    We engaged Quantum Built to renovate 3 bathrooms in our 2-storey Victorian Gothic home. The renovations proved challenging, with an old house hiding building secrets that required much remedy. Quantum Bulit managed all the issues our home threw at them and delivered us 3 elegant bathrooms that we now delight in using. The Quantum Built team were responsive and good to deal with. I am happy to recommend them as a quality renovator.

    The team from Quantum Built exceeded our expectations! Quantum delivered an extraordinary makeover to our dark and dated townhouse. The works included taking out load bearing walls, structural beam installation and relocating services for 2.5 bathrooms and transforming the kitchen, dining and laundry into an open plan sunlit entertaining area. Quantum were reliable, professional, and accommodating all the way. The team delivered on every promise they made. They turned up when they said they would, stayed on target for the promised timeline and the on-site project manager kept me informed and consulted through every stage. I had the scope to pick the products and finishes I wanted with great experienced advice to support my decisions. All the tradies were polite and cleaned as they went to the extent that a several neighbours commented how clean the site and common areas were; and how quickly it all happened! Quantum were also supportive of the council Complying Development Consent approval process from the application to meeting all occupancy certification requirements. We love our new home and couldn’t be happier with the service and after service of Quantum Built.

    Jason, Karam and the whole team at Quantum Built were excellent to work with. As first time renovators, we were so lucky to choose a building company that delivered on time and that took so much care in making sure we were happy. Our main objective was to create a spacious and comfortable master suite and it is superb. We absolutely love it. The second level comprises of two other rooms and a second bathroom. And downstairs received some additional TLC. We would highly recommend Quantum Built.

    I would recommend Quantum Built to anyone who is considering embarking on a new build or renovation. Jason and Karam and the rest of the team at Quantum Built clearly take pride in the work they deliver. They were highly professional and easy to deal with throughout, and the quality of their workmanship and attention to detail were second to none. They were always easy to communicate with, and solutions- driven. Our building is an old 1930s apartment building which comes with a lot of unexpected issues, and they always took these things in their stride with professionalism. They understood exactly the outcome we wanted to achieve, and we are so happy with our new home.

    From initial consultation, to quote and completion, Jason and the team from Quantum Built were excellent communicators, understood our budget and offered us options for materials, finishes and fittings that made the whole process easy and accessible for us. Professional plans really helped us visualise the final result and throughout the project the team kept us informed, asked our opinions on variations, made recommendations as needed and accommodated our varied colour scheme. We’ve gone from a shabby semi to a beautifully finished home. We highly recommend Quantum Built.

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.
