How to choose a water damage restoration company in Sydney

Six practical checks before you hire: response speed, certification, NSW licensing for rebuild work, written quotes and door-knocker scams to watch for.

Sydney homeowners usually pick a water damage restoration company at the worst possible time: water is still spreading, the insurer is on hold, and every search result claims to be '24/7 emergency' and 'fully certified'. What actually separates a good operator from a bad one mostly shows up later, once the invoice lands or the insurer starts asking questions. Run through these checks before you sign anything.

Confirm response speed, do not just assume it

Every hour water sits in carpet, plaster and subfloors makes the job bigger, and mould can take hold faster than most people expect; our guide to the mould risk window sets out that timeline in full. So a company's claim to offer 24/7 emergency response is worth checking, not assuming: ask directly whether someone is answering that number right now, or whether 'emergency' really means a callback the next business day. If you have not yet worked through the first hour after the leak, our first 24 hours checklist is the place to start while you're still choosing a company.

Ask about IICRC certification, then ask what it changes

IICRC (the Institute of Inspection, Cleaning and Restoration Certification) is a nonprofit body that certifies restoration technicians and firms against industry standards, including S500, the standard for professional water damage restoration. It is not an Australian government licence, and a company can do good work without it, so treat the badge as one input, not a pass or fail test on its own.

What certification more reliably buys you is documentation: moisture readings, drying logs and an assessment report written to a standard your insurer recognises. If your claim is going to hinge on that paperwork, our guide to claiming water damage on your insurance sets out exactly what to ask a company to hand over and why it matters for getting paid.

Check the contractor licence if the job includes rebuilding

Extraction and drying is a service, not building work, but plenty of water damage jobs do not stop there. Replacing plasterboard, flooring, skirting or cabinetry is rebuilding, and in NSW that part of the job is regulated: a company or partnership must hold a contractor licence before it contracts, sub-contracts or advertises to do residential building work over $5,000, including GST. If your restoration company is quoting reinstatement work above that amount, ask for their contractor licence number and check it with the Service NSW licence-check tool before you sign.

That $5,000 threshold applies to the rebuild, not the initial extraction and drying call-out, so do not assume a company is unlicensed just because they turned up the same day and started drying. Ask specifically which parts of the quote are covered by which licence.

Get the scope and price in writing before work starts

A trustworthy quote itemises what is being done: extraction, dehumidification, antimicrobial treatment and any reinstatement, with the water category stated (clean, grey or black), since that category is the biggest single driver of cost. For a sense of what a fair number looks like before you compare quotes, see our Australian cost guide.

Two things are worth pushing back on. A quote that just says 'water damage restoration, $X' with no breakdown gives you nothing to check against if the final invoice comes in higher. And a company that asks for full payment upfront, in cash, before any work has started, is one you should be comfortable walking away from. Some companies bill your insurer directly, others expect you to pay and claim the cost back afterwards; ask which model applies before work starts, since it changes how much cash you need on hand in an emergency.

Watch for door-knockers after a storm

After widespread storm or flood damage, NSW's Building Commission has warned residents against accepting unsolicited offers of repairs from people who may be posing as builders or other tradespeople. The safer path is to find a company through a recommendation or an insurer's preferred list, and to check any tradesperson's licence with the Service NSW licence-check tool, rather than accepting whoever knocks on the door or calls first.

Confirm how they will prove the property is actually dry

Visually dry and instrument-dry are different things: materials can look and smell fine on the surface while a moisture meter still reads wet several centimetres into a wall or subfloor cavity. Ask whether the company takes and records daily moisture readings until the property reaches a dry standard, not just until it looks better. That record is also what your insurer or a loss adjuster will want to see if anyone ever disputes whether the drying job was actually finished.
