FAQ TO BUILDING WITH CONFIDENCE!
Have questions? We’ve answered some of the most common ones below to help you feel informed and at ease before deciding if we are right choice for you.
1. What types of projects do you take on?
We specialise in high-end home renovations, extensions and custom builds across the Illawarra and Southern Highlands, along with many other small carpentry works. If you are looking for exceptional quality and a tailored experience, we’d love to hear from you.
2. Do you offer design services, or do I need to bring my own plans?
We’re flexible!
You’re welcome to bring your own plans, or we can connect you with our trusted network of engineers and interior designers.
Either way, we work closely with your design team to ensure your plans are buildable, budget-friendly, but most of all, beautiful.
3. What areas do you service?
We primarily work across the Illawarra and Southern Highlands regions however, if you are outside of this area, get in touch – we may still be able to help!
4. How long will my renovation or build take?
Timelines depend on the scope of your project. Generally, a standard bathroom renovation takes approximately 3 weeks, and a standard kitchen renovation takes approximately 4 weeks. During your initial consultation, we provide a clear estimate based on similar past projects – and once we are underway, you’ll receive a full project schedule with key milestones.
5. Will I receive regular updates during the build?
Absolutely! Communication is one of our top priorities. You’ll receive consistent updates and be kept in the loop every step of the way so you will always know what is happening on-site.
6. Do you offer fixed-price contracts?
Yes, wherever possible we provide a fixed-price contract with clear inclusions and exclusions – no guesswork, no hidden surprises. For renovation work where unknowns may exist, we will flag potential variations upfront and guide you through every decision.
7. Is your work insured and licensed?
8. Can I live in my home during a renovation?
It depends on the scale of the renovation. In some cases, partial occupancy is possible – but for larger projects, we often recommend alternative accommodation to ensure your comfort and safety (and avoid delays). We’ll advise you early on what to expect.

EXCELLENT Based on 9 reviews Nick Healey2025-08-06Trustindex 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. Sophia Lazzari2025-08-05Trustindex 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. Jess Orie2025-08-05Trustindex 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 build Cathy Burke2025-07-30Trustindex 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. Keegan Eckler2025-07-24Trustindex 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. Jason Vieira2025-07-15Trustindex verifies that the original source of the review is Google.

Karen Every2025-07-05Trustindex verifies that the original source of the review is Google. We just had our bathroom renovated by Tom and the team at Oakmont Building Group, and we’re really happy with how it turned out! The whole process was easy and stress-free. Tom was great to work with—he listened to what we wanted and gave some awesome ideas to make it even better. The team did a fantastic job with the details and kept everything clean while they worked. Our new bathroom looks amazing, exactly what we hoped for. We’d definitely recommend Tom and Oakmont Building Group if you’re thinking about a renovation or a new build. Thanks so much for making our bathroom look so great! Gavin Lowcock2025-05-12Trustindex verifies that the original source of the review is Google. I can thoroughly recommend Tom and his team at Oakmont Building after them completing a large renovation for us that took about 6-7months. Nothing was too much trouble for the team and they were really flexible if I asked them to change something or gave them an extra job. Tom came when he said he would or communicated with me if he was delayed. Like all Reno’s , we encountered some problems but Tom and his team efficiently worked their way through them . Tom took pride in his work, was thorough and was always customer focussed. He even ended fixing some issues that weren’t really his problem. He had great communication and handled timing of all the various trades that came on site. Maybe a small thing to some people but we also really appreciated Tom and his team avoiding using any bad language while on site. Tom and his team were very personable and we honestly felt he made a stressful Reno (as we lived in the house while it was done) much more tolerable. I have no hesitation in recommending Oakmont Building for any job big or small.
