TG Building & Carpentry did a major renovation work for our single storey house recently, which included a complete makeover of the kitchen, laundry, bathroom, new roof, windows, flooring, lightings, skylights, remodel internal structure, back extension, external rendering, cladding and painting. It is not easy to find an honest reliable builder that can accommodate our requirements and needs.
However, we decided to give Tony a chance to take on this challenging project which was not an easy one. Throughout the process Tony was cooperative and willing to listen to our needs. He is flexible and

We have recently had a second storey addition to our home in Baulkham Hills. After our very 1st meeting with Tony we were confident we had found the right builder for the job! I cannot speak highly enough of the professional manner in which Tony displayed himself throughout the entire process, we can honestly say there was not 1 hick up! All… tradesmen were punctual, courteous and the workmanship was faultless. Tony we cannot thank you enough for the beautiful home you have made possible. I highly recommend the service's of TG Building and Carpentry.

We commissioned Tony and his team for a garage conversion and laundry reno. The team was responsive and finished the build to a high standard. We were very pleased with the end result and can't recommend TG Building & Carpentry highly enough!

Tony was very reliable and professional. His workmanship was great and completed the job on time. He kept us up to date on progression and gave useful suggestions on our renovation. We would definitely call on him again when we have other reno jobs to do.
