Essential Safety Steps Before Drilling Into Old Walls or Ceilings

Picking up a drill in an older Brisbane home feels routine. But if that home was built before 1990, it could be one of the most dangerous things you do. At Total Asbestos Removal Brisbane, we have seen first-hand how a single hole in a wall can trigger a serious asbestos hazard. Here is what you must do before any drilling begins.

Key Takeaways

• Age of the home matters most: Pre-1990 homes very likely contain asbestos in walls, ceilings, and eaves.
• Assume it is there: If you cannot confirm a material is asbestos-free, treat it as if it is.
• Test before you drill: Material sampling and laboratory analysis is the only reliable method of confirmation.
• Ordinary dust masks are not enough: P2-rated respirators are the minimum standard for any asbestos work.
• If in doubt, call a professional: Licensed removalists and assessors remove the risk entirely.

Why Drilling Is One of the Highest Risk DIY Actions

It seems harmless. A single hole to hang a picture, run a cable, or mount a security camera. But as Region Illawarra reported in November 2025, even simple tasks like drilling into eaves to install security cameras can release life-threatening asbestos fibres. The federal government’s Asbestos and Silica Safety and Eradication Agency has flagged this as an area of growing concern as homes with asbestos-containing materials continue to age and deteriorate.

A major study published in the Medical Journal of Australia on asbestos exposure during home renovation in NSW, found that over 60 per cent of DIY home renovators reported exposure to asbestos during renovation work, with more than 20 per cent reporting that their partner and children were also exposed. Only 12 per cent of those renovators regularly used respiratory protection.

Those numbers are alarming. They reflect what happens when people simply do not know the risk is there. The good news is that the risk is entirely manageable when you take the right steps before reaching for a drill.

Step 1: Find Out When Your Home Was Built

The most important first question is straightforward: when was this home built or last renovated? Asbestos-containing materials were used extensively in Australian construction until the late 1980s. As reported by Workplace Health and Safety Queensland’s compliance audit announcement, any building constructed before 1990 is likely to contain asbestos, and the older the building, the more deteriorated those materials are likely to be.

Use council records, building certificates, or the previous owner’s documentation to establish the build date. If you cannot confirm the date or the materials used, the safest approach is to assume asbestos may be present.

Step 2: Identify What You Are Drilling Into

Not all walls and ceilings in older homes are the same. Before drilling, try to identify asbestos risks by determining what material you are dealing with. Common asbestos-containing materials in Queensland homes include:

• Fibro (fibrous cement) sheeting in internal and external walls.
• Textured ceiling coatings, particularly in living areas and bedrooms.
• Bathroom and wet area wall surrounds.
• Eaves and soffits around the perimeter of the home.
• Laundry and kitchen wall panels.

Many people underestimate how easy it is to disturb asbestos during routine DIY jobs. Asbestos-containing materials can look identical to materials that do not contain asbestos. Appearance alone is never a reliable guide.

Step 3: Get a Professional Asbestos Assessment

Before any drilling takes place in a pre-1990 home, the material in question should be assessed and sampled by a licensed professional. A licensed asbestos assessor will:

• Inspect the material and assess its condition.
• Take a controlled sample for laboratory analysis at a NATA-accredited facility.
• Provide written confirmation of whether the material contains asbestos.
• Advise on safe work procedures or recommend removal if the material is in poor condition.

Professional asbestos testing service at Total Asbestos Removal Brisbane gives you a clear, documented answer before any work commences. This is the only way to know for certain what you are dealing with.

General public, including DIY renovators, are becoming the next group to develop asbestos-related disease in Australia. The university’s research led to the creation of the Australian Asbestos Network to address this very gap in public awareness.

Step 4: If Drilling Proceeds, Use the Right Equipment

If testing confirms the material does not contain asbestos, or if a safe work procedure has been established by a qualified assessor for non-friable asbestos, the following equipment standards apply when any work near suspect materials proceeds:

• Respiratory Protection: A P2-rated half-face respirator is the minimum requirement. Ordinary dust masks provide no protection against asbestos fibres.
• Disposable Coveralls: Full-body coveralls with elasticised cuffs and a hood prevent fibres settling on clothing or skin.
• Safety Glasses: Eye protection prevents fibre contact with eyes during any dust-generating work.
• Boot Covers: Prevent fibre transfer to other areas of the home via footwear.

The Queensland Government guidance specifically for drilling asbestos-containing material, recommends using a hand drill over a power drill where possible, as power tools generate significantly higher quantities of airborne fibres during drilling. Applying a foam or gel to the drill entry point before starting can also help capture fibres at the source.

Step 5: Control the Area Before Starting

Whether or not asbestos has been confirmed, basic area control steps should always be in place before any drilling begins in an older home:

• Close doors to prevent dust spreading to other rooms.
• Remove furniture, soft furnishings, and items that could trap dust.
• Lay a drop sheet beneath the work area to capture debris.
• Ensure children and pets are away from the work area at all times.
• Keep the number of people present to an absolute minimum.

These precautions apply regardless of whether asbestos has been confirmed, because the risk cannot be entirely eliminated in an older home without laboratory testing.

Step 6: Consider Whether Drilling Is Actually Necessary

Before any work proceeds, ask one important question: is drilling actually necessary here? In many cases, there are alternative approaches that do not require disturbing a wall or ceiling at all.

For example:

• Wiring can often be rerouted along non-asbestos surfaces or through conduit.
• Picture hooks can be relocated to areas confirmed as asbestos-free.
• Security cameras can be positioned on eaves that have been confirmed clear through testing.
• In some situations, removal of the asbestos-containing material before drilling may be the more practical long-term solution.

Many of the home renovation exposures that are now causing mesothelioma diagnoses in Australia involved people who simply did not recognise the risk before starting work. The decision to pause, assess, and seek alternatives is genuinely life-saving.

Conclusion

No renovation job is worth gambling with your family’s health. Before you drill into any wall or ceiling in a pre-1990 Brisbane home, speak with a licensed professional first. Contact us today for testing, assessments, or professional removal.

FAQs:

Is it safe to drill into old walls if you cannot see asbestos?

No. Asbestos is invisible without laboratory testing. You cannot confirm its absence by sight alone.

What should I do before drilling into a wall in a pre-1990 home?

Arrange professional asbestos testing first. Only proceed once a licensed assessor confirms the material is safe.

Can a standard dust mask protect against asbestos fibres?

No. Standard dust masks offer no protection. Only P2-rated respirators compliant with Australian Standard AS/NZS 1716 are suitable.

How do I know if my ceiling contains asbestos?

The only reliable method is laboratory analysis of a sample taken by a licensed asbestos assessor.

Can I drill through asbestos cement sheeting myself?

Queensland regulations do not prohibit it, but licensed removal before drilling is strongly recommended to eliminate all risk.

How long after asbestos drilling exposure can health problems develop?

Asbestos-related diseases typically develop between 20 and 60 years after initial exposure, making prevention critical.
