Choosing a builder is so important. I am so fortunate to have had North East recommend by friends who were delighted with North East. Chris did an amazing job on my place. It was a huge job. Sustainable design, cost effective, energy efficient and security. Communication was clear, honest and respectful. I cannot recommend this company enough.

North East Building Group recently completed a reasonably complicated renovation to our residence. I cannot speak more positively of Chris and his crew! The communication and their attitude was perfect and everything was completed to a very high standard and on schedule despite some third party delays. I have no hesitation in highly recommending Chris and his team to everyone!Posted on James Salmond12 September 2024Trustindex verifies that the original source of the review is Google. I was referred to North East Building Group for some difficult water damage repairs to Ben Huon Manor the work required internal plaster board repairs as well as rafters and external flashings. Chris and his team were fantastic they stayed on the task until complete delivering excellent quality in a short time. I will definitely be using them again in the future James SalmondPosted on Jonathon11 September 2024Trustindex verifies that the original source of the review is Google. Highly recommend North East Building Group. When we set out to renovate our home we wanted a builder who would work collaboratively with us and bring our vision to life. Chris and his team absolutely exceeded that brief. Not only is Chris a master craftsman who puts great care and attention into his work, he is excellent at problem solving and finding solutions (which invariably happen!). Most of all, Chris and his team are just great guys who are responsive and considered in their work.Posted on Hannah Warwick10 September 2024Trustindex verifies that the original source of the review is Google. We worked with Chris on the renovation of a 1930’s cottage in Wollongong and had such a great experience. This was a beautiful old house and Chris and his team took great care in preserving the parts we were keeping (which was most of it) and the end result was a very special home that we were so happy with. You hear so many horror reno stories but that was not our experience at all. Chris is genuine and trustworthy and will listen to all your ideas and talk them through with you. He has great attention to detail and is passionate about quality and doing things the right way. His team and all the sub-trades that he uses are all such nice guys, we enjoyed the whole reno process so much and we highly recommend Chris to anyone looking for a builder.Posted on Jan Dion10 September 2024Trustindex verifies that the original source of the review is Google. I recently had an extensive pool deck renovation. Chris & his team were brilliant to deal with. Their workmanship was excellent with exceptional attention to detail. I was so impressed with the completed job & they were such a pleasure to deal with that I have this week engaged them to do more renovations. I highly recommend this business.Posted on Teresa Massaria10 September 2024Trustindex verifies that the original source of the review is Google. I have trusted North East Building Group for a number of renovations, the latest being an extension with a new laundry and deck. Chris was very easy to communicate with and was able to provide suggestions and options to suit the house and budget. I highly recommend North East - Chris and his team's punctuality, workmanship and quality of their work was excellent, and I cannot recommend them highly enough.Posted on Annelie Watt2 May 2024Trustindex verifies that the original source of the review is Google. Chris and his team renovated our home and built us a beautiful, high quality deck. The renovations involved removing an internal wall and installing large bifold doors which open out to a large deck. The deck has completely transformed our home and garden, and doubled our living space. Chris has a great eye for design and incredible attention to detail. He helped us every step of the way with decision making, and we are super happy with the end result. The team were wonderful to work with. Communication was very smooth, and they are such a friendly group of guys - it was a pleasure to have them here working on our home. Thanks again Chris!Posted on Helena Tobbe16 April 2024Trustindex verifies that the original source of the review is Google. Chris and the boys were amazing!! Recently completed a renovation and i couldn’t be happier with the result! Chris contributed his own ideas to help me achieve the best result! Even had the great idea of restoring some of the old hardwood floor joists and making into our front door! Great work boys!
