Choosing a bathroom renovator in inner Brisbane: the three short questions

How to vet a bathroom company in inner Brisbane before they price the job. QBCC licence class, the named waterproofer, the warranty in writing, and the three questions that sort renovators from tile-over merchants in under a minute.

Short answer: hire on three things, not on the lowest number. Check the QBCC licence class on the public register. Ask who the licensed waterproofer is, by name, on your job. Ask for the warranty in writing, with the certificate handed over at the end. If a company will not put any of those three on paper before you sign, the bathroom is not really for sale yet.

Why this is the call that matters

Inner Brisbane is hard on a bathroom. The summer humidity sits in the room for months. The frames in older Queenslanders move when the air dries out in winter. The cost of getting it wrong is rarely the tiles. It is the joists, the wall studs and the ceiling below when the membrane fails behind the screed. Choosing the renovator is the only choice you make twice, before the work and after.

The QBCC licence, plainly

Queensland regulates building work through the QBCC. A bathroom renovator running the contract needs the right builder class. The waterproofer needs a separate class on the same job. The plumber holds a QBCC plumbing licence. The electrician is licensed through the ESO. Every one of those licence numbers is public, free to check, and listed on the QBCC and ESO sites. A company that hesitates to give you the numbers is the answer.

The three questions, in order

Ask these three before anyone takes a tape measure to your room. They sort the field in under a minute.

1. Who is doing the waterproofing on my job, and what is their licence number? A licensed waterproofer must be named, not the head contractor. The membrane is the part that fails when a renovation fails. The system used (Ardex, Davco, Mapei or a peer) belongs in writing alongside the name.

2. Will I receive the waterproofing certificate at handover? The certificate is a one-page document the waterproofer signs after the membrane is laid and the flood test passes. Insurers ask for it. Building inspectors ask for it on resale. A renovator who cannot promise the certificate has skipped a step you cannot see.

3. Is the price fixed and itemised before demolition starts? A fixed price names every fixture by brand and model, the tile range with the laying pattern, the screed and falls, and the strip-out and disposal. The cowboy version uses words like "quality fittings" and "PC allowance". The first kind ends at the number on the cover page. The second kind grows.

What a good visit feels like

A renovator who knows what they are doing measures, photographs, and asks more questions than you do. They want to see under the vanity, behind the toilet and at the wet wall. They lift a corner tile if the previous job is suspect. They walk you through the order of the work before they price it. Then they go away and write the proposal in days, not minutes. A salesperson who knocks out a number on the spot has not priced your bathroom. They have priced the average bathroom and added a margin for surprise.

Red flags that show up early

The cash-only deposit. The verbal warranty. The price that is half the other two for "the same job". The page-one quote with no fixture brands. The renovator who will not name the waterproofer. The promise to "look after you" instead of issuing a certificate. None of these are dealbreakers on their own. Two of them on the same job is the bathroom you pay for twice.

What to do next

Read the cost guide so you walk in with the bands in your head. Read the work guide so you know what the sequence should look like. Then book one good consult, not five mediocre ones. We design to your band, we name our waterproofer, and we hand the certificate over with the keys.

Common questions

What QBCC licence class does a bathroom renovator need in Queensland?
The work usually needs a builder with the Builder Open or Builder Low Rise class for the head contract. Waterproofing carries its own class. The licensed plumber and electrician hold their own QBCC and ESO licences. Ask for every licence number and check it on the QBCC public register before you sign.
How do I tell a renovator from a tile-over merchant?
A renovator strips back to sound substrate, recertifies the waterproofing and gives you the certificate at handover. A tile-over merchant lays new tiles on top of the old membrane, photographs the result and leaves. The first job lasts twenty years. The second leaks quietly into the frame and is paid for twice.
How many quotes should I get for a Brisbane bathroom renovation?
Two or three good ones beat five bad ones. Look for the same five lines on every quote: who waterproofs, what the membrane is, which fixtures by brand and model, the warranty in writing, and the fixed total without PC sums. Numbers you can compare like for like are the only numbers worth comparing.
How long has Waterline been renovating Brisbane bathrooms?
Since 2014, almost all of it inside ten kilometres of the CBD. Every job ships with a 10-year waterproofing and workmanship warranty, the waterproofer named on the proposal, and the certificate handed over on the day we hand back the keys.
