Matt Champion11 January 2026Josh is extremely knowledgeable and skilled in transforming homes very efficiently and on time! Will definitely recommend to friends and family 👌Posted on GoogleMichael Addicott2 November 2025We used JG building after an extensive search comparing various builders across a few criteria such as previous projects, communication, pricing and availability. JG building came in ahead on all criteria and we we’re happy to go with Josh for our extension and renovation. Our project included an en-suite extension, whole building render, painting, floor sanding, new kitchen and white picket fence. Through the whole build, Josh was a great communicator, not just with us but with all his trades, to make sure everyone had a clear understanding of the brief. As issues inevitably arose, as they do with renovations, Josh was quick to explore options to work through them, keeping our project running on time always. The quality of the outcome Josh delivered for us was fantastic. Attached are some pictures of the journey toward modernizing our home. When we bought the home it was overgrown, dated and tired. We made conscious decisions to design our finishes with a broad based appeal in mind, and as you can see from the photos, Josh has delivered this perfectly. Josh and JG Building and Construction are highly recommended for big and small jobs, and will continue to be our builder for any future projects.Posted on GoogleAlex Burgin9 October 2025Josh was fantastic to deal with — great communication throughout the whole job and really high-quality workmanship. Everything was done when he said it would be, and the finish is spot on. Highly recommend.Posted on GoogleEmanuel Francica29 September 2025As a structural engineer, I’ve had the opportunity to work alongside JG Building on a number of projects throughout the Central Coast and Newcastle. Their team consistently demonstrates a high level of professionalism, attention to detail, and commitment to quality construction. They follow engineering specifications accurately, communicate clearly, and are proactive in resolving site challenges. From an engineering perspective, it’s refreshing to collaborate with a builder who values compliance, safety, and workmanship to such a high standard. I have no hesitation recommending JG Building to anyone looking for a reliable and skilled builder.Posted on GoogleCarl Spears31 August 2025Great service, great result! Friendly, approachable and communication was exemplary. Josh organised all the trades and everything done to schedule. Craftsmanship was impeccable. Bathroom renovation has never been easier. Highly recommend and we look forward to working with him again for our next job.Posted on GoogleShane Meister14 August 2025Josh and his crew were awesome—super easy to work with, dependable, and seriously talented. Love working with them and seeing the transformations. Highly recommend!Posted on GoogleDani Montgomery13 August 2025Josh - JG Building & Construction PTY was our builder for our new bathroom ensuite, extra building works we needed etc. We could not be happier with the outstanding work that he did, managing all his trades on time promptly and his follow-up to detail was amazing. We honestly could not fault him at any level. Would highly recommend Josh and his company to do any work for anyone and we will be using him in the future. Dani & Chris MontgomeryPosted on GoogleAnna Maguire14 April 2025Josh and JG Building did a major renovation for us (2.5 bathrooms, laundry, new flooring, wardrobes, new kitchen +++). We chose Josh due to his attention to detail when quoting that built trust. The whole job was completed in a short time frame, with great professionalism and no stress. With him managing all the trades we knew he would coordinate what needed to be done, when, and he did. We would highly recommend him. Should we ever do another house and renovation, we will be on the phone to him pronto!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
