    Great experience with Mustafa. We converted an old bar into a kitchen. Working in a space of 6m x 2m, we raised the floor to run electric and plumbing underneath. He was helpful and patient, and provided useful suggestions to improve every space. Included a large fridge, oven, stove and vented rangehood, and a serving bar, with stone benchtop and backsplash. Looks great and mum was very happy.

    Double diamond are an amazing team of tradies who delivered above and beyond our bathroom renovation expectations. Mustapha’s answer to all of my requests was ‘no problem’. I knew what I wanted in terms of design and I couldn’t have picked a better company to turn my design into reality. Thank you, Mustapha and co! We will be back.

    Thank you so much to Mustapha and his team for our wonderful new bathroom. We are so happy with everything. Especially appreciate your little extra little touches we had forgotten like black rim around door and window frame and black toilet flusher.

    Mustapha did a great job. We had some issues which meant that we had to stop the work but he was patient and accommodating. He worked with our ideas and improved on them and the end result is great. We had one glitch with the work but he jumped on it and dealt with it immediately. The job was easier than it might have been because he was so responsive and positive.

    We recently had our bathroom renovated by Mustapha and couldn’t be happier with the results! From the very beginning, Mustapha was friendly, professional, and extremely responsive. He kept us updated every step of the way and regularly checked in to make sure we were happy with the progress. The workmanship is of excellent quality – everything was finished to a high standard and exactly as we had hoped. The renovation was completed on time, and all the tradies working on site were punctual, courteous, and professional. Considering we found Mustapha online and had never worked with him before, this has been a truly positive experience. We’re absolutely thrilled with our new bathroom and would highly recommend Mustapha to anyone looking for a reliable and skilled builder!

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.
Does Double Diamond Construction have a verified ABN?
Yes. Double Diamond Construction has completed ABN verification on SureQuote.
