Renovation
EXCELLENT Based on 60 reviews A M2025-06-30Trustindex verifies that the original source of the review is Google. We recently had our house extension (3 rooms on ground floor) completed by Extension Unlimited. We couldn’t be happier with the results. From start to finish, Nick was professional, reliable, and very responsive to requests and clarifications. Nick and his team were very understanding and offered great suggestions and delivered high quality. Ritchie's workmanship has been excellent and the attention to detail really shows. The team kept disruption to a minimum, which made a big difference with a family still living in the house. We are very happy with the new build and would highly recommend them to anyone considering a home extension. Ar-Janine Bacanto2025-06-26Trustindex verifies that the original source of the review is Google. Our experience with Extension Unlimited is exceptional to say the less. The team is very professional, listen to our needs, explain every step-in details and given us a great comfort and fabulous results. • Starting from the reception who explained each step of the process. • Ted, the designer was very patience listening to our needs and requirements and came up with a great design. Making a few changes was not a big deal to him. • Penny who finalized the contract, permit application etc was great to work with. She explained every step thoroughly and gave us lots of comfort. • Ritchie and Travis – great team of carpenter who are always happy to come to work, did a great job and always clean and tidy up. Always explained in detail when we had any questions. A joy to work with. • The contractors of electrician, plumber, plaster, roof plumber and tiler engaged by Extension Unlimited are efficient and professional. • Nick our project manager – I had worked with a few sites managers in the past on various projects, but none can compare to Nick. His biggest interest is on client’s satisfaction and achieving excellent results. He kept us always informed on job schedule. The response time on phone calls and messages was always so quick and precious. He is a great leader of the team. • I strongly recommend Extension Unlimited to anyone. Matt Armstrong2025-06-04Trustindex verifies that the original source of the review is Google. I highly recommend Extensions Unlimited if you are looking to give your home a new lease on life and expand it to meet your family needs. Our extension was a complicated one, and completely transformed both the look and the functionality of our home. It is now a place we are proud to call our home! The EU staff and recommended contractors were amazing. Ted worked with us tirelessly to fine tune the design to meet our budget, whilst providing the "WOW". Emilio (our project manager) was a pleasure to work with and always had a solution for those head scratching moments. EU are a one stop shop having all experts under the one roof, which saved us both time and money. Luke Kennedy2025-04-12Trustindex verifies that the original source of the review is Google. We highly recommend Extensions Unlimited to anyone looking at either a big or small extension. The entire process from the initial enquiry with Sandy, design stage with Ted and construction phase with Nick was easy yet clear and detailed. We couldn't speak highly enough of Nick and his construction team. They are fantastic people, reliable and trustworthy. Jackson and Nicko were fantastic. Throughout the build we were consistently updated by Nick on what was happening and when. If there was a change in schedule it was communicated promptly and we always knew what was happening and when. 5 stars to all of the team at Extensions Unlimited. BabyG2025-03-23Trustindex verifies that the original source of the review is Google. We have had a wonderful experience with this company, starting with Spiro, and through out the entire build with the amazing team of Brett and his Team ( special mention to Jack). They always kept our comfort and safety in mind the whole time, even our fur babies and grown up kids were always kept comfortable and safe throughout the whole building period. We undertook a huge job with this company and essentially rebuilt our whole home and the final product is a fantastic custom home exactly as we imagined it. Thank you for making our dreams a reality and being so professional and thorough with your work. We can thoroughly recommend this team to anyone who is planning any sized renovation/extension.
