    This company is at work repairing some water pipes in our property in Mangerton NSW. Very professional and neat workers. We are very happy with their aptitude to work and cleanliness.

    Interflow carried out the provision of water and sewerage to 13 blocks each of which had different owners. We formed an owners' group to try to get services to our blocks. Our most positive experience in the four year process was by far working with Terri Sommerville and Interflow. They were transparent, efficient and very helpful. Lynne & Vin De Celis

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.
