Before Removing Old Tiles in Canberra: An Asbestos Safety Checklist

Removing tiles does not disturb only the visible tile. A demolition tool may also break the sheet behind a shower wall, old vinyl under a later floor, a levelling compound, adhesive, pipe insulation or debris concealed in a cavity. Some of those materials were historically manufactured with asbestos.

This is not a do-it-yourself asbestos removal guide. It is a pre-demolition decision guide: how to identify the need for assessment, what the ACT rules change, and what records should exist before a tiler receives the exposed surface.

Use the correct ACT age triggers

Two official messages are relevant, and they answer different questions.

The ACT Asbestos Advice Notice applies to homes built in or before 1990 and shows common residential locations. WorkSafe ACT also states that a business carrying out domestic refurbishment must assume asbestos is present in an ACT property built before 2003, identify material likely to be disturbed and arrange removal before refurbishment starts.

The practical conclusion is simple: do not treat 1990 as proof that a later Canberra property is clear. Record the original construction year and all known renovation dates, but let a licensed asbestos assessor decide the investigation required for the actual strip-out scope.

Know what may be hidden around a tiled area

Possible locations listed by Australian and ACT authorities include:

• wall and ceiling sheets in bathrooms, laundries and kitchens;
• backing sheets behind wall tiles and splashbacks;
• vinyl floor tiles and backing beneath later floor finishes;
• mastics, sealants, putties and adhesives;
• patching compounds and textured coatings;
• insulation around hot-water pipes;
• electrical panel components and nearby service enclosures;
• loose debris from earlier alterations inside cavities.

This list is a prompt for assessment, not a visual identification chart. New-looking tiles can sit over an older layer. A grey, black or cream adhesive is not asbestos merely because of its colour, and an apparently modern sheet cannot be cleared by appearance alone.

Do not sample an unknown layer yourself

The national asbestos agency states that visual inspection cannot confirm asbestos; confirmation requires a sample tested by an accredited laboratory. In the ACT, asbestos identification, risk assessment, air monitoring and clearance inspection are licensed asbestos-assessor work.

Avoid the common mistake of breaking off “just a corner” for a laboratory. Sampling itself can release fibres and can contaminate the room if it is not planned and controlled. Give the assessor the proposed demolition boundaries so the survey looks at everything likely to be disturbed, not only the most obvious wall.

Useful information for the assessor includes:

• property construction and renovation dates;
• the sales-contract Asbestos Advice Notice or previous reports;
• photos of every tiled plane, adjoining cupboard and service penetration;
• whether the work removes only tile, or also sheet, screed, vinyl, wall framing or plumbing;
• locations where earlier layers are visible without further disturbance.

ACT does not use the usual under-10-square-metre DIY rule

General Australian guidance often discusses an exemption for a small quantity of non-friable asbestos. WorkSafe ACT explicitly says the ACT removed that model-regulation exemption: asbestos removal at residential and commercial premises must be performed by an appropriately licensed asbestos removalist, apart from a narrow exception for work incidental to declared minor or routine maintenance.

A bathroom wall is not automatically minor maintenance because it is small. Do not ask a handyman, tiler or homeowner to “take care of one sheet” unless the person and the work genuinely meet the ACT requirements. Check the current WorkSafe ACT register:

• Class A removalists can remove friable and non-friable asbestos;
• Class B removalists can remove non-friable asbestos only;
• a licensed asbestos assessor performs identification and the assessment, monitoring or clearance work required for the scope.

The assessor and removalist are different roles. Ask who will provide each document rather than assuming one licence covers the entire process.

Create a stop-work rule before demolition

Put a short unexpected-material clause into the demolition scope. Work stops if anyone exposes an unidentified sheet, vinyl layer, adhesive, insulation or suspicious dust outside the assessed area.

If unexpected material is found:

1. stop tools and keep people away from the area;
2. do not drill, grind, sand, dry-sweep or use a household vacuum;
3. do not carry fragments through the house or put them in a general-waste bin;
4. avoid further disturbance and contact the licensed assessor or the responsible contractor;
5. expand the assessment and removal scope before work resumes.

WorkSafe ACT places the duty on the business carrying out the refurbishment to identify and remove asbestos likely to be disturbed. A homeowner can ask for evidence and make the site information available, but a contractor cannot transfer its work-health-and-safety duty to the homeowner with a checkbox.

Define what “ready for tiling” means after removal

An asbestos clearance does not automatically mean the substrate is ready for tile. It addresses the asbestos-removal scope; the exposed surface still needs a separate construction assessment.

Before the tiler quotes the rebuild, record:

• the assessor's report and the exact surveyed area;
• removalist business, licence class and removal scope;
• clearance documentation required for the work;
• photographs after removal and before new linings conceal the structure;
• remaining adhesive, damaged framing, corrosion, moisture or unsuitable sheets;
• the planned substrate, waterproofing and service repairs;
• any restrictions on drilling or disturbing adjacent retained materials.

Do not let the removal allowance silently become a promise that every wall will be straight, dry and ready to tile. Hidden-condition decisions should be priced and approved after exposure.

Keep the waste path separate from normal demolition waste

ACT City Services classifies asbestos as hazardous waste and states that it must not enter recycling, garden-waste or general-waste bins. The licensed removalist should plan compliant packaging, transport and disposal for the actual load and current facility requirements.

Ask for the disposal path in the removal quote. Do not use a skip-bin label or a pile wrapped by an unlicensed person as evidence of lawful disposal.

A homeowner pre-demolition pack

Prepare these items before inviting demolition quotes:

• property address, type and construction year;
• previous renovation, asbestos and loose-fill information;
• a marked plan of the exact surfaces to be removed;
• photographs of walls, floors, ceilings, penetrations and adjoining spaces;
• the licensed assessor's survey or a clear allowance to obtain one;
• a written stop-work process for unexpected material;
• responsibility for removal, clearance, waste and post-removal repairs;
• the substrate condition required before waterproofing or tiling starts.

After the hazardous-material scope is resolved, use the ACT bathroom approval checklist to coordinate the remaining approvals and licensed services. LITA Tiling can assess the tile build-up through its Canberra bathroom tiling service once the area is lawfully cleared and the exposed substrate can be inspected.
