Licensing. In NSW, wall and floor tiling is licensed trade work. A contractor licence is needed to carry out, advertise or contract for residential tiling worth more than $5,000 in labour and materials, GST included, and unlicensed work can draw fines of $22,000 for an individual and $110,000 for a company. The NSW Government describes the work as attaching tiles of fired clay, moulded concrete, ceramics or natural material to the inside or outside surfaces of a building, and includes cork, linoleum, rubber and thermoplastic tiles, mosaics, preparing surfaces and making minor repairs before tiling (but not renewing or replacing them), inserting expansion joints, and waterproofing wet areas to get them ready for tiling. The current qualification is CPC31320 Certificate III in Wall and Floor Tiling. Waterproofing is licensed as a category in its own right, covering any protective treatment that stops water or moisture getting into a home or stops water escaping from a wet area such as a shower, and its current qualification is CPC31420 Certificate III in Construction Waterproofing. Anyone can look up a licence's categories, status, expiry date and conditions on the NSW Government's Verify Licence check.
Advertising, contracts and warranties. NSW's rules on building trade advertisements cover the internet as well as print, television and radio. An ad should carry the licensee's name or a registered business name, the licence number with the right category of work and a business phone number, and it can't quote a price that is only part of the cost unless the single full price is clearly stated too. Jobs priced over $5,000 including GST need a written contract and a copy of the Consumer Building Guide before signing; the deposit is capped at 10 percent, and on work over $20,000 the contractor can't ask for a deposit or other payment until Home Building Compensation cover is in place and the owner has its certificate. Our page for Sydney builders covers those money rules in more detail. After handover, statutory warranties apply: legal action to enforce them has to start within 6 years for a major defect and 2 years for any other defect, and Building Commission NSW lists waterproofing among its examples of major defects, alongside load-bearing parts such as floors and walls, and fire safety systems. That is part of why careful owners ask which membrane you use and what paperwork they'll get.
Apartments and strata approval. The NSW Government's strata renovation guidance sorts work into three groups. Cosmetic work, such as laying carpet, needs no approval. Wood, tile or other hard flooring is a minor renovation: it needs a vote with more than 50 percent of votes cast in favour, or approval from the strata committee where a by-law allows it, and the owner provides plans with dates and times, the tradespeople's details and qualifications, and an acoustic certificate for the floor. Bathroom renovations and changes that require waterproofing count as major renovations, which only a special resolution at an annual or other general meeting can approve, with no more than 25 percent of the value of votes cast against. So an apartment bathroom can't go ahead until the owners corporation has met and voted, and a tiler who explains that timing and lists the documents they can supply is simpler to plan around. By-laws differ from one scheme to the next, so the site should send owners to their own strata manager for the specifics.
Where the strata jobs are. At the 2021 Census, about 562,000 of Greater Sydney's 1.83 million occupied homes, roughly three in ten, were flats or apartments. The mix shifts sharply across the city. In the Waverley, Randwick and Canada Bay council areas more than half of occupied homes were apartments; in Penrith and Campbelltown fewer than one in ten were, and close to four in five were separate houses. A tiler working mostly around Waverley and Randwick is likely to deal with strata approvals often, while one based around Penrith or Campbelltown will mostly be working in houses. The suburbs you list, the photos you lead with and the questions on your quote form should make your own mix plain, so apartment owners and new-home owners can each tell you've done their kind of job.
Older homes, and how we work. SafeWork NSW notes that asbestos can be found when walls come out of buildings built or renovated before 1990. A Class B licence is needed to remove more than 10 m² of non-friable asbestos, and removalists must notify SafeWork NSW when they carry out removal work. We present what you tell us about your strip-outs and link to the official pages; we don't give safety, planning or legal advice. Our team works from Hutt St in Adelaide, so Sydney tilers deal with us by phone and email: you send your licence details, a set of finished jobs and the areas you cover, and we send back a draft link to check on your phone between jobs.
