding
• Baseboards
• Garages and sheds
• Roofs
• Old fences
• Demolition areas

A small test now can save a big headache later.

What Should Homeowners Do If They Find Suspected Asbestos?

If you find suspected asbestos in your home, don’t panic and don’t start pulling it apart.

Here’s the sensible approach:

1. Leave it alone Don’t drill, cut, sand, break, sweep, vacuum, or water blast it.
2. Keep people away from damaged areas If pieces are broken or lying on the ground, keep children, pets, and visitors away.
3. Take photos Photos help an asbestos professional understand what you are dealing with.
4. Get advice before renovation or removal A licensed asbestos removalist can tell you whether it should be removed, tested, sealed, or managed.
5. Use a licensed asbestos removal company For many asbestos jobs, especially Class B asbestos removal, you should use a properly licensed removalist.
