    Grant and his team did a great job underpinning my house. They were friendly, kept us up to date at all stages and answered all the questions that we had. I would highly recommend Grant and his team. They go above and beyond, deliver exactly what they say they will and also provide great value. And as a bonus, are just super lovely to work with!

    Grant from Compete Underpinning inspected my property as I thought I needed underpinning. His assessment was that I didn't need to proceed as the cracks would be easily fixed by a plasterer. What refreshing honesty! Saved me over $14000 that another company had quoted. I had another assessment who also agreed with Grant that my cracks didn't warrant that expenditure. Would highly recommend getting this company to inspect your home if you have concerns about cracking and know that you'll get a honest assessment.

    Grant recently completed a job for me with an outstanding result. Communication throughout the whole process was excellent, price was good and this is the first contractor I've dealt with who has consistently turned up when they said they would. I cannot recommend these guys highly enough.

    Grant and his team recently completed an underpinning job to our circa 1910 property. It had sunk in the front corner and had some serious slope and massive cracks. 1 week later you could barely tell where the cracks were. Grant was informative down to earth and didn’t beat around the bush when providing a quote and explaining the process. Fantastic work and would not hesitate to recommend him to others who have a similar situation.

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.
