“We build homes and lasting relationships.”

What a fantastic experience with Brendan and the team. From start to finish, Brendan’s communication, professionalism and attention to detail was amazing. Brendan kept me well informed through out the reno, trades all turned up on time and were all fantastic. As this was our first renovation, was a little apprehensive, however I couldn’t be happier with the end result and the entire process. I will definitely be using Brendan and the On Q Building Group again and would highly recommend to anyone looking to complete a renovation. Thanks Brendan for a fantastic end result and a great experience.

Brendan and his team were amazing to work with. Having never gone through a reno before they made the process much easier and enjoyable than I was anticipating. They listened to my numerous questions and answered them anytime of the day with a phone call which was very appreciated. They listened to my ideas and gave appropriate advice based on their experiences. Loved his attention to detail and commitment to providing the best quality product even to the smallest detail; even if it took up a bit more of his and his team’s time. I will definitely love to have On Q work on other projects around my house in the future. Thank you!

Had the great experience and joy of working with Brendan and his team on a double bathroom renovation in June 2024. The bathrooms needed to be salvaged from a poor renovation job that left us with leakages and other unpleasant results. Brendan presented to be very knowledgeable, knowing immediately what needed to be done to get us to a compliant and also aesthetic bathroom that will last forever. Every detail was discussed over a meeting, pricing was fair and transparent and very accommodating to personalize it to what we wanted.

Brendan and team were fantastic, efficient and on time finishing our bathroom project. Workmanship on par and beautifully finished.

We found the OnQ Building Group from Google Searches and saw the amazing google reviews from other customers. We were not disappointed.

The process was easy, with a tradie schedule provided. We are extremely happy with the results.

We recently had our ensuite bathroom renovated by ONQ Building Group and are thrilled with the outcome. Brendan was incredibly patient, flexible, and always on standby to answer any questions we had throughout the process. His professionalism and attention to detail made the entire experience smooth and stress-free. Highly recommend!

Brendan and his talented team at On Q renovated entire our home to exactly what we wanted for our busy family. In some cases they went above and beyond what our expectations were. We had an agreement and a plan to complete the project within a short time period and On Q delivered on what they said they would do. Attention to detail and the finished product was of the highest quality and we look forward to working with On Q for our next project.

Brendan was fantastic to deal with every step of the way. Everything happened when he said it was with no delays. I would highly recommend ONQ Building to anybody looking for somebody reliable, trustworthy and skilled. Five stars.

Brendan and the team at On Q just completed my parent’s bathroom and what an amazing job. Communication, timing and quality of works was better than expected and we could not be any happier with the result. A big thank you to Brendan, as after searching for almost 18 months and 9 quotes later everything was perfect and mum and dad are very happy. Thank you.

Brendan and the team have delivered a fantastic outcome on our plans with full transparency, quality workmanship, & within our planned budget. They were also a pleasure to work with and treated our home as their own. Rare to find tradespeople who are genuine that made the experience enjoyable.

How can I express how amazing and how easy my bathroom reno with On Q build was? I had previously been ripped off 17k from another provider and lived with no bathroom for 3 years. I was nervous trying to find a new contractor and Brendan instantly put my mind at ease. His communication was spot on, I never had to chase him (he was always calling me to give me updates), his tradies were on time and absolutely top notch! I’ve told him he’s doing all my Reno’s from now on! If you are searching for the best builder – look no further! I thought trustworthy tradies were a thing of the past – but this team is a unicorn! Well done guys and thank you again! I love my bathroom so much!
