EXCELLENT Based on 13 reviews Posted on Lucy YoungTrustindex verifies that the original source of the review is Google. We recently hired Oakmont Building to remove our old double garage doors and replace them with a single new door, and we couldn’t be happier with the results. From the initial consultation to the final installation, the entire process was smooth and professional.Posted on Adam TaskerTrustindex verifies that the original source of the review is Google. A recent renovation of our laundry/second bathroom was undertaken by Tom and the crew at Oakmont Building Group, and we couldn’t be happier with the result. The quote was very reasonable, and before we accepted it, Tom took the time to walk us through a few minor issues that could arise. I’m so glad they did — that upfront honesty and attention to detail gave us real confidence before any work even began. The team completed the job a few days ahead of schedule and to a level of professionalism you’d expect to see in a Sydney Harbour mansion. The workmanship, communication, and overall experience were outstanding. Highly recommend Tom and the Oakmont team.Posted on Heather CameronTrustindex verifies that the original source of the review is Google. Tom and the boys have done a few jobs for us now and the work is always amazing and they have great ideas for value adds we haven’t thought of. Couldn’t reccomend more, I’d use them every timePosted on Nick HealeyTrustindex verifies that the original source of the review is Google. Tom and his team recently completed an extension for my house in Bowral. Tom is always quick to answer my questions, provided good timelines and was transparent around pricing. The quality of their work was top notch. I recommend Oakmont for your building needs in the Southern Highlands.Posted on Sophia LazzariTrustindex verifies that the original source of the review is Google. After a long period living overseas, we returned to the Southern Highlands to renovate a humble cottage in a garden with a lot of potential. From the start we connected with Tom. He was friendly, collaborative, genuine and took the time to understand the feeling we wanted to create for our home. Tom and Brendan gave us honest advice throughout and shared their opinions rather than telling us what to do. On many occasions we consulted with Tom about other projects around our property and he was invariably gracious and helpful. Tom’s expertise, particularly with traditional finishes was obvious and he gave us solid advice that we followed. Tom’s knowledge and attention to detail has resulted in an absolutely beautiful space for our family - we love it. It was a pleasure to have Tom and Brendan working on our home and we look forward to tackling future projects with them.Posted on Jess OrieTrustindex verifies that the original source of the review is Google. I can’t speak highly enough of Tom and the team at Oakmont Building. They recently completed a full house renovation for me, and the experience was exceptional from start to finish. Tom’s communication throughout the project was outstanding—clear, consistent, and always honest. He takes real pride in his work and genuinely cares about delivering the best result for his clients. I've been a designer for many years and it’s rare to find someone reliable, and easy to work with. Nothing was ever too much trouble, they turned up when they said they would, and the quality of workmanship across the board was fantastic. I wouldn’t hesitate to recommend him and his team to anyone looking to renovate or buildPosted on Cathy BurkeTrustindex verifies that the original source of the review is Google. We had a serious problem with a collapsed veranda and stairs. Apparently they’ve never been properly waterproof. Tom provided rapid service and a very thorough quotation. The price was also reasonable. The job was done on time . The quote had been extremely accurate . The cost was pretty much exactly what the quote had been. The follow up painting service was also of excellent quality They worked quickly and without interfering with our lives at all I would happily recommend Oakmont building to anyone in the southern Highlands or the Illawarra Look out for this logo.Posted on Keegan EcklerTrustindex verifies that the original source of the review is Google. We had the pleasure of working with Tom and the team at Oakmont Building, and we couldn’t be more pleased with the results. Their professionalism and quality of work are truly outstanding. Our project involved installing a fireplace and mantelpiece, as well as transforming an old garage shed into a fully functioning studio. From the initial quote to the final handover, Tom demonstrated clear communication, attention to detail, and a strong commitment to delivering excellent results. He also took the initiative to coordinate with additional trades when needed, keeping us informed throughout the process. Any unforeseen issues or extra work were always discussed with us beforehand, ensuring full transparency and peace of mind. We highly recommend Oakmont Building for any building or carpentry needs. Their dedication, reliability, and craftsmanship set them apart.Posted on Jason VieiraTrustindex verifies that the original source of the review is Google.
