Would highly recommend ， Good communication from all departments. Jason gave us a lot of his time and good ideas, they ran the renovation smoothly, most the tradesmen they use were good to work with also. Very little issues throughout the project but any that did crop up they were understood and sorted straight away. Thanks for an easy renovation

Frequently asked questions

How much do builders typically charge?

Builder costs vary widely depending on the job type and complexity. Minor repairs are generally much less than extensions, small builds or structural alterations that need foundations, framing or specialist input. Most quotes include a call‑out fee plus labour and materials, and the page shows live pricing to help you compare options.

Do builders charge call-out fees?

Call‑out fees are common and typically cover travel and an initial inspection or assessment. This fee is usually separate from hourly labour and materials, and after‑hours or weekend attendance often attracts higher rates. Ask whether a call‑out or minimum charge applies when requesting quotes.

Do builders need a licence in Australia?

Yes. Building work generally needs to be carried out by a licensed builder in every state and territory, and NSW builders are regulated by NSW Fair Trading. Builders should be able to provide their state builder/contractor licence number and show appropriate insurances and ABN/GST registration. In Victoria, domestic building insurance is required above a state threshold for certain contracts.

Is 5J Building Group licensed?

Yes. 5J Building Group currently shows an active trade licence on SureQuote.
